Winter Furnace Maintenance Checklist for Metro Vancouver

Metro Vancouver winters may not be as extreme as other parts of Canada, but our wet, cold season puts consistent demands on residential heating systems. A proactive fall furnace maintenance checklist ensures you are not scrambling for an emergency HVAC technician during a November cold snap. Here is the complete checklist our certified technicians follow.

Filter and Airflow Checks

• Replace furnace air filter (use MERV 8–11 for best balance of filtration and airflow)
• Inspect all supply and return air vents for blockages or obstructions
• Ensure furniture, rugs, and curtains are not covering any vents
• Check that the area around the furnace is clear of combustibles

Inducer Motor and Combustion System

• Listen for unusual sounds when furnace first starts up (grinding, squealing, rattling)
• Check that the furnace completes a full heat cycle without short cycling
• Inspect the inducer motor housing for moisture, rust, or corrosion
• Verify the pressure switch hose is connected and free of cracks
• Confirm exhaust vent terminations outside are clear of debris, nests, or ice damage

Heat Exchanger and Burners

• Schedule a professional heat exchanger inspection — cracks are a carbon monoxide hazard
• Check burner flames: should be steady blue, not yellow or orange
• Inspect the hot surface igniter or spark igniter for cracks or damage
• Clean burner assembly if accessible (professional service recommended)

Safety Systems

• Test all carbon monoxide detectors and replace batteries
• Test all smoke detectors near the furnace area
• Verify the furnace shutoff switch is clearly labeled and accessible
• Confirm the gas shutoff valve location and operation
• Check that the condensate drain (high-efficiency furnaces) is clear and draining properly

Thermostat and Controls

• Test the thermostat by setting it 5 degrees above room temperature
• Check that the furnace starts promptly and reaches the set temperature
• Replace thermostat batteries if applicable
• Consider upgrading to a smart thermostat for better control and efficiency

When to Call a Professional

Many items on this checklist can be performed by a careful homeowner. However, anything involving the heat exchanger, gas system, electrical components, or the inducer motor itself should be handled by a licensed HVAC technician. If your furnace is 15+ years old, a pre-season professional inspection is especially important.
