Ice on My Ductless Mini Split

Green8 · Jul 20, 2018

Why does ice form in a ductless split AC? I have three wall-mounted a/c's running off one outside unit. Everything is working fine however. They still cool great. Any reason for concern?

Not sure, but when that happens with a car A/C, it usually means the freon level is low.

Thanks Gary, a friend of mine is having this problem.

Try cleaning the unit...dust may also be the culprit

Where's the ice forming, inside, outside.

Coils, outdoor unit.

Is there a chance the controls are accidentally stuck on something other than cool ?

Not unusual for this to happen in winter , when in heat pump mode . Ours have a dry mode , but have never used it .

Typically , low refrigerant will cause icing on the indoor coil , when running A/C mode . Not on the outdoor unit .

I would power it down , wait a few minutes , power it up and see if it persists .

I do not know id a " stuck " reversing valve would cause it ?

Best of luck to you ,

Wyr
God bless
