Your furnace plays an essential role in your Bluffton, GA household. When it makes weird noises, your concern is understandable. Here is what the different sounds mean.
Banging and Popping Noises
You’ll hear these noises when your heater’s metal ducts expand and contract because of temperature changes when the furnace cycles on and off. These noises are no reason for concern when they occur occasionally.
However, if they happen all the time, there’s a delay with the ignition of the burners. If this is the case, you’ll need to clean or replace the burners.
Screeching or Squealing Noises
When you hear your heater making these noises, it indicates a problem with the blower motor belt or worn-out bearings. Taking care of this issue right away can prevent much larger problems in the future.
Booming or Rumbling Noises
If your furnace makes a loud rumble when it completes a cycle, it means the fuel is still burning even when the burners shut down. This noise can have several sources, including the burners, flame sensors and pilot lights. Testing the pilot light and cleaning the unit can resolve the issue.
Whistling or Hissing Noises
Whistling or hissing indicates a leak in the system or a problem with the ductwork. This causes the furnace to work hard and leads to inefficiency. Sealing all your ducts and clearing any obstructions will help solve this problem.
Tapping or Clicking Noises
You can expect to hear tapping or clicking noises when the furnace starts a cycle. But if they occur all the time, there’s a problem with the ignition. Cleaning the burners and checking the ignition control board can help with this issue.
