Sanford Housing Stock
Census figures put the median build year in Sanford at 1991, so a typical house here has about 35 years on it. Plenty of houses from this period still run original 1990s or early-2000s equipment, which is past its expected service life. About 12,000 households here own their home, 51.1% of the occupied total. The median home value is $272,900, and median household income is $62,877. We use both figures to adjust labor and pricing for this page.
Seminole County had 6 hail days and 14 days with damaging thunderstorm winds from 2020 through 2025, according to NOAA storm records. 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. Seminole County also had 3 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). Plan on a mechanical permit for most replacements in Sanford; 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
- Ask for a heat-loss calculation. A lot of old boilers are much bigger than the house needs.
- A combi boiler frees up space and replaces your water heater.
- Ask your gas or oil company about rebates on condensing boilers.
