Heating and cooling in Dearborn
Selling a house in Dearborn means passing a city inspection first. The city requires a Certificate of Occupancy before closing: an inspector completes a pre-sale inspection, and every cited violation must be corrected and re-inspected. Rentals follow the same inspection on a 3-year cycle. The page describes basic safety and property maintenance and does not list furnace items, so do not assume the furnace is checked. Mechanical permits cover anything that affects heating, air conditioning or ventilation, and most can be filed through BS&A Online Services at the Economic Development office, Dearborn Administrative Center, 16901 Michigan Ave, 311 or 313-943-2150.
The city's October 2025 fee file lists a $100 administrative fee plus an $80 minimum permit fee, with a tandem permit when heating and cooling are pulled together at a $110 minimum. Housing is old: 84.0 percent of homes predate 1980. DTE Electric and DTE Gas are the only utilities whose territory covers the city. Dearborn's nearest station in our table is Detroit Metro airport, at about 6,067 heating degree days (base 65 F).
The Home Rehabilitation Program offers income-qualified owners a zero-interest deferred loan that can cover furnace replacement; it is a loan, not a rebate. Melvindale and Allen Park are close, and our furnace repair page is the place to start.

We have collected no quotes for Dearborn, so there is no price for the city itself. The statewide estimates are on each service page, and the Michigan page shows what technicians are paid (the Michigan mean in BLS data for May 2025 is $31.01 an hour, which is pay, not price) and the permit fees that are published. How we estimate costs.
Permits for heating and cooling work in Dearborn
Mechanical work may not start until a permit is issued, except replacement of minor parts. A furnace, central air conditioner or heat pump replacement is not on LARA's exemption list, which is our inference from the list, not a sentence LARA wrote.
