Keep Your Intake Pipe Clear
Modern condensing furnaces operate with higher energy efficiency, generating more heat with less fuel. However, in order to do so, they require an external intake pipe for their air supply. If this pipe becomes clogged or blocked, that will not only affect your furnace’s efficiency, it can also cause a dangerous buildup of carbon monoxide.
If you have a high-efficiency furnace, look for the intake and exhaust pipes on the exterior of your home. Make sure they’re free of ice, snow, and other obstructions like bird nests or insects. If you cannot easily check the status of your pipe, contact a qualified heating and cooling professional to do it for you!
