EPISODE 12

The HVAC Technician

David and Nicole are concerned about their gas fire place insert after it recently stopped working.


What is a red tag?

Warning tags are issued on any appliance or piping system that uses natural gas when a licensed gas technician has identified a hazardous issue. For example a cracked heat exchanger in your furnace or an improperly installed gasket on your fireplace insert. This can release carbon monoxide, an odourless and colourless gas, which can cause serious health problems if undetected. Carbon monoxide is harmful because it can rapidly accumulate in the blood, reducing the blood's ability to carry oxygen.

If carbon monoxide is leaking from a cracked heat exchanger, there is a chance of it mixing with the air that is generated by the furnace and pushed through the vents. To prevent this danger, a red tag is applied to your furnace, your local utility is notified, and your natural gas is turned off.

If you require services for your appliance you can find a list of registered heating, ventilation and air conditioning (HVAC) contractor’s on Enbridge’s Website.

If you are moving into the house in the summer months always get a licensed technician to inspect the furnace before it gets cold, this will save you the hassle and added expense of requiring electric heaters to temporarily heat your home if your furnace is red tagged.

It is also a good idea to always get a second opinion when a furnace is red tagged to avoid being taken advantage of by an unscrupulous contractor, check out this article written here
