Heating and cooling in Hazel Park
Hazel Park's Building Department receives building, electrical and mechanical plans and permits, at 111 East Nine Mile Rd, which makes this one of the easier cities to find the right counter. City Hall's number is 248-546-7000; the page prints no building-specific phone. The mechanical fee is not confirmed here, so ask before a contractor quotes one. The median home is $141,200, with 86.6 percent built before 1980. Ferndale, 1.7 miles away, has nearly the same age profile at 90.7 percent and a median of $233,600, so the same sort of furnace is heating a house with a much lower median value on this side.
Older homes more often have older furnaces and ductwork, and with a lower house value the repair-or-replace question tends to be harder; use our repair or replace tool. We use the Detroit Metro airport normals as our nearest station, our pick, not NOAA's assignment: about 6,067 heating degree days a year (base 65 F). The county sits in IECC climate zone 5. Warren, 4.3 miles away, has a 2023 form listing $80 for a residential furnace permit, a medium-confidence figure because the form is three years old; do not assume Hazel Park's matches. Neighbors are Ferndale and Madison Heights.
The wider area: Southeast Michigan
Southeast Michigan is the state's largest furnace market, and Detroit Metro airport averages about 6,067 heating degree days and about 847 cooling degree days a year (NOAA 1991 to 2020 normals, base 65 F). The Ann Arbor station reads higher, at about 6,501 heating degree days, so a house in Washtenaw County heats a little longer than one in Wayne. The DOE and PNNL county table puts Wayne, Oakland, Macomb and Washtenaw counties in IECC climate zone 5. The cities we researched here, including Detroit, Warren, Sterling Heights and Ann Arbor, enforce the mechanical code locally. As of Oct 19, 2026, MiHER's income-qualified applications are suspended in the Detroit and Warren districts, and Ann Arbor residents can look at the city's A2ZERO heat pump rebate.
What heating and cooling work costs near Hazel Park
We have collected no quotes for Hazel Park, 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 Hazel Park
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.
