U.S. Census Bureau, ACS 5-Year Estimates · public county data, not a national estimate
An AC that runs but doesn't cool is almost always an airflow problem or a refrigerant problem — and the airflow causes are far more common and far cheaper.
Handle it soon — these get more expensive with time. If the breaker for the AC trips more than once, stop resetting it — repeated trips mean an electrical fault or a seized compressor, and forcing it risks damage or fire.
Common causes:
• A clogged filter or dirt-caked coil choking airflow until the system can't move heat
• A refrigerant leak — the charge doesn't get used up, so low refrigerant always means a leak somewhere
• A weakening capacitor letting the outdoor unit limp instead of run at full strength
• Condenser coils coated in dirt or coastal salt film, so heat has nowhere to go
• A tech who tops off refrigerant without searching for the leak — you'll be paying for the same gas again next season
• A full replacement quote over the phone before anyone has looked at the system
• No state license number on the estimate — Florida licenses air-conditioning work at the state level
• Pressure to decide on a new system the same afternoon the old one is diagnosed
Why is my AC running but blowing warm air?
Check the filter first — a badly clogged filter alone can do it. If the filter is clean and the outdoor unit is running, the likely culprits are a refrigerant leak or a coil problem, both of which need a licensed tech with gauges to confirm.
Is adding refrigerant a real fix?
Only if the leak that let it out gets found and repaired. Refrigerant circulates in a sealed loop and never gets consumed — a system that needs regular top-offs is leaking, and each recharge without a leak repair is money evaporating.
AC repair (capacitor / fan / minor): $150–$1,200 (typical ~$400)
A compressor is the expensive failure — often $1,500–3,000+.
Curated Florida 2026 estimate — installed cost for a typical FL single-family home, not a bid.
Florida licenses this trade at the STATE level (DBPR / CILB (Class A/B)). Hiring unlicensed for this work is illegal for the contractor — and risky for you: no permit rights, no insurance backing, no recourse.
Work like this often requires a county permit — a legitimate pro pulls it, not you.
Basis: FL Stat. 489 (DBPR state licensing).
