Furnace Installation & Replacement in Whitmore Lake, Michigan
Whitmore Lake is about 26 minutes from our shop in Ypsilanti. A new gas furnace sized to your house, vented correctly, commissioned on a combustion analyzer, and installed by the owner. Free estimates, and an honest answer first about whether you need one.
A furnace replacement in Whitmore Lake is a 20-year decision made in a basement, usually under some time pressure because the old one quit in January. Temprasure tries to take the pressure off. If you are without heat, we can set temporary heat and get equipment quickly. If you have time, we walk the house, run the load calculation, look at the chimney, the gas line and the condensate situation, and give you two or three options in writing with one flat price each. Whitmore Lake, MI is well inside our radius, the owner does the install, and the Washtenaw County inspection is part of the job.
Whitmore Lake houses and what that means for furnace installation
Lakefront homes on East Shore Drive and along Whitmore Lake Road are the defining housing type: 1920s–60s cottages that were raised, expanded and insulated over the years, with furnaces in crawlspaces, half-basements or closets, ductwork routed through whatever chase was available, and water heaters wedged under stairs. Many have had a second floor added onto a frame that was built for one, and the ductwork rarely followed. Behind the lake, the older streets off Main Street hold 1940s–70s ranches and bungalows on crawlspaces, some of which started on fuel oil. The 1990s–2010s subdivisions off Barker, Spencer and Nine Mile Roads are colonials on full poured basements with builder-grade 80 percent furnaces, single-stage condensers and bypass humidifiers nearing replacement. Outlying homes on North Territorial and Six Mile are acreage builds and farmhouses on propane and wells. High water tables around both lakes keep below-grade equipment at risk.
The side-wall vent on a condensing furnace needs a good spot, and Whitmore Lake lots do not always offer one. Narrow setbacks between the 1920s–60s lake cottages converted to year-round homes, with 1990s–2010s subdivisions behind them on the older blocks near the Northfield Township Community Center, decks built right over the likely vent location, and bedroom windows on the only clear wall all complicate things. The vent has to stay clear of snow drifts, which in a Washtenaw County winter means well above grade, and it cannot dump exhaust where it will be pulled back into the intake or into a neighbor's window. We walk the outside of the house during the free estimate and show you exactly where the intake and exhaust will terminate before you sign anything.
Heating calls from Whitmore Lake come in two waves: the first real cold night in November and whatever stretch of January the polar vortex decides to visit. Both times we are 26 minutes away with ignitors, flame sensors, pressure switches and inducer motors on the truck. The 1920s–60s lake cottages converted to year-round homes, with 1990s–2010s subdivisions behind them around Barker Road corridor and Nine Mile Road area mostly burn DTE Energy on most of the Washtenaw side natural gas, and the furnaces in them are old enough that a heat exchanger inspection is part of every visit, not an upsell. Near Whitmore Lake itself and out toward North Territorial Road east of US-23, we also see high-efficiency furnaces whose exterior vents ice over in a storm, which looks like a dead furnace and is a ten-minute fix.
Local details we plan around in Whitmore Lake
- Septic serves most of the community, though a sewer system around the lake was added to protect water quality, and condensate routing depends on which a house is on.
- Many winterized cottages have original 60-amp panels or multiple subpanels added over the years, and a new air conditioner usually means an electrician visits first.
- DTE gas serves most of the Northfield side, but some Green Oak addresses are on Consumers Energy and outlying roads on either side run on propane.
- Whitmore Lake and Horseshoe Lake dominate the local weather for the homes around them: summer humidity is high, morning fog is common from May through October, and basements and crawlspaces near the shoreline rarely dry out. The lakes also moderate the first freezes slightly, but by January the open ice and surrounding fields let northwest wind blow across unbroken. Snow runs a bit heavier here than in Ypsilanti because of the slightly higher ground and the township's position farther from the Huron valley.
What Whitmore Lake homeowners call about
Gas bills climbing year over year
An old 80 percent furnace with dirty burners and a tired blower can run well below its nameplate efficiency. A new 96 percent unit cuts the gas side of the DTE bill noticeably.
Repairs three winters in a row
One repair is a repair. Three in three years means the rest of the furnace is close behind, and the money is better spent on new equipment.
Over 20 years old and needing a major part
An inducer, blower motor, control board or gas valve on a furnace from the early 2000s or before often costs enough that a new furnace wins on cost over the next few winters.

Covered on a Whitmore Lake visit
- Honest assessment of whether the existing furnace should be replaced at all
- Gas line sizing check, new drip leg and shutoff valve
- Manufacturer warranty registration and rebate documentation
- New supply plenum and return drop sealed to the existing ductwork
- Written flat-rate options: 80 percent and 96 percent, single-stage, two-stage and variable-speed
- Venting to manufacturer spec: metal flue liner check for 80 percent, PVC intake and exhaust for 96 percent
How a furnace installation call works
Manual J and written options
We calculate the real heating load and give you two or three sized options in writing: typically an 80 percent single-stage, a 96 percent single- or two-stage, and where it fits a variable-speed unit. Each with a flat price.
Installation day
Old furnace removed, new one set and sealed to the ductwork, gas line and venting done to spec, condensate handled, filter rack sized, thermostat wired. Most straightforward replacements finish in one day.
Commissioning on instruments
Gas pressure set with a manometer, blower speed set to the nameplate temperature rise, combustion analysis for CO and efficiency, draft verified, every safety switch tested. We show you the readings.
Reviews from nearby homeowners
★★★★★On June 24 around 3:00 p.m., our A/C stopped working. I called several A/C repair companies and they all told me that it would take from several days to a few weeks to come out. Then I ran across Temprasure. I spoke to Al, and he came out the same day and diagnosed my 26-year-old A/C unit. The bad news is that it could not be repaired. The good news is that I purchased a new A/C unit and his team installed the new unit with no issues. Everything Al said about the installation experience actually occurred as he stated, from the delivery date of the unit to the time it took to install it. Not to mention the prices were more than reasonable.
Furnace Installation questions from Whitmore Lake
Should I get a 96 percent furnace for my Whitmore Lake home?
Often yes, but it depends on your venting and water heater. A condensing furnace saves on DTE Energy gas across a long Washtenaw County winter, but it needs a side-wall PVC vent and may leave the water heater on an oversized chimney. We evaluate both and recommend honestly.
What size furnace do Whitmore Lake homes typically need?
Less than what is usually installed. We run a Manual J on every Whitmore Lake replacement, and the 1920s–60s lake cottages converted to year-round homes, with 1990s–2010s subdivisions behind them common here often need 30 percent fewer BTUs than the furnace that is coming out. Right-sizing is what stops short cycling.
Do Whitmore Lake homeowners qualify for furnace rebates?
Qualifying high-efficiency furnaces are eligible for DTE Energy rebates and for the federal 25C tax credit. During the estimate we identify which options qualify and provide the AHRI certificate and invoice detail you need.
Will you give a second opinion on a furnace replacement quote in Whitmore Lake?
Yes, and we encourage it. We have found condemned furnaces in Washtenaw County that needed a flame sensor. If the heat exchanger really is cracked, we will confirm it so you can replace with confidence, and we will tell you honestly whether the other quote is fair.
Can you replace my Whitmore Lake furnace if I have no heat right now?
Yes. No-heat replacements go to the front of the schedule. We can usually get equipment within a day or two and set up temporary electric heat in the meantime, or make a safe repair to get you through until install day.
