This is the time of year homeowners 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 funny noises – check out these furnace noises you should never neglect.
If you hear a loud scratching sound that sounds like metal on metal, there is probably something wrong with the blower wheel. If you hear a noise like this, shut off your furnace immediately and call Service Experts Heating & Air Conditioning to inspect the system. There are multiple things that could be faulty with the blower wheel. First, it may just be loose and if the component is not too harmed, can be tightened. Second, it might be that the blower wheel is broken and in need of replacement. Or third, it could be that the motor mount is what broke, causing the entire blower assembly to rattle uncontrollably. One of our service professionals would be happy to come out and take a look, and get you back to the silent and cozy home you have come to expect.
Loud Bang When Furnace Starts
If there is a loud boom when your furnace kicks on, there are a couple things that could be happening. Two typical things are a dirty furnace burner or ignitor. Extending and contracting air ducts can also cause loud booms after the heating blower turns on. A dirty furnace burner or ignitor could delay the burners from igniting, forcing gas to build up. When the gas does finally ignite, it will create the loud pop you hear. This could result in a safety issue, especially if one of those small explosions caused the heat exchanger to crack. Not only could that produce a carbon monoxide leak, but you will have to replace the heat exchanger, which may be very costly.
The other problem, expanding and contracting air ducts, is a usual noise complaint for homeowners with metal ducts. If your system is making the loud pop and it is a result of 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 issue and get your home back to order. Additionally, this will also provide improved comfort as well.
If you hear a whining disturbance, 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. A routine heating tune-up will help find these issues before they become major problems so make sure you give us a call at 303-647-5749 and we’ll make sure your heating system is ready to keep you safe and cozy all winter long.
