HVAC Installation & Replacement in Dundee, Michigan
Dundee 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.
Temprasure installs furnaces, air conditioners and heat pumps across Monroe County, and Dundee is roughly 32 minutes from our shop on Lakeridge Drive in Ypsilanti. We know the housing here. The 1860s–1930s village houses with 1990s–2010s subdivisions on the edges around Cabela Boulevard commercial area usually need the venting and return air looked at before a new high-efficiency furnace goes in, and the newer builds in 48131 usually have ductwork that was never sealed and a condenser pad that has settled. A new system from us accounts for those things in the estimate instead of discovering them on install day, and the estimate is free, written, and good for a long time.
Dundee houses and what that means for hvac installation
Dundee's housing has two distinct halves. The village core along Riley, Tecumseh and Monroe Streets is 1860s to 1930s frame and brick houses on Michigan basements or stone foundations, with retrofitted ductwork and, in a few cases, a boiler still in service. These houses have furnaces in low, damp basements near the river, water heaters that have been through a flood or two, and central air added in the 90s with a condenser on the side of the house. The post-2000 subdivisions along Ann Arbor Road and on the west side of US-23 are colonials and ranches on poured basements with builder-grade 80 percent furnaces and 13 SEER condensers that are now 15 to 25 years old and starting to fail. Outside the village limits, farmhouses and acreage homes on propane are common. Water in the village is municipal, but township addresses are on wells, and the well water in this part of Monroe County is hard enough to be a real factor in water heater and humidifier life.
Venting is the second thing we look at hard in Dundee. A high-efficiency condensing furnace vents through the side wall in PVC, which frees up the masonry chimney that an older 80% furnace shared with the water heater. In the 1860s–1930s village houses with 1990s–2010s subdivisions on the edges common near Cabela's at US-23 and M-50, that leaves a 40-gallon atmospheric water heater alone on a chimney that is now too large for it, and the flue gases can condense and eat the liner. We address that on the estimate, either with a chimney liner sized for the water heater or by talking through a power-vent water heater at the same time. Dundee homes on DTE Energy gas also get the gas line pressure-tested and the drip leg and shutoff brought up to current code as part of the install.
With about 4,000 in the village, with the township adding a few thousand more residents and housing that runs from the 1860s–1930s village houses with 1990s–2010s subdivisions on the edges around the Riley Street historic blocks to the newer streets near Downtown Dundee on Main and Monroe Streets, Dundee keeps us busy year-round. The equipment is on DTE Energy for heat and DTE Energy for cooling, the basements near the Old Mill Museum on the River Raisin are prone to the same moisture issues as the rest of Monroe County, and the ductwork in a lot of these houses was never sized for the air conditioner that was bolted on later. We are 22 miles away, we service every brand, and we quote a flat rate before we start.
Local details we plan around in Dundee
- River Raisin flooding has reached basements in the downtown blocks more than once, and we set replacement equipment on raised pads and recommend flood-aware placement.
- The 2000s subdivisions were built with flex-duct branch runs that sag and restrict airflow, which is the usual cause of weak upstairs airflow here.
- Well water on the township side is hard, so water heater sediment flushing and humidifier pad replacement come up more often than in the Detroit-system suburbs.
- Dundee is flat, open Monroe County farmland with the River Raisin running through the middle of the village, and the millpond and river bottoms keep the downtown blocks humid and fog-prone in spring and fall. The open fields around the village let winter wind run unchecked, and Dundee is close enough to Lake Erie to pick up more cloud cover and occasional lake-enhanced snow than Ypsilanti sees. Summer afternoons are humid with dew points regularly near 70.
What Dundee homeowners call about
R-22 system with a refrigerant leak
Reclaimed R-22 is scarce and expensive, and any system still using it predates 2010. Chasing a leak on one is money spent on a system near the end of its life.
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.
Cracked heat exchanger
Once a furnace heat exchanger has a confirmed crack, it is done. Carbon monoxide can enter the air stream, and no honest contractor will keep it running. This is the one failure that is a replacement, not a repair.

Covered on a Dundee visit
- Mechanical permit pulled and inspection scheduled with the county or municipality
- Electrical disconnect, whip and breaker verification for the condenser
- Nitrogen-purged brazing, deep vacuum and refrigerant charge by weight verified with subcooling
- Manufacturer warranty registration in your name
- New furnace set on a pad with vibration isolation, sealed plenum connections and proper condensate trap
- Manual D check of existing duct capacity and return sizing
How a hvac installation call works
Manual J and D sizing
A real load calculation on your house, not a rule of thumb from the old nameplate. We check that the existing ducts can carry the airflow the new system needs and tell you if they cannot.
Written options, explained
Two or three equipment configurations in writing, with the efficiency, staging and rebate picture for each, and our honest recommendation of which one fits your house and budget.
Permit and scheduling
We pull the mechanical permit with the county or city, order the equipment, and set an install date. Most furnace and AC replacements are done in one day.
Reviews from nearby homeowners
★★★★★Al and his team are great. Our furnace stopped working on New Year's Eve. I called 10 HVAC shops and no one would come out except Al. He helped determine our problem and within a week I had a new furnace that was covered by my home insurance. I had a few problems post-install and the Temprasure team came over immediately on the weekend to fix it. Great company. Highly recommend!!
HVAC Installation questions from Dundee
Will you tell me if my Dundee system does not need replacing?
Yes. That is the first question we answer on the visit. If a repair buys several more years, we quote the repair instead and encourage you to get a second opinion on anything that sounds like a replacement.
How long does a replacement take?
Most furnace and AC replacements in Dundee 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.
Who actually does the installation?
Al does, with help as the job requires. The person who measured your Dundee house and wrote the estimate is the person setting the furnace and charging the system.
Will the new system fix the hot upstairs in my Dundee 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.
Do you pull the permit in Dundee?
Yes. Replacement furnaces, condensers and coils require a mechanical permit from Monroe County or the local building department, and we handle the permit and the inspection as part of the install.
Serving every part of Dundee
A new furnace and air conditioner should be a once-in-twenty-years decision in Dundee, made with good information rather than under pressure on a cold night. Text or call us, send a photo of the equipment label and a description of what the system is doing, and we will tell you what we think before anyone drives out to 48131. Estimates are free, DTE Energy rebate paperwork is handled, and there is no pressure to decide on the spot. Reach out when you are ready.
Neighborhoods and areas we run to regularly: the River Raisin waterfront, Ann Arbor Road north of the village, Downtown Dundee on Main and Monroe Streets, the Toledo Street neighborhoods, the US-23 and M-50 interchange, Tecumseh Street, and the rest of Dundee.
