Brandon Housing Stock
Half the homes in Brandon were built before 1992 (Census ACS median), so the typical house is about 34 years old. Plenty of houses from this period still run original 1990s or early-2000s equipment, which is past its expected service life. Brandon has roughly 25,000 owner-occupied homes, or 55.6% of households. Homes here have a median value of $293,800 and households a median income of $77,068. Those two numbers drive the labor adjustment in our estimate.
NOAA storm reports for Hillsborough County show 5 hail days and 18 days with damaging thunderstorm winds over the six years from 2020 to 2025. The largest hail reported was 3 inches across. Storms here are more likely to cause power surges than coil damage, so a surge protector on the outdoor unit is worth the small cost. Hillsborough County also had 4 tornado days in that period.

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 Brandon 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

- Replacing both pieces at once usually costs less than two separate jobs a few years apart.
- Get one quote for a heat pump system and one for a furnace plus AC.
