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 had a seasonal heating tune-up, there are some issues that need to be inspected. A big problem you may discover is your furnace making weird noises – take a look at these furnace noises you should never neglect.
If you hear a loud scratching noise that sounds like metal on metal, there is likely something defective with the blower wheel. If you hear a noise like this, turn off your furnace ASAP and call Service Experts Heating & Air Conditioning to inspect the furnace. There are multiple things that could be faulty with the blower wheel. First, it may just be loose and if the part is not too harmed, can be tightened. Second, it might be that the blower wheel is broken and needs to be replaced. 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 love.
Loud Bang When Furnace Starts
If there is a loud boom when your furnace turns on, there are a couple things that could be happening. Two typical issues are a dirty furnace burner or ignitor. Extending and contracting air ducts can also create loud booms after the furnace blower comes on. A dirty furnace burner or ignitor could delay the burners from igniting, forcing gas to build up. When the gas finally does ignite, it will create the loud pop you hear. This could result in a safety issue, especially if one of these small explosions caused the heat exchanger to break. 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, extending and contracting air ducts, is a usual noise complaint for homeowners with metal ducts. If your equipment is making the loud pop 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 come out to diagnose your problem and get your home back in working order. Ultimately, this will also result in 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 furnace tune-up will help catch these issues before they become big problems so make sure you contact us at 303-647-5749 and we’ll make sure your furnace is ready to keep you safe and cozy all winter long.
