Air Conditioning Repair Guide: What’s That Hissing Sound?

It won’t be long until we are turning on our air conditioners again, and one thing every homeowner should do, especially at the beginning of the season, is stay aware of signs of potential problems with your AC. One way your AC system will communicate problems is through strange sounds. As the homeowner, you are familiar with the normal operational sounds of your air conditioner, so when you hear something that doesn’t sound quite right, it’s usually an indication that a problem has developed. One such sound of which to be aware is a hissing noise. Hissing noises can indicate a couple of problems, and both require the help of a trained and certified expert. The AC professionals at AAction Air can assist you with all of your air conditioning repair needs in Savannah, so call us today!

Nope, It’s Not a Snake in Your AC

So why is your system making a hissing sound? The first potential reason is that a refrigerant leak has developed. The refrigerant in your system is under pressure, and when a refrigerant leak develops, the pressurized air can escape through the hole or crack along with the refrigerant; this creates a hissing noise. You may also hear a bubbling sound and see bubbling if the leak area is visible.

The second reason you may hear a hissing sound is that the compressor is operating at a pressurization level that is too high, and as such, air is escaping through any available space. This is a dangerous situation as the compressor can blow if allowed to continue operation, so if you hear the hissing sound coming from the compressor, turn your system off immediately and call for an expert.

Any time your air conditioner makes an unfamiliar sound, it’s always best to call for a professional.

The AC specialists at AAction Air are here to help 24 hours a day, 7 days a week, so if you are experiencing issues with your air conditioner, call us today.
