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 problems that need to be assessed. A big problem you may encounter is your furnace making funny noises – read about these furnace noises you should never disregard.
If you hear a loud raking racket that sounds like metal on metal, there is likely something wrong with the blower wheel. If you hear a sound like this, turn off your furnace right away and call Bryant Heating & Cooling Service Experts to inspect the system. There are multiple things that could be faulty with the blower wheel. First, it could just be loose and if the part is not too damaged, can be tightened. Second, it might be that the blower wheel is broken and needs to be replaced. Or third, it may 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 quiet and cozy home you have come to expect.
Loud Bang When Furnace Starts
If there is a loud boom when your furnace kicks on, there are a handful of things that could be happening. Two common things are a dirty furnace burner or ignitor. Extending and contracting air ducts can also cause loud noises after the furnace blower comes on. A dirty furnace burner or ignitor could holdup the burners from igniting, forcing gas to build up. When the gas does finally ignite, it will create the loud bang you hear. This could cause a safety issue, especially if one of these small explosions caused the heat exchanger to deteriorate. Not only could that produce a carbon monoxide leak, but you’d end up having to replace the heat exchanger, which could be very pricey.
The other trouble, extending and contracting air ducts, is a usual noise complaint for homes with metal ducts. If your system is making the loud pop and it is produced by your air ducts, it could be an indication of undersized ducts, obstructed vents, or a clogged air filter. Bryant Heating & Cooling Service Experts is happy to visit your home to diagnose your issue and get your home back to order. Additionally, this will also provide 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 routine furnace tune-up will help catch these issues before they become big problems so make sure you contact us at 226-773-3357 and we’ll make sure your heating equipment is ready to keep you safe and warm all winter long.
