Now is when families 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 examined. A big problem you may encounter is your furnace making weird noises – take a look at these furnace noises you should never neglect.
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 something like this, shut off your furnace ASAP and call Service Experts Heating & Air Conditioning to inspect the furnace. There are multiple things that could be wrong with the blower wheel. First, it might just be loose and if the component is not too impaired, can be tightened. Second, it could 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 entire blower assembly to shake uncontrollably. One of our service technicians would be happy to come out and take a look, and get you back to the silent and cozy home you have come to expect.
Loud Bang When Furnace Starts
If there is a loud bang when your furnace comes on, there are a few things that could be going on. Two common problems are a dirty furnace burner or ignitor. Extending and contracting air ducts can also produce loud bangs after the furnace blower comes on. A soiled 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 cause 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’d end up having to replace the heat exchanger, which can be very costly.
The other trouble, expanding and contracting air ducts, is a common noise complaint for people with metal ducts. If your equipment is making the loud bang and it is produced by your air ducts, it could be a sign of undersized ducts, closed vents, or a clogged air filter. Service Experts Heating & Air Conditioning is happy to visit your home to diagnose your problem and get your home back in shape for the winter. Also, this will also result in improved comfort as well.
If you hear a high-pitched disturbance, it could be the blower motor is malfunctioning, the shaft bearings are in need of oil, or an issue with the blower belt. A seasonal heating tune-up will help catch these issues before they become major problems so make sure you contact us at 330-236-4793 and we’ll make sure your heating equipment is ready to keep you safe and comfortable all winter long.
