Air Conditioning Repair: What AC Noises May Mean

Does your AC make a strange or unexpectedly loud noise during operation? Has it gotten louder over the years and is now unbearable during operation? While you can expect a certain amount of noise from your air conditioner, if it begins to make any strange sounds, you should get in touch with your HVAC technician. In some sense, you should see that sound as an advantage—many problems around the home do not let themselves be known until they are too far gone. If you view that noise as a warning signal that your AC needs the care of a professional air conditioning repair technician in Doylestown, PA.

Let’s take a look at a few sounds that you may come across during the service life of your AC:

  • Grinding: This is often a fairly grating sound, one that is immediately recognizable as an indication of damage. A grinding sound in your AC is probably related to dried-out bearings in your blower motor assembly. When dirt, dust, and grime enter into your motor, they can cause friction and overheating. If you think this is what’s going on, make sure you turn your AC off to prevent any further damage.
  • Buzzing; If you hear a buzzing sound around your AC, you might have a serious electrical problem. It might indicate an arcing issue, which can be hazardous to you and the integrity of your AC if not taken care of properly.
  • Loud banging: If it sounds like two pieces of metal are striking against one another in your AC, then that’s probably what’s going on. You may have a fan blade that has come loose or some other loose part that is being blown around your system.

It’s necessary to have a professional diagnose the sound that your AC is making so that you can be sure that the root of the problem is taken care of.
