Sounds You Shouldn’t Hear Your AC Make

woman-with-hand-to-ear-to-listenDo you hear odd noises from your air conditioner? If your unit is old, then some noises are to be expected. For example, you will hear the compressor start up. You may also hear the gentle rattling of ductwork. However, there are other sounds that are not normal and could hint at an underlying issue. 

Here we discuss some of the most common sounds that you may hear from a malfunctioning AC unit. Knowing about these sounds can help detect a problem early and get in touch with a professional for air conditioning repair in Edmond, OK. They can diagnose the issue before it causes too much damage to your AC and help you avoid costly repairs. 

Hissing Noises 

If you hear hissing noises from your AC, this could indicate a refrigerant leak. This leak can occur due to a crack or hole in a coil that carries the refrigerant. It can lead to inefficient cooling. The coolant being emitted can also prove harmful for the inhabitants of your home. 

Screeching Sounds 

If your unit produces a high-pitched screeching sound, this could be because the lubrication has worn down on the motor bearings, and they have gotten damaged. These noises may also result if the belt that connects the motor to the blower slips. If you hear such sounds, it’s important that you turn off the air conditioner immediately and call a professional for AC repair. 

Banging Noises 

Banging noises are never a good sign. They typically suggest that a screw or bolt has come loose inside the AC unit and is moving around. It could also indicate that the fan blades are wearing down.

In some cases, banging noises can occur due to problems with the compressor too. A compressor distributes refrigerant to different parts of the HVAC system and removes heat from your home. As the compressor grows old, some parts can become loose inside, leading to the banging or rattling noise you hear. We suggest getting in touch with a local professional for HVAC repairs to identify the problem because the detached components cause any other damage to the unit. 

Buzzing Sounds 

If you hear a buzzing noise from your AC unit, it could be because of unbalanced fan blades in the outdoor condenser unit. They can also result from dirty condenser coils, the fan motor malfunctioning, or a blockage near the copper lines that connect to the AC unit. A HVAC repair professional will be able to take a look inside the unit and identify the source of the sound to repair it.
