HVAC Installation & Replacement in Chelsea, Michigan

Chelsea is about 36 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 Washtenaw County, and Chelsea is roughly 36 minutes from our shop on Lakeridge Drive in Ypsilanti. We know the housing here. The 1890s–1920s village homes and 1990s–2010s subdivisions on the edges around M-52 north of town usually need the venting and return air looked at before a new high-efficiency furnace goes in, and the newer builds in 48118 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.

Chelsea houses and what that means for hvac installation

The in-town housing is dominated by 1890s–1940s two-stories, foursquares and bungalows on fieldstone or early block basements with plaster walls and ductwork retrofitted into a house that was designed for a coal furnace or stoves. Flues in these homes are often unlined brick, and we see a lot of 80 percent furnaces that have been venting into a chimney that should have been relined years ago. The post-war ring along McKinley Street and Freer Road is 1950s–70s ranches and capes, some on slabs, with electric baseboard still present in a few. Chelsea Fairways, Heritage Pointe and the other 1990s–2010s subdivisions are colonials and ranches on full basements with builder-grade 80 percent furnaces and single-stage air conditioners that are now hitting replacement age. Outside the city on Werkner, Waterloo and Cavanaugh Lake Roads, we see lakefront cottages that were winterized, farmhouses with multiple additions, and newer acreage homes on propane and well water.

Venting is the second thing we look at hard in Chelsea. 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 1890s–1920s village homes and 1990s–2010s subdivisions on the edges common near the Jiffy Mix plant, 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. Chelsea homes on Consumers Energy in much of the city, DTE Energy on some outlying roads 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 5,500, serving a rural area of roughly 15,000 residents and housing that runs from the 1890s–1920s village homes and 1990s–2010s subdivisions on the edges around Old US-12 corridor to the newer streets near Dexter-Chelsea Road corridor, Chelsea keeps us busy year-round. The equipment is on Consumers Energy for heat and Consumers Energy in much of the city, DTE Energy on some outlying roads for cooling, the basements near the Chelsea Clock Tower 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 25 miles away, we service every brand, and we quote a flat rate before we start.

Local details we plan around in Chelsea

  • Electric service is split between Consumers Energy and DTE depending on the exact address, and homes just outside town may be on one for gas and the other for electric.
  • Outside the city limits, propane furnaces and water heaters are routine, and propane conversions and regulator problems are a normal part of our Chelsea calls.
  • Chelsea is in Consumers Energy gas territory rather than DTE, which matters for rebate programs and for who we call about a meter or service line issue.
  • Chelsea is high and open compared with the river towns to the east, and it gets more wind and a bit more snow than Ypsilanti, with polar vortex nights that run a few degrees colder. The lakes in the Waterloo Recreation Area and around Cavanaugh Lake add summer humidity for the homes closest to them. Heavy tree cover downtown and on the older residential streets shades roofs in July, while the newer subdivisions on the east side have little mature canopy yet.

What Chelsea 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.

Adding central air to a furnace-only house

Pre-war two-stories in Ypsilanti and Ann Arbor and 1950s ranches in Westland often have a furnace and no AC. Adding a coil and condenser is an installation project, and the ductwork needs checking first.

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 Chelsea visit

  • Manufacturer warranty registration in your name
  • Manual D check of existing duct capacity and return sizing
  • Manual J heating and cooling load calculation for the house
  • PVC venting for condensing furnaces or chimney liner evaluation for 80% units
  • Matched evaporator coil and condenser, R-454B or R-32 compliant line set and leak-detection requirements
  • Commissioning report with static pressure, temperature rise and combustion readings

How a hvac installation call works

  1. 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.

  2. 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.

  3. 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.

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.

HVAC Installation questions from Chelsea

Will you tell me if my Chelsea 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.

Who actually does the installation?

Al does, with help as the job requires. The person who measured your Chelsea 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 Chelsea 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.

Can you install in winter?

Yes. Furnaces go in year-round. We install air conditioners in cold weather too, though the final refrigerant charge verification is done when the outdoor temperature allows, and we come back to Chelsea to finish it at no charge.

Do you pull the permit in Chelsea?

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.

Serving every part of Chelsea

A new furnace and air conditioner should be a once-in-twenty-years decision in Chelsea, 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 48118. Estimates are free, Consumers Energy in much of the city, DTE Energy on some outlying roads 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: Heritage Pointe, Old US-12 corridor, Werkner Road area, Dexter-Chelsea Road corridor, M-52 north of town, Freer Road area, and the rest of Chelsea.
