This is the time of year people start turning on their heaters to settle in for a frigid winter. Unfortunately, when some heating systems start up, especially if it hasn’t undergone a seasonal heating tune-up, there are some issues 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 ignore.
If you hear a loud raking sound that sounds like metal on metal, there is probably something wrong with the blower wheel. If you hear a sound like this, turn off your furnace immediately and call Aramendia Plumbing, Heating and Air to inspect the furnace. There are multiple things that could be amiss with the blower wheel. First, it might just be loose and if the part is not too harmed, can be tightened. Second, it could be that the blower wheel is broken and will require replacement. Or third, it could be that the motor mount actually broke, causing the entire blower assembly to vibrate uncontrollably. One of our service technicians would be happy to come out and take a look, and get you back to the noiseless and cozy home you have come to love.
Loud Bang When Furnace Starts
If there is a loud bang when your furnace comes on, there are a couple things that could be occurring. Two typical things are a dirty furnace burner or ignitor. Expanding and contracting air ducts can also cause loud booms after the heating system blower starts up. A filthy furnace burner or ignitor could delay the burners from igniting, resulting in gas to build up. When the gas finally ignites, it will create the loud boom you hear. This could result in a safety issue, especially if one of these small explosions caused the heat exchanger to deteriorate. Not only could that cause a carbon monoxide leak, but you’d end up having to replace the heat exchanger, which could be very costly.
The other trouble, stretching 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. Aramendia Plumbing, Heating and Air is happy to visit your home to diagnose your issue and get your home back in shape for the winter. Also, this will also give you improved comfort as well.
If you hear a high-pitched disturbance, it could be the blower motor is malfunctioning, the shaft bearings are in need of oil, or an issue with the blower belt. A seasonal system tune-up will help find these issues before they become big problems so make sure you contact us at 210-404-4233 and we’ll make sure your heating system is ready to keep you safe and cozy all winter long.
