Choosing the right size air conditioner is one of the most important decisions homeowners can make when installing or replacing a cooling system. If the unit is too small, it may run constantly and still struggle to cool your home. If it is too large, it may cycle too quickly, waste energy, and leave your home feeling uncomfortable. At A/C Authority, we help homeowners make informed decisions about AC installation in Port St. Lucie by evaluating home size, layout, insulation, airflow, and cooling needs before recommending a system.

In Florida’s hot and humid climate, proper AC sizing affects more than temperature. It also impacts humidity control, energy efficiency, system lifespan, indoor air quality, and long-term comfort. Understanding how sizing works can help you avoid costly mistakes and choose an air conditioner that fits your home correctly.

Why AC Size Matters for Home Comfort

Air conditioner size refers to the system’s cooling capacity, not the physical dimensions of the equipment. Cooling capacity is typically measured in tons or BTUs. The right capacity allows the system to remove heat from your home efficiently while maintaining consistent comfort.

When an AC unit is properly sized, it can run in balanced cooling cycles. This helps maintain steady indoor temperatures, manage humidity, and reduce unnecessary energy use.

Incorrect sizing can lead to comfort problems that continue for years, which is why professional evaluation is so important before installation.

What Happens If Your AC Unit Is Too Small?

An undersized air conditioner may not have enough cooling capacity to keep up with your home’s needs, especially during hot Port St. Lucie afternoons.

Signs of an undersized system may include:

• AC running constantly
• Rooms staying too warm
• Long cooling cycles
• High energy bills
• Uneven comfort
• Excess system wear
• Difficulty cooling during peak heat

Because the system has to work harder for longer periods, it may experience more wear and a shorter lifespan.

What Happens If Your AC Unit Is Too Large?

Many homeowners assume a bigger AC unit is better, but oversized systems create their own problems. A unit that is too large can cool the air quickly without running long enough to remove enough humidity.

This can leave the home feeling cool but damp or clammy. Oversized systems may also short cycle, meaning they turn on and off frequently.

Short cycling can increase energy use, reduce comfort, strain components, and lead to more frequent repairs over time.

Why Square Footage Alone Is Not Enough

Square footage is an important starting point, but it should never be the only factor used to choose AC size. Two homes with the same square footage can have very different cooling needs.

Other important factors include:

• Ceiling height
• Insulation levels
• Window size and placement
• Sun exposure
• Home layout
• Ductwork condition
• Number of occupants
• Appliance heat gain
• Air leakage
• Local climate

A professional load calculation accounts for these details to determine the correct system size.

How Florida Humidity Affects AC Sizing

Humidity is a major consideration in Port St. Lucie homes. Your air conditioner does more than cool the air; it also removes moisture during normal operation.

If a system is oversized, it may not run long enough to remove humidity effectively. This can make the home feel sticky even when the thermostat shows a comfortable temperature.

Proper sizing helps the system run long enough to control both temperature and humidity more effectively.

The Role of Insulation in AC Sizing

Insulation helps slow heat transfer into your home. Homes with strong insulation typically require less cooling capacity than homes with poor insulation.

If insulation is missing, damaged, or inadequate, the AC system may need to work harder to maintain comfort. Before replacing equipment, it may be worth evaluating insulation and air sealing.

Improving insulation can sometimes reduce cooling demand and help your new AC system perform more efficiently.

How Windows and Sun Exposure Influence Cooling Needs

Windows can significantly affect how much heat enters your home. Large windows, older windows, and windows facing strong afternoon sun can increase cooling demand.

In Port St. Lucie, direct sunlight can quickly warm rooms and make the AC work harder. Homes with shaded windows, efficient glass, or quality window treatments may have lower cooling needs.

A proper sizing evaluation considers how windows and sun exposure affect each room.

Why Ductwork Condition Matters

Ductwork plays a major role in delivering conditioned air throughout your home. If ducts are leaking, damaged, poorly designed, or undersized, your AC may not perform properly even if the equipment is the correct size.

Common ductwork issues include:

• Air leaks
• Disconnected ducts
• Restricted airflow
• Poor layout
• Insulation problems
• Unbalanced airflow

Before installing a new AC unit, ductwork should be evaluated to ensure the system can deliver air efficiently.

Understanding Tons and BTUs

Air conditioner capacity is commonly measured in tons. One ton of cooling equals 12,000 BTUs per hour. A larger tonnage means more cooling capacity.

However, more capacity is not always better. The goal is to match the equipment to your home’s actual cooling load.

A professional technician can help determine the appropriate capacity based on the home’s full comfort needs rather than relying on guesswork.

Why Professional Load Calculations Are Important

A load calculation is a detailed process used to determine how much cooling your home needs. It considers the home’s structure, insulation, windows, layout, occupancy, and climate conditions.

This calculation helps prevent oversizing and undersizing. It also supports better efficiency, comfort, and equipment performance.

Choosing an AC unit without a proper evaluation can lead to long-term problems that are expensive to correct.

