Why Your Furnace May Be Making These Noises

November 23, 2016

This is the time of year families start turning on their heaters to settle in for a frigid winter. Unfortunately, when some heaters start up, especially if it hasn’t had a yearly heating tune-up, there are some troubles that need to be inspected. A big problem you may discover is your furnace making unusual noises – check out these furnace noises you should never disregard.

Scraping Sound

If you hear a loud scraping racket that sounds like metal on metal, there is likely something wrong with the blower wheel. If you hear something like this, turn off your furnace immediately and call Falso Service Experts to inspect the equipment. There are a few things that could be faulty with the blower wheel. First, it may just be loose and if the piece is not too damaged, can be tightened. Second, it may be that the blower wheel is broken and needs to be replaced. Or third, it might be that the motor mount is what broke, causing the entire blower assembly to shake uncontrollably. One of our service experts would be happy to come over and take a look, and get you back to the quiet and cozy home you have come to adore.

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 things are a dirty furnace burner or ignitor. Stretching and contracting air ducts can also create loud bangs after the furnace blower comes on. A dirty furnace burner or ignitor could prevent the burners from igniting, resulting in gas to build up. When the gas finally does ignite, it will create the loud boom you hear. This could result in a safety issue, especially if one of those small explosions caused the heat exchanger to deteriorate. Not only could that cause a carbon monoxide leak, but you’d end up having to replace the heat exchanger, which may be very pricey.

The other trouble, stretching and contracting air ducts, is a typical noise complaint for homes with metal ducts. If your equipment is making the loud pop and it is caused by your air ducts, it could be an indication of undersized ducts, obstructed vents, or a clogged air filter. Falso Service Experts is happy to visit your home to diagnose your problem and get your home back to order. Ultimately, this will also result in improved comfort as well.

Whining Noise

If you hear a high-pitched disturbance, it could be the shaft bearings are in need of oil, there is an issue with the blower belt, or the blower motor is malfunctioning.
