Furnace Repair in North Bay: What to Check Before You Call
A furnace that will not heat in North Bay is worth a two-minute check before you book a repair. A.R. Mechanical repairs gas and propane furnaces across North Bay, and several of the most common no-heat calls are a thermostat, a switch, or a clogged filter. If those are fine, stop resetting the unit and call (705) 472-6117. The shop is at 49 Lakeshore Dr., North Bay, ON P1A 2A4. Office hours are Monday to Friday, 8:30 a.m. to 4:30 p.m.
Gas appliances in Ontario have to be worked on by a licensed gas technician. The checks below are homeowner-safe. Anything involving the burners, the gas valve, or the flue is not.
Check the thermostat first
Set the thermostat to Heat, and set the temperature at least 2°C above the room temperature. A blank screen usually means dead batteries. If the fan is set to On, the blower can run without the burners, which feels like cold air from the vents.
Replace the batteries even if the screen is lit. A weak battery is a common North Bay no-heat call on the first cold night.
Check the switch and the breaker
Most furnaces have a switch that looks like a light switch, on the side of the unit or on a nearby joist. It is easy to turn off during a filter change and forget. Confirm it is on.
Then check the breaker panel. A tripped breaker sits between On and Off. Switch it fully off, then on. If it trips again as soon as the furnace starts, leave it off and call. That is an electrical fault, not a filter problem.
Check the filter
A clogged filter is one of the top reasons a furnace short cycles or shuts down in a North Bay winter. Pull the filter and hold it up to a light. If you cannot see light through it, replace it.
A standard 1-inch filter often needs a monthly change during heating season. Thicker media filters last longer. Put the new filter in with the airflow arrow pointing toward the furnace. A backward filter restricts air the same way a dirty one does.
After a filter change, wait a few minutes and try the thermostat again. If the furnace starts and stays on, you may not need a service call.
Check the intake and exhaust outside
High-efficiency furnaces in North Bay use plastic intake and exhaust pipes, usually on a side wall. Snow, ice, or a drifted bank can block them after a storm. Clear snow back from both pipes. Do not block them with a cover.
If the pipes are clear and the furnace still will not start, leave them alone. Do not open the furnace and look for the fault yourself.
What not to do
Do not keep resetting a furnace that will not stay lit. Two or three resets after a filter check is enough. Repeated resetting can flood the burners or hide a failed igniter, a dirty flame sensor, or a venting problem.
Do not spray cleaners into the burners. Do not bypass a safety switch. Do not remove a TSSA red tag or relight a red-tagged furnace. A red tag means a licensed technician has shut the appliance off because it is unsafe.
If you smell gas, leave the house and call the gas utility from outside. If a carbon monoxide alarm sounds, get everyone out and call 911 from outside. Do not restart the furnace until it has been inspected.
If the checks fail, book the repair
Once the thermostat, switch, breaker, filter, and outdoor pipes are ruled out, the usual remaining faults are a failed hot-surface igniter, a dirty flame sensor, a limit switch, or a control board. Those are technician jobs. Have the furnace brand ready. The sticker is inside the upper door.
A.R. Mechanical diagnoses first and quotes major parts before they are replaced. Igniters and flame sensors are often repaired on the same visit. Motors, boards, and heat exchangers are quoted. Most repairs in Ontario land in a few hundred dollars. The high end is a cracked heat exchanger, which usually means replacement.
Repair is the right call if the furnace is under about 12 years old and this is one failed part. Replace it if it is 15 to 20 years old, the heat exchanger is cracked, or the repair approaches half the cost of a new high-efficiency furnace. A fall tune-up through the Membership Program is what keeps most of these calls from landing in January.

What should I check before calling for furnace repair in North Bay?
Check the thermostat is set to Heat, the furnace switch and breaker are on, the filter is clean, and the outdoor intake and exhaust pipes are clear of snow. If it still will not heat, call a licensed technician.
Why does my furnace blow cold air?
Cold air is usually an ignition or flame-sensor fault, a thermostat left on Fan, or a furnace that has locked out. Check the filter and the thermostat, then shut it off and book service if it continues.
