Killeen Housing Stock
Half the homes in Killeen were built before 1995 (Census ACS median), so the typical house is about 31 years old. Plenty of houses from this period still run original 1990s or early-2000s equipment, which is past its expected service life. Killeen has roughly 29,000 owner-occupied homes, or 48.6% of households. Homes here have a median value of $196,000 and households a median income of $58,339. Those two numbers drive the labor adjustment in our estimate.
NOAA storm reports for Bell County show 31 hail days and 22 days with damaging thunderstorm winds over the six years from 2020 to 2025. The largest hail reported was 5.68 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. Bell County also had 6 tornado days in that period.
