This is the time of year families start turning on their furnaces 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 troubles that need to be examined. A major problem you may run into is your furnace making weird noises – take a look at these furnace noises you should never neglect.
If you hear a loud scraping racket that sounds like metal on metal, there is likely something faulty with the blower wheel. If you hear a sound like this, turn off your furnace right away and call Service Experts Heating, Air Conditioning & Plumbing to inspect the system. There are a couple things that could be wrong with the blower wheel. First, it might just be loose and if the component is not too harmed, 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 shake uncontrollably. One of our service professionals would be happy to come to your home and take a look, and get you back to the quiet and comfortable home you have come to expect.
Loud Bang When Furnace Starts
If there is a loud pop when your furnace comes on, there are a few things that could be occurring. Two typical issues are a dirty furnace burner or ignitor. Extending and contracting air ducts can also create loud booms after the heating system blower turns on. A soiled furnace burner or ignitor could holdup the burners from igniting, causing gas to build up. When the gas finally ignites, it will create the loud pop you hear. This could cause 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 could be very expensive.
The other trouble, 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 a result of your air ducts, it could be a sign of undersized ducts, blocked vents, or a clogged air filter. Service Experts Heating, Air Conditioning & Plumbing is happy to visit your home to diagnose your trouble and get your home back in working order. Ultimately, this will also give you improved comfort as well.
If you hear a high-pitched disturbance, it could be the blower belt, shaft bearings in need of oil, or even a malfunctioning blower motor. A routine heating tune-up will help find these issues before they become big problems so make sure you contact us at 866-397-3787 and we’ll make sure your heating system is ready to keep you safe and cozy all winter long.
