The ductwork is usually original, and leaky joints are common. Fresno has roughly 89,000 owner-occupied homes, or 49.7% of households. The median home value is $348,500, and median household income is $66,804. We use both figures to adjust labor and pricing for this page.
Fresno County had 1 hail day and 7 days with damaging thunderstorm winds from 2020 through 2025, according to NOAA storm records. 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.
