Pasadena Housing Stock
The median Pasadena home dates to 1976, according to the Census ACS. That makes the typical house about 50 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 54.2% of occupied homes, roughly 27,000 households. Homes here have a median value of $193,600 and households a median income of $64,270. Those two numbers drive the labor adjustment in our estimate.
Between 2020 and 2025, NOAA's Storm Events Database logged 28 hail days and 44 days with damaging thunderstorm winds in Harris County. The largest hail reported was 2 inches across. Hail flattens the thin aluminum fins on condenser coils and cuts airflow. After a big storm, take a look at the outdoor unit; homeowners insurance often covers the damage. Harris County also had 9 tornado days in that period.
