Westchester Weather and HVAC Load
In a normal year, Westchester racks up 141 heating and 4,430 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 93 days over 90°F. On the cooling side, a 2,000 sq ft house here usually needs around 4 tons. A tight, well-insulated house may get by with half a ton less.

| Nights at or below 32°F | 0 |

Westchester Housing Stock
The median Westchester home dates to 1971, according to the Census ACS. That makes the typical house about 55 years old. A lot of these homes are on their second or third system by now. The ductwork is usually original, and leaky joints are common. Owners live in 68.1% of occupied homes, roughly 12,000 households. With a median household income of $75,905 and a median home value of $473,300, local labor rates come out near the national middle in our model.
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. In Westchester, 23% of residents are 65 or older. For older adults, a house with no heat in January or no AC during a heat wave is a medical risk. Mention it when you call, since many companies put those calls first.

Florida Permits, Efficiency Rules and Rebates
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). Equipment replacements in Westchester generally need a mechanical permit, and a reputable contractor will pull it for you. Ask for their Florida license or registration number and a certificate of insurance with the quote. The federal 25C tax credit ended for equipment installed after December 31, 2025, so incentives now come mostly from utilities and state programs. Check your electric and gas utility's rebate page before you pick equipment.
Before You Hire
- Rinse the indoor filters once a month during heavy use.
- Most mini-splits qualify for utility heat pump rebates, so check before you buy.
- If winter nights regularly drop below 10°F, pay for a cold-climate model.
