Noises Your Air Conditioner Shouldn’t Be Making


Does your AC get a little noisy from time to time? It’s a machine that’s forcing air through a series of ducts and vents–it’s not exactly silent, but there are some sounds it really shouldn’t make.

In fact, if it’s making these sounds, it could signal that you need AC repair in Winter Park, FL. Let’s talk about what they are, what they mean, and how serious these sounds can really be.

Abrupt Banging Sound

Sounds like someone’s rapping on your screen door outside? Air conditioners can produce a large banging sound that normally comes from the AC cabinet outside, which is why it may sound like it’s an external noise.

When parts come loose, they vibrate and bang around. They can eventually become loose enough to damage other components in the system or stop your AC from working altogether. We put this on the top of the list for a reason.

Clicking or Light Clapping Noises

Your thermostat sends a signal to your air conditioner, and that produces a slightly audible click on some thermostats. That’s good–it means it’s trying to communicate with the AC, and if the AC comes alive and starts working after, it’s in good working order.

But when that clicking noise just doesn’t stop, it’s a problem. It usually indicates that there’s an electrical issue. If that clicking isn’t coming from its usual place at the thermostat, it could be wiring further inside of your AC. In either case, it’s electrical, and a professional should take a look at it.

Subtle Humming or Buzzing Noises

Buzzing noises are normally related to electrical problems in some fashion. Anything could be wrong since your AC uses electricity in every component, so this is hard to diagnose just from listening.

To make it clear, you should never try to repair electrical problems on your own. There’s too much that can go wrong and your safety isn’t worth the risk. Contact a professional HVAC technician to handle this for you so you don’t end up with a bigger problem than a faulty air conditioner.

Wailing Noise

When metal pieces rub against one another in normal operation, it doesn’t produce a sound. Do you know why? The pieces of metal are lubricated, so the fraction is negated and there’s no sound or damage.

But when you can hear an audible screeching or wailing sound, it sounds like a ghost is haunting your air conditioner. The lubricant has run dry, and the sound isn’t the only problem–now your AC components are under additional stress, and there’s no telling how much it can impact the rest of your machine.
