Why is my AC running but not cooling my house in Florida?
When your AC runs nonstop but the house never cools, the usual causes in Central Florida are a dirty coil, low refrigerant, a failing capacitor, or a system that is simply undersized for the July heat load.

Why does my AC freeze up in humid weather?
A frozen AC in Florida almost always comes down to restricted airflow or low refrigerant. Both drop the coil below freezing, and the state's humidity turns that cold coil into a block of ice fast.

Why is my AC blowing warm air in the Florida heat?
Warm air from the vents usually points to a tripped breaker on the outdoor unit, a thermostat set to the wrong mode, a frozen coil, or a refrigerant problem, in roughly that order of how often we find them.

Is it normal for my AC to run constantly in the Florida summer?
On the hottest Central Florida afternoons a healthy AC will run nearly nonstop, and that alone is normal. It stops being normal when it runs all day, never satisfies the thermostat, and the house still climbs.

Why does my AC smell musty or moldy when it runs?
A musty or moldy smell from the vents usually means moisture is sitting somewhere it should not, on a dirty evaporator coil, in a clogged drain line, or in damp ductwork, which Florida humidity turns into mold territory fast.

How often should I service my AC unit in Florida's climate?
In Central Florida the right cadence is twice a year, not once. Cooling runs most of the year here, so a spring tune-up before the heat and a fall check keep the system efficient and catch failures early.

Is an AC maintenance plan worth it in Florida?
For most Central Florida homeowners a maintenance plan pays for itself, because the long cooling season makes twice-a-year service worthwhile and the plan locks in that cadence, priority service, and protection for your warranty and compressor.

What are the signs my heat pump is failing?
Watch for a heat pump that short cycles, blows lukewarm air in heat mode, runs constantly, gets loud or shaky, spikes your power bill, or ices over and never defrosts. In Central Florida the same unit handles both cooling and heat, so failure shows up year round.

What causes short cycling in a heat pump?
Short cycling, when the unit turns on and off every few minutes, usually comes from restricted airflow, low refrigerant, a failing capacitor or control, a bad thermostat location, or a system oversized for the home. Each one wears the compressor fast.

What SEER2 rating do I need for a new AC in Florida?
Florida sits in the Southeast region, where federal rules set a minimum of 14.3 SEER2 for a new split-system AC. Many homeowners here step up to 15.2 to 17+ SEER2 because the long cooling season makes the efficiency pay back faster.

How long does an AC unit last in Florida heat?
In Central Florida a central AC or heat pump typically lasts 10 to 15 years, shorter than the national average, because the long, hot, salty, humid cooling season runs the equipment far more hours than in most of the country.

Ductless mini-split vs central AC: which is better for a Florida home?
For a whole existing Florida home with good ducts, central AC is usually the better value. For an addition, garage conversion, sunroom, or a home with no ductwork, a ductless mini-split is often the smarter, more efficient choice.

How much does AC installation or replacement cost in Central Florida?
A new central AC or heat pump in Central Florida generally runs from the mid four figures for a straightforward same-size replacement up into the five figures for a larger home, higher efficiency, or added ductwork. The only accurate number comes from an on-site load calculation.

How much does AC repair cost in Florida in 2026?
Most AC repairs in Central Florida land in the low-to-mid hundreds, a capacitor or contactor on the low end, refrigerant or a motor higher, and a compressor or coil into four figures. A flat diagnostic fee and an up-front quote are what tell you which one you are looking at.

What's included in emergency HVAC service and what does it cost?
Emergency HVAC service is same-day, after-hours dispatch when your system quits and you cannot wait, nights, weekends, and holidays. It usually carries a higher call-out rate than a scheduled visit, but a good company still diagnoses and quotes the repair before doing the work.
