Now is when families start turning on their heaters to settle in for a frigid winter. Unfortunately, when some heating systems start up, especially if it hasn’t undergone a fall heating tune-up, there are some issues that need to be examined. A serious problem you may discover is your furnace making unusual noises – read about these furnace noises you should never neglect.
If you hear a loud raking sound that sounds like metal on metal, there is likely something wrong with the blower wheel. If you hear something like this, shut off your furnace ASAP and call Stallion Heating Plumbing Air Conditioning to inspect the furnace. There are multiple things that could be faulty with the blower wheel. First, it may just be loose and if the component is not too damaged, can be tightened. Second, it might be that the blower wheel is broken and will require replacement. Or third, it might be that the motor mount is what broke, causing the whole blower assembly to rattle 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 bang when your furnace comes on, there are a few things that could be occurring. Two general problems are a dirty furnace burner or ignitor. Expanding and contracting air ducts can also produce loud bangs after the heating system blower starts up. A soiled furnace burner or ignitor could prevent the burners from igniting, forcing 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 these small explosions caused the heat exchanger to crack. Not only could that cause a carbon monoxide leak, but you will have to replace the heat exchanger, which may be very expensive.
The other trouble, stretching and contracting air ducts, is a usual noise complaint for homeowners with metal ducts. If your furnace is making the loud pop and it is produced by your air ducts, it could be a sign of undersized ducts, obstructed vents, or a clogged air filter. Stallion Heating Plumbing Air Conditioning is happy to come out to diagnose your trouble and get your home back in shape for the winter. 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. An annual heating tune-up will help discover these issues before they become major problems so make sure you contact us at 215-278-9690 and we’ll make sure your heating system is ready to keep you safe and cozy all winter long.
