Heating and cooling in Clawson
Clawson's furnaces face the Detroit Metro airport normals, which we use as the nearest station: about 6,067 heating degree days a year (base 65 F), in IECC climate zone 5, Cold. The city is small and old: 84.2 percent of homes were built before 1980, and the median value is $250,800, next to Royal Oak at 83.1 percent and $305,900, 2.0 miles away. The city's Building and Planning page is at cityofclawson.com, and its printed phone is the city main line, (248) 435-4500.
That page gives only an outline, so ask the counter whether furnace and AC permits come through Building and Planning, and note the name of the person you speak to and the date. A replacement is not on LARA's exemption list. Efficiency is another thing to ask about. ENERGY STAR sets 97 percent AFUE for gas furnaces in the North, a list Michigan is on, and the federal floor is 80 percent.
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 Clawson
We have collected no quotes for Clawson, 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 Clawson
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.
