Miami Weather and HVAC Load
In a normal year, Miami racks up 138 heating and 4,186 cooling degree days (NOAA 1991-2020 normals). Cooling carries most of the load, which is why compressors and condenser fan motors wear out faster here than in northern cities. Freezing nights are rare here, but a normal year brings 30 days over 90°F.
| Heating degree days / year | 138 |
|---|---|
| Cooling degree days / year | 4,186 |
| Nights at or below 32°F | 0 |
| Days above 90°F | 30 |
| Average low / high | 70.9°F / 81.2°F |
Miami Housing Stock
Census figures put the median build year in Miami at 1978, so a typical house here has about 48 years on it. A lot of these homes are on their second or third system by now. The ductwork is usually original, and leaky joints are common. About 58,000 households here own their home, 30.7% of the occupied total. Homes here have a median value of $475,200 and households a median income of $59,390. Those two numbers drive the labor adjustment in our estimate.
NOAA storm reports for Miami-Dade County show 12 hail days and 29 days with damaging thunderstorm winds over the six years from 2020 to 2025. The largest hail reported was 1.75 inches across. Hail flattens the thin aluminum fins on condenser coils and cuts airflow. After a big storm, take a look at the outdoor unit; homeowners insurance often covers the damage. Miami-Dade County also had 6 tornado days in that period.

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
- Light frost on the outdoor unit in winter is normal. A solid block of ice is not.
- Many heat pumps carry a 10-year parts warranty if they were registered. Find out whether yours was.
- Book maintenance twice a year, once before summer and once before winter.

Heat Pump Repair Questions from Miami Homeowners
What does heat pump repair cost in Miami?
Most bills land between $220 and $1,070, including the service call. A typical visit is about $690. Night and weekend calls cost more.
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.
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.
