When you set up a system, in order to get it tweaked to max efficiency you have to check the superheat. It amounts to taking a number of pressure/temperature readings and adjusting pressure to suit (via adjusting the freon charge).
Checking the expansion valve (txv) is incredibly easy. Why it wasn't done is beyond me.
My suggestion would be to find a real outfit who knows what they're doing. Ask around and try to get an old guy who's been at this stuff for awhile.
900 bucks to change out an expansion valve is ridiculous, too. You're just not having any luck at all. Sorry, brother.
