Any AC Techs

I converted a Ford Ranger years ago. I put a fan on the condensor and a high pressure cut off switch in it. It was explained to me that during extended idleing the pressures could climb causing issues. Truck idled for over an hour and pressure did not move, so I think the pressure switch was a waste. My vent temps were in the high 20's -low 30's in the heat of summer in AZ....
