Is Your Air Conditioning Noisy? Discover the Common Culprits

Your cooling system is meant to make your space more comfortable and be relatively low maintenance. Most modern air conditioners now include advanced technologies that dampen the sound of their operations, ensuring that noise levels stay manageable.

But if your HVAC unit makes loud noises before, during, and after completing a cooling cycle, this could be an indication of a potential underlying problem in your system.

This guide will highlight some of the most common noises your air conditioner may be making, what they mean, and how to fix them.

Common Noises an Air Conditioner Makes and How to Fix Them

Here are some common noises your HVAC system might be making:

Squealing

If your unit is making screeching, streaming, or squealing noises, it could be an indication of a bad fan motor or fan belt being broken or worn out. Also, it could mean that more than average pressure has built within your compressor that needs to be fixed ASAP.

A higher internal pressure within the compressor normally triggers a sensor, causing your AC to shut off automatically and make strange sounds.

If any of these problems arise, turn your unit off immediately and call skilled HVAC technicians to avoid potential explosions.

Clicking

If your AC makes a single click when you turn it on, there is no need for concern. However, if your air conditioner makes multiple clicks, it could indicate one of the following issues:

• Electrical or compressor failure
• Fan obstruction

If you have experience cleaning your outdoor units and the proper tools, you can clean the fan obstructions yourself. But you need professional assistance to identify and fix electrical and compressor issues.

Buzzing

If your cooling unit is making a loud bussing noise, it could be a sign of the following repairs:

• Faulty capacitor
• Obstructed copper lines
• Isolation feet
• Contractor malfunction

If any of these repairs are ignored, it can result in costlier damage and even electrical explosion. So, make sure to call licensed HVAC technicians to avoid potential hazards immediately.

Hissing

A loud hissing noise coming from your cooling unit could be a signal that your system has a refrigerant leak. Since refrigerant is a controlled chemical that is highly dangerous, it is advised to call experienced technicians to inspect your system and diagnose the problem.

Banging

A broken compressor or imbalance fan motor can cause your air conditioning unit to make loud banging sounds. Replacing these components can be costlier. So, consider getting help from professional HVAC technicians to get possible considerations.
