Troubleshooting Your AC: Strange Noises and What They Mean

It can be frustrating when you hear a strange and unfamiliar noise coming from your AC. A normal functioning AC should be virtually silent, with perhaps some gentle humming or soft buzzing in the background that’s barely audible. Any strange or loud noise coming from your AC is a red flag and typically indicates something is wrong.

You’ll want to diagnose the issue and determine what is causing the noise to determine the best course of action and resolution. In this article, we’ll discuss what types of noises you might hear, why it’s happening, and how to go about fixing it.

What Types of Noises are Most Common?

When your AC starts making strange noises, it can range from a loud rattle or banging to a low humming. Most likely, you will hear something that you’ve never heard coming from your AC before. Let’s talk about some of the common sounds you will hear and what it means for your AC.

• A loud or persistent grinding could indicate that you have a failing motor or compressor. A motor or compressor acts as the “engine” that drives your AC system, and it has several small moving parts. If these parts aren’t lubricated regularly and the motor isn’t kept in optimal condition, the parts could start grinding together resulting in a loud noise.

• A continuous buzzing noise can be a gateway to a number of AC problems. It can be a sign of a malfunctioning capacitor, which is a part of the system that helps turn on the AC’s compressor. If the capacitor isn’t working correctly, it can result in a buzzing that indicates it needs to be replaced.

• A clicking noise is rarely something you need to be concerned about. Generally, this will mean a part of the system needs to be recharged or a part is loose. This can also be an indication of a problem with the thermostat or air handler, which controls the AC’s fan.

• Screeching is usually a sign of a failing blower motor. The blower motor helps control the fan that circulates the air throughout your entire home. If it’s failing, it may produce a loud screeching sound that’s very noticeable.

Why is my AC Making a Strange Noise?

In most cases, strange noises are the result of some kind of mechanical failure. The system could be ill-maintained, parts will begin to wear down, or a part could just malfunction due to age. A strange noise can occur from something as small as an object stuck in a fan or from something major like a failing motor.

No matter the underlying cause, a strange noise is often the result of an internal issue that needs to be addressed immediately. The longer you let it linger, the worse it will become and the greater the chance you might need to replace the entire unit.

What Can You Do To Fix The Problem?

If your AC is making a strange noise, the first thing you should do is turn it off and unplug it. Then, contact a reliable and certified technician who specializes in AC repair. The technician should be able to diagnose your AC and identify the root cause and repair the issue quickly and safely.

Some common repairs include replacing the compressor, repairing the thermostat, replacing the blower motor, or lubricating the parts. Depending on the repair, it could be relatively easy and inexpensive, or it could be a major cost.

Why is my AC Making a Strange Noise?

In California, there are a few key recommendations from both HVAC technicians and local appliance companies that can help you proactively prevent any strange noises from coming from your air conditioner. Below we will outline the main reasons why air conditioners in California can start making strange noises, and what preventive steps you can take to avoid any of these issues.

Check for Dirt Build-Up

One of the most common causes of strange noises coming from your air conditioner could be due to a buildup of dust and debris. Over time, any dust, lint, pet hair, or other debris can accumulate in the cabinet of your air conditioner, creating a blockage to airflow. This can cause the fan to be forced to work harder, which can cause strange sounds. Checking your air conditioner regularly and ensuring that the filter and inside of the cabinet of your unit is free and clear of any dirt, dust, lint, pet hair, or other debris can help reduce the chances of experiencing any strange sounds coming from your air conditioner.

Listen For Unusual Fan and Compressor Noises

Another common factor to look out for when it comes to the air conditioner occasionally making strange noises is the fan and the compressor. Fans are normally the most common culprit of a strange noise coming from your air conditioner. You may hear a rattling, grinding, or even squealing noise coming from the fan. If not properly maintained and taken care of, these noises can start to become more overwhelming and frequent. In order to avoid these noises, you should regularly inspect and clean the fan and compressor, ensuring that these vital parts of the air conditioner are in top working order.

Test the Refrigerant Lines

Refrigerant lines that are blocked or need to be repaired are another common factor when it comes to the air conditioner occasionally making strange noises. If air is not flowing properly, it can result in unusual noises coming from the air conditioner. In order to avoid any strange noises coming from your unit, you should regularly check and inspect all of the refrigerant lines, and if necessary, have them professionally cleaned and repaired if necessary.

Have the Unit Cleaned Yearly

Another important recommendation when it comes to avoiding any strange noises coming from your air conditioner is to have it professionally cleaned on a yearly basis. This can help keep the unit running smoothly and prevent any strange noises that may come up over time. By having the unit professionally cleaned, you can be sure that any dirt, dust, or debris that may have accumulated over the year has been removed, and the air conditioner is running as efficiently as possible.

Adjust Vibrations

Finally, it is important to occasionally adjust the vibrations coming from the air conditioner. Any weak or loose vibrations can cause the air conditioner to produce strange sounds. To help reduce any of these noises, you should regularly check the unit for any vibrations that may be present and make sure to adjust them as necessary.

Taking the right preventive steps will help ensure that your air conditioner in California is running as efficiently as possible, and that any strange noises that may arise are quickly taken care of and prevented from occurring again. Following the steps outlined above will help reduce the chances of your air conditioner making strange noises, and ensuring that it is running smoothly and efficiently throughout the year.
