HVAC Installation & Replacement in Dexter, Michigan
Dexter is about 32 minutes from our shop in Ypsilanti. A properly sized furnace and air conditioner, installed by the owner, permitted and inspected, with a free estimate and no pressure to replace what can still be repaired.
Replacing a furnace and air conditioner in Dexter starts with a question we take seriously: does it actually need replacing? Temprasure is an owner-operated shop out of Ypsilanti, about 32 minutes from Dexter, and Al has talked more than a few Washtenaw County homeowners out of a system replacement someone else had already sold them. When the equipment in your 1990s–2000s subdivision homes around an 1830s village core home really is at the end, the estimate is free, the sizing is done with a Manual J calculation on your actual house, and the install is done by the person who quoted it. We pull the permit with Washtenaw County or the local building department, meet the inspector, and commission the system with real readings before we leave Baker Road corridor.
Dexter houses and what that means for hvac installation
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.
Ductwork in Dexter decides whether a new system performs. The sheet-metal trunk and flex branch runs in the 1990s–2000s subdivision homes around an 1830s village core subdivisions around Baker Road corridor were often installed fast and never sealed, and the returns were undersized from the day the house was built. A new variable-speed furnace and a properly charged air conditioner cannot fix a return that starves the blower. Our Manual D check on every Dexter install measures the existing duct capacity against what the new equipment needs. When the ducts are adequate we say so; when they need a larger return, a sealed trunk or a rerouted branch to the room over the garage, we quote it as a separate line so you can see exactly what the ductwork is costing and decide with full information.
Dexter homeowners reach us from Downtown Dexter, Westridge, the blocks around Dexter-Huron Metropark and everywhere in between. The drive from Ypsilanti is roughly 32 minutes, which is close enough that a system failing at dinnertime can usually be seen the same evening. The 1990s–2000s subdivision homes around an 1830s village core common here have the kind of mixed equipment ages that make a whole-system diagnosis worth doing: a newer condenser on an old coil, a furnace from one decade and a thermostat from another. We untangle that, explain it, and fix what actually needs fixing.
Local details we plan around in Dexter
- 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.
- Mechanical permits in the city go through Dexter's building department, while township addresses go through Washtenaw County, and the two have slightly different inspection habits.
- 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 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
Large repair on old equipment
A compressor or coil on a 15-year-old air conditioner, or a control board and blower on a 20-year-old furnace, often costs half of what a new unit does. We show you both numbers and the likely life left in the old one.
Addition or remodel changed the load
A finished basement, a new sunroom or a second-floor addition changes what the system has to heat and cool. The original equipment is now the wrong size, and the ductwork may not reach.
Furnace older than 20 years
Gas furnaces in Michigan basements commonly last 18 to 25 years. Past 20, a failure in the heat exchanger or inducer is a matter of when, and parts for discontinued models get harder to find.

How a hvac installation call works
Free in-home estimate
Al walks the house, measures, looks at the existing equipment, ductwork, venting, gas line and electrical, and asks how the house actually performs. No pressure, no same-day-only pricing.
Installation by the owner
Old system out and refrigerant recovered. New furnace, coil, condenser, line set, venting, gas, condensate and electrical done to code. Deep vacuum, charge by weight, verify by subcooling.
Commissioning and inspection
Static pressure, temperature rise, combustion analysis, airflow and a thermostat walk-through, all recorded. We meet the inspector and you get the paperwork and the warranty registration.
Reviews from nearby homeowners
★★★★★Al was great! I had no A/C on the hottest day of the year and I was able to diagnose it to a failed capacitor. I was calling for the part and no one had stock. I spoke with Al and he was able to help me within an hour — came out, installed and rolling same day. Al is a great guy, highly recommend.
HVAC Installation questions from Dexter
How do you size a system for a 1990s–2000s subdivision homes around an 1830s village core house?
With a Manual J load calculation on the house as it exists now, including any insulation, window or addition work since it was built. Houses in Baker Road corridor almost always need less furnace than the original nameplate.
Do you pull the permit in Dexter?
Yes. Replacement furnaces, condensers and coils require a mechanical permit from Washtenaw County or the local building department, and we handle the permit and the inspection as part of the install.
Which rebates apply in Dexter?
Homes on DTE Energy are typically eligible for utility rebates on qualifying high-efficiency furnaces, air conditioners and heat pumps, plus the federal energy credit on certain tiers. We supply the paperwork and tell you which equipment actually qualifies.
Will the new system fix the hot upstairs in my Dexter colonial?
Only if the ductwork is addressed. The Manual D check on the estimate tells us whether the returns and attic runs can deliver the airflow, and we quote any duct correction separately so you can see it.
How long does a replacement take?
Most furnace and AC replacements in Dexter are a single day. Adding air conditioning to a furnace-only house, new venting or duct corrections can add a day, and we tell you that in the estimate.
