Why Your Furnace May Be Making These Noises
Now is when people start turning on their heaters to settle in for a frigid winter. Unfortunately, when some heaters start up, especially if it hasn’t received a fall heating tune-up, there are some issues that need to be assessed. A big problem you may discover is your furnace making weird noises – read about these furnace noises you should never neglect.
Scraping Sound
If you hear a loud raking noise that sounds like metal on metal, there is probably something faulty with the blower wheel. If you hear something like this, shut off your furnace ASAP and call Service Experts Heating & Air Conditioning to inspect the equipment. There are a couple things that could be wrong with the blower wheel. First, it may just be loose and if the part is not too damaged, can be tightened. Second, it could be that the blower wheel is broken and will require replacement. Or third, it might 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 silent 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 couple things that could be happening. Two common issues are a dirty furnace burner or ignitor. Extending and contracting air ducts can also cause loud bangs after the heating system blower turns on. A dirty furnace burner or ignitor could delay the burners from igniting, forcing gas to build up. When the gas finally ignites, it will create the loud bang you hear. This could cause a safety issue, especially if one of those small explosions caused the heat exchanger to crack. Not only could that result in a carbon monoxide leak, but you will have to replace the heat exchanger, which can be very pricey.
The other problem, stretching and contracting air ducts, is a typical noise complaint for people 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, obstructed 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. Additionally, this will also result in improved comfort as well.
