This is the time of year families start turning on their furnaces to settle in for a long winter. Unfortunately, when some heating systems start up, especially if it hasn’t received a yearly heating tune-up, there are some issues that need to be examined. A big problem you may run into is your furnace making weird noises – check out these furnace noises you should never disregard.
If you hear a loud scratching racket that sounds like metal on metal, there is probably something faulty with the blower wheel. If you hear something like this, turn off your furnace immediately and call Service Experts Heating & Air Conditioning to inspect the furnace. There are a couple things that could be faulty with the blower wheel. First, it could 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 needs to be replaced. Or third, it could be that the motor mount is what broke, causing the whole blower assembly to vibrate 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 pop when your furnace comes on, there are a few things that could be happening. Two typical issues are a dirty furnace burner or ignitor. Stretching and contracting air ducts can also cause loud noises after the furnace blower comes on. A soiled furnace burner or ignitor could holdup the burners from igniting, causing 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 break. Not only could that produce a carbon monoxide leak, but you’d end up having to replace the heat exchanger, which can be very pricey.
The other problem, extending and contracting air ducts, is a common noise complaint for homes with metal ducts. If your equipment is making the loud pop and it is produced by your air ducts, it could be a sign of undersized ducts, blocked vents, or a clogged air filter. Service Experts Heating & Air Conditioning is happy to set up an appointment to diagnose your issue and get your home back in working order. Additionally, this will also give you improved comfort as well.
If you hear a whining disturbance, it could be the blower belt, shaft bearings in need of oil, or even a malfunctioning blower motor. A routine system tune-up will help find these issues before they become big problems so make sure you call us at 954-736-4314 and we’ll make sure your furnace is ready to keep you safe and comfortable all winter long.
