Salem Weather and HVAC Load
NOAA's 1991-2020 climate normals put Salem at 4,340 heating degree days and 401 cooling degree days per year. Heating is the bigger job here, and furnaces and heat pumps in Salem put in far more hours than the air conditioner. On average, Salem gets 49 freezing nights and 18 days above 90°F per year. Snowfall averages about 1 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.

Marion County had 2 hail days and 2 days with damaging thunderstorm winds from 2020 through 2025, according to NOAA storm records. The largest hail reported was 1 inches across. Storms here are more likely to cause power surges than coil damage, so a surge protector on the outdoor unit is worth the small cost.

Oregon Permits, Efficiency Rules and Rebates
Oregon 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 Salem. If a bidder suggests skipping it, move on. Also ask for a Oregon 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
