Provo Weather and HVAC Load
NOAA's 1991-2020 climate normals put Provo at 4,968 heating degree days and 1,204 cooling degree days per year. Heating is the bigger job here, and furnaces and heat pumps in Provo put in far more hours than the air conditioner. A normal year brings 111 nights at or below freezing and 74 days over 90°F. Snowfall averages about 45 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.

Provo Housing Stock
Census figures put the median build year in Provo at 1982, so a typical house here has about 44 years on it. A lot of these homes are on their second or third system by now. The ductwork is usually original, and leaky joints are common. Provo has roughly 14,000 owner-occupied homes, or 39.9% of households. The median home value is $437,100, and median household income is $62,800. We use both figures to adjust labor and pricing for this page.
Between 2020 and 2025, NOAA's Storm Events Database logged 2 hail days and 33 days with damaging thunderstorm winds in Utah County. The largest hail reported was 1.75 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.

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. Equipment replacements in Provo generally need a mechanical permit, and a reputable contractor will pull it for you. Ask for their Utah license or registration number and a certificate of insurance with the quote. 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
- Ask for a duct leakage test. Leaky ducts can lose 20 to 30% of what the system puts out.
- Replacing both pieces at once usually costs less than two separate jobs a few years apart.
- Make every bidder quote the same efficiency ratings, or the prices won't compare.
