Boise City Weather and HVAC Load
Boise City logs 5,320 heating degree days and 1,045 cooling degree days in a normal year, based on the closest NOAA weather station. Heating is the bigger job here, and furnaces and heat pumps in Boise City put in far more hours than the air conditioner. On average, Boise City gets 108 freezing nights and 55 days above 90°F per year. Snowfall averages about 18 inches. For a 2,000 sq ft house, this climate points to a heating load somewhere near 60,000 BTU/h. Treat that as a starting number. A Manual J calculation will move it up or down based on insulation and windows.

With a median household income of $81,308 and a median home value of $456,000, local labor rates come out above the national middle in our model.
Ada County had 2 hail days and 13 days with damaging thunderstorm winds from 2020 through 2025, according to NOAA storm records. The largest hail reported was 1.25 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
- Ask whether the diagnostic fee comes off the repair bill.
- Have the model and serial number from the furnace label handy. Parts get ordered faster.
- If the furnace is past 15, ask the tech to price both a repair and a replacement.
