We Speak AC: What That Weird Sound Means

If you read through our blog, then you know that we tend to speak highly of our technicians. This is because our team is a family, and we take the time to make sure our professionals are up to our high standards. One of the many things that our professionals can do is “speak” AC.

What do we mean by this? Well, have you ever had one of those days where your air conditioner is just making some weird noise and you have no idea what it means? Your air conditioner is trying to tell you something, but you can’t speak the language. We’re here to act as your translator. We speak AC and we want to help usher you into a cool, stress-free summer.

Sounds and Their Meanings

We’re here for your air conditioning repair in Sandy, UT. Here’s what sound you might hear coming from your air conditioner and what it means:

Running Water

You know this is odd. There’s no good reason that your air conditioner should sound like it’s a running stream.

If you hear this sound, then you’re literally hearing the sound of your air conditioner struggling to handle excess condensation. Your air conditioning system can handle a bit of humidity. If there’s an excess amount of condensation that isn’t draining properly though, you’ll start to hear the sound of water running. Don’t panic—just contact our professionals.


Another odd “nature sound” is coming from your air conditioner. This time it’s the sound of wind rushing. If you hear this, then what you’re hearing is the sound of your vents failing you somewhere.

This is more of a ductwork issue, but it’s going to have a direct impact on your air conditioning this spring and summer. This is a sound that you might hear even if your air conditioner is working. We want you to know that it isn’t working well though and it will decrease in power over time.


Rattling or any type of tinny racket you hear is typically due to a loose part. Although something is misaligned, your air conditioner is still going to attempt to run like normal. When this happens, you should contact a professional as soon as possible. A loose part has the potential to damage other areas of your AC system.


Clicking sounds can be one of two things: an electrical issue or a fan blade issue. If you can trace back the clicking sound to your thermostat, then it’s likely electrical. If the clicking sound is more rhythmic, then you might have an obstructed fan blade. A professional is the only one qualified to get to the bottom of this.

Booming / Loud Noises

Booming or loud noises typically indicate a big problem with your air conditioning system. A banging noise might indicate a problem with your compressor or even your home’s indoor blower system. This is a fast-paced trail to damage and major AC issues. Make sure you contact a professional ASAP if you notice this.
