VIDEO: Is your furnace a silent killer?

How are you doing Tom?

What causes carbon monoxide to leak from a furnace?

Cracks in the heat exchanger. Age. Various different things. Just rust building up in the heat exchangers. Poor ventilation. There’s a lot of factors that go into it.

How do you check for carbon monoxide in your inspection?

First off, we do a visual inspection of the actual heat exchangers themselves. Specifically, we do a visual carbon monoxide reading inside the home. The most common place for gas leaks, natural gas leaks, and adducts come from these mechanical flare fittings that attach the household gas to the furnace. When there is a leak, the entire flexible gas connector from this fitting here, on to the attaching fitting there has to be replaced. Depending on the age of the furnace, we can either replace the heat exchanger itself, if it’s available. Otherwise the system would have to be replaced.

When the inspection’s done, how do we know if there’s carbon monoxide still in the house?

After installing any furnace or servicing any furnace, we either recommend the installation of carbon monoxide detectors in every bedroom house. Or after any installation by us, we will include at least two carbon monoxide for the home to ensure that there’s no carbon monoxide inside the house.

Protecting yourself from the silent killer is easy with the right tools and a proper inspection. This wintry season, stay warm and stay safe. For HomeShowRadio.com, I’m Tom Tyman.

Carbon monoxide is responsible for as many as 170 deaths in US homes each year according to the US Consumer Product Safety Commission. It's colorless and odorless, so you can't even tell if you're breathing it until it's too late. Your faulty furnace could be the culprit. How do you know if its leaking this deadly fume? Absolute Comfort technician Hector Contreras shows you how a simple inspection can protect you and your family this wintery season.
