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.

Idaho Licensing and Efficiency Rules
Idaho falls in the DOE's North region. New split central air conditioners must meet at least 13.4 SEER2, and heat pumps sold anywhere in the U.S. need 14.3 SEER2 and 7.5 HSPF2. Most repairs don't need a permit. Anyone who opens the refrigerant circuit does need EPA Section 608 certification, and in Idaho the company should carry a state license or registration. Ask for both.
Before You Hire
- Keep space heaters away from curtains and bedding, and never heat the house with a gas oven.
- If the CO alarm goes off, get everyone outside and call 911 or the gas company before you call an HVAC company.
- Maintenance plans often put members first in line for emergency calls.
