Common problems
Furnace problems we fix most often in Calgary
These are the furnace calls we get most from Calgary homeowners, and what each symptom usually points to.
No heat at all
Often an ignition failure, a tripped safety switch, a badly clogged filter, or a thermostat that is not calling for heat. We test each one in order instead of guessing.
Furnace will not turn on
A dead thermostat, a tripped breaker, an open door switch on the blower compartment, or a failed control board can each stop a furnace from starting.
Short cycling
A furnace that starts and stops every few minutes is usually overheating from poor airflow, has a dirty flame sensor, or is oversized for the house.
Blowing cold air
Cold air from the vents can mean the burners are not lighting, the flame sensor is shutting them down, or the fan is set to run on its own.
Strange noises or smells
Banging at start-up, squealing from the blower, or a burning smell that lasts past the first run of the season are worth a look before they turn into a breakdown.
Rising gas bills
If your bills climb without a change in how you use the house, the furnace may be running longer to make the same heat because of airflow or combustion problems.
What a repair visit includes
How we diagnose and repair your furnace
Safety checks first
We check for gas leaks, venting problems, and carbon monoxide concerns before anything else. A furnace that runs is not always a furnace that runs safely.
Diagnosis, not guesswork
We test the ignition sequence, flame sensor, pressure and limit switches, inducer and blower motors, and the thermostat signal to find the actual fault.
Common parts on the truck
Our trucks carry parts for the most common failures, including igniters, flame sensors, pressure switches, capacitors, and drain lines, so many repairs can be finished on the first visit.
The cost explained before work begins
We explain what failed, what the repair involves, and what it will cost before we start. Emergency and after-hours service may be priced differently from standard scheduled work, so ask about the rate when you call.
Repair or replace
Should you repair or replace your furnace?
We lean toward repair when repair makes sense, and we tell you plainly when it does not. These are the factors we walk you through.
Repair usually makes sense when
- The furnace is under about 15 years old
- The fault is a single part, such as an igniter, flame sensor, or inducer motor
- It has been maintained and has not needed repeated repairs
- The heat exchanger checks out with no cracks or signs of failure
Replacement is worth discussing when
- The furnace is approaching 15 to 20 years, the typical service life
- Repairs are becoming frequent or expensive
- The heat exchanger is cracked or failing
- Rooms heat unevenly or gas bills keep climbing
- You are planning other upgrades, such as central air or a heat pump
When replacement is the better call, we install new high-efficiency furnaces and can walk you through options such as the Navien NPF hydro-furnace, which heats the home and supplies hot water from one unit. See two recent furnace installations in Calgary for how we finish the job.
Furnace maintenance
Furnace maintenance that prevents winter breakdowns
Most furnace failures that turn into emergencies were preventable. A pre-season tune-up and a few habits at home go a long way.
What you can do at home
- Replace the filter every 60 to 90 days, and check it monthly during the coldest weeks
- Keep the intake and exhaust pipes outside clear of snow and ice
- Keep supply and return vents open and free of furniture
- Test your carbon monoxide alarms and replace their batteries every year
What a tune-up covers
- Heat exchanger inspection for cracks
- Flame sensor cleaning and igniter testing
- Gas pressure and burner check
- Venting and flue inspection
- Safety control and limit switch testing

FAQ
Furnace repair FAQs for Calgary homeowners
How much does furnace repair cost in Calgary?
It depends on which part failed, the age and type of furnace, and the time of the call, so we explain the cost once we know what is wrong. Emergency and after-hours service may be priced differently from standard scheduled work, so ask about the rate when you call. Your technician will explain what the repair involves and what it will cost.
How long does a furnace last?
Most furnaces have a reliable service life of about 15 to 20 years. Age alone is not a reason to replace one, but a furnace in that range that needs a major repair is worth a replacement conversation.
How often should a furnace be serviced?
Once a year, ideally in the fall before heating season. Check the filter monthly in winter and replace it every 60 to 90 days.
Do you repair all furnace brands?
Yes. We service and repair furnaces on all makes and models, and we install new high-efficiency furnaces when replacement makes more sense.
My furnace runs but blows cold air. What should I check?
Make sure the thermostat is set to heat and the fan is on auto, then check the filter. If the burners still do not light, or shut off after a few seconds, call us rather than resetting the furnace over and over.
Is a furnace that will not start an emergency?
In a Calgary winter it can be, especially below about minus 10 degrees. A gas smell or a carbon monoxide alarm means leave the home first and call 911. See emergency heating for the full guide.
