Why Is My Air Conditioning System So Loud?

Few things are as irritating as a loud noise emitting from one of your home appliances. You should expect a reasonable amount of noise during your air conditioner’s operation, but a particularly loud or unusual sound is often an indication that something has gone wrong with your system itself. We have seen a wide variety of issues in our time, but a loud noise is one of the most frequent signs that a problem with your AC should be fixed. If you find that your air conditioning system has become noisy, then you should call for professional air conditioning services in Naperville, IL from DuAll Heating & Cooling.

Let’s take a look at  few different loud noises that may frustrate your cooling experience as well as their possible causes:

  • Banging. If you find that your AC emits a banging noise, it could be a strong indication that there is some kind of loose part within your system. This is probably responsible for the metal-on-metal sound. But another possible cause is a bent or damage part whose deformed shape is now hitting an adjacent component. For example, your AC may have a bent fan blade that now hits the interior surface of the unit as it spins.
  • Buzzing. If you hear a loud buzzing noise emitting from your AC, then it could be an indication that your system has an electrical problem. This is potentially hazardous so it’s best not to tamper with any parts on your own. It’s far better to ensure that your AC is serviced by a professional. Electrical “arcing” can be hazardous to your home and your health.
  • Grinding. If you hear a grinding noise, you should shut off your AC and call for professional assistance. This is likely an indication of dried-out bearings, whether at the blower motor or somewhere else. It’s an indication that there is something seriously wrong with system, and continuing to operate it could potentially lead to serious damage and major component replacement.
