Restricted airflow can cause your heat exchanger to crack and leak a very dangerous gas into your home. The potentially fatal and odorless gas is carbon monoxide (CO).
Let me explain…
A clogged filter restricts airflow which causes your furnace heat exchanger to overheat. When they overheat, they crack. Once a heat exchanger cracks, the CO leaks into your home. The purpose of the air filter is to catch dust and debris from entering your HVAC system. Over time, they get full of dust and debris and air cannot properly flow through which causes something you do NOT want: Restricted Airflow.
Your heat exchangers job is to heat up and transfer the heat to the air that passes through the furnace. When they heat up the metal expands which makes the cracks much bigger. This will allow more carbon monoxide fumes to enter your home.
Carbon monoxide (CO) is called the “silent killer” because it is odorless, colorless, deadly, poisonous gas. People might not even know that they are being exposed. Initial symptoms of CO poisoning are similar to the flu
- Shortness of breath
High levels of CO poisoning results in more symptoms:
- Mental Confusion
- Loss of Muscular coordination
- Loss of consciousness
- Ultimately death
I think it goes without saying that carbon monoxide isn’t something that you want in your home.
