Are Hissing Sounds A Sign That Air Conditioning Repair Is Needed?

Did you know that one of the most clever ways to tell if you are on the verge of needing air conditioning repair is to listen to your AC system? Your system may emit a variety of noises such as loud bangs, but a common sound that scares some homeowners is a hissing sound. This is a sound that can occur for a number of reasons. Strange sounds usually mean that systems need to get diagnosed by a professional. If you have neglected to get timely service appointments, you really need to take odd noises coming from your air conditioning system seriously. The following points will help you to understand common reasons AC systems make hissing noises.

Compressor

A compressor that is on the verge of malfunctioning will start showing signs by making a hissing noise. If the issue is not addressed, it will get worse. Eventually, you can expect your system to start making screeching noises. If this occurs, you do not need to operate your AC system regardless of how uncomfortable the temperature is. You can cause significant damage to your AC system that could result in costly repairs. 

Air Ducts

Leaky air ducts need to get addressed even though they will likely not cause any mechanical problems with your AC system. They can cause you to have higher energy bills. The hissing sound may also become a nuisance if you have to hear it on a regular basis. This is an issue that is usually an easy fix. A technician can replace the ducts, which can mean energy savings for you.

Refrigerant Leaks

Leaks can cause a number of issues. If a leak is ignored, it can result in damage to the compressor in the AC system if the refrigerant levels get too low. One telltale sign that a refrigerant leak is the cause of a hissing noise is the presence of ice on the refrigerant line. Some individuals assume that ice on an air conditioning unit is normal since AC systems are meant to cool homes. Ice is a sign of an issue that needs the attention of a professional. You must rely on a licensed HVAC contractor to repair your AC system and add refrigerant. This is because the law does not allow laypersons to legally possess or add refrigerant.            

An HVAC contractor is a good resource to use to determine the exact reason your system is making noises. They can make repairs or replace parts as needed.
