Salt Lake City Weather and HVAC Load
NOAA's 1991-2020 climate normals put Salt Lake City at 4,724 heating degree days and 1,401 cooling degree days per year. Heating is the bigger job here, and furnaces and heat pumps in Salt Lake City put in far more hours than the air conditioner. A normal year brings 81 nights at or below freezing and 45 days over 90°F. Snowfall averages about 49 inches. For a 2,000 sq ft house, this climate points to a heating load somewhere near 55,000 BTU/h. Treat that as a starting number. A Manual J calculation will move it up or down based on insulation and windows.

Utah Licensing and Efficiency Rules
Utah 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 Utah 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.
- If the furnace is past 15, ask the tech to price both a repair and a replacement.
- Have the model and serial number from the furnace label handy. Parts get ordered faster.
