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.

NOAA storm reports for Salt Lake County show 8 hail days and 53 days with damaging thunderstorm winds over the six years from 2020 to 2025. 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.
When Replacement Makes Sense
- Gas or electric bills keep climbing even though usage hasn't changed
- Some rooms stay cold, the burner short-cycles, or the ignitor keeps failing
- A tech found a cracked heat exchanger, or the CO detector has gone off
- A repair quote runs past a third of the cost of a new unit
What Moves the Price
- Single-stage, two-stage or modulating gas valve
- AFUE rating: a basic 80% unit vs. a 96% condensing furnace
- BTU size, which should come from a Manual J load calculation
- Permit and inspection fees, which the local building department sets
- New PVC venting if you move to a condensing model
- Condition of the existing ductwork and any changes it needs
For Salt Lake City we raised the national figures about 19%, based on local income, home values and climate-based equipment sizing. Get at least three written quotes; real bids can land outside this range.

- Gas line and vent connections
- The new furnace, filter rack and thermostat wiring
- Removing and hauling away the old furnace
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
- Make sure all three quotes are for the same AFUE and staging, or you can't compare them.
- Replace it in early fall if you can. A no-heat emergency in January costs more and leaves you fewer choices.
- Look up utility rebates on 95%+ AFUE units before you buy.
