Caldwell Housing Stock
The median Caldwell home dates to 2002, according to the Census ACS. That makes the typical house about 24 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 70.7% of occupied homes, roughly 15,000 households. With a median household income of $66,663 and a median home value of $322,100, local labor rates come out near the national middle in our model.
Between 2020 and 2025, NOAA's Storm Events Database logged 2 hail days and 3 days with damaging thunderstorm winds in Canyon County. The largest hail reported was 1.5 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.
