Laramie County also had 4 tornado days in that period. In Cheyenne, 18% of residents are 65 or older. For older adults, a house with no heat in January or no AC during a heat wave is a medical risk.

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. Most repairs don't need a permit. Anyone who opens the refrigerant circuit does need EPA Section 608 certification, and in Wyoming the company should carry a state license or registration. Ask for both.
Before You Hire
- If you see ice, shut the system off. Running it frozen can kill the compressor.
- Ask for the per-pound refrigerant price before any work starts.
- Swap the air filter and check the breaker before you call anyone.
