Rock Springs Weather and HVAC Load
NOAA's 1991-2020 climate normals put Rock Springs at 7,552 heating degree days and 301 cooling degree days per year. Heating is the bigger job here, and furnaces and heat pumps in Rock Springs put in far more hours than the air conditioner. A normal year brings 184 nights at or below freezing and 15 days over 90°F. Snowfall averages about 31 inches. For a 2,000 sq ft house, this climate points to a heating load somewhere near 75,000 BTU/h. Treat that as a starting number. A Manual J calculation will move it up or down based on insulation and windows.

Wyoming Permits, Efficiency Rules and Rebates
Wyoming 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. Expect the contractor to pull a mechanical permit for a replacement job in Rock Springs. If a bidder suggests skipping it, move on. Also ask for a Wyoming 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.
