Are These Noises from My Heating System Normal?

All heating systems will produce some level of noise, although a few operate so quietly that you will hardly ever notice them. One thing all heating systems have in common when it comes to the sounds they make: any noise that is unusual—something you don’t normally expect—is usually a warning sign that the heater requires professional repairs.

We’ll go through some of the more “common” uncommon sounds from a heater that indicate trouble. For quality repairs on your heating in Hilton Head, SC, contact AAction Air. We have 24-hour emergency service to make sure your heater keeps working for you.

Noises that May Indicate Heating Problems:

  • Booming or rumbling: This is a sound you may hear from gas furnaces, whether a standalone unit or as part of dual fuel hybrid system. It usually indicates trouble with the burner. The usual problem is the burner has too much dust or debris on it, or possibly rust flakes, and it’s preventing the gas jets from coming on. This is something that requires immediate attention; shut off the gas power to furnace and call for repairs. Another cause for a booming sound—and this applies to any HVAC system that uses ductwork—is the ducts expanding from the heat. The sound will usually only happen when you turn the heater on at the start of the season.
  • Rattling: Sometimes this issue is as simply as loose bolts on the cabinet of a furnace or heat pump. However, if the sound seems to be coming from the inside of the cabinet, it likely indicates a damaged, broken motor. The motor parts are rattling around, and the motor will soon stop working entirely. Motors need professional replacement when they burn out. The rattling sound could also be a fraying blower motor fan belt, in which case it is probably on the way to breaking away entirely, which will result in it striking against other components in the cabinet.
  • Shrieking: High-pitched noises are often warnings in furnaces and heat pumps that the motor bearings are dirty. This will eventually cause the motor to burn out.
  • Clicking: For heat pumps, this is probably a failing capacitor, which will need a replacement.

Go with the Professionals

Repairing a heating system safely and effectively is a skill that requires years of training and experience. Don’t try to open the cabinet of your heating system an attempt repairs on your own, and don’t rely on unlicensed amateurs to perform the work. Only professionals can do the work accurately and in a timely fashion, leaving you with an effective and safe heater.
