This is the time of year families start turning on their heating systems to settle in for a cold winter. Unfortunately, when some heaters start up, especially if it hasn’t received a fall heating tune-up, there are some problems that need to be examined. A major problem you may encounter is your furnace making funny noises – check out these furnace noises you should never disregard.
If you hear a loud scraping racket that sounds like metal on metal, there is possibly something wrong with the blower wheel. If you hear a sound like this, shut off your furnace ASAP and call A-PLUS Service Experts Heating & Air Conditioning to inspect the furnace. There are a couple things that could be faulty with the blower wheel. First, it might just be loose and if the part is not too damaged, can be tightened. Second, it could be that the blower wheel is broken and will require replacement. Or third, it could be that the motor mount actually broke, causing the entire blower assembly to shake 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 warm home you have come to expect.
Loud Bang When Furnace Starts
If there is a loud boom when your furnace kicks on, there are a few things that could be going on. Two typical things are a dirty furnace burner or ignitor. Extending and contracting air ducts can also produce loud bangs after the heating system blower starts up. A dirty furnace burner or ignitor could prevent the burners from igniting, causing gas to build up. When the gas finally does ignite, it will create the loud bang you hear. This could result in a safety issue, especially if one of those small explosions caused the heat exchanger to break. Not only could that result in a carbon monoxide leak, but you’d end up having to replace the heat exchanger, which can be very expensive.
The other trouble, extending and contracting air ducts, is a usual noise complaint for homes with metal ducts. If your equipment is making the loud boom and it is a result of your air ducts, it could be a sign of undersized ducts, blocked vents, or a clogged air filter. A-PLUS Service Experts Heating & Air Conditioning is happy to visit your home to diagnose your problem and get your home back to order. Additionally, this will also result in 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 furnace tune-up will help find these issues before they become serious problems so make sure you give us a call at 301-747-3140 and we’ll make sure your heating equipment is ready to keep you safe and warm all winter long.
