Denver Housing Stock
Half the homes in Denver were built before 1974 (Census ACS median), so the typical house is about 52 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 49.1% of occupied homes, roughly 162,000 households. Homes here have a median value of $586,700 and households a median income of $91,681. Those two numbers drive the labor adjustment in our estimate.
Between 2020 and 2025, NOAA's Storm Events Database logged 15 hail days and 14 days with damaging thunderstorm winds in Denver County. The largest hail reported was 2.75 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. Denver County also had 2 tornado days in that period.
