Detroit Weather and HVAC Load

In a normal year, Detroit racks up 6,137 heating and 803 cooling degree days (NOAA 1991-2020 normals). Heating is the bigger job here, and furnaces and heat pumps in Detroit put in far more hours than the air conditioner. On average, Detroit gets 125 freezing nights and 17 days above 90°F per year. Snowfall averages about 31 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.

Detroit Housing Stock

Census figures put the median build year in Detroit at 1947, so a typical house here has about 79 years on it. Many houses that age were built with hot-water or steam heat, and plenty still run cast-iron boilers and radiators. Owners live in 49.7% of occupied homes, roughly 126,000 households. With a median household income of $39,575 and a median home value of $76,800, local labor rates come out below the national middle in our model.

NOAA storm reports for Wayne County show 5 hail days and 30 days with damaging thunderstorm winds over the six years from 2020 to 2025. The largest hail reported was 1.5 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. Wayne County also had 2 tornado days in that period.

When Replacement Makes Sense

  • Leaks, rust, or pressure that keeps dropping
  • The pilot or ignition keeps failing
  • Fuel bills keep going up

What Moves the Price

  • Condensing or non-condensing boiler
  • Pumps, zone valves and the piping around the boiler
  • A combi boiler that also makes your hot water
  • A new chimney liner or venting
  • Fuel type: gas, oil or propane

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 Detroit; 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.
  • For a steam system, hire a contractor who works on steam regularly.
  • Ask for a heat-loss calculation. A lot of old boilers are much bigger than the house needs.
