Should My Ductless System Be So Noisy in Jacksonville, NC?

Ductless mini-splits shouldn’t make any loud or long-lasting noises. If the system in your home in Jacksonville, NC, is doing so, it’s a safe bet that it’s in trouble. To help you solve this issue, here’s some information about a few ductless HVAC noises and their meanings:

Hissing

Under no circumstances should you ignore these noises. When coming from your mini-split, they nearly always indicate a refrigerant leak.

If gaseous refrigerant escapes from a hole somewhere in your system, it’ll make a hissing noise as it flows out of that opening. Due to the pressure changes that this will cause inside your system, you may very well hear a sharp whistling noise as well.

Refrigerant is highly dangerous. Inhaling even a small amount of it can be hazardous to your health. Therefore, if you hear these noises and suspect there’s been a leak, evacuate your home and ask HVAC service technicians to handle the problem.

Rattling

The two likeliest explanations for this noise are loose components and stray debris. The former might include nuts, bolts and fan blades that aren’t as tightly fastened as they should be, and the latter might entail that some dirt, acorns, pebbles, twigs and other small objects are tumbling around inside your system. HVAC maintenance service technicians can fasten loose parts and clean out debris for you.

Humming

It’s normal for your mini-split to generate a barely audible hum throughout its operations, but if the noise becomes loud or jarring or if you also hear a buzzing sound, you should suspect that something has gone wrong. In all probability, there’s some kind of electrical issue. Since it’s difficult to precisely diagnose these, professionals should examine your system.

Your ears can alert you to some serious problems with your ductless mini-split. Don’t hesitate to trust them. If you live around Jacksonville, NC, call Gideon Heating & Air Conditioning to ask for our ductless mini-split services.
