Ductless mini-splits can keep things cool when the temperature rises in Lillington, NC, even during the hottest days of the summer. In addition to being efficient, they are usually whisper-quiet. If you hear these unusual sounds coming from your ductless mini-split, a professional can help you resolve the issue.
Hissing
Refrigerant allows your ductless mini-split to absorb heat from inside your home and send it outdoors, thereby cooling your place. If your refrigerant line has a hole or crack in it, refrigerant will leak out, and this could result in a hissing sound. Without adequate refrigerant, your mini-split will have a hard time meeting your cooling needs.
Gurgling
Gurgling could also indicate a refrigerant leak. When the refrigerant leaks out through a hole in the line, air could enter the line. As it travels through the system, it could cause a gurgling sound.
Grinding
You may need new bearings if you hear a grinding noise from your ductless mini-split. Bearings play an important role since they minimize friction and can enhance efficiency.
Bearings can wear down over time or become damaged due to dirt that gets in your system. When this happens, you’ll want to get them replaced as soon as you can.
Buzzing
A high-pitched buzzing noise may indicate an issue with your electrical components. In addition, it could mean that some internal parts have come loose and are vibrating when the ductless mini-split is working. To prevent major problems from arising, call for AC service from our professional technicians whenever you hear buzzing.
You can expect your ductless mini-split to operate quietly. If it starts making hissing, gurgling, grinding or buzzing noises, you should get it checked out. Call Cape Fear Air, Electric, & Plumbing to schedule a ductless mini-split repair.
