Furnace Repair for Calgary Homes
When a furnace stops heating, starts short cycling, makes new noises, or shows an error code, Alberta Mountain Air can diagnose the system and explain the repair options before approved work begins. We check the whole heating sequence so the recommendation is based on the furnace, controls, airflow, venting, and safety condition.
What this service includes
- No-heat and intermittent-heat diagnostics
- Igniter, flame sensor, inducer, blower, gas valve, and control checks
- Filter, return-air, and airflow review
- Venting and condensate review where applicable
- Thermostat and safety-control testing
- Repair vs replacement guidance for older systems
When to Book Furnace Repair
| Situation | Why it matters | Next step |
|---|---|---|
| Furnace will not start | The issue may be ignition, thermostat, gas supply, safety controls, or electrical. | Book a furnace diagnostic. |
| Furnace starts then shuts off | Short cycling can point to airflow, flame sensing, limit, venting, or control problems. | Schedule repair service. |
| Furnace blowing cold air | Could be a thermostat set to fan on, a dirty filter restricting heat, a failed ignition mid-cycle, or a safety limit switch shutting the burners off. | Call for a same-day inspection. |
| New smells, noises, or error codes | Changes in operation should be checked before a small issue becomes a no-heat call. | Call for troubleshooting. |
Frequently Asked Questions
What should I check before calling for furnace repair?
Check that the thermostat is set to heat, the furnace switch and breaker are on, the filter is not blocked, and the intake or exhaust vents are clear. If the furnace still will not run normally, book a diagnostic.
Is my furnace worth repairing?
It depends on the furnace age, safety condition, repair cost, warranty status, and repair history. We explain the finding and compare repair with replacement when that conversation is useful.
Do you repair all furnace brands?
Yes. Alberta Mountain Air services common furnace brands used in Calgary homes, including Lennox and many other major brands.
Can you fix my furnace today?
Same-day furnace repair is available most days in Calgary and nearby communities, depending on schedule, weather, and parts availability. Calling earlier in the day gives the best chance of a faster appointment.
What credentials does your team have?
Our team includes Journeyman Sheet Metal Workers, Journeyman Gas Fitters, Journeyman Refrigeration Mechanics, and a Master Electrician.
Is it safe to run a furnace that is making strange noises?
Do not ignore new furnace noises, burning smells, or error codes. Shut the system down if you are concerned and call for troubleshooting before a small issue becomes a safety problem.
