Why is my AC not cooling my Orlando home?

The most common causes in Florida are low refrigerant from a leak, a dirty condenser coil, a failed capacitor, a clogged filter restricting airflow, or a failing compressor. In Orlando's heat, a cooling problem becomes uncomfortable within an hour. Same-day diagnostics. Call (407) 225-8903.

Why does my AC freeze up in Florida?

Frozen evaporator coils are almost always restricted airflow from a dirty filter or blocked return vent, or low refrigerant. Turn the system off. Run the fan only to thaw it. Then call us. Running a frozen system damages the compressor, the most expensive component in the unit.

Why is my AC running constantly but not cooling?

In Orlando's heat, this usually means a refrigerant leak, a dirty or failing condenser, or an undersized system. If it previously kept up and now can't, refrigerant loss or coil fouling is the likely cause. If it never kept up, the system may have been undersized from the start.

What do strange AC noises mean?

Banging or clanking means a loose or broken internal component. Squealing means a belt or bearing issue. Grinding is the motor. Clicking that won't stop is usually a failing relay or capacitor. All of these get worse the longer the system runs.

Should I repair or replace my AC in Orlando?

Start with the 50% rule. If the repair costs more than 50% of a new system, replacement is usually the better investment. Factor in age, Florida-specific lifespan of 10 to 15 years, efficiency ratings, and repair history. Our non-commission technicians run this math with you honestly. We don't benefit from pushing you either direction.

How often should I service my AC in Orlando?

Twice per year. March or April before peak cooling season and October or November after it. Florida ACs run 12 months per year and accumulate 3 to 4 times the annual run hours of an AC in the northern US. Once-a-year maintenance isn't enough for that wear rate.

How often should I change my air filter in Orlando?

Every 30 days for standard 1-inch filters in a Florida home. Year-round operation and Orlando's humidity load filters faster than national averages suggest. A clogged filter is the single most preventable cause of AC problems.

What does an AC tune-up include?

Thermostat calibration, evaporator and condenser coil cleaning, condensate drain flush, refrigerant level check, capacitor and contactor testing, electrical connection tightening, blower inspection, and a full performance test. You get a written report with everything we found.

What is the HVAC Experts ProPlan?

Our preventive maintenance membership for Orlando homeowners. Two tune-ups per year, priority scheduling, no overtime charges, and discounts on repairs. Most members break even on their first discounted service call. Everything after that is savings.

How long does an AC system last in Florida?

10 to 15 years on average, shorter than the national estimate of 15 to 20 years because of year-round operation. Regular bi-annual maintenance is the biggest factor in reaching the top end of that range.

What SEER2 rating do I need in Orlando?

Florida's current minimum for new installations is 15 SEER2. For most Orlando homeowners, 16 to 18 SEER2 is the best value-to-efficiency ratio. The payback from energy savings versus the upgrade cost typically runs 4 to 7 years. High-efficiency models at 20-plus SEER2 make the most sense for homes with high solar gain or large cooling loads.

Is a heat pump better than a regular AC for my Orlando home?

For most Orlando homes, yes. One system for heating and cooling, 2 to 3 times the efficiency of electric resistance heat in winter, and eligible for up to $2,000 in IRA federal tax credits. Florida's mild winters mean heat pumps stay in their optimal range year-round, unlike northern markets where cold weather limits performance.

What rebates are available for new AC installation in Orlando?

Federal: IRA 25C credit covers up to $2,000 for qualifying heat pump systems through 2032. Utility: FPL On Call, Duke Energy Smart $aver, and OUC all offer rebates for qualifying high-efficiency systems. We identify all applicable rebates at your free installation quote and handle the utility paperwork.

What does it mean that your technicians don't work on commission?

They earn a flat salary. The same amount regardless of what they find or what they sell. There is no financial incentive to recommend the more expensive repair, the larger system, or the unnecessary add-on. You get what your system actually needs.

How do I know if an HVAC contractor is being honest with me?

Ask if their technicians work on commission. That's the fastest diagnostic. Other signs of an honest contractor: they provide an itemized written quote before starting any work, they explain findings in plain language, and they're willing to walk through repair-vs-replace math without pressure.

Do you offer free second opinions?

Yes. If another company quoted you for a repair over $1,500 or a full system replacement, bring the itemized quote and your second opinion is free — the on-site diagnostic and the written report cost nothing. We'll send a non-commission technician to independently assess your system. For standard service calls outside the second-opinion offer, a $49 diagnostic applies, credited toward any repair you approve.

How does Orlando's humidity affect my home's air quality?

Orlando averages 74% relative humidity year-round. Inside your home without active management, that humidity creates conditions for mold growth in ducts and air handlers, dust mite proliferation above 50% humidity, and amplified allergen circulation. A whole-home dehumidifier maintaining 45 to 55% indoor humidity addresses all three.

Why does my house smell musty when the AC turns on?

Mold or mildew on the evaporator coil, inside the air handler cabinet, or in the condensate drain pan. Common in Florida. UV germicidal lights and annual coil cleaning address the source. Air fresheners don't.

Why is my FPL or Duke Energy bill so high in summer?

Usually one of these: a dirty or degraded system working harder than it should, refrigerant loss reducing efficiency, a system approaching end of life, or an older low-SEER system that's inefficient by modern standards. A tune-up or efficiency assessment identifies which factor is most significant in your home.

Do I need a dehumidifier on top of my AC in Orlando?

Sometimes. AC removes humidity as a byproduct of cooling, but in spring and fall when temperatures are mild, the AC runs less and humidity rises inside even when the temperature is comfortable. Whole-home dehumidifiers maintain 45 to 55% indoor humidity year-round. Worth considering if mold, dust mites, or musty smells are recurring issues.

Plain answers

HVAC questions, answered for Orlando.

Florida AC is not the same as AC everywhere else. Year-round cooling, 74% average humidity, heat pump dominance, SEER2 regulations. These answers are specific to Central Florida and updated for 2026.
