Half the homes in Galveston were built before 1973 (Census ACS median), so the typical house is about 53 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 46.7% of occupied homes, roughly 11,000 households. The median home value is $294,300, and median household income is $57,216. We use both figures to adjust labor and pricing for this page.
Galveston County had 7 hail days and 17 days with damaging thunderstorm winds from 2020 through 2025, according to NOAA storm records. The largest hail reported was 2.75 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. Galveston County also had 4 tornado days in that period. In Galveston, 20.1% 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.
