Summer comes early in Georgia, but the spring can still be an unexpected time to need AC repair services. However, this often happens during the changing seasons because the air conditioner hasn’t been used in so long. Fortunately, there are often audible clues about imminent issues. If your AC unit is making strange noises, use this guide to decode the meaning behind them and take care of the problem before it becomes a major headache.

Common Sounds That Require AC Repairs

1. Buzzing

Cooling and heating contractors often find that a buzzing sound while the unit is running is caused by a frozen coil. This happens when the airflow is diminished, which often causes condensation to freeze on the coils. If it’s not fixed, the AC won’t be able to cool the air effectively, may start to leak, and will increase the energy bills as it struggles to keep up with what the thermostat is asking for.

2. Hissing

When the unit’s making a loud, high-pitched hissing or screaming noise, it’s best to shut it down immediately until a cooling and heating company can inspect it. This noise is usually caused by malfunctioning compressors or issues with the refrigerant, such as a leaky hose. Without the required repairs, this can completely break the compressor, which is the most expensive part to fix.

3. Squealing

If you hear this sound and have an older AC unit, it’s usually caused by the internal belt slipping out of alignment. You may be able to hear it both inside of the home and outside near the compressor.

For newer models that use direct-drive motors to draw air across the condenser coils, the culprit is typically poorly installed bearings on the fan’s motor. If an AC repair expert doesn’t fix the issue, the belt can come completely undone or the engine can break down.

4. Thumping & Clanking

It’s recommended to turn the AC off if you hear either of these noises because it’s usually the result of something coming loose in the condenser unit. It may be as minor as a loose bolt, but it could also be a broken fan blade. The latter may result in damage to the condenser, so contact a technician to be safe.

5. Clicking

When the air conditioner makes a continual clicking noise while in operation, it’s a sign the electrical parts aren’t working. Typically, it’s caused by a faulty thermostat. Unless you replace the thermostat, the system may not operate efficiently and could lead to increased wear and tear on the system.
