Nampa Housing Stock
Census figures put the median build year in Nampa at 1998, so a typical house here has about 28 years on it. Plenty of houses from this period still run original 1990s or early-2000s equipment, which is past its expected service life. Nampa has roughly 27,000 owner-occupied homes, or 71.4% of households. With a median household income of $72,122 and a median home value of $332,500, 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.
