It’s that time of year when homeowners start turning on their heating systems to settle in for a cold winter. Unfortunately, when some furnaces start up, especially if it hasn’t undergone a yearly heating tune-up, there are some problems that need to be examined. A serious problem you may run into is your furnace making unusual noises – take a look at these furnace noises you should never ignore.
If you hear a loud scratching noise that sounds like metal on metal, there is probably something defective with the blower wheel. If you hear a sound like this, power off your furnace ASAP and call Stevenson Service Experts to inspect the equipment. There are multiple things that could be faulty with the blower wheel. First, it might just be loose and if the part is not too impaired, can be tightened. Second, it may be that the blower wheel is broken and in need of replacement. Or third, it could be that the motor mount actually broke, causing the complete blower assembly to rattle 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 kicks on, there are a couple things that could be going on. Two general problems are a dirty furnace burner or ignitor. Stretching and contracting air ducts can also create loud sounds after the furnace blower comes on. A dirty 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 bang you hear. This could cause a safety issue, especially if one of those small explosions caused the heat exchanger to deteriorate. Not only could that produce a carbon monoxide leak, but you will have to replace the heat exchanger, which may be very pricey.
The other issue, stretching 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 caused by your air ducts, it could be an indication of undersized ducts, blocked vents, or a clogged air filter. Stevenson Service Experts is happy to visit your home to diagnose your trouble and get your home back to order. Also, this will also provide improved comfort as well.
If you hear a whining noise, it could be the blower belt, shaft bearings in need of oil, or even a malfunctioning blower motor. A routine furnace tune-up will help find these issues before they become major problems so make sure you give us a call at 614-334-3192 and we’ll make sure your heating equipment is ready to keep you safe and warm all winter long.
