Don’t Ignore that Hissing Sound Coming from Your AC

During the hot summer months, homeowners in Little River, SC put their AC systems through the wringer. To make matters worse, they tend to ignore strange sounds that their air conditioners make. Oftentimes, these noises are early indicators that something is wrong. Of all the AC sounds you may hear, one of the most common is a hissing sound. Let’s talk about why your AC system might be making a hissing noise and why you should call a professional for AC repairs.

Refrigerant Leak

Typically, the most common cause of an AC hissing sound is a refrigerant leak. Other times, this hissing noise can sound more like a bubbling noise if it is a leak. This kind of leak can be very bad for the ozone, especially if your unit is old. Some common indicators of a refrigerant leak include ice buildup on the AC unit, rising energy bills, and vents not blowing out cold air.

High Pressure in the Compressor

The compressor in your AC unit is pressurized. This is normal, but it can start making a hissing noise if there’s too much pressure. When this is a problem, you will probably notice the hissing for around 10 to 15 seconds after your AC unit turns on. Also, your system might start and stop more often than usual. Getting this fixed quickly is important because the extra pressure can damage the compressor.
