Is Your Heating System Really Safe?
The good news is that heating systems in modern homes are safer than they’ve ever been before. But while many people never experience any major risk to their safety due to a furnace or boiler, it’s still a possibility. Any heating system that uses combustion to work, like a natural gas furnace, could potentially leak a dangerous gas called carbon monoxide (CO, for short) into the home.
The heat exchanger is where combustion produces a flame as natural gas ignites. This heat is contained within a heat exchanger made of aluminum or steel. It is essentially a curved tube, and the smoke and carbon monoxide byproducts vent through the other end and out of the house. Air blows over the heat exchanger to heat up and is sent to the ducts running throughout the home.
Unfortunately, over time, the heat exchanger can become damaged. This is especially true if you have anyone but a professional technician work on your furnace, but it can also happen with time. You should have HVAC technicians inspect your heating system each and every year to check for leaks and cracks.
Carbon monoxide is an odorless, colorless gas. That means you wouldn’t have many ways to notice if it were in your home. It is poisonous, and sometimes people don’t know about it until people in the house start to get sick.
Carbon monoxide detectors save lives. A CO detector near each room where people sleep (and throughout your living spaces) should be tested each month and replaced every 5-10 years. You should also replace the batteries for your CO and smoke alarms every 6 months (even if the test works).
