Thermostat Installation in Milan, Michigan

A thermostat call from Milan is often a thermostat call only on the surface. The screen is blank in 48160, the homeowner assumes the unit died, and it turns out a float switch under the AC coil tripped or the low-voltage fuse on the furnace board blew during the last DTE Energy storm. Temprasure diagnoses the 24-volt circuit before replacing anything on a Milan visit, because a new thermostat on a dead circuit is still blank. When a new thermostat is the right answer for your 1890s–1930s railroad-town homes and 1960s–2000s ranches and colonials house near Uptown Milan, we install it with a proper common wire and set it up for the furnace, air conditioner, humidifier and heat pump it is actually controlling.

Milan houses and what that means for thermostats

Downtown Milan and the streets around Wilson Park and Hurd Street are 1880s–1930s frame houses on stone or block basements with the original furnace location in a tight corner and a gas line that has been extended a few times. Several still have gravity-furnace duct trunks that were reused when forced air went in. The 1950s–70s ranches along Dexter Street, County Street and the Carpenter Road side of town often sit on crawlspaces or slabs, and electric baseboard or wall furnaces show up in a few that never got ductwork. Newer subdivisions off Platt Road and Arkona Road are 1990s–2000s colonials and ranches on full basements with 80 percent furnaces and R-22 condensers that are now getting replaced in bulk. On the Monroe County side and out Redman Road, we see older farmhouses with additions, mobile homes with package units, and acreage homes on well and septic.

The common wire problem is the one we solve most in Milan. The 1890s–1930s railroad-town homes and 1960s–2000s ranches and colonials homes around Uptown Milan were wired with four-conductor thermostat cable when central air was added, and a smart thermostat needs a fifth conductor for continuous power. Without it, the thermostat steals power through the furnace circuit, the screen goes blank during a heating call, the Wi-Fi drops, and the furnace board sees pulses it interprets as calls and starts short-cycling. On a Milan install we open the furnace, find an unused conductor if one exists, land it on the C terminal at the board, and if there is nothing spare we fit a power extender kit at the furnace or fish a new cable where the wall allows. The thermostat then has real power and the furnace sees a clean call.

Our trucks are in Milan most weeks, because Washtenaw County is where a large share of our work is and 48160 is a short run from Ypsilanti. The 1890s–1930s railroad-town homes and 1960s–2000s ranches and colonials that line the streets near Dexter Street corridor and the Hack House Museum have usually been through two or three furnaces and at least one air conditioner, often installed by different companies with different ideas about ductwork, and sorting that out is what a whole-system visit is for. We check the furnace, the coil, the condenser, the thermostat and the ducts as one system, because in a Milan house they fail as one system.

Local details we plan around in Milan

• Rural addresses outside the city, especially toward Redman Road and the Monroe County side, are often on propane and private wells rather than DTE gas.
• The county line runs through town, so permits for a Milan address may go through the City of Milan, Washtenaw County or Monroe County depending on which side of the line the house sits.
• Milan's municipal water is drawn from wells and is hard, which shows up as sediment in water heaters and scale on humidifier pads.
• Milan is low, flat and open, in the Saline River bottomland, and summer humidity lingers in the older neighborhoods close to the river. The town is far enough south that it occasionally picks up weather coming off Lake Erie that misses Ypsilanti, including heavier late-winter snow and ice. With little high ground and few windbreaks between the subdivisions and the fields to the south, winter wind drives infiltration on the exposed sides of newer homes.
