Boca Raton Weather and HVAC Load
In a normal year, Boca Raton racks up 133 heating and 4,607 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 59 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 |

Boca Raton Housing Stock
The median Boca Raton home dates to 1983, according to the Census ACS. That makes the typical house about 43 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 65.8% of occupied homes, roughly 27,000 households. With a median household income of $102,722 and a median home value of $660,100, local labor rates come out above the national middle in our model.
Between 2020 and 2025, NOAA's Storm Events Database logged 21 hail days and 28 days with damaging thunderstorm winds in Palm Beach County. 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. Palm Beach County also had 13 tornado days in that period. In Boca Raton, 24.7% 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 Boca Raton 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
- Multi-zone systems cost more per room, but they run off a single outdoor unit.
- Rinse the indoor filters once a month during heavy use.
- If winter nights regularly drop below 10°F, pay for a cold-climate model.
