Help Help Help please. Live in a 2 story home built in 1998 in the mid-south. In the three summers we've been here we've had problems cooling upstairs every year. Year one, the upstairs coil broke- replaced. Year two- compressor rotted out (and downstairs unit, just out of warranty, replaced-- no complaints this year, works fine). This year, upstairs unit not cooling properly and very high humidity. All replacements have been with Ruud or Rheem products both upstairs (split system) and downstairs (package). Installer, when called this year, recommends installing an Aprilaire dehumidifier on the upstairs unit. Didn't sound right to me, so I called another company for comparison. The tech checked the freon level, said the freon was overcharged, probably because the coil and compressor are mismatched. Said his company no longer works with ruud/rheem because of their problems and won't do the repair (probably needs a new bulb meter valve thingy-- my technical term, not his). He says the problem is really the mismatch coil/compressor, not doing the whole job at once, and the poor rheem/ruud products as well as TXV. He recommmends replacement-- another chunk of change.
At this point, I probably agree that the problem lies in not replacing the whole unit at once so, what's the recommendation? Go ahead and replace? Do I have any recourse with the other installer who's now recommending a dehumidifier? Just eat the $$$$ we've already spent and finally get cool??? I can't believe the problems and the $$$ we're laying out every summer and I just want this nightmare over. Please advise.
