Heat Pump Maintenance in Chelsea, Michigan

A heat pump in Chelsea never gets a season off. It cools the house through the muggy stretch of July, carries the heating load through fall and spring, and reverses itself dozens of times a day in January to shed frost. Temprasure maintains heat pumps across Chelsea, MI on a two-visit schedule built for that workload: a fall tune-up focused on defrost, the reversing valve and backup heat, and a spring tune-up focused on coils, electrical and cooling charge. We are about 36 minutes away in Ypsilanti, and both visits are a flat rate with no dispatch fee.

Chelsea houses and what that means for heat pump maintenance

The in-town housing is dominated by 1890s–1940s two-stories, foursquares and bungalows on fieldstone or early block basements with plaster walls and ductwork retrofitted into a house that was designed for a coal furnace or stoves. Flues in these homes are often unlined brick, and we see a lot of 80 percent furnaces that have been venting into a chimney that should have been relined years ago. The post-war ring along McKinley Street and Freer Road is 1950s–70s ranches and capes, some on slabs, with electric baseboard still present in a few. Chelsea Fairways, Heritage Pointe and the other 1990s–2010s subdivisions are colonials and ranches on full basements with builder-grade 80 percent furnaces and single-stage air conditioners that are now hitting replacement age. Outside the city on Werkner, Waterloo and Cavanaugh Lake Roads, we see lakefront cottages that were winterized, farmhouses with multiple additions, and newer acreage homes on propane and well water.

Winter drainage is the physical maintenance item for Chelsea 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 Chelsea Hospital 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 48118 gets priority in winter, and the drive from Ypsilanti to Chelsea is about 36 minutes. The houses here, from the 1890s–1920s village homes and 1990s–2010s subdivisions on the edges around Chelsea Fairways and Werkner Road area to the newer builds near Old US-12 corridor, run almost entirely on Consumers 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 Chelsea

• Electric service is split between Consumers Energy and DTE depending on the exact address, and homes just outside town may be on one for gas and the other for electric.
• Outside the city limits, propane furnaces and water heaters are routine, and propane conversions and regulator problems are a normal part of our Chelsea calls.
• Permits for city addresses go through Chelsea's building department, while Lima, Sylvan and Lyndon Township addresses go through Washtenaw County.
• Chelsea is high and open compared with the river towns to the east, and it gets more wind and a bit more snow than Ypsilanti, with polar vortex nights that run a few degrees colder. The lakes in the Waterloo Recreation Area and around Cavanaugh Lake add summer humidity for the homes closest to them. Heavy tree cover downtown and on the older residential streets shades roofs in July, while the newer subdivisions on the east side have little mature canopy yet.
