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 cold winter. Unfortunately, when some heaters start up, especially if it hasn’t undergone a yearly heating tune-up, there are some issues that need to be inspected. A serious problem you may discover is your furnace making funny noises – read about these furnace noises you should never disregard.
If you hear a loud scraping noise that sounds like metal on metal, there is probably something faulty with the blower wheel. If you hear something like this, power off your furnace ASAP and call Becht/Givens Service Experts to inspect the equipment. There are a few things that could be amiss with the blower wheel. First, it might just be loose and if the part is not too harmed, 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 itself broke, causing the complete blower assembly to vibrate uncontrollably. One of our service technicians would be happy to come to your home and take a look, and get you back to the silent and cozy 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 happening. Two general problems are a dirty furnace burner or ignitor. Stretching and contracting air ducts can also produce loud sounds after the heating system blower starts up. A soiled furnace burner or ignitor could holdup the burners from igniting, causing gas to build up. When the gas does finally ignite, it will create the loud pop you hear. This could end up being a safety issue, especially if one of the 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 costly.
The other problem, stretching and contracting air ducts, is a usual noise complaint for people with metal ducts. If your equipment is making the loud pop and it is a result of your air ducts, it could be an indication of undersized ducts, obstructed vents, or a clogged air filter. Becht/Givens Service Experts is happy to come out to diagnose your trouble and get your home back in shape for the winter. Additionally, this will also give you improved comfort as well.
If you hear a squealing noise, 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. A seasonal furnace tune-up will help find these issues before they become big problems so make sure you contact us at 502-785-8230 and we’ll make sure your heating system is ready to keep you safe and cozy all winter long.
