How do I light my furnace pilot light?

Most modern furnaces don't have pilot lights - they use electronic ignition systems instead. If your furnace is more than 15-20 years old and does have a pilot light, this involves working with gas connections and should only be done by a licensed HVAC technician for safety reasons.

For older furnaces with pilot lights, the process typically involves turning off the gas supply, waiting for any residual gas to clear, then following a specific sequence of turning valves and using the igniter button. However, this work requires handling gas lines and combustion systems, which is regulated by TSSA (Technical Standards & Safety Authority) in Ontario. Only licensed G2 or G3 gas technicians are legally permitted to work on gas-burning appliances.

If your furnace won't start, the issue is likely not a pilot light. Modern furnaces have electronic ignition systems that can fail due to dirty flame sensors, faulty ignition modules, or other components. These systems are much more reliable than old pilot lights but require professional diagnosis when they malfunction.

Carbon monoxide safety is critical with any gas furnace work. Improper lighting or adjustment of gas appliances can create dangerous CO conditions. If you smell gas around your furnace, leave your home immediately and call Enbridge at 1-866-763-5427.

Your best next step is to call a licensed HVAC technician to diagnose why your furnace isn't starting. In Ottawa's winter climate, you need reliable heat, and professional service ensures your system operates safely and efficiently. For emergency furnace service in Ottawa, contact a TSSA-licensed contractor who can quickly identify and resolve the issue.
