This is the time of year homeowners 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 yearly heating tune-up, there are some issues that need to be inspected. A major problem you may run into is your furnace making weird noises – take a look at these furnace noises you should never neglect.
If you hear a loud scratching sound that sounds like metal on metal, there is likely something faulty with the blower wheel. If you hear a sound like this, power off your furnace ASAP and call Roy Inch & Sons Home Services by Enercare to inspect the equipment. There are a couple things that could be faulty with the blower wheel. First, it may just be loose and if the component is not too damaged, can be tightened. Second, it could be that the blower wheel is broken and needs to be replaced. Or third, it may be that the motor mount actually broke, causing the whole blower assembly to shake uncontrollably. One of our service professionals would be happy to come over and take a look, and get you back to the noiseless and warm home you have come to love.
Loud Bang When Furnace Starts
If there is a loud bang when your furnace turns on, there are a couple things that could be happening. Two general problems are a dirty furnace burner or ignitor. Extending and contracting air ducts can also produce loud noises after the heating system blower starts up. A filthy 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 pop 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 cause a carbon monoxide leak, but you’d end up having to replace the heat exchanger, which could be very expensive.
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 boom and it is produced by your air ducts, it could be a sign of undersized ducts, blocked vents, or a clogged air filter. Roy Inch & Sons Home Services by Enercare is happy to set up an appointment to diagnose your problem and get your home back in shape for the winter. Also, this will also give you improved comfort as well.
If you hear a whining noise, 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.
