DeSoto Housing Stock
The median DeSoto home dates to 1993, according to the Census ACS. That makes the typical house about 33 years old. Plenty of houses from this period still run original 1990s or early-2000s equipment, which is past its expected service life. Owners live in 70.5% of occupied homes, roughly 15,000 households. Homes here have a median value of $282,600 and households a median income of $83,256. Those two numbers drive the labor adjustment in our estimate.
NOAA storm reports for Dallas County show 44 hail days and 30 days with damaging thunderstorm winds over the six years from 2020 to 2025. The largest hail reported was 4 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. Dallas County also had 4 tornado days in that period.
