Florida Licensing and Efficiency Rules
Florida is in the DOE's Southeast region, where new split central air conditioners need at least 14.3 SEER2 (13.8 SEER2 for systems of 45,000 BTU/h and up). Most repairs don't need a permit. Anyone who opens the refrigerant circuit does need EPA Section 608 certification, and in Florida the company should carry a state license or registration. Ask for both.
Before You Hire
- Book maintenance twice a year, once before summer and once before winter.
- Keep two feet clear around the outdoor unit, including snow.
- Many heat pumps carry a 10-year parts warranty if they were registered. Find out whether yours was.

Heat Pump Repair Questions from Largo Homeowners
What does heat pump repair cost in Largo?
Most bills land between $190 and $940, including the service call. A typical visit is about $600. Night and weekend calls cost more.
Why is my heat pump blowing cold air?
For a few minutes during a defrost cycle, that's normal. If it keeps going, the usual causes are a stuck reversing valve, low refrigerant or a thermostat set to the wrong mode.
Is it normal for a heat pump to freeze?
A thin layer of frost in winter is normal, and the defrost cycle should clear it. Heavy ice that stays usually means a defrost control or airflow problem.
