Why Your Furnace May Be Making These Noises
This is the time of year homeowners start turning on their heating systems 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 issues that need to be inspected. A serious problem you may encounter is your furnace making funny noises – check out these furnace noises you should never neglect.
If you hear a loud raking noise that sounds like metal on metal, there is likely something faulty with the blower wheel. If you hear something like this, turn off your furnace right away and call Stallion Heating and Air Conditioning to inspect the equipment. There are multiple things that could be amiss with the blower wheel. First, it may just be loose and if the component is not too impaired, can be tightened. Second, it may be that the blower wheel is broken and in need of replacement. Or third, it could be that the motor mount itself broke, causing the complete blower assembly to rattle uncontrollably. One of our service experts would be happy to come over and take a look, and get you back to the quiet and comfortable home you have come to adore.
Loud Bang When Furnace Starts
If there is a loud boom when your furnace kicks on, there are a couple things that could be occurring. Two typical problems are a dirty furnace burner or ignitor. Stretching and contracting air ducts can also produce loud noises after the furnace blower starts up. A soiled furnace burner or ignitor could holdup the burners from igniting, forcing gas to build up. When the gas does finally ignite, it will create the loud boom you hear. This could end up being a safety issue, especially if one of those small explosions caused the heat exchanger to deteriorate. Not only could that produce a carbon monoxide leak, but you will have to replace the heat exchanger, which may be very pricey.
The other issue, extending and contracting air ducts, is a usual noise complaint for homes with metal ducts. If your system is making the loud boom and it is caused by your air ducts, it could be a sign of undersized ducts, obstructed vents, or a clogged air filter. Stallion Heating and Air Conditioning is happy to visit your home to diagnose your trouble and get your home back to order. Also, this will also result in improved comfort as well.
If you hear a whining 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 system tune-up will help catch these issues before they become serious problems so make sure you contact us at 215-259-5850 and we’ll make sure your furnace is ready to keep you safe and cozy all winter long.
