Lafayette Housing Stock
The median Lafayette home dates to 1981, according to the Census ACS. That makes the typical house about 45 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 55% of occupied homes, roughly 29,000 households. The median home value is $251,300, and median household income is $61,454. We use both figures to adjust labor and pricing for this page.
Between 2020 and 2025, NOAA's Storm Events Database logged 7 hail days and 14 days with damaging thunderstorm winds in Lafayette Parish. The largest hail reported was 1.75 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.
