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.

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.
Before You Hire
- A combi boiler frees up space and replaces your water heater.
- For a steam system, hire a contractor who works on steam regularly.
