Most of today’s air conditioning units are designed to run as efficiently and noiselessly as possible. Whether you rely on central or ductless AC, it can be unsettling to hear strange sounds coming from your system. However, if you understand these noises, you can determine what might be causing them and find a solution. Here’s a more detailed look at some common noises and their causes.

Noises Your Air Conditioning Unit Might Make & What They Mean

1. Banging

If you step outside, you may hear banging noises coming from the outdoor unit. This usually indicates that a part has become loose within the blower component. When this happens, the motor struggles to work and experiences unnecessary stress. If the problem is ignored, you may experience a complete system failure. To avoid this, call an HVAC contractor right away to repair your blower.

2. Humming

Whenever you hear a humming noise, it’s most likely caused by electrical problems. Loose wiring often triggers the noise and should be repaired as soon as possible. Additionally, this sound may indicate that loose parts or refrigerant piping have begun to vibrate. It’s not always easy to tell what’s causing this noise, so you should have a professional take a look at your system for a reliable diagnosis.

3. Metallic Clanks

Clanking sounds often indicate failure of internal parts. For example, the compressor may have become loose and require a replacement, or your blowers and fans may have become unbalanced. If you hear this sound, replace the broken or loose components as quickly as possible. Otherwise, you may face increased repair costs in the future.
