Why Your Furnace May Be Making These Noises
It’s that time of year when people start turning on their heaters to settle in for a frigid winter. Unfortunately, when some heating systems start up, especially if it hasn’t received a fall heating tune-up, there are some troubles that need to be inspected. A serious problem you may run into is your furnace making weird noises – check out these furnace noises you should never disregard.
Scraping Sound
If you hear a loud raking sound that sounds like metal on metal, there is possibly something wrong with the blower wheel. If you hear something like this, turn off your furnace immediately and call Atmostemp Service Experts to inspect the furnace. There are multiple things that could be faulty with the blower wheel. First, it might just be loose and if the part is not too impaired, can be tightened. Second, it might be that the blower wheel is broken and will require replacement. Or third, it could be that the motor mount actually broke, causing the whole blower assembly to vibrate uncontrollably. One of our service technicians would be happy to come out and take a look, and get you back to the quiet and cozy home you have come to expect.
Loud Bang When Furnace Starts
If there is a loud boom when your furnace comes on, there are a few things that could be going on. Two typical issues are a dirty furnace burner or ignitor. Extending 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, resulting in gas to build up. When the gas finally ignites, it will create the loud boom you hear. This could end up being a safety issue, especially if one of these small explosions caused the heat exchanger to break. Not only could that produce a carbon monoxide leak, but you will have to replace the heat exchanger, which may be very costly.
The other problem, expanding and contracting air ducts, is a usual noise complaint for people with metal ducts. If your system is making the loud boom and it is caused by your air ducts, it could be an indication of undersized ducts, blocked vents, or a clogged air filter. Atmostemp Service Experts is happy to visit your home to diagnose your trouble and get your home back in working order. Ultimately, this will also result in improved comfort as well.
Whining Noise
If you hear a whining 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. A seasonal heating tune-up will help catch these issues before they become serious problems so make sure you call us at 856-310-4824 and we’ll make sure your furnace is ready to keep you safe and warm all winter long.