Signs Your Current AC May Be the Wrong Size

If your existing system has never performed well, sizing could be part of the issue.

Warning signs may include:

• Frequent short cycling
• Constant operation
• Hot and cold spots
• Poor humidity control
• High energy bills
• Rooms that never feel comfortable
• Frequent repairs
• Unusual wear on components

A professional inspection can help determine whether the problem is related to sizing, ductwork, maintenance, or another system issue.

How the Right AC Size Improves Efficiency

A properly sized air conditioner can cool your home without excessive run time or frequent cycling. This helps reduce energy waste and supports more balanced performance.

When the system is correctly matched to the home, it can operate in healthier cycles, maintain comfort more consistently, and avoid unnecessary strain.

Proper sizing is one of the most important parts of long-term HVAC efficiency.

How Proper Sizing Helps Extend System Lifespan

Air conditioners last longer when they operate under the right conditions. Undersized systems may run too often, while oversized systems may start and stop too frequently.

Both issues create unnecessary wear. Correct sizing helps reduce stress on compressors, motors, electrical parts, and other major components.

This can support longer equipment life and fewer repair concerns over time.

When summer temperatures soar in Port St. Lucie, keeping your home comfortable often means running your air conditioner for long periods each day. While reliable cooling is essential, many homeowners notice a significant increase in their utility bills during the hottest months of the year. At A/C Authority, we help homeowners find practical ways to improve efficiency, reduce energy waste, and lower cooling costs without sacrificing comfort. Proper AC maintenance services, smart habits, and home efficiency improvements can all contribute to meaningful savings during Florida’s hottest weather.

The good news is that reducing cooling costs does not always require major investments or drastic lifestyle changes. Small adjustments combined with proper HVAC care can help your air conditioner operate more efficiently and reduce unnecessary energy consumption.

Why Cooling Costs Increase During Summer

During the hottest months, your air conditioner must work harder to remove heat from your home. Higher outdoor temperatures create a larger temperature difference between indoor and outdoor air, increasing the workload placed on the system.

Longer cooling cycles, increased humidity, direct sunlight, and frequent thermostat adjustments can all contribute to rising energy bills. Homes with poor insulation, dirty HVAC components, or airflow issues may see even greater increases in cooling costs.

Understanding what drives energy use is the first step toward reducing expenses.

Replace Air Filters Regularly

One of the simplest and most effective ways to improve efficiency is replacing your HVAC air filter regularly. Dirty filters restrict airflow, forcing the system to work harder to circulate cooled air throughout the home.

When airflow is reduced, the system may run longer, consume more energy, and experience additional wear on components.

Most homeowners should inspect filters monthly and replace them as needed based on manufacturer recommendations, household conditions, and pet ownership.

Schedule Professional AC Maintenance

Routine maintenance plays a major role in keeping cooling costs under control. Dust, dirt, worn components, and airflow restrictions can gradually reduce system efficiency.

Professional maintenance may include:

• Coil cleaning
• Airflow inspection
• Electrical testing
• Thermostat calibration
• Drain line inspection
• Refrigerant evaluation
• Filter inspection
• System performance testing

A properly maintained system typically operates more efficiently and may be less likely to experience costly breakdowns during peak summer demand.

Use Your Thermostat Strategically

Thermostat settings can significantly influence cooling costs. Lowering the thermostat more than necessary forces the system to work harder and run longer.

Instead of setting extremely low temperatures, choose a comfortable setting and avoid constant adjustments throughout the day. Consistent settings often allow the system to operate more efficiently.

Even small temperature changes can have a noticeable impact on overall energy consumption.

Consider a Smart Thermostat

Smart thermostats allow homeowners to automate temperature schedules based on occupancy and daily routines. This helps reduce unnecessary cooling when the home is empty while maintaining comfort when occupants are present.

Many smart thermostats offer features such as:

• Programmable schedules
• Remote control access
• Energy usage tracking
• Automatic adjustments
• Vacation settings
• Learning capabilities

These features can help reduce cooling costs without requiring constant manual adjustments.

Keep Vents Open and Unobstructed

Some homeowners close vents in unused rooms hoping to save energy. However, this can sometimes create airflow imbalances that reduce HVAC efficiency.

Furniture, rugs, curtains, and storage items can also block airflow from supply vents and return grilles.

Keeping vents open and unobstructed helps maintain proper airflow throughout the home and supports efficient system operation.

Reduce Heat Gain from Sunlight

Direct sunlight can significantly increase indoor temperatures, especially during the afternoon. Windows that receive strong sun exposure often contribute to additional cooling demand.

Ways to reduce solar heat gain include:

• Closing blinds during peak sunlight hours
• Using curtains or shades
• Installing window treatments
• Applying window films
• Adding exterior shading where appropriate

Reducing heat gain helps the air conditioner work less to maintain comfortable temperatures.

