HVAC combustion appliance safety checklist in Greater Vancouver

Most Greater Vancouver homes rely on at least one gas appliance for heat or hot water, and a yearly safety check keeps those appliances running cleanly. Here is what a combustion appliance safety check involves and why it matters in our climate, with the homeowner steps you can handle in between.

What a professional safety check covers

A combustion appliance safety check is performed by a licensed gas technician and looks at how each gas appliance burns fuel and vents the resulting gases. The technician inspects the appliance, tests the draft and venting, measures combustion, and confirms there is adequate air for the appliance to operate safely. The goal is to make sure exhaust is leaving the home completely and nothing is spilling back indoors.

For Lower Mainland homes, this matters most as the heating season begins. After a long, damp summer, venting can collect moisture, debris, or corrosion, and tightly sealed homes can struggle to supply enough combustion air, especially when range hoods and dryers are running.

• Inspection of each gas appliance and its venting
• Draft and combustion testing
• Verification of adequate combustion air supply
• Check for exhaust spillage or backdrafting

What homeowners can safely do

Between professional checks, there are a few safe things you can do. Keep the area around each appliance clear and free of stored items, so the appliance gets the air it needs and the venting stays accessible. Make sure outdoor vent terminals are not blocked by debris, snow, or vegetation. And keep your carbon monoxide detectors in place, tested, and within their expiry date.

What you should not do is open up an appliance, adjust burners, or work on venting connections. Those are licensed-technician tasks. Your role is to keep things clear, watch for warning signs, and book the inspection.

• Keep stored items clear of appliances and vents
• Check that outdoor vent terminals are unobstructed
• Test CO detectors monthly and replace expired ones
• Watch for soot, persistent pilot-out, or unusual smells

Why an annual check is worth it

A yearly safety check catches venting and combustion problems before they become hazards, helps appliances run more efficiently, and gives you peace of mind heading into winter. HeatLand can perform a combustion appliance safety check on your home's gas equipment and confirm everything is operating and venting as it should.

Frequently Asked Questions

How often should I have a combustion safety check?

Once a year is a sensible schedule, ideally before heating season begins in the fall. It catches venting, draft, and combustion issues early and keeps your appliances running efficiently.

Can I do a combustion safety check myself?

No. Combustion and draft testing require a licensed technician with the right instruments. Homeowners can keep areas clear, check outdoor vents, and maintain CO detectors, but the inspection itself is a pro job.

What warning signs mean I should book sooner?

Soot or staining around an appliance, a pilot or burner that keeps going out, unusual smells, heavy condensation on windows, or a CO detector alarm all warrant prompt professional attention.

Does sealing up my home affect appliance safety?

It can. Tighter homes have less natural air infiltration, so a gas appliance may not get enough combustion air, especially when exhaust fans run. A safety check verifies there is adequate air supply for your appliances.
