Common Furnace Problems Calgary Homeowners Face
Extreme temperature swings, older homes, and heavy winter usage can put serious strain on a furnace. Some of the most common furnace repair issues in Calgary include:

No heat or insufficient heat: Furnace running but blowing cool air or not reaching the thermostat setting.
Furnace not turning on: System fails to start, short cycles, or shuts down unexpectedly.
Strange noises: Banging, rattling, squealing, or grinding sounds from the furnace cabinet or blower.
Frequent cycling: Furnace turns on and off repeatedly in short bursts.
Weak airflow: Some rooms stay cold, vents blow gently, or airflow is uneven throughout the home.
Burnt or unusual odours: Smell of burning dust when starting, or persistent metallic, chemical, or gas-like odours.
Higher energy bills: Noticeable spike in gas or power usage without any change in your routine.
Yellow or flickering pilot flame (on older units): Instead of a steady blue flame, which may indicate combustion or safety issues.

If any of these symptoms sound familiar, it is important to schedule a furnace inspection and repair as soon as possible to prevent further damage and potential safety risks.

Signs You Need Furnace Repair Instead of Waiting

In Calgary’s climate, delaying furnace repair can turn a small, inexpensive fix into a major breakdown. Schedule furnace repair in Calgary promptly if you notice:

Hot and cold spots or rooms that never feel comfortable
Furnace running longer than usual to maintain temperature
Unusual sounds starting or getting progressively worse
Visible rust, corrosion, or water around the furnace
Frequent thermostat adjustments without real improvement

Any sign of a gas leak or carbon monoxide issue is an emergency. Leave the home immediately and contact emergency services before calling for HVAC support.

Furnace Repair vs. Replacement: What Is Right for Your Calgary Home?
Sometimes a furnace can be repaired; other times replacement is the better long-term solution. Common factors considered include:

Age of the furnace: Most furnaces last around 15–20 years with proper care. Older units may cost more to keep fixing than they are worth.
Frequency of repairs: Recurring breakdowns and repeated service calls are strong indicators that replacement may be more cost-effective.
Energy efficiency: Newer high-efficiency models can significantly reduce heating costs, especially in a cold climate like Calgary.
Safety concerns: A cracked heat exchanger or ongoing combustion issues often make replacement the safest option.

Shift Heating & Cooling Services Ltd. can provide an honest assessment and cost comparison between furnace repair and replacement to help you make a confident decision.
Prevent Future Breakdowns with Regular Furnace Maintenance
Preventive furnace maintenance is one of the most effective ways to reduce repairs and extend the lifespan of your system. Recommended annual maintenance before the heating season typically includes:

Cleaning or replacing furnace filters
Inspecting burners, flame sensors, and ignitors
Checking blower motor and fan operation
Inspecting venting and duct connections
Testing safety controls and carbon monoxide risk
Verifying thermostat operation and system performance

Scheduling yearly furnace maintenance with Shift Heating & Cooling Services Ltd. can help catch small issues before they become emergency repairs.
