Census figures put the median build year in Gillette at 1988, so a typical house here has about 38 years on it. Plenty of houses from this period still run original 1990s or early-2000s equipment, which is past its expected service life. Gillette has roughly 9,500 owner-occupied homes, or 75.2% of households. The median home value is $257,200, and median household income is $90,699. We use both figures to adjust labor and pricing for this page.
NOAA storm reports for Campbell County show 31 hail days and 36 days with damaging thunderstorm winds over the six years from 2020 to 2025. The largest hail reported was 3 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.

Wyoming Licensing and Efficiency Rules
Wyoming 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. A repair usually goes ahead without a permit, but the tech handling refrigerant must hold EPA 608 certification. Ask the company for its Wyoming license or registration number before the visit.
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.
- Ask what the emergency fee is before the truck is sent.
