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.
