Boynton Beach Weather and HVAC Load
Boynton Beach logs 229 heating degree days and 3,799 cooling degree days in a normal year, based on the closest NOAA weather station. 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 66 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.

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). Plan on a mechanical permit for most replacements in Boynton Beach; the contractor normally pulls it. Before you sign, ask each bidder for their Florida license or registration number and proof of insurance. 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.
