AC Making These Sounds? It Might be a Problem

Your AC makes its usual noises, like the sound of air flowing through vents, and maybe a bit of a hum as it kicks on in the middle of the night when there’s no competing sounds. That’s okay, but there are sounds it’s not supposed to make that you really need to know about.

During AC repair in Sarasota, FL , we’ve seen quite a few problems. We’ve been called for noises like you wouldn’t believe, and chief among them are these sounds. If you hear these, it’s time to call for repairs.

Heavy Banging Noises

It sounds like someone is inside your ductwork just banging their fists on it. That’s not a pleasant noise, and what it means for your AC is even worse. This is a sound coming from your compressor, which can happen when something comes loose. It this sound is left alone for too long, it can result in more components knocking around, since your compressor might be vibrating and causing other pieces to loosen nearby. This is a reason to shut down your AC and call for repairs.

Loud Clunky Sounds

Think of metal clunking against metal. That’s what we’re talking about. This is most likely your fan blades causing vibration, and those slowly loosen screws and bolts over time. When the fan blades lose alignment, the edges of them can clang against other nearby components and cause this sound. While it doesn’t sound like the biggest problem, it can lead your fan blades to come off entirely, and that only leads to more damage.

Electrical Buzzing Sounds

Your electrical system shouldn’t be audibly buzzing, especially not the one in your air conditioner. This could be the blower motor beginning to give out on you. The noise doesn’t always come from your vents, but sometimes it can, and the blower motor is one of the last components leading up to your conditioned air coming through the vents.

Loud Metal Screeching Noise

Your air conditioner shouldn’t sound like two pieces of metal rubbing against each other. This happens when two metal components, which are supposed to come into contact with one another, lose lubrication and create friction instead. Your metal parts are lubricated every year during your annual tune-up, but it doesn’t last forever.

This one is a big problem, because you’re hearing tension and pressure when those noises come out. This means your AC is under a lot more mechanical strain than it’s used to, and it’s a pretty big problem. This one requires you to turn off your AC and give us a call.
