WHAT SHOULD YOU LOOK FOR IN AN AC UNIT IN FLORIDA?

Florida’s average summer highs in the 90s and high humidity levels (70% and more) make cooling systems work harder and run for longer than in most parts of the country.

The additional salt in the air near coastal areas poses additional risks for AC units.

Central AC dominates in Florida, with over 90% of homes employing a central cooling system. Around 11% of homes have individual air conditioning units installed.

Regardless of the type of AC you’re considering, certain characteristics are key for all the best Florida air conditioning units…

ENERGY EFFICIENCY

SEER/SEER2 ratings are a measure of the energy efficiency of AC units.

In Florida, the minimum SEER2 rating for new AC installations is 14.3 for split-system air conditioners under 45,000 BTU/h and 13.8 SEER2 for larger units, as per the DOE.

Homeowners should look for a SEER 2 rating of 15 or higher for greater energy efficiency and savings on monthly bills.

Two-stage AC units or those with variable-speed compressors deliver the best results.

CORRECT SIZING

Size your AC unit correctly, because a unit that is too large or too small can cause inefficiency and many cooling/indoor air quality issues.

To properly size your AC unit, a Manual J load calculation may be required from an HVAC professional. This will accurately assess your home’s cooling requirements.

The HVAC pro can recommend a tonnage (and BTU rating) for your unit, based on this calculation.

HUMIDITY CONTROL

The higher the humidity, the hotter it feels. So, make sure the AC unit you install can effectively reduce humidity inside your home.

All AC units remove moisture from the air as part of the cooling process, but with Florida’s humidity levels so high, is your new unit up to the job?

Variable-speed and two-stage models generally provide enhanced humidity control and you can also try pairing your AC with a dehumidifier.

DURABILITY AND CORROSION RESISTANCE

Coastal homes need AC units with powerful corrosion resistance, especially for essential parts like the coils and compressor, as well as the main cabinets.

Special coatings and the use of aluminum can protect from rust, increasing the unit’s lifespan.

SMART THERMOSTAT COMPATIBILITY

The best AC units for Florida are also compatible with programmable and smart thermostats.

When used properly, these important devices help homeowners control temperatures and humidity for consistent home comfort, while also reducing energy usage and monthly bills.

LONGEVITY

You want your AC to last as long as possible but the average life of an AC unit in Florida is lower than in most of the country.

This is mainly because AC units work harder here. So, instead of 15-20 years for a well-maintained AC, a typical AC unit in Florida lasts 8-15 years.

WARRANTY COVERAGE

Air conditioner manufacturer warranties in Florida typically last 5-12 years on parts and compressors.

Base coverage is often five years, with extended options up to 10-12 years available. Most of the leading brands, such as Carrier, Rheem, Trane, and American Standard, offer competitive warranties.

BEST CENTRAL AC UNITS FOR FLORIDA HOMES

With regular AC tune-ups, modern central AC units from any leading brand can offer:

Excellent reliability.
Longevity.
Energy efficiency.
Cooling performance.
Good indoor air quality/humidity control.

Central air conditioning is ideal for larger homes with multiple rooms used frequently by multiple occupants.

Central air conditioners are split systems that use an outdoor compressor and an indoor air handler to circulate cool air through the home’s ductwork. This provides consistent, whole-home cooling without having to keep turning AC units on and off in individual rooms.

Most modern units are compatible with smart thermostats for extra control and energy efficiency.

TOP CHOICE: A variable-speed AC unit

Variable-speed units use a compressor that continuously adjusts its motor speed to match the home’s exact cooling demands. They run for longer at lower speeds instead of cycling fully on/off.

These units offer the following homeowner benefits:

Up to 30-40% higher energy efficiency by avoiding startup surges and running precisely according to cooling needs.
Enhanced humidity control through extended low-speed operation for better dehumidification.
Quieter performance and even temperatures without hot/cold spots.
Longer lifespan due to reduced wear from fewer cycles.

The downside? Variable-speed AC units are more expensive than standard or two-stage units.

NEXT BEST: A two-stage AC unit

Two-stage AC units operate at two fixed output levels—a low (60-70%) level for mild conditions and a high (100%) level for peak demand—switching between them based on signals from the thermostat.

Two-stage units offer the following homeowner benefits:

Better efficiency (20-30% savings) compared with single-stage units due to low-mode usage most of the time.
Improved comfort with fewer temperature swings and better humidity removal on the low stage than standard AC units.
Quieter and less wear and tear than single-stage units.
Lower costs than the highest-efficiency variable-speed units in Florida (though they are more expensive than single-stage units.

DUCTLESS MINI-SPLIT SYSTEMS: BEST FOR FLORIDA HOMES WITHOUT DUCTING

If your home does not have ductwork installed, you’ll need to incur the expense and inconvenience of having it installed or opt for a solution other than central AC.

Ductless mini-split AC systems are common choices in these situations. They are like central AC units, with an outside compressor unit and an indoor air handler, but designed to cool individual rooms rather than the whole home.

Ductless mini-split systems are ideal for:

Energy-efficient cooling without the need for ductwork.
Zoned cooling for personalized comfort.
Adding HVAC to garage conversions and sunrooms.
Easy installation with minimal disruption.

The downside? If you need multiple units, the upfront costs are higher and the indoor unit is more visible than central AC, which is often in the basement.

HEAT PUMPS FOR FLORIDA HOMES: BEST IF YOU NEED HEATING & COOLING IN ONE SYSTEM

Air-source heat pumps are ideal solutions for homes without furnaces or other heating solutions and looking for cooling and heating from a single unit.

Winters are much milder in Florida than most of the country (temperatures are rarely below 40°F) but homes still require some form of heating for a few months of the year. Heat pumps fit the bill for many homeowners.

Heat pumps work by transferring heat into or out of the home, depending on the season. The best units use variable-speed or two-stage heat pump technology to offer:

Precise and reliable comfort.
Energy-efficiency (high SEER2 and HSPF2 ratings for units).
Excellent humidity control.

Ground-source/geothermal heat pumps use the stable temperatures underground (rather than air) to heat and cool your home. Installation is complex and expensive but the pay-offs in heating and cooling stability and low operating costs are worth it for new homes and homeowners looking for long-term solutions.

The downside? Heat pumps are more expensive than air conditioning units, though only one unit is required rather than separate heating and cooling solutions.

SIGNS IT’S TIME TO REPLACE YOUR AC

Some typical signs that it’s time to replace your air conditioner in Florida include:

An ageing system that was installed 10-15 years ago.
Frequent repairs are required.
Regular problems cooling the home adequately despite annual maintenance.
Uneven cooling in the home.
Unexplained higher energy bills.
