AC tune-up one system. Filter was clean upon arrival. Drains were having issues. Ron declined the quick blast and said all other technicians used with solution. Drains seem to be flowing good after I treated it with drain solutions. Everything else is at manufacturer specs at this time.
Customer has a 2015 single stage gas trane system with properly insulated attic with radiant barrier and ducts all mastic sealed with clean ducts .only recommendation I had after completing ac tune up is a float switch . (Customer wants to do that himself )
