Furnace Repair Tips: Sounds Your Furnace Shouldn't Make
Winter has arrived, and like most unwanted guests, it probably won't be leaving anytime soon. As a homeowner, defending your house against falling temperatures starts with proper furnace upkeep. While scheduling a yearly inspection is an extremely important maintenance step, knowing what sounds your furnace should and shouldn't make is also key to keeping your appliance healthy. To help you differentiate between normal and abnormal noises, we've created a list of sounds you don't want to hear coming from your furnace.
The sound of metal grinding against metal is a noise you never want to hear your furnace make. Unfortunately, this often indicates a part, such as the blower wheel, has come loose and is scraping against another internal mechanism. Allowing this to continue without seeking the expertise of a furnace repair technician can lead to a number of serious malfunctions. To ensure no further damage is done, turn your furnace off immediately and contact a HVAC repair company you trust.
If you hear a popping noise when your furnace initially turns on, you are most likely dealing with a dirty furnace burner. When dirt accumulates it causes a delay in the burner igniting. This leads to a build up of gas, which is why you hear a loud pop once ignition takes place. Ignoring this issue can lead to expensive repairs. Calling a HVAC company to perform a yearly inspection can prevent this problem from occurring.
A squealing or whining noise is caused by a number of issues. Fortunately, most of them are not extremely serious, but that doesn't mean you should ignore them. Your furnace may squeal when it has a slipping blower belt or the shaft bearings need oil. A HVAC technician can help you figure out why your furnace is emitting a high-pitched squeal before it turns into a more expensive repair.
If your furnace is making any of these noises or you're simply interested in scheduling a furnace inspection, please contact us today and we'll be happy to help you.
