HVAC Installation and Service Tips- R-410A Pressure When Off, How Far to Backseat Valves, Other Tips. This is about HVAC Installation and Service Tips. I go over how much Vapor Refrigerant Pressure there should be when the outdoor AC or Heat Pump Unit is off, the condenser high and low voltage wiring, how far to backseat refrigerant service valves, how to properly turn on the outdoor unit when servicing, how to sleeve lineset through a block wall, where to find the subcooling rating and type of refrigerant, and why to use a condensate water trap. Supervision is needed by a licensed HVAC Tech before doing this as Experience and Apprenticeship garners Wisdom and Safety.
