Exactly. Low refrigerant or low air flow are about the only thing that will cause coils to freeze. I just replaced two condensers last month. The old units were beautiful two stage 18 SEER units given to me by my employer. Unfortunately, they were early high efficiency models with complex control boards and early ECM motors. Things are simpler now and hopefully more reliable. Because I was paying for them I bought 16 SEER single stage units. The price difference was significant. In hindsight, the SEER rating is fine but I miss the dual stages which really wrung the humidity out of the house much better that these do. Oh Well.
