Sterling Heights Weather and HVAC Load
In a normal year, Sterling Heights racks up 6,550 heating and 633 cooling degree days (NOAA 1991-2020 normals). Heating is the bigger job here, and furnaces and heat pumps in Sterling Heights put in far more hours than the air conditioner. On average, Sterling Heights gets 129 freezing nights and 11 days above 90°F per year. Snowfall averages about 32 inches. For a 2,000 sq ft house, this climate points to a heating load somewhere near 70,000 BTU/h. Treat that as a starting number. A Manual J calculation will move it up or down based on insulation and windows.

Between 2020 and 2025, NOAA's Storm Events Database logged 7 hail days and 34 days with damaging thunderstorm winds in Macomb 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. Macomb County also had 2 tornado days in that period. In Sterling Heights, 18.4% of residents are 65 or older. For older adults, a house with no heat in January or no AC during a heat wave is a medical risk.

Michigan Permits, Efficiency Rules and Rebates
Michigan 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 Sterling Heights. If a bidder suggests skipping it, move on. Also ask for a Michigan 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
