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 Licensing and Efficiency Rules
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). A repair usually goes ahead without a permit, but the tech handling refrigerant must hold EPA 608 certification. Ask the company for its Florida license or registration number before the visit.
Before You Hire
- If the CO alarm goes off, get everyone outside and call 911 or the gas company before you call an HVAC company.
- Ask what the emergency fee is before the truck is sent.
- Keep space heaters away from curtains and bedding, and never heat the house with a gas oven.
