Older furnaces commonly run at 70–80% AFUE — meaning 20–30 cents of every heating dollar escapes unused. Modern high-efficiency systems reach 95–98% AFUE.

What Your Neighbors Are Saying

Based on verified customer reviews.

★★★★★

“Thank you for sending Dave! He was great – quickly solving our furnace problem in a timely manner at a very reasonable cost – 25% of what the last guy charged. Now our furnace is working properly. My daughter has found a heating service provider in this area of home maintenance she can trust === in your company. See you guys next time — for sure!”

“The day after we moved into our new home WM Schmidt efficiently installed our new A/C unit. An electrical contractor had not put the required wiring in for the internal component, but instead of having to call out an electrician and come back another day, he sourced someone to come and fix it over the lunch hour so the job could be completed in one day. Fast and friendly, knowledgeable service!”

“I used W M Schmidt to do my first furnace inspection since I purchased a new home and they were amazing. The service technician was highly professional and efficient and took the time to explain everything to me during the inspection. The service charge was extremely reasonable. I also found that the company overall is very well organized and prompt. I phoned them on a Friday and they were able to do the inspection on the following Monday. I highly recommend this company.”

  • Yellow or flickering pilot flame (should be blue)
  • Frequent repairs over the past two years
  • System is 15+ years old

COMMON QUESTIONS

Everything You’re Wondering About

· Repair if the furnace is under 12–15 years old and the issue is minor (ignitor, blower, thermostat).

· Replace if it’s 15–20+ years old or breaking down frequently.

· Repair if the cost is under ~30–40% of a new unit; otherwise, replacement is usually smarter.

· Replace if you notice rising energy bills, uneven heating, or strange noises.

· Always replace if the heat exchanger is cracked—this is a safety issue.

A typical furnace replacement is pretty quick:

· Standard swap (same location, similar unit): done in a day

· More complex installs: 1–2 days (if ductwork, venting, or gas line changes are needed)

· Add-ons (AC, humidifier, filtration, etc.): can push it into a full day or longer

· Electrical upgrades or code violation fixes: may add extra time

· Bottom line: most homeowners have heat restored the same day

The common brands we install are:

· GE (General Electric)

· Airease (manufactured by Lennox)

· Comfortmaker (manufactured by Carrier ICP)

10 year warranty includes:

· Parts coverage: Most manufacturers cover key components like the heat exchanger, blower motor, control board, and ignitor for 10 years.

· Heat exchanger: Often has an extended or lifetime warranty (separate from the 10-year parts).

· Labour is usually NOT included: You’ll still pay for service/installation unless you purchased an additional labour warranty.

· Registration required: Many brands require you to register the furnace within ~60–90 days to get the full 10-year coverage (otherwise it may default to 5 years).

· Conditions apply: Regular maintenance is often required, and the warranty may not transfer fully if you sell your home.