Use Ceiling Fans Effectively

Ceiling fans do not lower room temperature, but they can help occupants feel cooler by improving air circulation. This may allow homeowners to use slightly higher thermostat settings while maintaining comfort.

Fans are most effective when rooms are occupied. Turning them off when rooms are empty prevents unnecessary energy use.

Combining fans with efficient thermostat settings can help reduce overall cooling demand.

Seal Air Leaks Around the Home

Cool air can escape through gaps around doors, windows, attic penetrations, and other openings. At the same time, warm outdoor air can enter the home, increasing cooling requirements.

Common leak locations include:

• Door frames
• Window frames
• Attic access points
• Utility penetrations
• Duct connections
• Exterior wall openings

Sealing leaks helps improve efficiency by keeping conditioned air inside the home.

Improve Attic Insulation

Insulation plays a major role in controlling heat transfer. In Florida homes, attic insulation helps reduce the amount of heat entering living spaces from above.

When insulation is inadequate, the HVAC system must work harder to compensate for heat gain. Improving insulation can help maintain more stable indoor temperatures and reduce cooling costs over time.

Proper insulation works alongside your HVAC system to support comfort and efficiency.

Keep the Outdoor Unit Clean

Your outdoor condenser unit requires unrestricted airflow to release heat effectively. Grass clippings, leaves, landscaping materials, and debris can reduce airflow around the equipment.

When airflow is restricted, the system may lose efficiency and experience additional strain.

Maintaining a clear area around the outdoor unit supports proper operation and helps the system perform at its best.

Avoid Heat-Producing Activities During Peak Hours

Certain household activities generate additional heat indoors. Cooking, baking, using ovens, running dryers, and operating heat-producing appliances can increase cooling demand.

Whenever possible, consider:

• Cooking earlier in the day
• Using outdoor grills
• Running dishwashers at night
• Running laundry during cooler hours
• Using smaller appliances when appropriate

Reducing indoor heat sources helps lessen the workload on your air conditioner.

Inspect Your Ductwork

Leaky ductwork can allow conditioned air to escape before it reaches living spaces. This forces the HVAC system to work harder to achieve desired temperatures.

Signs of duct problems may include:

• Uneven temperatures
• Weak airflow
• Higher utility bills
• Excess dust
• Hot and cold spots

Duct inspections can help identify hidden efficiency losses that contribute to rising cooling costs.

Know When It May Be Time for an Upgrade

Older HVAC systems often require more energy to produce the same level of comfort as newer equipment. As systems age, wear and declining efficiency may contribute to rising utility costs.

If your air conditioner struggles to maintain comfort, requires frequent repairs, or causes unusually high energy bills, it may be worth evaluating replacement options.

Modern high-efficiency systems often provide improved performance and energy savings compared to aging equipment.

When should I consider replacing my air conditioner?

If your system is older, frequently requires repairs, struggles to cool the home, or causes high utility bills, it may be time to explore replacement options.

The best way to buy a new air conditioner is to choose the right size system for your home, compare efficiency ratings (SEER2), and hire a licensed HVAC contractor who performs a professional load calculation before installation. This ensures you get the comfort, reliability, and energy savings you’re paying for.

When your AC quits, the pressure to replace it quickly can feel overwhelming. With so many brands, contractors, and price ranges, it’s easy to make a rushed decision that costs more in the long run. That’s why AC Authority created this Air Conditioner Buyers Guide, to help you make a confident, informed decision about one of the biggest investments in your home.

Too many HVAC companies push systems that benefit their bottom line, not your comfort. We’re here to change that by equipping you with the questions, insights, and tools you need.

Step 1: Choosing the Right Air Conditioning Company

The company you choose matters just as much as the equipment itself. Here’s what to look for:

• Reputation and Reviews – Look for at least 100+ Google reviews with an average of 4.5 stars or higher. This signals consistent quality. Ask neighbors who they trust.
• Responsiveness – Does the company answer the phone after hours or on weekends? A reliable provider should offer emergency service and same-day appointments when your home is uncomfortable.
• Qualified Technicians – Confirm that installers are manufacturer-trained, background-checked, and drug-tested. Cutting corners on labor is the #1 reason new AC systems fail early.

Action Step: Call three companies and ask each if they perform a Manual J load calculation. If they don’t, cross them off your list immediately.

Step 2: Understanding Your Options

Types of Systems

• Straight A/C Units – Great for homes that only need cooling. Simple, reliable, and cost-effective.
• Heat Pumps – Provide both cooling and heating, which makes them a smart upgrade if you want year-round comfort.
• Gas Furnaces – Rare in Florida, but if you already have one, your contractor can advise if switching to a heat pump makes sense.

Compressor Technology

• Single Stage – Runs full blast every time. Cheapest but least efficient.
• Two Stage – Operates at low or high speeds, balancing comfort and energy savings.
• Variable Speed – Adjusts output continuously. Costs more upfront but saves the most on bills and keeps humidity under control.

