Idaho Falls Weather and HVAC Load
NOAA's 1991-2020 climate normals put Idaho Falls at 7,144 heating degree days and 443 cooling degree days per year. Heating is the bigger job here. The AC still runs every summer, but it works far fewer hours than the furnace does. A normal year brings 166 nights at or below freezing and 28 days over 90°F. Snowfall averages about 66 inches. On the cooling side, a 2,000 sq ft house here usually needs around 2.5 tons. A tight, well-insulated house may get by with half a ton less.

Bonneville County had 8 hail days and 26 days with damaging thunderstorm winds from 2020 through 2025, according to NOAA storm records. The largest hail reported was 1.25 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.

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
- Swap the air filter and check the breaker before you call anyone.
- 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.
