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 problems that need to be examined. A big problem you may run into is your furnace making unusual noises – take a look at these furnace noises you should never ignore.
If you hear a loud raking racket that sounds like metal on metal, there is likely something defective with the blower wheel. If you hear a sound 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 amiss with the blower wheel. First, it could just be loose and if the part is not too harmed, can be tightened. Second, it could be that the blower wheel is broken and in need of replacement. Or third, it may be that the motor mount itself broke, causing the entire blower assembly to vibrate uncontrollably. One of our service experts would be happy to come to your home and take a look, and get you back to the silent 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 common issues are a dirty furnace burner or ignitor. Stretching and contracting air ducts can also produce loud booms after the heating blower turns on. A dirty furnace burner or ignitor could holdup the burners from igniting, resulting in gas to build up. When the gas finally does ignite, 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’d end up having to replace the heat exchanger, which can be very expensive.
The other trouble, stretching and contracting air ducts, is a common noise complaint for homes with metal ducts. If your system is making the loud bang and it is caused by 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 visit your home to diagnose your trouble and get your home back in shape for the winter. Ultimately, this will also result in improved comfort as well.
If you hear a high-pitched 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.