Step 3: Proper AC Sizing

Never size your air conditioner based only on square footage. Upgrades like new insulation, windows, or roofing can dramatically change your cooling load.

• Undersized System – Struggles to cool, runs constantly, wears out early.
• Oversized System – Short-cycles, creates humidity problems, wastes energy.

At AC Authority, we always perform a Manual J load calculation before recommending a unit. This ensures you get the right size the first time.

Step 4: Cost to Replace an AC System

The average cost of a new air conditioner in Florida ranges from $5,500 to $12,000, depending on:

• System size and efficiency (SEER2 rating)
• Installation complexity (crawl space, attic, slab, etc.)
• Ductwork condition and repairs needed
• Add-ons like smart thermostats, zoning, or indoor air quality products

Red Flag: If a bid seems thousands lower than others, it usually means corners will be cut on ductwork, permits, or installation quality.

Step 5: Other Key Factors

• Ductwork & Insulation – Leaky ducts can waste 20–-% of your cool air. Make sure they’re inspected.
• Thermostats – Smart thermostats adapt to your schedule and save 10–20% on bills.
• Indoor Air Quality – UV lights, HEPA filters, and air purifiers improve health and comfort.
• Warranties – Look for strong parts and labor coverage. Many local companies only cover labor for 1 year.
• Financing – Options range from up to 18 months no interest to long-term plans up to 11 years, making it easier to fit a high-efficiency system into your budget.

Step 6: Efficiency Ratings (SEER2)

The higher the SEER2, the more efficient the unit. Federal minimums in Florida are now 14.3 SEER2, but top systems reach 20-24 SEER2.

• 14-16 SEER2 – Standard efficiency, lowest cost upfront.
• 17-20 SEER2 – Mid-range efficiency, balances cost and savings.
• 21+ SEER2 – Premium efficiency, best for homeowners staying in place long term

The average cost for a new AC unit is $5,000–$7,000, but AC installation in Port St Lucie can vary depending on the unit’s type, size, and condition of the ductwork. For an accurate estimate, it’s best to consult a licensed local HVAC professional.

Living in Port St. Lucie means enjoying sunny weather and warm temperatures nearly year-round in sunny Florida, but it also means relying heavily on air conditioning to stay comfortable. For homeowners considering a new AC unit, understanding the cost of installation is a critical step in planning your investment. However, as with all appliances, your AC unit will eventually wear out after around 10 – 15 years and require a replacement. If you’re a homeowner whose AC unit has just stopped blowing cold air, you’re likely researching the average cost of installing a new unit in Florida.

With so many factors influencing the price, from the type of system you choose to the condition of your home’s ductwork, knowing what to expect can help you make an informed decision and avoid unexpected expenses. Installing a new air conditioning system isn’t just about keeping your home coolit’s about improving energy efficiency, reducing utility bills, and increasing overall comfort.

Whether you’re replacing an old unit or installing a system in a newly built home, it’s important to weigh the upfront costs against the long-term benefits. In this guide, we’ll break down the average costs of AC installation in Port St. Lucie, the factors that influence pricing, and tips for saving money without compromising on quality.

Factors That Affect AC Installation Costs

Several factors influence the cost of AC installation in Port St. Lucie, and understanding these can help you plan your budget effectively. The type of air conditioning system you choose is one of the most significant determinants. Central air systems are often more expensive upfront due to their size and the need for ductwork, while ductless mini-split systems may offer a more affordable and versatile option for homes without existing ducts. Heat pumps, which can both heat and cool your home, are another option but often come with a higher initial price tag.

Another critical factor is the size of the unit, which must be appropriately matched to your home’s square footage and cooling needs. Larger units cost more, but an undersized system can struggle to cool your home effectively, leading to higher energy bills and reduced comfort. Efficiency ratings, measured by the SEER (Seasonal Energy Efficiency Ratio), also play a role in cost. Higher SEER ratings often mean higher upfront costs but result in long-term energy savings.

Additionally, the condition of your home’s ductwork, the need for electrical upgrades, labor costs, and local permit requirements can all add to the overall cost of installation. By considering these factors, you can better understand the range of costs and choose the right system for your home and budget.

Additional AC Installation Costs to Consider

When it comes to AC Installation Service in Port St. Lucie, there are additional costs that can arise beyond the price of just the unit itself.

One of the most common extra expenses is ductwork installation or repair. If your home’s existing ductwork is damaged, outdated, or non-existent, you may need to invest in new ducts or repairs, which can significantly increase the total cost. Similarly, homes with older electrical systems may require upgrades to support the energy demands of a modern air conditioning unit.

Labor costs are another key consideration, as installation complexity can vary based on your home’s layout and the type of system being installed. Homes with limited space or multi-story designs may require more time and effort, leading to higher labor charges. Additionally, permits and inspections are often required for AC installation to ensure compliance with local building codes in Port St. Lucie, and these fees can add to your overall costs.

