Is there any downside to rapid cycling of the AC compressor? I believe that some AC systems do not like to be turned on & off rapidly, at least I'm pretty sure I've seen such warnings on home ac units... "Wait at least 3 minutes before turning back on". Or am I thinking of video projector bulbs? :-)
