On a properly-charged and working air conditioning system using R-22 refrigerant. Low pressure refrigerant switches on Carrier HVACR typically open at 50 psi and close at …Running and maintaining the system will be cost-friendly as the unit doesn't consume a lot of electricity to cool a space; Since R454B performs better than R410A, it's a more energy efficient refrigerant. You'll need a lesser R454B charge within a system than when using R410A. This lowers the cost of running a system with the refrigerant. Absolutely there is pressure in the air conditioning or heat pump system when the compressor is not running. When the compressor shuts off the high side pressure is high - say 200 and the low side low - say 20 (these are just conceptual as actual pressure depends on the compressor, ambient temperature, refrigerant type).
