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 Permits, Efficiency Rules and Rebates
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. Plan on a mechanical permit for most replacements in Salt Lake City; the contractor normally pulls it. Before you sign, ask each bidder for their Utah license or registration number and proof of insurance. The federal 25C tax credit ended for equipment installed after December 31, 2025, so incentives now come mostly from utilities and state programs. Check your electric and gas utility's rebate page before you pick equipment.
