Why Your Furnace May Be Making These Noises

November 23, 2016

It’s that time of year when families 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 yearly heating tune-up, there are some problems that need to be examined. A big problem you may encounter is your furnace making unusual noises – take a look at these furnace noises you should never neglect.

Scraping Sound

If you hear a loud scratching noise that sounds like metal on metal, there is probably something defective with the blower wheel. If you hear a sound like this, shut off your furnace immediately and call Sunbeam Service Experts to inspect the system. There are a couple things that could be faulty with the blower wheel. First, it could just be loose and if the part is not too impaired, can be tightened. Second, it may be that the blower wheel is broken and will require replacement. Or third, it could be that the motor mount is what broke, causing the complete blower assembly to rattle uncontrollably. One of our service professionals would be happy to come to your home and take a look, and get you back to the noiseless and cozy home you have come to love.

Loud Bang When Furnace Starts

If there is a loud pop when your furnace turns on, there are a few things that could be occurring. Two general things are a dirty furnace burner or ignitor. Expanding and contracting air ducts can also create loud bangs after the heating system blower starts up. 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 result in a safety issue, especially if one of these small explosions caused the heat exchanger to deteriorate. Not only could that cause a carbon monoxide leak, but you would also have to replace the heat exchanger, which can be very pricey.

The other trouble, extending and contracting air ducts, is a common noise complaint for homes 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, obstructed vents, or a clogged air filter. Sunbeam Service Experts is happy to set up an appointment to diagnose your trouble and get your home back to order. Also, this will also result in improved comfort as well.

Whining Noise

If you hear a whining 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 routine system tune-up will help find these issues before they become major problems so make sure you give us a call at 716-427-6807 and we’ll make sure your heating equipment is ready to keep you safe and comfortable all winter long.
