Question about Goodman CLQ36AR49 Air Conditioner
I changed out r22 condenser unit , I installed a used working trane Xl-13 . I have 150 psi on high side port and little to zero pressure on low side test port. Is it possible that trash could be against low side service valve. Or incompatibility with air handler and condenser unit? It was around 70 degrees outside

I would suspect the valve on suction side not open. if the other system failed on a burn out you could have a blocked dryer or orfice at coil.

It sounds like you are low on charge. I think you have a thermostatic expansion valve and you need to check the subcooling, you should have 12 to 15 degrees at 95. At 95 degrees your head should be about 280# for a 12 or 13 SEER unit or higher depending on the effeciency. At 78 to 80 degrees indoor depending on the humidity, that is normal. The valve will open to try to fully feed your indoor coil and it sounds like your head pressure is to low to force enough refrigerant thru the coil.

I believe He is talking about the suction pressure, not head pressure which runs much higher, he's likely correct but this symptom could be due to several things, discuss it thoroughly with your service provider

I'm new at this and I can't tell how old the post is but I'll contribute anyway.
You probably have fixed the problem by now. I wonder what part of the system is freezing up. I don't have a lot of experience but I know you can get frost where there is a restriction in the freon. If the freon line filter near the outside unit has frost on the house side the filter is partially plugged. I have also seen fost on the evaporator (attic "A" coil) when there is a shortage of return air flow. You could have a plugged filter or colapsed return duct, or even an "A" coil with a lot of dust covering and plugging the fins. I guess restrictions in your room air supply registers could cause the problem too. Maybe you have most of the vents closed off to save energy. Just some possibilities.
