Dearborn Heights Weather and HVAC Load
In a normal year, Dearborn Heights racks up 6,365 heating and 735 cooling degree days (NOAA 1991-2020 normals). Heating is the bigger job here, and furnaces and heat pumps in Dearborn Heights put in far more hours than the air conditioner. On average, Dearborn Heights gets 136 freezing nights and 16 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.

Dearborn Heights Housing Stock
Census figures put the median build year in Dearborn Heights at 1958, so a typical house here has about 68 years on it. Houses that old often still have duct runs sized for an old coal or oil furnace and 60- or 100-amp electrical panels. Both can add cost when new equipment goes in. About 16,000 households here own their home, 71.6% of the occupied total. Homes here have a median value of $174,900 and households a median income of $61,035. Those two numbers drive the labor adjustment in our estimate.
Wayne County had 5 hail days and 30 days with damaging thunderstorm winds from 2020 through 2025, according to NOAA storm records. 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
- Some rooms stay cold, the burner short-cycles, or the ignitor keeps failing
- A repair quote runs past a third of the cost of a new unit
- A tech found a cracked heat exchanger, or the CO detector has gone off
- The furnace is 15 to 20 years old or more
What Moves the Price
- Condition of the existing ductwork and any changes it needs
- AFUE rating: a basic 80% unit vs. a 96% condensing furnace
- Permit and inspection fees, which the local building department sets
- BTU size, which should come from a Manual J load calculation
- New PVC venting if you move to a condensing model
- Single-stage, two-stage or modulating gas valve
We raised the national figures about 4% for Dearborn Heights using local income, home values and the equipment size this climate needs. Real bids can still come in outside the range, so collect three written quotes.

- Removing and hauling away the old furnace
- The permit and the manufacturer warranty registration
- The new furnace, filter rack and thermostat wiring
- Gas line and vent connections
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. Equipment replacements in Dearborn Heights generally need a mechanical permit, and a reputable contractor will pull it for you. Ask for their Michigan 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
- Look up utility rebates on 95%+ AFUE units before you buy.
- Replace it in early fall if you can. A no-heat emergency in January costs more and leaves you fewer choices.
- Make sure all three quotes are for the same AFUE and staging, or you can't compare them.
