I am having trouble getting cooling performance out of my brand new Trane units inside and out (installed in November, so quite new).
I have outside:
Trane 2TWX4018A 1.5 ton
I had an service man over today and he told me that he thought the units were mismatched, because the refrigrant levels (or actually the pressures and temperatures that he used to look up the level on a curve) measured outside seemed a little high but inside seemed a little low. So my question is, are these units matched okay to one another? Is it okay to use them in conjunction?
My problem is that I can't seem to get my house cooler than around 73 degrees, when last year before the replacement my house got cool very quickly (1000 sq ft condo, not a big place). Obviously the serviceman checked the coils for dirt, and he checked the refrigerant, but got the readings saying it was too high one place and too low the other. It does use a TXV bulb to restrict the refrigerant flow (I think that is what it does), could that be the problem?
A complete novice...
