    trane GEH water source heat pump

    hey guys, looked at a trane geh water source package unit today. hanging above a finished cieling with no access. unit had leak, and apparently hadn't been used since last summer due to leak. found leak in pipe, soldered up, evac, wieghed in charge. had 90-100 psi suction, 240 high side, and hot air coming out in cooling. thinking reversing valve stuck midway, bypassing a little hot gas to suction? will test line temps to check for leak by. do these coils energize for cooling? is it worth trying to un-stick valve by tapping on it, or any other tricks. thinking it's from sitting empty for 6 months.

    r-22 about 12 years old. do not want to remove unit and change valve, but will probably have no choice.

    ya but blowing hot air in cooling mode. i thought stuck 4 way could be leaking into suction causing high pressure. dont you think high side would be lower with bad valves?
