I have a Goodman 13 SEER HP with a varible speed air handler,
The evap has a TXV. During heat mode what is the best way to charge the system. Th mfg instructions recommend hot gas charging ( outdoor ambient + 124 deg) however it doesn't designate this method for TXV. On fixed bored I have always followed this procedure. (OA + 115) on 10 and 12 SEER. But just wondered if subcooling should be used with TXV? Thanks for the help. BTW the reason for the question is when charged under hot gas method the actual suction seemed quite low given a 44 degree OA. Maybe just had brain lock since it was Saturday and I was 275 miles from home trying to help a friend.
Thank You for your help.
