It’s that time of year when families 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 undergone a seasonal heating tune-up, there are some problems that need to be examined. A serious problem you may discover is your furnace making weird noises – take a look at these furnace noises you should never ignore.
If you hear a loud scratching sound that sounds like metal on metal, there is possibly something faulty with the blower wheel. If you hear a sound like this, power off your furnace ASAP and call Teays Valley Service Experts Heating & Air Conditioning to inspect the system. There are a couple things that could be wrong with the blower wheel. First, it may just be loose and if the piece 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 might 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 to your home and take a look, and get you back to the silent and comfortable home you have come to love.
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 issues are a dirty furnace burner or ignitor. Extending and contracting air ducts can also cause loud sounds after the heating blower turns on. A dirty furnace burner or ignitor could delay the burners from igniting, resulting in gas to build up. When the gas does finally ignite, it will create the loud bang you hear. This could cause a safety issue, especially if one of those small explosions caused the heat exchanger to crack. Not only could that result in a carbon monoxide leak, but you would also have to replace the heat exchanger, which can be very pricey.
The other trouble, extending and contracting air ducts, is a usual noise complaint for homeowners with metal ducts. If your furnace is making the loud bang and it is a result of your air ducts, it could be a sign of undersized ducts, blocked vents, or a clogged air filter. Teays Valley Service Experts Heating & Air Conditioning is happy to set up an appointment to diagnose your issue 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 noise, 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 heating tune-up will help find these issues before they become major problems so make sure you call us at 304-760-5088 and we’ll make sure your furnace is ready to keep you safe and warm all winter long.
