HVAC Repair in Dexter, Michigan
Dexter is about 32 minutes from our shop in Ypsilanti. One owner-operated shop for the furnace, the air conditioner, the heat pump, the thermostat and the ducts that connect them. Diagnosed properly, quoted flat-rate, fixed on the first trip whenever the part is on the truck.
Heating and cooling repair in Dexter is a matter of parts on the truck and a person who knows what fails. Ignitors and flame sensors in October, capacitors and contactors in June, float switches whenever the humidity spikes near Dexter-Huron Metropark, control boards after the DTE Energy grid takes a lightning hit in a summer storm. Temprasure carries all of it, and because Al runs the calls himself there is no dispatcher between you and the person turning the wrench. Dexter homeowners get the same flat-rate pricing, same-day priority on no-heat and no-cooling calls, and the same straight talk about repair versus replacement that our Ypsilanti neighbors get.
Dexter houses and what that means for hvac repair
In the historic core around Grand Street, Fifth Street and Broad Street, we work on 1840s–1910s frame and brick homes with fieldstone basements, low ceilings and ductwork that has been reworked three or four times. Some of these still have radiators on a boiler and a separate air handler for cooling tucked into an attic. The subdivisions that make up most of Dexter's housing were built between roughly 1994 and 2008. Huron Farms and Dexter Crossing are two-story colonials and cape-style homes on full poured basements, usually with an original 80 percent furnace, a 10 to 12 SEER condenser, and a water heater that has already been replaced once. Westridge and the newer phases carry 90-plus furnaces and two-stage equipment. Beyond the city line, Mast Road, Island Lake Road and North Territorial have 1970s–90s custom homes and older farmhouses on well, septic and sometimes propane, with walkout basements that bring their own moisture issues.
Electrical service in Dexter comes from DTE Energy, and summer storms rolling across Washtenaw County are hard on HVAC controls. A voltage spike takes out a furnace control board or a condenser contactor, a brief outage lets the sump pit near the furnace fill, and a brownout on a hot afternoon leaves a tired compressor trying to start on a weak capacitor. We see all three in Dexter every year. Our repair visit includes checking line voltage at the disconnect and at the furnace, inspecting the board for scorching, and testing capacitors under load rather than replacing parts one at a time until something works. For homes near Dexter-Huron Metropark where outages are frequent, we also talk about surge protection at the furnace and a float switch that shuts the AC down before water reaches the blower.
With about 4,500 in the city, with roughly 15,000 more in the surrounding townships residents and housing that runs from the 1990s–2000s subdivision homes around an 1830s village core around Mill Creek neighborhood to the newer streets near Dexter-Ann Arbor Road corridor, Dexter keeps us busy year-round. The equipment is on DTE Energy for heat and DTE Energy for cooling, the basements near the Dexter Depot are prone to the same moisture issues as the rest of Washtenaw County, and the ductwork in a lot of these houses was never sized for the air conditioner that was bolted on later. We are 19 miles away, we service every brand, and we quote a flat rate before we start.
Local details we plan around in Dexter
- The Huron River and Mill Creek floodplain means basements in the oldest part of town have flooded more than once, and we routinely find equipment that was underwater.
- Dexter's municipal water is softened at the plant, but homes outside the city on private wells have very hard water with iron that attacks water heater anodes quickly.
- The city proper is on DTE gas, but Consumers Energy territory begins just west of town and many addresses with a Dexter mailing address are actually on Consumers or on propane.
- Dexter sits where Mill Creek drops into the Huron River, and the lowest streets near the Cider Mill and Mill Creek Park hold fog and humidity on summer mornings. The town is far enough west that it picks up a little more snow than Ypsilanti and feels polar vortex cold snaps a degree or two harder. Hills and heavy oak cover around Gordon Hall and the metroparks shade a lot of roofs, which holds down cooling loads compared with the open subdivisions to the south.
What Dexter homeowners call about
Blower runs constantly or will not shut off
A stuck fan relay, a thermostat set to ON instead of AUTO, or a furnace that overheated and tripped the limit and is now purging. Constant blower operation on a cold coil also makes the house feel clammy.
Rooms are hot upstairs and cold downstairs
Two-story colonials from the 1970s through the 2000s suffer this almost universally. Causes include undersized returns, uninsulated attic ducts, a blower running on the wrong speed tap or a closed damper nobody remembers.
Furnace runs but the house never warms up
The burners light, the blower runs, and the thermostat setpoint never arrives. Usually a dirty filter choking airflow, a furnace cycling on its high limit, a stuck zone damper or a duct that has come apart in the basement.

Covered on a Dexter visit
- Inducer motor, blower motor and ECM module replacement
- AC capacitor, contactor and condenser fan motor replacement
- Refrigerant leak search and recharge on R-410A, R-454B and remaining R-22 systems
- Heat pump reversing valve, defrost board and outdoor sensor repair
- Thermostat diagnosis, rewiring and replacement, including smart thermostat C-wire fixes
- Condensate drain, pump and float switch repair
How a hvac repair call works
Trace the call from the thermostat down
We confirm what the thermostat is asking for, check the 24-volt circuit and the control board fault history, and only then open the equipment. A lot of repairs are solved in the first fifteen minutes this way.
Test the equipment with instruments
Combustion readings, flame sensor microamps, static pressure, capacitor values, refrigerant pressures and amp draw. We measure instead of guessing so the part we replace is the part that failed.
Show you, then quote one number
You see the burned contactor or the cracked ignitor and hear what it will cost as a single flat rate. The dispatch fee is credited toward the repair when you say yes.

HVAC Repair questions from Dexter
I do not know if it is the furnace or the AC. Does that matter?
No. Tell us the symptom and we diagnose the whole system on the visit. Most Dexter calls involve shared components anyway: the blower, the thermostat, the control board and the ducts serve both heating and cooling.
My Dexter home has a heat pump. Do you work on those?
Yes. Heat pumps share most of their components with central air, and we repair defrost boards, reversing valves, sensors and the backup heat changeover on the systems common in Washtenaw County.
Which HVAC problems are most common in Dexter homes?
In the 1990s–2000s subdivision homes around an 1830s village core around Dexter-Ann Arbor Road corridor: furnace ignitors and flame sensors, AC capacitors, clogged condensate drains, and airflow problems from undersized returns. In newer subdivisions: builder-grade contactors and ECM blower modules around year eight to twelve.
Do you charge a trip fee to Dexter?
We charge the same flat dispatch fee everywhere inside our 20-mile radius, and Dexter is well inside it. That fee covers the diagnosis and is credited toward the repair if you approve it.
Can you repair the system in my Dexter rental?
Yes. We coordinate with the tenant for access, do the repair, and send the invoice and a short written summary to the owner. Many of the landlords we work with in Washtenaw County own several properties and we track the equipment for each.