Being aware of these potential expenses will help you avoid surprises and ensure you have a realistic budget for your new AC system if you’re in need of AC Installation or Replacement service in Port St. Lucie.

Average Cost Range for AC Installation Service in Port St. Lucie

The cost of AC installation in Port St. Lucie typically falls within the range of $3,300 to $5,900 for a standard new air conditioning unit. This range reflects the cost of common residential systems, including central air and ductless mini-split systems. However, the final price can vary depending on factors such as the type and size of the system, its energy efficiency rating, and any additional work required, like ductwork repairs or electrical upgrades.

For more complex installations or high-efficiency systems with advanced features, costs can exceed this range. For example, homes requiring entirely new ductwork or opting for premium brands with high SEER ratings may see prices closer to $8,000 or more. On the other hand, replacing an existing unit with minimal modifications required might fall on the lower end of the spectrum. To get a more accurate estimate for your home, it’s always best to consult with a licensed HVAC professional who can assess your specific needs and provide a detailed quote.

Cost-Saving Tips for AC Installation

Installing a new AC system can be a significant expense, but there are several ways to reduce costs while maintaining quality:

Take Advantage of Rebates and Tax Credits

• Look for energy provider or manufacturer rebates for installing energy-efficient systems, particularly those with high SEER ratings.
• Check for federal or state tax credits for energy-efficient home upgrades.

Schedule Installation During the Off-Season

• HVAC companies often offer discounts during cooler months when demand for AC services is lower.

Explore Financing Options

• Many HVAC contractors or manufacturers offer financing plans that let you spread the cost over time.

Ensure Proper Home Insulation

• Good insulation helps maximize AC efficiency, reducing energy waste and lowering utility bills.

Compare Quotes

• Get estimates from multiple contractors to find the best value without sacrificing quality.

Implementing these strategies can make your AC installation more affordable and help you save on long-term energy costs.

Choosing the Right HVAC Contractor in Port St. Lucie For AC Installations

Choosing the right HVAC contractor in Port St. Lucie is essential for a successful AC installation. Start by researching contractors with proper licensing, insurance, and experience in the local area. Look for companies with positive reviews and testimonials from past customers to ensure a solid reputation. Request detailed estimates from multiple contractors, including breakdowns of equipment, labor, and additional costs, to make an informed comparison.

Additionally, verify that the contractor offers warranties on both the installation and the equipment to protect your investment. A reliable HVAC contractor will also provide a thorough consultation, answering your questions and ensuring the system they recommend is tailored to your home’s specific needs.

The Long-Term Benefits of a Quality AC Installation

nvesting in a quality AC installation offers numerous long-term benefits that go beyond simply keeping your home cool. One of the most significant advantages is improved energy efficiency. A professionally installed air conditioning system operates more effectively, using less energy to cool your home. This translates to lower monthly utility bills and a reduced carbon footprint. Additionally, properly installed systems are less likely to develop issues like air leaks or uneven cooling, ensuring consistent performance and comfort throughout your home. Over time, the initial investment in quality installation pays off through energy savings and fewer repair costs.

Another key benefit is the extended lifespan of your AC unit. Poor installation can lead to unnecessary strain on the system, causing it to wear out faster. In contrast, a well-installed system operates within its intended parameters, reducing the risk of breakdowns and increasing its overall durability. This means fewer unexpected repairs and replacement costs down the road. Moreover, a quality installation often includes a comprehensive warranty, giving you peace of mind that your investment is protected. By choosing professional installation, you ensure your AC system delivers reliable performance, enhances indoor air quality, and maintains the comfort of your home for years to come.

Frequently Asked Questions About AC Installation Services in Port St. Lucie

What is the average cost of AC installation in Port St. Lucie

The average cost for a new AC unit in Port St. Lucie ranges between $3,300 and $7,000. However, this cost can vary based on factors such as the type of AC system (central air, ductless mini-split, or heat pump), the size of the unit, and the condition of your home’s ductwork. Additional costs may apply for electrical upgrades, permits, or removal of an old unit.

How do I know what size AC unit I need for my home?

The size of the AC unit you need depends on your home’s square footage, insulation, and cooling needs. HVAC professionals use a calculation method called the Manual J load calculation to determine the ideal size. Installing a unit that is too small will struggle to cool your home, while an oversized unit may waste energy and cycle on and off frequently.

How long does it take to install a new AC system?

The installation of a new AC system typically takes one to two days. This timeline can vary depending on the complexity of the installation, such as adding new ductwork or making electrical upgrades. Professional HVAC contractors will provide a timeline estimate based on your specific project.

Should I repair my old AC unit or replace it with a new one?

Deciding between repairing or replacing your AC unit depends on its age, efficiency, and the cost of repairs. If your unit is over 10–15 years old, requires frequent repairs, or has a low SEER rating, replacement may be more cost-effective in the long run. A new, energy-efficient unit can reduce energy bills and improve overall performance.

How can I find a reliable HVAC contractor in Port St. Lucie?

