It’s that time of year when homeowners start turning on their heaters to settle in for a frigid winter. Unfortunately, when some furnaces start up, especially if it hasn’t undergone a fall heating tune-up, there are some issues that need to be assessed. A serious problem you may run into is your furnace making weird noises – read about these furnace noises you should never disregard.
If you hear a loud raking sound that sounds like metal on metal, there is likely something faulty with the blower wheel. If you hear a sound like this, turn off your furnace ASAP and call Service Experts Heating & Air Conditioning to inspect the equipment. There are a few things that could be wrong with the blower wheel. First, it may just be loose and if the component is not too harmed, can be tightened. Second, it might be that the blower wheel is broken and needs to be replaced. Or third, it could be that the motor mount is what broke, causing the whole blower assembly to rattle uncontrollably. One of our service experts would be happy to come out and take a look, and get you back to the noiseless and cozy home you have come to love.
Loud Bang When Furnace Starts
If there is a loud boom when your furnace turns on, there are a couple things that could be occurring. Two typical 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 soiled furnace burner or ignitor could prevent the burners from igniting, causing gas to build up. When the gas finally does 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 deteriorate. 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 problem, stretching and contracting air ducts, is a typical noise complaint for people with metal ducts. If your system is making the loud bang and it is a result of your air ducts, it could be an indication of undersized ducts, closed vents, or a clogged air filter. Service Experts Heating & Air Conditioning is happy to come out to diagnose your problem and get your home back to order. Also, this will also result in improved comfort as well.
If you hear a high-pitched noise, it could be the blower belt, shaft bearings in need of oil, or even a malfunctioning blower motor. A seasonal heating tune-up will help discover these issues before they become big problems so make sure you contact us at 561-629-1826 and we’ll make sure your heating equipment is ready to keep you safe and warm all winter long.
