Report "This is a weatherking central air conditioner. Had been looked at by another person before me. Wasn't cooling right is all the information I had. When I walked past it one day (this is at a golf course), I noticed the suction line going into the condenser cabinet was iced up. First thing I thought about was maybe it had to much freon in it. After looking into it further I noticed it was iced up all the way to the compressor. When I had a person turn the t-stat down to turn down, the head pressure went up very fast. It was up to 450 psi before i could get it turned off. I have worked with this unit for the past week and haven't had any success. It did have to much r22 in it. I have tried varying the the high and low pressures by adding or taking out freon several different times with no success. Sometimes the air coming out of the condenser feels warm and sometimes it barely puts out much heat. This is with the same charge in the unit. Cond. coils have been cleaned. Right now the supply temp. is about 70 degrees and inside temp. is 75(oat 80-pressures are 230 & 65. I can barely get a look at the evaporater coil, but it looks to be sweating well. Sometimes the drain for it has a stream of water and sometimes it doesn't. I think it depends on how the condenser is operating. The suction line coming out of the a-coil cabinet is cool to the touch, but it usually feels cooler going into the cond. cabinet"
