HVAC Repair in Ann Arbor, Michigan

Heating and cooling repair in Ann Arbor is a matter of parts on the truck and a person who knows what fails. Ignitors and flame sensors in October, capacitors and contactors in June, float switches whenever the humidity spikes near Briarwood Mall, control boards after the DTE Energy grid takes a lightning hit in a summer storm. Temprasure carries all of it, and because Al runs the calls himself there is no dispatcher between you and the person turning the wrench. Ann Arbor homeowners get the same flat-rate pricing, same-day priority on no-heat and no-cooling calls, and the same straight talk about repair versus replacement that our Ypsilanti neighbors get.

Ann Arbor houses and what that means for hvac repair

Ann Arbor gives us almost every housing type in one zip code. The Old West Side and Old Fourth Ward are full of 1880s–1920s frame houses with stone or rubble foundations, fieldstone basements that stay damp, and furnaces that replaced boilers or gravity units sometime in the 1960s or 70s. Many of those homes still have cast-iron radiators fed by a boiler, and a surprising number have both a boiler and a separate forced-air system added for cooling. Burns Park and Ann Arbor Hills houses are larger 1920s–50s builds with plaster walls, so getting a second return or a bigger supply trunk in is slow work. The ranches and split-levels of the west side were built with 80,000 to 100,000 BTU furnaces that are now oversized for insulated versions of the same house. Condos near Briarwood and Pittsfield Village often have furnaces in closets or attics with tight clearances. Student rentals near campus run the oldest equipment in the city, and landlords routinely call us for emergency service and new-purchase inspections.

Electrical service in Ann Arbor comes from DTE Energy, and summer storms rolling across Washtenaw County are hard on HVAC controls. A voltage spike takes out a furnace control board or a condenser contactor, a brief outage lets the sump pit near the furnace fill, and a brownout on a hot afternoon leaves a tired compressor trying to start on a weak capacitor. We see all three in Ann Arbor every year. Our repair visit includes checking line voltage at the disconnect and at the furnace, inspecting the board for scorching, and testing capacitors under load rather than replacing parts one at a time until something works. For homes near Briarwood Mall where outages are frequent, we also talk about surge protection at the furnace and a float switch that shuts the AC down before water reaches the blower.

With about 123,000, the largest city in Washtenaw County residents and housing that runs from the pre-war two-stories and 1950s–60s ranches, with university-era infill on every side around Kerrytown to the newer streets near Northside and Lower Town, Ann Arbor keeps us busy year-round. The equipment is on DTE Energy for heat and DTE Energy for cooling, the basements near Michigan Stadium are prone to the same moisture issues as the rest of Washtenaw County, and the ductwork in a lot of these houses was never sized for the air conditioner that was bolted on later. We are 7 miles away, we service every brand, and we quote a flat rate before we start.

Local details we plan around in Ann Arbor

• A lot of pre-1950 houses have been converted to duplexes or student rentals, which means two systems crammed into one basement and undersized gas lines serving both.
• The large number of boiler-and-radiator homes means we see hydronic work here far more than anywhere else in our radius.
• Ann Arbor has its own building department with its own mechanical permit process, and inspectors here want to see combustion air, condensate routing and flue sizing done by the book.
• The Huron River cuts a deep valley through the north side of Ann Arbor, and the Northside, Lower Town and Gallup Park neighborhoods feel it as morning fog, heavier dew and basements that sweat in July. The downtown core holds heat with all its brick and pavement, so attics and upper floors there run several degrees hotter than the leafy blocks of Burns Park and the Old West Side, where mature oaks and maples shade roofs and cut peak cooling loads noticeably.
