Create an HVAC Emergency Kit

Every Vancouver home should have an HVAC emergency kit ready before a failure occurs. Essential items include: the phone numbers of your gas utility emergency line, your preferred HVAC service provider, and a trusted electrician written on paper (phones die, batteries fail), spare furnace filters in the correct size, a portable electric space heater certified for indoor use, fresh batteries for your thermostat, a flashlight with spare batteries to inspect your mechanical room, and the manufacturer's manual for your furnace, boiler, or heat pump with error code definitions.

Know Your Equipment Before an Emergency

Take 10 minutes today to locate and understand your equipment. Find the furnace or boiler power switch and verify it works. Locate the gas shut-off valve and ensure it operates freely. Write down your furnace or boiler model number and serial number — this information helps technicians bring the correct parts. Photograph the equipment nameplate with your phone. Note any error code display on your thermostat or equipment. Know whether your thermostat is battery-powered or hardwired, and keep spare batteries on hand if battery-powered.

Who to Call and When

For gas emergencies including gas odour, suspected carbon monoxide, or CO alarm activation, call 911 or your gas utility emergency line from outside the building. For furnace, boiler, or heat pump failure without gas-related safety concerns, call your HVAC service provider. Have phone numbers for backup service providers in case your primary is unavailable. For electrical issues such as tripped breakers that will not reset, call a licensed electrician. In a rental property, know your landlord's emergency maintenance procedure and after-hours contact.

Temporary Heating Options

If your primary heating system fails during cold weather and service is delayed: use electric space heaters to keep occupied rooms warm, close doors to unused rooms to concentrate heat in occupied spaces, open curtains on sunny windows during the day and close them at night, dress in layers including a hat indoors, use electric blankets or heating pads while awake, and avoid using ovens, gas ranges, or outdoor heaters indoors — these produce carbon monoxide and are deadly. A single 1,500-watt electric space heater can keep a closed bedroom comfortable in temperatures above freezing.

Seasonal Preparation Checklist

Before each heating season, schedule a professional furnace or boiler inspection. Test your thermostat by raising the set temperature and verifying the system starts. Replace or clean your air filter. Test your carbon monoxide detectors. Clear the area around your furnace and water heater of stored items. Verify your gas fireplace starts and operates normally (if applicable). Clean your dryer vent and ensure proper exhaust airflow. Check that outdoor vent terminations are clear of debris, nests, and snow or ice.

Safety Reminder

If you smell gas, suspect carbon monoxide or believe there is an immediate danger, leave the property and contact emergency services or the appropriate gas emergency authority. Do not remain inside — exit the building immediately and call for help from outside.
