What is the norm for the ac compressor to cycle on/off? Mine seems to kick in for roughly 1-15 seconds, then off, then on again. I just got it back from the shop, new everything. Mechanic claims it is properly charged, but, it just doesn't get as cold as I think it should be. I haven't measured the temp at the vents, but I can definitely say that it isn't "cold"..... cool yes...."cold" no. Now at night time, it gets ice cold! Oh.... also, the temps down here in Coastal Georgia have been averaging triple digits, sometimes, high 90's.
