Warren Weather and HVAC Load
NOAA's 1991-2020 climate normals put Warren at 6,105 heating degree days and 854 cooling degree days per year. Heating is the bigger job here, and furnaces and heat pumps in Warren put in far more hours than the air conditioner. A normal year brings 112 nights at or below freezing and 13 days over 90°F. Snowfall averages about 28 inches. For a 2,000 sq ft house, this climate points to a heating load somewhere near 65,000 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.

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. Plan on a mechanical permit for most replacements in Warren; the contractor normally pulls it. Before you sign, ask each bidder for their 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
- Ask your gas or oil company about rebates on condensing boilers.
- A combi boiler frees up space and replaces your water heater.
- For a steam system, hire a contractor who works on steam regularly.
