This is the time of year people start turning on their furnaces to settle in for a long winter. Unfortunately, when some furnaces start up, especially if it hasn’t had a yearly heating tune-up, there are some issues that need to be examined. A major problem you may run into is your furnace making unusual 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 likely something faulty with the blower wheel. If you hear something like this, power off your furnace immediately and call Peachtree Service Experts to inspect the equipment. There are multiple things that could be amiss with the blower wheel. First, it may just be loose and if the piece is not too damaged, can be tightened. Second, it may be that the blower wheel is broken and needs to be replaced. Or third, it might be that the motor mount actually broke, causing the entire blower assembly to vibrate uncontrollably. One of our service professionals would be happy to come over and take a look, and get you back to the silent and warm 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 occurring. Two common things are a dirty furnace burner or ignitor. Stretching and contracting air ducts can also create loud booms after the heating system blower starts up. A soiled furnace burner or ignitor could prevent the burners from igniting, forcing gas to build up. When the gas finally does ignite, it will create the loud boom you hear. This could end up being a safety issue, especially if one of the small explosions caused the heat exchanger to deteriorate. Not only could that result in a carbon monoxide leak, but you will have to replace the heat exchanger, which can be very costly.
The other problem, extending and contracting air ducts, is a typical noise complaint for homes with metal ducts. If your system is making the loud pop and it is produced by your air ducts, it could be a symptom of undersized ducts, closed vents, or a clogged air filter. Peachtree Service Experts is happy to come out to diagnose your problem and get your home back in working order. Additionally, this will also give you improved comfort as well.
Whining Noise
If you hear a high-pitched noise, it could be the blower motor is malfunctioning, the shaft bearings are in need of oil, or an issue with the blower belt. An annual system tune-up will help find these issues before they become major problems so make sure you call us at 678-235-9699 and we’ll make sure your furnace is ready to keep you safe and comfortable all winter long.
