This is the time of year families start turning on their furnaces to settle in for a long winter. Unfortunately, when some heating systems start up, especially if it hasn’t received a fall heating tune-up, there are some troubles that need to be examined. A serious problem you may discover is your furnace making weird noises – check out these furnace noises you should never disregard.
If you hear a loud scraping sound that sounds like metal on metal, there is probably something faulty with the blower wheel. If you hear a sound like this, shut off your furnace right away and call Comfort Masters Service Experts Heating & Air Conditioning to inspect the equipment. There are a few things that could be wrong with the blower wheel. First, it might just be loose and if the part is not too impaired, can be tightened. Second, it may be that the blower wheel is broken and will require replacement. Or third, it might be that the motor mount actually broke, causing the entire blower assembly to vibrate uncontrollably. One of our service experts would be happy to come to your home and take a look, and get you back to the quiet and comfortable home you have come to expect.
Loud Bang When Furnace Starts
If there is a loud pop when your furnace turns on, there are a few things that could be occurring. Two typical issues are a dirty furnace burner or ignitor. Stretching and contracting air ducts can also create loud bangs after the heating blower turns on. A soiled furnace burner or ignitor could delay the burners from igniting, forcing gas to build up. When the gas does finally ignite, it will create the loud pop you hear. This could cause a safety issue, especially if one of these small explosions caused the heat exchanger to deteriorate. Not only could that result in a carbon monoxide leak, but you will have to replace the heat exchanger, which may be very pricey.
The other trouble, stretching and contracting air ducts, is a usual noise complaint for homeowners with metal ducts. If your equipment is making the loud boom and it is produced by your air ducts, it could be a symptom of undersized ducts, blocked vents, or a clogged air filter. Comfort Masters Service Experts Heating & Air Conditioning is happy to come out to diagnose your issue and get your home back to order. Also, this will also provide improved comfort as well.
If you hear a squealing sound, it could be the blower motor is malfunctioning, the shaft bearings are in need of oil, or an issue with the blower belt. An annual furnace tune-up will help find these issues before they become big problems so make sure you give us a call at 847-250-6729 and we’ll make sure your heating system is ready to keep you safe and comfortable all winter long.
