Now is when homeowners start turning on their heating systems to settle in for a cold winter. Unfortunately, when some furnaces start up, especially if it hasn’t received a seasonal heating tune-up, there are some troubles that need to be inspected. A serious problem you may discover is your furnace making funny noises – take a look at these furnace noises you should never ignore.
If you hear a loud raking sound that sounds like metal on metal, there is probably something defective with the blower wheel. If you hear a noise like this, power off your furnace immediately and call R & M Climate Control Service Experts to inspect the equipment. There are a couple things that could be amiss with the blower wheel. First, it could just be loose and if the piece is not too harmed, can be tightened. Second, it may be that the blower wheel is broken and will require replacement. Or third, it may be that the motor mount itself broke, causing the complete blower assembly to rattle uncontrollably. One of our service experts would be happy to come over 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 turns on, there are a few things that could be going on. Two general things are a dirty furnace burner or ignitor. Extending and contracting air ducts can also create loud noises after the furnace blower comes on. A dirty furnace burner or ignitor could prevent the burners from igniting, forcing gas to build up. When the gas does finally ignite, it will create the loud boom you hear. This could result in a safety issue, especially if one of the small explosions caused the heat exchanger to deteriorate. 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 expensive.
The other trouble, expanding and contracting air ducts, is a usual noise complaint for people with metal ducts. If your furnace is making the loud bang and it is caused by your air ducts, it could be a sign of undersized ducts, blocked vents, or a clogged air filter. R & M Climate Control Service Experts is happy to set up an appointment to diagnose your issue and get your home back in working order. Additionally, this will also provide 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 discover these issues before they become major problems so make sure you call us at 865-229-6176 and we’ll make sure your heating equipment is ready to keep you safe and comfortable all winter long.
