Greetings to all and kudos for an informative site.
I recently bought and had a new Goodman heatpump system installed. The installer is a retired HVAC contractor who is a friend and owed me a favor. On start up, the unit wouldn't heat but works fine in cooling mode. Cycling from heat to cool didn't help. Long story short, temp measurements across the reversing valve indicated it was faulty (about 30 degrees difference) and diagnosis was confirmed by the selling distributor of the unit. Goodman says that since warranty is parts only, they will only provide a new valve. I'm told that's an industry standard and it looks like we will have to repair Goodman's new unit.
Did I shoot myself in the foot by buying Goodman, or is it common for a new unit to be (partially)DOA?
