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
- Light frost on the outdoor unit in winter is normal. A solid block of ice is not.
- Keep two feet clear around the outdoor unit, including snow.
- Many heat pumps carry a 10-year parts warranty if they were registered. Find out whether yours was.

Heat Pump Repair Questions from Idaho Falls Homeowners
What does heat pump repair cost in Idaho Falls?
Most bills land between $210 and $1,010, including the service call. A typical visit is about $650. Night and weekend calls cost more.
Is it normal for a heat pump to freeze?
A thin layer of frost in winter is normal, and the defrost cycle should clear it. Heavy ice that stays usually means a defrost control or airflow problem.
Why is my heat pump blowing cold air?
For a few minutes during a defrost cycle, that's normal. If it keeps going, the usual causes are a stuck reversing valve, low refrigerant or a thermostat set to the wrong mode.
