Hey guys, Trying to determine whether or not I have a faulty compressor. Possiblly bad valves??
I have a 2.5 ton York condensing unit model (030) and matching indoor coil, 12 years old (estimated). R-22; metering device is an orfice. I think #63 (don't quote me) 25ft line set length at most from furance to outdoor unit
Ambient 95 degrees...
I have an 82 lb suction; 200 lb head; 59 degree suction line at compressor about (-3 superheat) and 98 liquid line about (-3 subcooling).
Compressor RLA= 13.8 Currently running at 10.3
I am only getting a 13 degree temp difference. (supply air-56) (return air -69)
I noticed that the liquid line is rather small. I think it is a 1/4 instead of 3/8tubing. Does this play a role in these readings?
Can't do any better than the 13 degree TD????
