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 |

| Nights at or below 32°F | 0 |
| Days above 90°F | 30 |

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.
