Sounds to me like the AC don't have enough freon in it. What happens is when the compressor runs the pressure is lowered on the low side (inlet) and raised on the high side (outlet) if the low side gets too low it will freeze the moisture in the air around the fins and tubing. I have seen this happen many times on autos and home AC units. Have an AC person throw the gauges on it and run it full blast to check this out. Even a new unit can have a small leak maybe at an 'O' ring etc.
