How AC Maintenance Can Prevent These Awful AC Sounds


Your air conditioner is fairly quiet. It’s just doing its thing, making the house cool, and not bothering anyone in the process. But all it takes is a lack of maintenance schedule and proper planning to throw it into disrepair.

Without air conditioning maintenance in Winter Park, FL, your AC will show signs of trouble, and most often it’ll be done through sound. 

Buzzing or Humming Noises

Buzzing is nearly almost a sign of an electrical issue. When you hear a light hum or buzz, whether your AC is on or not, it could spell trouble. So how does maintenance prevent this from happening in the first place?

During maintenance, we inspect your HVAC system’s electrical components. If one of them is about to fail, such as a compressor, we can usually tell before it becomes a problem that could lead to a full-scale breakdown. We can just replace it then and there.

Banging Noises

These can happen when components inside your air conditioner start to get loose. They can knock around or vibrate and create a banging noise that stands out from your AC’s normal operational white noise.

Preventative maintenance helps by assessing each component in your air conditioner and where it is. If it looks loose or out of place, a technician will address the problem so everything stays exactly where it’s supposed to be. It’s not uncommon for you to run into this problem, but it’s one that definitely needs attention.

Metal Screeching Sounds

Metal components require lubrication to work with other metal components. Without lubrication, you get this awful wailing sound that really stands out. This problem is huge because your AC is encountering unnecessary tension as a result of friction.

While this isn’t indicative of a breakdown, it can escalate to that if left unchecked. Maintenance helps because we re-lubricate these components during your annual appointment. Lubrication can dry up over time, so it’s important to keep things running smoothly.

Clicking That Isn’t From Your Thermostat

Ever turn your AC on and hear a clicking sound coming from your thermostat? That’s supposed to happen, but it shouldn’t continue from that point. If the clicking persists, it might be coming from, well–anywhere in your AC that has electricity. That’s not really narrowing it down much.

When we perform annual maintenance, that includes testing different components to make sure they’re not using too much power or have any issues drawing power in the first place. That usually prevents clicking noises, although components can fail at any point between your maintenance appointments.

Prevent Those Odd Sounds

Annual maintenance is preventative–it stops problems before they happen. While it’s not perfect and there’s no telling what stress your AC will go through during the year, annual maintenance helps give it the best fighting chance for everything it will encounter. If you don’t already have an annual maintenance service scheduled, now’s the time to get started.
