Explaining That Weird Noise Your AC is Making

woman-reacting-to-noiseTell us if this sounds familiar: You are sitting at home enjoying some time with the family while keeping cool thanks to your air conditioning system when the calm is interrupted by an odd noise that becomes louder and more obnoxious the longer it goes on. The sound seems to be coming from your vents but you aren’t sure what is causing it. Then, you AC finishes its cooling cycle and the sound stops.

While the sound may have stopped, we urge you not to write this off as a one-time occurrence. That noise is more than likely an indicator that your unit is in need of a professional air conditioning repair in Lemoore, CA. With this in mind, let’s dive a little deeper into what the different sounds are that should alert you to a problem within your AC unit and prompt you to contact a professional.

What Is Causing That Noise?

If you are hearing odd sounds coming from your AC system, take a moment to consider if they match any of these sounds listed below.

  • Buzzing or humming: Your air conditioner might start emitting a buzzing or humming noise for a couple of reasons. One cause could be electrical parts that are starting to wear out or come loose. Another cause could be due to loosening parts creating a small humming noise as they vibrate out of their placement.
  • Clicking: It is normal to hear a small amount of clicking upon the shut down of your AC system. However, if you hear clicking throughout your unit’s cooling cycle, it means something is amiss with the thermostat or the electrical components within your AC and needs to be repaired ASAP.
  • Clanging or banging: If it sounds like there is something in your AC that is trying to play drums, you can be sure that this is an indicator that you need to schedule repairs in the near future. Often, these noises are created by loose parts or debris that are rattling around within your AC system or your ductwork. The sooner this sound is addressed the better for your unit’s long-term operation.
  • Screeching or screaming: If your cooling system seems to be screaming at you, it isn’t because it is mad. It’s because there is likely a loose fan blade that is scraping around within your AC and making this awful sound. There is also a chance that the noise is going to be caused by a refrigerant leak. In either case, you should turn your system off and call in a professional soon.
