Customer also paid today’s plumbing repair on this invoice. $75 is for no worry AC warranty. I recovered refrigerant charge, removed indoor txv and carefully installed new valve in attic. Pressure test and leak checked new txv and then while flowing nitrogen welded in a liquid line filter dryer. Pressure tested and leak checked again with nitro. Pulled system into deep vacuum and then recharged with new r410a 10lbs.
