RUUD 2 ton UAKB 024JAZ condenser with Appolo SA 3024 air handler. Air handler came with .059 piston. Condenser compressor ran quiet as a mouse for 4 days and now its making a racket.
RUUD manual piston chart shows 57 piston when mated to RUUD air handler.
Is 57 the same as .057??
Is .002 enough difference to make any difference??
Im at a loss and local heating and plumbing company blamed the .002 as soon as I questioned it. I think theyre stupid.
Im more inclined to think non-condensables?? Evac, pump to 500 microns and recharge. If that doesnt work replace compressor.
