    You have to remember though with a warm box and high suction pressure you're going to be running higher than normal head and your condenser may not be in the perfect shape as it was new.


    How old is this equipment?

    Is that low end Carrier equipment ? Probably has no head pressure control for low ambient conditions. Just fan cycling.

    In my opinion the suction pressure is too high. I work in the Houston area. I have seen freezers that would not pull down on a hot day when the condensers were on the roof. Even though the suction pressure would be close to normal the freezer wouldn't pull down. I think the condensers were minimal capacity and couldn't reject enough heat when they were on the roof.

    What model number do you have ? RDI does make a 120 series for high ambient conditions. They come with a larger condenser.

    suction pressure is to high to be a txv.suction pressure would have to be below 10psi to feed enough liquid to raise discharge pressure.
