Your AC Should Never Make This Noise

It’s springtime in Florida! The only noises you should hear are the noises of birds chirping, tree branches rustling in the wind, and maybe your feet hitting the pavement headed down to the beach. Unfortunately though, all you’re hearing right now is the sound of your air conditioner clicking.

If you’re sitting at home hearing odd AC noises, you should absolutely schedule an appointment for AC repair in North Palm Beach, FL. We know that air conditioning repair can seem like a hassle, but it’s something that our team members can easily solve. We pride ourselves on service that’s both fast and effective.

You Don’t Want to Hear This

These are the noises you should never hear coming from your home’s air conditioner:

Clicking

Clicking during the start-up or shutting off of an air conditioner isn’t a problem. In fact, it’s routine. The problem arises when you hear clicking happening incessantly. Clicking is a problem that can stem from an electric issue like a failing thermostat. We’re here to figure it out and solve the problem as soon as possible for you.

Stopping and Starting

This sound is a little unlike the others because it’s not as startling. You’re sure to notice a different rhythm coming from your air conditioner though.

If you notice that your air conditioner has started to run in shorter cycles, then you’re experiencing “short cycling.” Short cycling is an efficiency issue stemming from a capacity problem. Your air conditioner could have been incorrectly sized from the start, or it could have declined in power over time due to an underlying issue. Our experts will figure out the source of the problem.

Screeching

Screeching (also described as squealing) can be the sound of a dying fan belt. Your fan belt wears down over time. A downside of this is that it can tear or become misaligned. When this happens, you’re going to notice a screeching sound due to the misplaced friction.  

Buzzing

A dull, buzzing sound coming from your air conditioner is sure to get your attention. This sound is typically the sign of fan blade trouble. It can mean that the fan blades of your motor have gotten loose. This can cause a buzzing sound because misaligned parts of your system start to touch each other when they shouldn’t.

Buzzing can also be a sign of an electrical issue. The only way to find out what’s causing your AC headache is through the consultation of a professional.

Banging

The source of banging depends on the type of banging you’re hearing. If the banging sound is loud and booming, then when you’re experiencing is more than likely a compressor problem.

If the banging is more tinny and metallic, then what you’re hearing is the sound of a loose part. Loose parts within an air conditioning system move around while the system operates and hit other parts. This problem can snowball into further damage. It’s best to address a banging sound as soon as possible no matter the source.