To find a reliable HVAC contractor in Port St. Lucie, look for companies with proper licensing and insurance, positive customer reviews, and a track record of serving the Port St. Lucie area.

Air conditioning is an incredibly important appliance for any home, providing cool or hot air during any time of the year. So when your AC unit is not working correctly it can be concerning, especially when you are depending on it to cool down your home during the summer months. If your air is not cooling properly there are certain things that could be failing. We put together this guide so you can know when it is a fixable issue or you need to call the specialists at AC Authority!

1. Mechanical Failures or Faults

There is a lot of technology and mechanical marvel that goes into making an AC system operate correctly. Several working parts take air, cool or heat it, disperse it through the system and expel hot air outside of your home. Here are the basic components of most air conditioning units:

• Fan or Heat Pump
• Evaporator coil (for cooling the air)
• Compressor (electric pump)
• Condenser Coil (transfers heat)
• Expansion Valve

In addition, there may be a duct system utilized for directing the air throughout your home if you have a central AC unit. With all of these parts there is often an issue on the mechanical level. If your fan is not operating correctly the main unit cannot disperse heat correctly. Or, if the compressor is faulty, the refrigerant can’t circulate between the inside and outside units.  

The best way to fix mechanical issues is to get regular maintenance and seek professional advice!

2. Dirty or Clogged Air Filter

Every air conditioning unit has a filter that the air being drawn through the system passes. When this filter becomes clogged with dirt, dandruff, pet hair or other large particulates it can affect the entire system. In rare cases, if the air flow is extremely blocked, the cool air can cycle back through into the evaporator coil, which in turn causes it to freeze. 

Overall, a dirty air filter can hinder the air flow and reduce efficiency of the entire system, making it much harder to cool your house. For Central conditioning units you should be changing your filter once a month. You can make things easier on yourself by having a Smart Thermometer, as they can alert you when a filter needs to get changed.

2. Low Refrigerant

Refrigerant is the magic elixir that makes an AC unit cool air. When cold liquid refrigerant evaporates on the evaporator coil, it turns into gas. The much hotter gas is then pumped outside into your system’s condenser, where it transfers the heat to the outside air and reverts into a liquid again and the cycle continues. Already you can see how low refrigerant is a huge issue. 

Manufacturer’s specifications can tell you what the levels would be at, but this is definitely an issue that should be handled by a professional. Here are a few reasons why: 

• It is likely there is a leak, so adding more would just be pointless. A professional can pinpoint the leak and fix it to keep refrigerant from spilling out. 
• Refrigerants can be toxic if handled incorrectly. 
• Your system may use a special kind of refrigerant rather than the standard freon most systems use. 

AC Authority knows the best methods for repairing coolant leak and can get your issues sorted out, ASAP!

4. The Outdoor Unit Is Overheating

This is a more common problem if your AC system has a secondary unit outside of your home and may have been installed incorrectly. These units need a proper amount of space from the building as well as any shrubs or bushes in order to cycle air properly. While cutting some bushes away is an easy problem to solve, if your unit had been installed on the side of the house that gets the most sun, there is little that can be done. 

Pro tip: When we install an AC unit, we always take into consideration the placement of your outside equipment. That’s part of the reason AC Authority is the best!

Typically, you want to make sure there is at least 2-3 feet between the unit and any plants, fences or trees. But when it comes to the top of the unit, which expels more heat, make sure there is nothing within 5 feet of it!

5. The Unit Is Unfit For The Space

Our final and perhaps biggest culprit of an insufficiently cooled home is that the system is not fit to cool the space. Some air conditioners are perfect for a single room while others are better for entire houses. If your home isn’t being cooled then you may have the wrong system!

Typically smaller homes or single rooms can be cooled by:

• Portable AC units
• Mini-split Ductless units
• Window Mounted units

Whereas, large homes need things like:

• Central air conditioning
• Geothermal air conditioning

This is also the time to call a professional, but it’s better to do it when you are shopping around. They can provide general guidance and recommendations that you may not have thought of!\

Key Takeaways: 

Making sure you stay cool during the hot months is easy as long as you know what could stand in the way of your air conditioning system. Faulty parts, dusty filters, refrigerant leaks and improper placement of external units can all contribute to your AC not cooling correctly. IT can also save you time, money and a headache if you consult with AC Authority when you are ready to purchase a new unit!

TLDR: There are several types of Air Conditioning units available on the market. If you compare cost, energy consumption, size and efficiency, you will find that some are better than others! We recommend contacting us before making a purchase to ensure you get the right unit for your specific needs. Ultimately, regardless of what AC unit you have, AC Authority can repair any system and keep it in pristine condition. 

When looking at the Air Conditioning market it is fairly easy to get overwhelmed. The sheer amount of systems available means you have a plethora of options to choose from and not all of them are good for every environment. What kind of system you need can change depending on:

• Your budget
• How energy efficient the system needs to be
• The amount of space you have for your system
• The amount of cooling power you need

As the premier experts in all things Air Conditioning, we know all systems back and forth, front to back! So we provided this guide to help you sort through all your options. Of course, the best thing to do would be to get a recommendation from the experts but this can get you started on your information gathering journey. 

