Furnace Repair in Northville, Michigan

Temprasure has fixed a lot of furnaces in Northville, MI that another company said were done. Not because the other company was lying, but because a furnace that will not stay lit looks terrifying to a homeowner and a quick replacement quote is easy to write. We diagnose with a manometer, a meter and a combustion analyzer, inspect the heat exchanger on every Northville call, and tell you exactly what failed. For Wayne County homes on DTE Energy gas, that usually means a repair in the low hundreds and a furnace that runs another five winters.

Northville houses and what that means for furnace repair

Northville's housing splits sharply between the historic city and the township subdivisions. The Cady Street district and the blocks off Main and Center are 1870s to 1920s two-stories and Queen Annes with Michigan basements, fieldstone walls and low ceilings, where the ductwork was retrofitted and the furnace location is usually a compromise. Some of these houses still have steam or hot-water radiators fed by boilers that have been rebuilt more than once. The Beal Town and Randolph Street blocks have 1920s to 40s bungalows with small basements and finished attics. Beyond the city, the township's 1970s colonials and quad-levels in Northville Hills and Highland Lakes are on block basements with original trunk-and-branch duct, and the 1990s to 2010s subdivisions off Seven Mile, Six Mile and Beck Road are large colonials on poured basements with two systems, zoning and, often, a furnace in the attic serving the second floor. Water heaters in the newer houses are 50-gallon or power-vented gas units, and 75-gallon tanks are not unusual.

The Victorian-era two-stories downtown and 1970s–2010s colonials in the surrounding subdivisions that dominate Northville were often built with a furnace sized for a house with no insulation, single-pane windows and an unfinished basement. Decades of upgrades later, that same furnace, or its like-for-like replacement from the 1990s, is badly oversized, and oversized furnaces short cycle. Every short cycle stresses the ignitor and the heat exchanger, and that is why so many Northville repair calls from Highland Lakes involve a cracked ignitor on a furnace that is otherwise healthy. We fix the ignitor, but we also check the temperature rise and the blower speed, because sometimes a simple adjustment gets a furnace cycling properly and makes the next ignitor last twice as long.

In Northville the furnace is the one appliance nobody thinks about until it fails at 11 p.m. with the temperature falling through the teens. That is when the phone rings, and that is when being 18 miles away matters. We know the Victorian-era two-stories downtown and 1970s–2010s colonials in the surrounding subdivisions along Edenderry and the basements near Ford Field Park, we carry parts for every brand that went into Wayne County homes, and we charge the same flat rate at midnight that we charge at noon. Northville has about 6,100 in the city, with the township pushing the area past 35,000 people and a lot of twenty-year-old furnaces; we would rather tell you yours has five winters left than sell you a new one it does not need.

Local details we plan around in Northville

• Northville's historic district commission reviews exterior changes on designated downtown properties, which can constrain where a condenser or a PVC vent termination goes.
• Attic furnaces in the newer two-system colonials are prone to frozen condensate lines and ignored filters, and we inspect them on every maintenance visit.
• Boilers and radiators are still in service in a meaningful number of downtown houses, and we work on those systems as well as forced air.
• Northville is hilly for Southeast Michigan, sitting on the moraine ridge that runs through Maybury State Park, and the elevation plus heavy tree cover keeps the historic district a few degrees cooler on summer afternoons than the flat suburbs to the south. The Middle Rouge and Johnson Creek run through the downtown valley, and basements along them carry moisture. The open high ground along Seven and Eight Mile takes winter wind with little obstruction.
