Carbon Monoxide and your HVAC

Carbon monoxide leaks in your system can kill you. We all know the danger and have heard the horror stories of people unknowingly breathing in the colorless, odorless gas. In fact, it can poison you without warning. That is why carbon monoxide detectors are installed throughout your business and home.

What Is Carbon Monoxide?

Carbon Monoxide is a poisonous gas that can kill you. It is often called a “silent killer” because it is odorless and tasteless. People cannot tell when this gas is being released inside their home or business.

A malfunctioning furnace or boiler can cause serious problems. Gases that do not properly vent can cause high levels of carbon monoxide to release into the air. A cracked heat exchanger can also cause these gases to be released into your home or business, where it can kill. A carbon monoxide leak within your system can kill.