Why Air Conditioning Is Important

Air Conditioning, or AC units are one of the most common appliances in American homes you can find. They not only keep your home cool, but keep the air quality good and can help reduce energy costs during certain times of the year. 

The better your system is at using energy the more money you can save. While keeping your unit well maintained influences how efficiently it works, it is important to know the capabilities upfront as well. 

There are 7 main types of air conditioning systems we will cover, each with their own pros and cons! They are: 

1. Central Air Conditioner
2. Ductless Mini-Split
3. Window Air Conditioner
4. Portable Air Conditioner
5. Floor Mounted AC
6. Hybrid / Dual Fuel Air Conditioner
7. Geothermal Air Conditioner

Each one has specifications that may or may not be suitable for your home! Let’s dive in.

The 7 Main Types Of Air Conditioner Systems

Central Air Conditioning

We are starting off with the system we recommend for most homes and larger buildings. Suited for cooling multiple rooms, central air conditioning utilizes a split system, meaning the unit outside holds the condenser and compressor while what is actually in your home is the evaporator coils & air handler. It is worth noting that central air utilizes refrigerant to remove heat from the outdoor air while pushing the cooled air through ducts. 

Pro tip: Most, if not all units can use programmable thermostats, making keeping your home a consistent temperature easy. 

Advantages of Central AC:

• The use of ductwork to disperse the cool air maintains a consistent and regulated environment, even through large structures. 
• Humidity is reduced thanks to the constant circulation of cool air. 

Disadvantages of Central AC:

• This system uses a lot of power and can be the most expensive option depending on the size of the unit. 
• Due to having a separate duct system to disperse the cool air you also have to maintain the ducts in order to keep consistent airflow.

Ductless Mini-Split:

Up next we have the much smaller but much more efficient ductless system. While it only cools small spaces (a room or two at best) it combines all of the parts that make up an AC unit into one compact machine. Mounted on a wall and equipped with blowers, the refrigerant circulates depending on which setting is being used. The common recommendation is to have one unit per room, though you can see how that can get expensive quickly.

Mini-splits usually have a remote controller or an app that you can use from your phone making them a somewhat more convenient option as well.

Advantages of Ductless Mini-Splits:

• Easy to install and due to being more compact can be put almost anywhere.
• Can control multiple rooms’ temperature independently of each other.

Disadvantages of Ductless Mini-Splits:

• Unable to cool large homes unless multiple units are installed.
• Obviously visible and must be mounted on an empty portion of the wall.

Window AC:

These units come in several sizes that can cool either a single room or a small home with decent efficiency. Many american homes utilize window AC units, since all of the components are kept in one place the filter is easy to clean out and the mount to the window keeps any hot air from the system directed outside of your home. 

Advantages of Window AC:

• Less costly to maintain and cheaper to install.
• Easier to install and maintain.
• Utilizes the space around a window rather than a wall or the floor.

Disadvantages of Window AC:

• Both noisy and very obviously in plain view.
• Blocks a window in your home but must also be near an outlet.
• Unable to be mounted on odd-shaped windows

Portable Air Conditioner:

Next up is a unit that has many of the same design specifications as a window AC, minus needing to be mounted in a window. The components are still in a single unit, it has a removable, cleanable filter and requires a free power outlet. Coming in multiple sizes you can cool anything from small areas in your home to full sized rooms. 

Portable AC units can also either have single-hose systems or double-hose systems. They both expel hot air back outside but the dual-hose system also pulls air from outside in order to be cooled.

Advantages of Portable AC:

• Simple to set up.
• Can be moved since they are not “installed” like other units.
• Effective for spot cooling without breaking the bank.
• Can be stored quickly and without needing a lot of space.

Disadvantages of Portable AC:

• Noisy during operation.
• Unable to cool large rooms well.
• The house still needs to be near a window while in use.

Floor Mounted AC:

These air conditioners were designed to be as convenient as mini-split systems but don’t need to be mounted high up on a wall. It is also ideal for tilted or glass walls, with the outer portion of the unit able to be installed with little preparation and no ductwork. 

The filters used in floor mounted AC units are  easy to check and since the unit sits at the same height as you they very effectively cool and heat rooms because the fans are blowing across the space evenly. 

Advantages of Floor Mounted AC:

• The most accessible system available makes it the best choice for disabled or elderly people. 
• Easy to install and takes up very little space.

Disadvantages of Floor Mounted AC:

• Needs the area in front of it to be clear or the airflow is interrupted. 
• Not great at cooling large rooms since the airflow is so localized.

Geothermal Air Conditioning System:

This system is one of the newer solutions to air conditioning. It uses the ground beneath your home as insulation, while pumping water through the area that gets cooled or warmed respectively with geothermal technology.

