Heating and cooling in Harper Woods
Harper Woods' building department keeps counter hours of Monday to Thursday, 9:00 a.m. to 5:00 p.m., and is closed Fridays. A furnace that quits on a Friday night and the paperwork do not line up, so ask your contractor how a permit gets pulled for urgent work. The office is at 19617 Harper Ave, phone 313-343-2526. Its page says the department reviews plans before permits are issued, but does not mention mechanical permits by name, so call to confirm.
The housing is old: 93.3 percent of homes were built before 1980, and the median home value is $143,600, less than half of Grosse Pointe Woods, 1.5 miles away, at $322,500 with the same share built before 1980. For the owner, the real question is whether a modest house justifies replacement or another repair season, and the repair or replace tool is built to walk that through. Detroit Metro airport's normal, about 6,067 heating degree days a year (base 65 F), stands in here by our choice, and the county is in IECC climate zone 5.
Rebate eligibility follows the utility on your bill; we have not researched which one serves Harper Woods. Neighbors include Grosse Pointe Woods and Eastpointe, 2.1 miles off.
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.
