I Hear a Hissing Sound from the Air Conditioner – What’s Happening?
Any time you hear unusual sounds from your air conditioner, that’s a sure sign it’s time to call for professional service. If you need a reliable system that will get your home to the desired temperature quickly and efficiently, all parts of your air conditioner must be in proper working order. Not only are your energy bills at risk of increasing, components of your system may begin to fail and require costly replacements. A sure sign you have a problem: loud or strange noises. Take a moment to listen to your AC…one of the most serious of these noises is hearing a hissing sound from the air conditioner.
What Causes a Hissing Sound from the Air Conditioner?
But the reduced cooling capacity is only a part of the problem.
Other components of your air conditioner must work extra hard to keep up if refrigerant levels are low, which means those parts may wear down sooner than they’re supposed to.
What if I hear a Shrieking Noise from my AC?
Another issue that could be causing the hissing noise is from the compressor malfunctioning. If pressure inside is too high, you could face some serious problems. And if the hissing sounds turn to a shrieking noise, turn off the AC immediately and call the HVAC technicians at Lawes to find out what’s wrong and how to fix it.
What If It’s My Heat Pump That’s Hissing?
If you have a heat pump, the hissing noise could be coming from your reversal valve. Because this valve allows refrigerant to flow in the opposite direction, a heat pump is able to heat and cool your home. If this part is malfunctioning, professional repairs can diagnose the problem.
When Hissing Sounds Aren’t a Problem
Everyone’s air conditioner has normal operational sounds, one of which may be a short hissing noise due to refrigerant expanding in the expansion valve. As long as it only lasts a few seconds and then goes away, it shouldn’t be a concern.
