It’s that time of year when families 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 fall heating tune-up, there are some issues that need to be examined. A serious problem you may discover is your furnace making funny noises – check out these furnace noises you should never neglect.
If you hear a loud scraping noise that sounds like metal on metal, there is probably something defective with the blower wheel. If you hear something like this, turn off your furnace ASAP and call Donelson Air Service Experts to inspect the equipment. There are a couple things that could be wrong with the blower wheel. First, it might 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 will require replacement. Or third, it may be that the motor mount is what broke, causing the whole blower assembly to rattle uncontrollably. One of our service technicians would be happy to come to your home and take a look, and get you back to the quiet and warm 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 common problems are a dirty furnace burner or ignitor. Extending and contracting air ducts can also create loud booms 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 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 break. Not only could that result in a carbon monoxide leak, but you would also have to replace the heat exchanger, which could be very costly.
The other problem, extending and contracting air ducts, is a typical noise complaint for people with metal ducts. If your equipment is making the loud pop and it is produced by your air ducts, it could be a symptom of undersized ducts, closed vents, or a clogged air filter. Donelson Air 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 result in improved comfort as well.
If you hear a squealing sound, it could be the blower belt, shaft bearings in need of oil, or even a malfunctioning blower motor. A seasonal system tune-up will help discover these issues before they become serious problems so make sure you give us a call at 615-953-9885 and we’ll make sure your heating equipment is ready to keep you safe and comfortable all winter long.
