Why Your Furnace May Be Making These Noises
This is the time of year homeowners start turning on their furnaces to settle in for a long winter. Unfortunately, when some furnaces start up, especially if it hasn’t undergone a seasonal heating tune-up, there are some problems that need to be examined. A serious 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 racket that sounds like metal on metal, there is probably something defective 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 faulty with the blower wheel. First, it may just be loose and if the piece is not too impaired, can be tightened. Second, it might be that the blower wheel is broken and in need of replacement. Or third, it may be that the motor mount is what broke, causing the complete blower assembly to shake uncontrollably. One of our service technicians would be happy to come to your home and take a look, and get you back to the noiseless and comfortable home you have come to adore.
Loud Bang When Furnace Starts
If there is a loud pop when your furnace turns on, there are a couple things that could be happening. Two typical problems are a dirty furnace burner or ignitor. Expanding and contracting air ducts can also cause loud sounds after the heating system blower starts up. A filthy furnace burner or ignitor could delay the burners from igniting, causing gas to build up. When the gas finally ignites, it will create the loud boom you hear. This could cause a safety issue, especially if one of the small explosions caused the heat exchanger to break. Not only could that result in a carbon monoxide leak, but you will have to replace the heat exchanger, which may be very pricey.
The other trouble, expanding and contracting air ducts, is a common noise complaint for homeowners with metal ducts. If your equipment is making the loud boom and it is produced by your air ducts, it could be a symptom of undersized ducts, blocked vents, or a clogged air filter. Service Experts Heating, Air Conditioning & Plumbing is happy to set up an appointment to diagnose your issue and get your home back to order. Additionally, this will also result in improved comfort as well.
If you hear a whining noise, it could be the blower motor is malfunctioning, the shaft bearings are in need of oil, or an issue with the blower belt. A routine heating tune-up will help catch these issues before they become major problems so make sure you contact us at 866-397-3787 and we’ll make sure your heating equipment is ready to keep you safe and warm all winter long.
