It’s that time of year when people start turning on their furnaces to settle in for a long winter. Unfortunately, when some heaters start up, especially if it hasn’t undergone a seasonal heating tune-up, there are some issues that need to be inspected. A major problem you may discover is your furnace making weird 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 possibly something defective with the blower wheel. If you hear a sound like this, power off your furnace immediately and call Broad Ripple Service Experts Heating & Air Conditioning to inspect the system. There are a few things that could be faulty with the blower wheel. First, it may just be loose and if the part 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 entire 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 noiseless 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 going on. Two typical things are a dirty furnace burner or ignitor. Stretching and contracting air ducts can also create loud booms after the furnace blower comes on. A soiled furnace burner or ignitor could holdup 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 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’d end up having to replace the heat exchanger, which may be very costly.
The other issue, extending and contracting air ducts, is a typical noise complaint for people with metal ducts. If your equipment is making the loud bang and it is a result of your air ducts, it could be a sign of undersized ducts, obstructed vents, or a clogged air filter. Broad Ripple Service Experts Heating & Air Conditioning is happy to come out to diagnose your trouble and get your home back to order. Also, this will also result in improved comfort as well.
If you hear a high-pitched sound, 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 routine system tune-up will help discover these issues before they become major problems so make sure you give us a call at 317-527-0271 and we’ll make sure your furnace is ready to keep you safe and comfortable all winter long.
