What is the cost to repair a gas fireplace that will not light in Calgary?

Gas fireplace repair costs in Calgary typically range from $200-$600 for common ignition problems, with most service calls starting at $150-$200 for diagnosis plus parts and additional labor.

The most frequent causes of gas fireplaces that won't light include a faulty thermocouple ($80-$150 to replace), dirty or damaged pilot assembly ($120-$200), failed ignition control module ($200-$400), or clogged burner orifices ($100-$180 for cleaning and adjustment). If the issue is simply a dead battery in a battery-powered ignition system, that's a $20-$40 fix including the service call.

More complex problems can increase costs significantly. A failed gas valve runs $300-$500 including labor, while control board replacement ranges from $400-$700. If the heat exchanger has developed cracks — a serious safety issue — repair costs jump to $800-$1,500, though replacement is often more economical at that point. Carbon monoxide sensors and safety switches typically cost $150-$300 to replace.

Calgary's extreme winter conditions contribute to specific fireplace problems. After months of heavy use during our long heating season (October through April), components like thermocouples and pilot assemblies wear out faster than in milder climates. Chinook wind events can also affect chimney draft and cause pilot lights to blow out repeatedly, potentially damaging ignition components over time. Many Calgary homeowners discover ignition problems right at the start of heating season when they first try to light their fireplace after summer.

Annual maintenance prevents most ignition failures and costs $150-$250 in Calgary — significantly less than emergency repairs. During a service call, technicians clean the pilot assembly, test the thermocouple, inspect gas connections, and verify proper combustion air flow. Given that Calgary fireplaces see 5-6 months of regular use, this annual service typically pays for itself by preventing one major repair.

Safety considerations are critical with any gas fireplace that won't light. If you smell gas, hear hissing sounds, or suspect a gas leak, shut off the gas supply immediately and call ATCO Gas emergency line at 1-800-511-3447. Never attempt DIY repairs on gas components — all gas appliance work in Alberta must be performed by licensed gas fitters with proper permits and Safety Codes Officer inspection.

Get a proper diagnosis before authorizing expensive repairs. Reputable Calgary fireplace technicians will diagnose the problem first (usually $150-$200) and provide a detailed estimate before proceeding. If repair costs exceed 60-70% of a new fireplace's price, replacement often makes more financial sense, especially for units over 15-20 years old.
