Complete: 2 systems worked on DS. HO was concerned with temp not meeting Tstat. Found system seemingly a little over charge. Just adjusted a little best I could get at the AH was a 15° split. 48 degree supply air. Everything seems to be working as good as the system can give for its age. She’s trying to keep temp at 67-68 at night. I told her she needs to keep it if possible between 71/73 at night if possible. System is working as it should at this time.
