Heat Pump Maintenance in Pittsfield Township, Michigan

A heat pump that is slightly out of spec in Pittsfield Township costs more to run than a furnace that is slightly out of spec, because the heat pump's fallback is electric resistance heat at several times the cost. That is the whole case for twice-a-year maintenance, and it is why Temprasure runs a separate fall and spring visit for Pittsfield Township, MI heat pumps rather than a single spring check. We serve every address from the Pittsfield Township Hall on Michigan Avenue to Carpenter Road corridor at one flat rate per visit, and we tell you honestly when an aging unit is reaching the point where a new cold-climate system with DTE Energy rebates makes more sense.

Pittsfield Township houses and what that means for heat pump maintenance

The heating-and-cooling story in Pittsfield is really the story of builder-grade equipment reaching its twenties. Thousands of colonials and two-story traditionals went up between about 1992 and 2012 on full poured-concrete basements, and most were handed over with a standard 80 percent furnace, a 10 to 13 SEER air conditioner, a bypass humidifier that nobody ever changed the pad on, and a 40-gallon atmospheric water heater. We are now replacing those systems in bulk, often two or three in the same subdivision in one week. The older pockets along Carpenter Road, Packard Road and Golfside Road are 1960s–70s ranches and tri-levels with crawlspaces or partial basements and ductwork that runs through unconditioned space. Townhouse and condo complexes near Ellsworth Road and State Street use furnaces in utility closets with limited combustion air. The newest homes off Textile Road came with 90-plus furnaces and R-410A condensers and are mostly still in warranty territory.

Winter drainage is the physical maintenance item for Pittsfield Township heat pumps. Every defrost cycle sends water off the outdoor coil, and in a Washtenaw County January that water freezes under and around the unit. A heat pump on a pad at grade near the Pittsfield Township Hall on Michigan Avenue ends up frozen into a sheet of ice by February, with the coil's bottom rows blocked and the fan working against it. On the fall visit we check the riser stand height, the drainage path and the clearance around the unit, and where the original installer set it directly on a pad we recommend a stand. In spring we check whether the ice did any damage to the fan, the coil fins or the base pan.

A no-heat call from 48108 gets priority in winter, and the drive from Ypsilanti to Pittsfield Township is about 12 minutes. The houses here, from the 1990s–2010s subdivision colonials, with 1960s–70s ranches along the older corridors around Arbor Meadows and Stonebridge to the newer builds near Centennial Park, run almost entirely on DTE Energy, and the failures we see are the same ones we see everywhere in Southeast Michigan: dirty flame sensors, failed hot-surface ignitors, stuck pressure switches, cracked exchangers on furnaces that should have been retired. We diagnose with a combustion analyzer and a manometer, not a flashlight, and we show you the reading before we quote the repair.

Local details we plan around in Pittsfield Township

• Garages here were built with the furnace room just inside, so combustion-air openings into the garage are a code issue we correct on many replacements.
• The whole township is on DTE gas and electric, with municipal water from Ann Arbor or Ypsilanti depending on the subdivision, so well water is rare except on a few older parcels south of Textile Road.
• Many 1990s subdivisions were plumbed with flexible duct branches stapled to basement joists, and crushed or disconnected runs are the usual cause of a cold upstairs bedroom.
• Pittsfield is flat, open former farmland, and the newer subdivisions have not grown enough tree cover yet to matter, so south- and west-facing colonials bake in July and condensers run long hours. Winter wind sweeps across the fields from the west with little to slow it, which pushes heating loads on the exposed end units of every subdivision. Drainage is managed through retention ponds, and homes backing up to them run a bit damper in the basement.
