Re: Checking R410a Charge on Heatpump in Cold Weather
Normally you would run it in cooling mode and put a restriction around the outside condenser. Something like cardboard... The air restriction will cause your head pressure to rise up enough to make subcooling accurate. 2 ounces won't make any difference but a pound either way could.
 Changed evaporator to condenser...
