Now is 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 yearly heating tune-up, there are some issues that need to be examined. A big problem you may run into is your furnace making unusual noises – check out these furnace noises you should never ignore.
Scraping Sound
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 noise like this, turn off your furnace right away and call Service Experts Heating & Air Conditioning to inspect the system. There are multiple things that could be wrong with the blower wheel. First, it may just be loose and if the part is not too harmed, can be tightened. Second, it may be that the blower wheel is broken and in need of replacement. Or third, it could 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 out and take a look, and get you back to the quiet and warm 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 typical things are a dirty furnace burner or ignitor. Stretching and contracting air ducts can also produce loud booms after the heating blower turns on. A filthy furnace burner or ignitor could holdup the burners from igniting, resulting in gas to build up. When the gas does finally ignite, it will create the loud bang you hear. This could result in a safety issue, especially if one of those small explosions caused the heat exchanger to deteriorate. Not only could that result in a carbon monoxide leak, but you would also have to replace the heat exchanger, which could be very expensive.
The other trouble, stretching and contracting air ducts, is a typical noise complaint for homes with metal ducts. If your equipment is making the loud pop and it is a result of your air ducts, it could be a symptom of undersized ducts, closed vents, or a clogged air filter. Service Experts Heating & Air Conditioning is happy to come out to diagnose your trouble and get your home back in shape for the winter. Additionally, this will also provide improved comfort as well.

If you hear a high-pitched sound, it could be the blower belt, shaft bearings in need of oil, or even a malfunctioning blower motor.
