    Yes First thing I did was clean the coils and check the fans. I'm going to nitro the condenser and evap and get a new drier and cap tube and hope its not the compressor

    True boxes seem to have an issue with clogged cap tubes I replaced one once that was so clogged it was pulling a vacuum on the suction side pulled the cap tube full of black stuff

    I just run a zip screw in and out of the stub making a new hole for the replacement cap tube and then sweat a little braze on the old tube that i cut off. I never understood why true crimp's the evap inlet. Especially since they know their product is notorious for clogged cap tubes. Idiot's!!!!

    Practice with the torch my friend. I agree a garbage design, and True never gives you any room to work either.
