I would take a look at indoor TXV make sure it's a bi flow. I had one were they ordered and installed a non bi-flow and had same problem cuz discharge from compressor was beeing blocked at indoor TXV. If the part # on indoor TXV checks out to be bi-flow then check outdoor TXV by placing bulb in hot water wich will open valve reduce liquid pressure and increase true suction press. If that doesn't show any results try the same thing inside. Of corse while inside also check for clean coil and filter. Good luck would like to see what you end up finding

When you look at the forums there is an open area and a locked area. Once you have been approved by the committee you will have access to the locked forums, these are the forums where in depth technical help is exchanged from one pro to another. This(locked pro forums) is also the area of the site that is priceless, you can easily learn more there than most anywhere else you have received training, don't be scared to ask questions.
You also have to be approved to post in the AOP(ask our pros) forum. This area is for home owners to ask for advice and opinions from pro members. Be careful about reading what forum you are in because if you post repeatedly in this area(AOP) with out approval you get a "timeout".
