Heat Pump Maintenance in Whittaker, Michigan

Here is what the fall heat pump visit looks like at a Whittaker home: the defrost board and sensor get tested and we watch a real defrost cycle, the reversing valve gets shifted both ways, the charge gets checked against the heating chart, the backup strips or the furnace get verified, and on a dual-fuel system the balance point on the thermostat gets set where the equipment and current DTE Energy rates say it belongs. Then we walk outside and check that the unit near the township's Talladay Road ball fields is sitting high enough on its stand to drain and not get buried. That is the Temprasure visit across Whittaker, MI.

Whittaker houses and what that means for heat pump maintenance

Around the crossroads itself the houses are 1880s–1930s farm-village homes with Michigan basements, balloon framing and a forced-air system that was retrofitted into a house built for a wood or coal stove. Those homes tend to have a single undersized return and a furnace that has been replaced two or three times without the ductwork ever being touched. Along Whittaker, Willis and Talladay Roads the common house is a 1970s–90s ranch or raised ranch on a crawlspace or block basement, with the original furnace in a utility room and a condenser that was added in the 1990s on whatever circuit was available. The 2000s subdivisions between Bemis and Willis Roads are colonials and ranches on poured basements with builder-grade equipment that is reaching replacement age, and a lot of them run propane rather than gas. Manufactured homes and modulars on the side roads often have small downflow furnaces and package units that need parts most shops do not stock.

Winter drainage is the physical maintenance item for Whittaker 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 township's Talladay Road ball fields 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.

In Whittaker 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 9 miles away matters. We know the 1970s–90s rural ranches and 2000s acreage homes around an old crossroads along Whittaker Road north toward Bemis and the basements near Stony Creek, we carry parts for every brand that went into Washtenaw County homes, and we charge the same flat rate at midnight that we charge at noon. Whittaker has about a few hundred at the crossroads, with a few thousand using the Whittaker address 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 Whittaker

• DTE gas is available right along Whittaker Road and Willis Road near the crossroads, but a few hundred yards down a side road the gas main ends and propane takes over.
• Every home in Whittaker is on a private well, and the water is hard with enough iron to shorten water heater life and clog humidifier pads within a season.
• Septic drain fields are universal, so we keep high-efficiency furnace condensate out of the septic line with a neutralizer or a separate discharge.
• Whittaker is on flat, open ground with Stony Creek running through the low land to the north and east, and the creek bottom holds moisture that keeps nearby crawlspaces damp through late spring. There is almost no windbreak between the crossroads and the fields to the west, so winter wind hits the exposed side of every house. Summer is humid and still, and homes without mature shade trees run their air conditioning longer than their size would suggest.
