It’s that time of year when homeowners start turning on their heating systems to settle in for a cold winter. Unfortunately, when some heating systems start up, especially if it hasn’t received a yearly heating tune-up, there are some troubles that need to be inspected. A serious problem you may discover is your furnace making funny noises – take a look at these furnace noises you should never ignore.
If you hear a loud scraping noise that sounds like metal on metal, there is probably something wrong with the blower wheel. If you hear something like this, power off your furnace right away and call Service Experts Heating & Air Conditioning to inspect the system. There are a couple things that could be faulty with the blower wheel. First, it might just be loose and if the piece is not too harmed, can be tightened. Second, it could be that the blower wheel is broken and will require replacement. Or third, it might be that the motor mount itself broke, causing the entire blower assembly to vibrate uncontrollably. One of our service technicians would be happy to come to your home and take a look, and get you back to the quiet and cozy home you have come to adore.
Loud Bang When Furnace Starts
If there is a loud pop when your furnace kicks on, there are a few things that could be occurring. Two general things are a dirty furnace burner or ignitor. Expanding and contracting air ducts can also cause loud bangs after the heating system blower starts up. A dirty furnace burner or ignitor could holdup the burners from igniting, causing gas to build up. When the gas finally ignites, it will create the loud pop you hear. This could end up being a safety issue, especially if one of the small explosions caused the heat exchanger to deteriorate. Not only could that cause a carbon monoxide leak, but you would also have to replace the heat exchanger, which can be very costly.
The other problem, expanding and contracting air ducts, is a usual noise complaint for homeowners with metal ducts. If your system is making the loud boom and it is a result of your air ducts, it could be a symptom of undersized ducts, closed vents, or a clogged air filter. Service Experts Heating & Air Conditioning is happy to set up an appointment to diagnose your issue and get your home back to order. Also, this will also provide improved comfort as well.
If you hear a high-pitched disturbance, it could be the blower motor is malfunctioning, the shaft bearings are in need of oil, or an issue with the blower belt. A seasonal system tune-up will help catch these issues before they become major problems so make sure you call us at 801-871-8425 and we’ll make sure your heating equipment is ready to keep you safe and comfortable all winter long.
