Thirty plus years in the a/c repair business. I have a split unit in an apartment on 3rd floor of three. Pressures were to high. Acid washed condenser & evaporator of this 1 /2 ton Goodman unit. Pressures perfect. Output air won't go below 72 degrees. Both apartments on each side, same floor deliver sixty degree air. I recovered refrigerant and weighed in exact amount of R 22. Same results. I have never had this problem before. I have to be missing something. Compressor amps good. Any help would be appreciated. This unit has got me not sleeping at night. Thanks for any help.
