What's going on with my coils?

So I obviously have a problem here - parts of my coils are icing up! But why just a few? I have replaced my filter, blown out the drainage line, so I suspect it's low on freon. The thing is - it used to completely ice up, and now it's just parts of it, is there debris in the line maybe? Thanks!

RE: What's going on with my coils?

Icing usually starts closest to the refrigerant metering device in the system (orifice or TXV valve) and progresses from there on the vapor line back towards the condenser.

That is the first spot refrigerant boils from liquid to gas and absorbs the most heat (producing the lowest temperature).

A low charge is a very common cause.
