Good evening. Question for the knowledgeable (there seems to be many here): Evap coil on the house went bad, had new coil/furnace installed. Higher heat, ac unit will not cool. Evening comes, and ac blows cool. AC guy said compressor is bad, but if compressor is bad, should be all the time right? Outside units is a RUUD AUFD036JAS, Design pressure H - 300psig, Dsn Press. L is 150psig. New evap coil is a Rheem RCFA HM3617AC, says 550psi. Are these systems mismatched, causing my ac not to cool in higher heat conditions? AC guy tried the parts replacement troubleshoot method, my experience with old cars says ineffective and expensive way to fix. Any words of wisdom? Thanks. Bob.
