Why Is My Air Conditioner Making A Cracking/Popping Sound?

Snap, crackle, and pop might be okay when it comes to your breakfast cereal, but those sounds can mean serious problems for the air conditioner in your Illinois or Northwest Indiana home. It could sound like a big piece of popping popcorn or perhaps even firecrackers. If the sound comes on suddenly and is seemingly constant, you should call Merts Heating & Air Conditioning immediately.

Nothing to mess around with

Why is your A/C unit making these noises? Among the answers are some scenarios requiring immediate attention.

  • It’s possible your system is being flooded.
      • The A/C compressor could be sucking in liquid refrigerant which can produce popping sounds. This can lead to major damage if the problem isn’t fixed quickly.
  • Various mechanical problems can also cause worrisome noises.
      • It could be caused by a bad motor bearing or a loose motor mount. It’s also possible the fan blades are hitting an obstruction in the air handler.
  • Electrical problems can also be noisy.
    • Bad or loose connections can create popping sounds. These should not be ignored. If not corrected they can start a fire or cause electrical shocks.

Not such a big deal

I want to be clear, not every sound from your A/C unit should send you into a panic. If the noise is sporadic or only happens when the system comes on, it probably doesn’t require immediate attention, but make sure to tell your Merts technician about it during air conditioning maintenance

Do not forget about the ducts

If you are hearing popping noises year-round (heating & cooling) it could be caused because your ductwork is leaking or has some design issues. While it may not require immediate attention, scheduling a repair could lower your monthly utility bills.

Be proactive

The best way to keep your A/C unit operating smoothly (and quietly) is to have regular air conditioning maintenance. In some cases, a noisy air conditioner may need expensive repairs. When that happens, its decision time. Does it make more sense to pay for the repairs or invest the money to install a new air conditioner in your Illinois or Northwest Indiana home?
