Frequently Asked Questions

What should I do if my CO alarm goes off?

Evacuate immediately. Don't try to find the source - get everyone out and call 911 from outside. Don't re-enter until the fire department clears the home. Then call for HVAC inspection.

Can a furnace produce carbon monoxide?

Yes. All gas furnaces produce CO during combustion. Normally it's safely vented outside. A cracked heat exchanger or blocked flue can allow CO into your home - that's why annual inspection is critical.
