St. Petersburg Housing Stock
The median St. Petersburg home dates to 1969, according to the Census ACS. That makes the typical house about 57 years old. A lot of these homes are on their second or third system by now. The ductwork is usually original, and leaky joints are common. Owners live in 63% of occupied homes, roughly 74,000 households. The median home value is $331,500, and median household income is $73,118. We use both figures to adjust labor and pricing for this page.
Between 2020 and 2025, NOAA's Storm Events Database logged 2 hail days and 18 days with damaging thunderstorm winds in Pinellas County. The largest hail reported was 1 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. Pinellas County also had 12 tornado days in that period. In St. Petersburg, 20.5% of residents are 65 or older. For older adults, a house with no heat in January or no AC during a heat wave is a medical risk. Mention it when you call, since many companies put those calls first.
