Furnace Repair in Calgary

When you call during business hours, we can usually schedule a technician the same day in most Calgary areas. Our trucks carry common furnace parts such as igniters, flame sensors and capacitors, so many repairs are completed on the first visit.

This is called short cycling. Common causes are a dirty filter, an overheating limit switch, a dirty flame sensor or a furnace that is too big for the home. Short cycling wears parts out faster, so book a diagnostic if it keeps happening.

Most modern furnaces have a control board with a light that flashes an error code. The pattern points to the fault, such as a pressure switch or ignition problem. Note the pattern and mention it when you book. It helps your technician come prepared.

A bang when the furnace starts often means the burners are lighting late. Squealing, humming or grinding usually points to a blower or inducer motor problem. If the noise is loud or new, turn the furnace off and book a repair.

If your furnace is over 15 years old, or the repair would cost a large share of a new one, replacement may make more sense. We show you both options. See furnace installation and replacement for details.

Watch for no heat, cold air from the vents, uneven heating, new noises or smells, short cycling and rising gas bills. Booking early can stop a small problem from becoming a no-heat call on a cold night.

Yes. We repair all major makes and models, including Lennox, Goodman, Carrier, Armstrong Air, York and Trane.

Change your filter regularly and book a yearly furnace tune-up. Many breakdowns start with a worn igniter, a dirty flame sensor or a weak motor that a tune-up would catch.

First check that the thermostat is set to Heat, not just Fan On, and that the filter is not clogged. If it still blows cold, the burners are likely not lighting, often because of a failed igniter, a dirty flame sensor, a pressure switch fault or a frozen intake or exhaust pipe. These are common Calgary winter repairs we fix on the first visit in most cases.
