Abstract: Provided are a method and apparatus for reducing a refrigerant pressure difference within an HVAC system having a controller, one or more compressors, and at least two paths of refrigerant piping comprising alternative paths for refrigerant flow through the HVAC system. A valve is coupled to each refrigerant piping path for permitting, or preventing, refrigerant flow through each of the alternate paths of refrigerant piping. The controller may open at least one valve for a defined period of time in response to a triggering input to allow a refrigerant pressure difference within the HVAC system to dissipate across the opened valve.
