Furnace Repair in Gravenhurst

When your furnace stops working in the middle of a Muskoka winter, you need a heating contractor who answers the phone, shows up, and fixes the real problem. Bridlewood Mechanical provides furnace repair in Gravenhurst, Bracebridge, and across Muskoka for natural gas and propane furnaces of every major brand. We're a family-owned HVAC company that has served this community since 1975.

Furnace Repairs and Installations Done Right

Our licensed gas technicians diagnose and repair:

• Furnaces that won't turn on or won't ignite
• Blowing cold air or not enough heat
• Short cycling, where the furnace turns on and off every few minutes
• Ignitor and flame sensor failures, the most common winter no-heat calls
• Blower motor, capacitor, and belt problems
• Inducer motor and pressure switch faults
• Control board and limit switch failures
• Thermostat and wiring issues, including smart thermostats
• Condensate drain clogs on high-efficiency furnaces
• Strange noises: banging, squealing, rattling, or humming
• Gas valve and burner issues on natural gas and propane units

We carry the most common parts on our trucks, so many repairs are completed on the first visit.

Home Heating Emergencies

A furnace failure in January is urgent, especially at a cottage or when pipes can freeze. If your home has no heat, we'll prioritize getting it back safely and quickly. Please call right away and leave the property if you smell gas or your carbon monoxide alarm is sounding.

What to Check Before You Call

A few quick checks can sometimes save a service call:

1. Thermostat. Is it set to "Heat," set above room temperature, and are the batteries fresh?
2. Breaker and furnace switch. Make sure the furnace power switch (often near the unit, like a light switch) is on and the breaker hasn't tripped.
3. Furnace filter. A badly clogged filter can make the furnace overheat and shut down.
4. Furnace door. The blower door must be fully closed or a safety switch keeps the furnace off.
5. Vents outside. On high-efficiency furnaces, snow or ice blocking the PVC intake or exhaust pipes will shut the furnace down.

If none of these solve it, it's time for a professional furnace repair specialist.

Repair or Replace?

Our technicians give you a straight answer. If a repair makes sense, we'll fix it. If your furnace is 15+ years old, has a cracked heat exchanger, or keeps breaking down, we'll explain your options, including a high-efficiency furnace or a heat pump system. See Furnace Replacement.

Furnace Maintenance Prevents Most Breakdowns

Most furnace repairs we see could have been caught with an annual tune-up. A yearly inspection includes cleaning the burners and flame sensor, checking the heat exchanger, testing safety controls, measuring gas pressure and combustion, and testing for carbon monoxide.

Furnace Repair FAQs

What is the average cost to replace a furnace in Ontario? It depends on the furnace's efficiency, size, and venting requirements. We provide free, written replacement quotes, and we'll always tell you if a repair is the smarter choice.

What is the most expensive part of a furnace to replace? The heat exchanger, followed by the control board, blower motor, and inducer motor. When a heat exchanger fails on an older furnace, replacement is usually the better option.

What does a furnace inspection include? Cleaning and inspecting the burners, flame sensor, and ignitor; checking the heat exchanger for cracks; testing safety and limit switches; measuring gas pressure, temperature rise, and combustion; checking the blower and electrical connections; and carbon monoxide testing.

Do you repair propane furnaces? Yes. Our technicians are licensed for both natural gas and propane, which is common at Muskoka cottages and rural properties.

Why is my furnace blowing cold air? Common causes are a dirty flame sensor, a failed ignitor, a clogged filter causing the high-limit switch to trip, a blocked condensate line, or a thermostat fan setting of "On" instead of "Auto."
