HI

I want to ask you guys if anyone have exp' with the york brand.
This unit have an orfice in the liquid line and from what i understand this orfice is for the heat cycle.

My Q is:
Did anyone expiriance any problems with HP during heating?
I'm talking about 350 psi on 70 LP (R-22)
During cooling cycle the pressurs are fine 50-200psi
the problem is only when heating.

now:
Last time I had this problem with another york unit i changed the RV and the preformance were better.
this time i also changed thr RV but still I'm getting around 320 psi
I cacked airflow,filters,ducts,charge
I'm thinking that maybe york had problems with those ducted splits?
I know that on heating usualy you get higher pressurs but this looks abnormal

If anyone can help that will be mutch apreciate.
Thank you
