Furnace Faults We See Most in North York
North York is full of postwar bungalows and side splits, many of them now on their second or third furnace. These homes often experience recurring heating problems.
Clogged Furnace Filters
A clogged filter can starve a blower that was already working hard, reducing airflow and causing heating problems.
Dirty Flame Sensors
A flame sensor that needs cleaning every couple of seasons can prevent the furnace from operating reliably.
Worn Inducer Motors
An inducer motor at the end of its life can interrupt the furnace heating cycle.
Tripping Limit Switches
Limit switches can trip because the return air path is too small for the furnace that was installed.
Blocked Condensate Drains
Modern sealed combustion furnaces in newer infill homes can fail because of blocked condensate drains.
Frozen Vent Terminations
Long venting runs can develop problems when intake or exhaust terminations ice over during a cold snap.
Maintenance Is Cheaper Than Repair Here
Most of the faults above give warning. A flame sensor degrades over weeks. A filter blocks gradually. A blower motor draws more current long before it seizes.
An annual tune up catches those while they are still a scheduled part swap in October rather than a cold house in January.
It also keeps the service record that most manufacturer warranties expect you to have if you ever make a claim.
Why Schedule Annual Maintenance?
Regular inspections help identify developing furnace faults before they become unexpected breakdowns.
Cleaning and servicing important components can help maintain reliable heating during North York winters.
Keeping maintenance records also helps document the service history of your heating equipment.
Explore Furnace Maintenance →What the Technician Does on Arrival
The visit starts with the symptom rather than a parts list. Our technicians investigate the furnace before recommending any repair.
The technician reads the control board diagnostics to identify potential furnace faults.
Gas pressure and temperature rise are checked to evaluate furnace operation.
The heat exchanger is inspected as part of the furnace safety assessment.
Safety controls and circuits are tested to identify conditions affecting reliable operation.
Airflow is measured to check for restrictions that could cause overheating or short cycling.
You get the fault, the price, and the choice. Nothing is replaced before you agree to it.
What You Can Check Before You Call
Two things are worth looking at, and both are free.
Check Your Thermostat
Check the thermostat is set to heat, that the target temperature is above the room temperature, and that the batteries are not flat.
Check the Furnace Filter
Pull the filter and hold it up to a light. If you cannot see light through it, that filter alone can be the reason the furnace is overheating and locking out.
