Furnace Repair Calgary

Minor furnace repairs typically run $100–$300. Major repairs involving components like heat exchangers, blower motors, or gas valves range from $500–$1,500+. We start with a comprehensive diagnosis ($149.99 during regular hours) so you know the full cost before any repair begins — no surprises.

We offer 24/7 emergency service and same-day appointments across Calgary and surrounding communities including Airdrie, Cochrane, Okotoks, and Chestermere. In most cases, we can dispatch a technician within hours. Call (587) 792-1476 any time.

Annual maintenance, scheduled before the heating season (September–October), prevents the majority of furnace breakdowns. A well-maintained furnace is less likely to fail in the middle of a cold snap. Our maintenance plans start at $225.99 + GST.

Unusual noises — grinding, whining, or banging — are signs of mechanical wear and should be assessed immediately. Grinding often indicates a failing motor bearing. Banging can signal a delayed ignition or a loose component. Turn the system to fan-only mode and call us — don't ignore furnace noises in a Calgary winter.

Replacement makes sense when your furnace is over 20 years old, when repair costs exceed 50% of replacement value, or when the heat exchanger is cracked. A cracked heat exchanger is a carbon monoxide risk and typically signals end-of-life for the unit. We'll give you an honest assessment — we don't push replacements when a repair is the right call.

AFUE (Annual Fuel Utilization Efficiency) measures how much of the gas your furnace burns actually heats your home. A 96% AFUE furnace converts 96 cents of every gas dollar into heat, while an older 60–80% unit wastes far more. When your furnace is aging and inefficient, the fuel savings from replacement can offset the cost of repeated repairs — we factor this into our honest repair-or-replace recommendation.

Single-stage runs at full output or off. Two-stage adds a lower cruise speed for milder days — quieter, more even heat, and lower bills. Modulating adjusts output continuously for the most consistent comfort and highest efficiency. If a repair leads you toward replacement, we'll recommend the right tier for your home and budget.

Most Calgary homeowners land between $4,500 and $10,000 for a high-efficiency furnace, depending on home size, efficiency tier, and install complexity. Every new install is backed by a 10-year parts & labour warranty. Ask us for an apples-to-apples estimate during your repair diagnosis.

While some furnace problems can be troubleshooted by homeowners — like checking the thermostat settings or replacing a dirty filter — complex issues involving electrical components or gas lines should always be handled by a professional technician to avoid safety hazards and ensure proper repairs.

To prevent future furnace problems, regularly replace furnace filters, schedule annual maintenance inspections, keep vents and registers clear of obstructions, ensure proper airflow by keeping doors and windows sealed, and address any minor issues promptly before they escalate into major repairs.

The duration of a typical furnace repair depends on the nature and complexity of the issue. Minor repairs may take a few hours to complete, while major repairs or replacements may require several days — especially if parts need to be ordered.

Safety concerns when your furnace needs repair include the risk of carbon monoxide leaks, gas leaks, electrical hazards, and fire hazards. It's important to shut off the furnace and contact a qualified technician immediately if you notice any signs of these safety issues.

Look for credentials such as certifications from organizations like NATE (North American Technician Excellence) or ACCA (Air Conditioning Contractors of America), licensing, insurance, and experience working with your specific type and brand of furnace. Reading reviews and asking for references also helps ensure quality service and expertise.
