Furnace Installation & Replacement in Northville, Michigan

Northville is about 28 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 Northville 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. Northville, MI is well inside our radius, the owner does the install, and the Wayne County inspection is part of the job.

Northville houses and what that means for furnace installation

Northville's housing splits sharply between the historic city and the township subdivisions. The Cady Street district and the blocks off Main and Center are 1870s to 1920s two-stories and Queen Annes with Michigan basements, fieldstone walls and low ceilings, where the ductwork was retrofitted and the furnace location is usually a compromise. Some of these houses still have steam or hot-water radiators fed by boilers that have been rebuilt more than once. The Beal Town and Randolph Street blocks have 1920s to 40s bungalows with small basements and finished attics. Beyond the city, the township's 1970s colonials and quad-levels in Northville Hills and Highland Lakes are on block basements with original trunk-and-branch duct, and the 1990s to 2010s subdivisions off Seven Mile, Six Mile and Beck Road are large colonials on poured basements with two systems, zoning and, often, a furnace in the attic serving the second floor. Water heaters in the newer houses are 50-gallon or power-vented gas units, and 75-gallon tanks are not unusual.

Gas service and electrical both get checked on a Northville furnace replacement. Older homes near the Northville Downs redevelopment site occasionally have a gas line that was sized for a furnace and a range in the 1950s and has since picked up a water heater, a dryer and a grill, and a new furnace at the end of that run can be starved on a cold night when everything fires at once. On the electrical side, a modern furnace with an ECM blower wants a clean dedicated circuit, and we see shared circuits and ungrounded outlets at the furnace in Northville, MI basements more often than you would expect. Both get evaluated on the estimate and quoted up front if they need correction.

We run a lot of winter miles in Northville, and most of them end in a basement under one of the Victorian-era two-stories downtown and 1970s–2010s colonials in the surrounding subdivisions that make up its streets near Northville Hills, Edenderry and Eight Mile Road neighborhoods. DTE Energy service reaches nearly every home here, so the equipment is familiar: 80 percent and 90-plus percent gas furnaces, a few boilers near Ford Field Park, and the occasional propane furnace at the rural edge. What differs house to house is the ductwork and the wiring, and that is where a careful technician earns the dispatch fee. We arrive from Ypsilanti in about 28 minutes, any hour, at the same flat rate.

Local details we plan around in Northville

  • The city sits in two counties and permits run through the city building department regardless, but township addresses just outside the limits go through Northville Township.
  • Attic furnaces in the newer two-system colonials are prone to frozen condensate lines and ignored filters, and we inspect them on every maintenance visit.
  • Fieldstone Michigan basements on Cady Street and the surrounding blocks are low and damp, so equipment goes on raised pads and condensate routing takes planning.
  • Northville is hilly for Southeast Michigan, sitting on the moraine ridge that runs through Maybury State Park, and the elevation plus heavy tree cover keeps the historic district a few degrees cooler on summer afternoons than the flat suburbs to the south. The Middle Rouge and Johnson Creek run through the downtown valley, and basements along them carry moisture. The open high ground along Seven and Eight Mile takes winter wind with little obstruction.

What Northville 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.

Short cycling that no repair fixes

A furnace badly oversized for the house will short cycle forever, wearing out ignitors and stressing the exchanger. Right-sizing on replacement fixes it permanently.

Covered on a Northville visit

  • Gas line sizing check, new drip leg and shutoff valve
  • Water heater vent evaluation when a chimney is orphaned by a condensing furnace
  • Venting to manufacturer spec: metal flue liner check for 80 percent, PVC intake and exhaust for 96 percent
  • Thermostat matched to the furnace staging, programmed and tested
  • Properly sized filter rack for a 4-inch media filter where space allows
  • Condensate trap, neutralizer where required, and freeze-protected drain routing

How a furnace installation call works

  1. Free estimate and honest assessment

    Al inspects the existing furnace and heat exchanger, the ductwork, the venting, the gas line and the water heater's vent, measures the house, and tells you first whether replacement is actually warranted.

  2. 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.

  3. 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 Northville

Do Northville 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.

What size furnace do Northville homes typically need?

Less than what is usually installed. We run a Manual J on every Northville replacement, and the Victorian-era two-stories downtown and 1970s–2010s colonials in the surrounding subdivisions common here often need 30 percent fewer BTUs than the furnace that is coming out. Right-sizing is what stops short cycling.

Should I get a 96 percent furnace for my Northville home?

Often yes, but it depends on your venting and water heater. A condensing furnace saves on DTE Energy gas across a long Wayne 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.

Can you replace my Northville 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.

How long does a furnace replacement take in Northville?

A like-for-like replacement is usually one day. Converting to high-efficiency venting, lining a chimney for the water heater, or doing the AC at the same time can run into a second day. We tell you the schedule up front.

Serving every part of Northville

If the furnace in your Northville home is on its last winter, get the replacement conversation started on your schedule rather than during a polar vortex when every installer in the area is booked. A fall estimate means a furnace sized with a Manual J, vented correctly and chosen without pressure.
