This is an important warning we like to post before the start of each winter season. When the cold weather arrives, you’ll start to use your furnace on a regular basis to keep your household toasty warm. Chances are high that you have a natural gas furnace, which is the most popular type of residential heating system in North America. There are a number of good reasons for this:
- Natural gas is less expensive a fuel source than electricity.
- It’s convenient, piped right into your home.
- It burns cleanly, with few harmful emissions.
- Gas-powered furnaces can provide powerful levels of heat.
But there’s one downside to using natural gas for heat, and it’s the potential for carbon monoxide (CO) poisoning.