The system takes extensive work to set up.

Advantages of Geothermal AC:

• High energy efficiency.
• The lifespan of this system is substantially longer than any other.

Disadvantages of Geothermal AC:

• Can only be installed in specific areas.
• The cost of installing this system is much higher than other options.

Hybrid/Dual Fuel Air Conditioner:

Last, but certainly not least is the hybrid system. Utilizing a gas furnace in combination with an electric heat pump, this option for air conditioning has decent performance and is fairly cost effective. The unit can switch between either electricity or gas-powered conditioning based on the outdoor temperature, the parameters of which are completely customizable. 

If the inside of your home is hot the heat pump pushes the air outside while during the winter months the process is reversed. If it becomes too cold the furnace turns on in order to maintain the temperature instead.

Advantages of Hybrid/Dual AC:

• Has both efficiency and low-cost operation.
• Reduces your carbon foot-print.

Disadvantages of Hybrid/Dual AC:

• Can be expensive to install.
• You have to maintain both the furnace and the heat-pump in order for it to function properly.

Understanding Different Air Conditioning System Types

All of the options presented can be a good choice depending on the size of the space being cooled or heated, the amount of money you have to spend and the amount of energy available. This article gives the basic information required to assess which air conditioning system you need, but the process of shopping around can still be a challenge. As the expert AC installation and repair company, AC Authority can always help guide you to the best choice for your AC systems.

Air Conditioning systems are the most common electrical appliance in the United States. As such, many people have had to deal with their units becoming faulty and not working properly over time. Maintenance and repair can help mitigate the frequency of these problems but sometimes it’s better to replace the system. Constant repairs cost money and in the end it may be a better investment to buy a new AC unit altogether. But then the big question becomes how do you know when it’s time to replace versus repair? We compiled a list of details to look for so you know when it’s time to start shopping around! 

Your Unit Is Blowing Hot Air

First off is perhaps the most obvious sign that you need to replace your air conditioning system. If your unit is blowing warm air it is likely that either there is an issue with the condenser or perhaps more seriously a coolant leak. Coolant, or freon, is the chemical responsible for cooling the hot air that is pulled into the system while the condenser is what actually pulls the hot air in and out. 

Whether it is the condenser or refrigerant that is the problem, the inability to cool makes your AC unit basically useless. Repairs for these issues can also be costly, so it’s better to have the professionals come out and help you decide if it would be cheaper in the long term to replace. AC Authority gives free quotes upon inspection so you can always have an idea of what the best solution is. 

Moisture Is Building Up 

This one can be a more subtle sign that is easy to miss. AC units, especially central cooling systems, are excellent at removing moisture from your home. This contributes to making the overall environment in your home much more comfortable! But if you begin to notice that the air is unnaturally humid despite your AC running, that could mean a few things are malfunctioning:

• The airflow is obstructed, either due to a dirty filter or clogged duct work.
• The condenser is malfunctioning.
• There is a coolant leak
• Water build-up in the system is causing issues

To truly know if this is a quick fix that can prolong the life of your system you would need to have an expert come out to inspect what’s causing the issue.

A Strange Smell Is Present

More obvious, you may notice strange smells inside your home and around the unit. Some examples of smells to keep an eye out for are: 

• Moldy or musty smells
• Burning or electrical fire

These smells are a sure sign of a few problems, like dirty air filters or mold growth in either the drip pans or the evaporator coil. If there is a leak causing mold to grow not only is it a huge health hazard but is a sign of a larger problem. 

Loud Noises

Another more obvious sign is if there are strange noises from the unit. Loud knocking or whirring, for example. While most loud noises are caused by clogging in the system and can be easily fixed by regular maintenance, if the system is more than a few decades old it may just be time to replace everything. AC Authority offers a unique solution when it comes to maintenance! Our 24/7 Maintenance plans make sure you are covered, no matter the time of day. 

The System Needs Constant Repairs

Speaking of maintenance plans, this is a huge sign that it is time to get a new unit. If your system is breaking down on a monthly basis then you definitely need to look at shopping around. While regular maintenance is important and necessary, if you are spending an equivalent amount of money on maintenance as you would on making a down payment for a new system then skip the repairs and buy a new unit.

How To Choose A New AC Unit

If this article has pointed you towards purchasing a new air conditioning system then the next question is how do you begin shopping for one? This is a complicated question that could require an entirely different article to cover. However, AC Authority can help make your purchase an educated one by providing you with years of expertise and a comprehensive recommendation. We take into account your home’s size, the energy ratings of the unit and the floor plan that the system would need to be installed into. 

We also offer payment plans for AC units with expert installation and affordable maintenance options!

Key Takeaways

Knowing when it’s time to get a new system will help you save money in the long run. Specifically, paying attention to whether your unit is blowing cool air, looking for excess moisture or strange noises as well as smells, and examining how often you have to get it repaired. AC Authority is hear to guide you through these decisions no matter what and make sure that you are saving money!
