Your ductless mini-split won’t run silently. Pops and cracks are normal noises, and so are fan noises. However, there are certain ductless HVAC noises that indicate trouble with your system in Decatur, IL, so read on to learn about them.
1. Rattles
Most of the time, when you hear rattling, that sound is coming from the outdoor components of your ductless mini-split. The usual culprit is either something that has come loose inside the system or a foreign object has gotten inside.
Given how fast the outdoor fan turns, loose items can be both destructive to the system and dangerous to those around it. When you hear such rattling, have a professional technician take a look.
2. Hums and Buzzes
When your ductless mini-split runs normally, you can expect it to hum quietly. The kind of hum that indicates trouble is typically one that results from the outside unit drawing too much power. It’s also possible for the outside components to buzz loudly.
These electrical faults can be dangerous. They always require professional attention, particularly because they’re notoriously tough to find.
3. Hisses
When your ductless mini-split hisses, it’ll almost always be because of a refrigerant leak. If the refrigerant level is low, then your system won’t be efficient. It’s uncommon, but in certain cases, low refrigerant can actually damage your system’s compressor.
Because each of these sounds can cause damage, it’s important for you to shut off your ductless mini-split right away. That will both protect it from more damage and make it easier for one of our technicians to repair.
