Low lifts will improve both efficiency and capacity, as long as the system is set up properly. Google the BTU specs from the manufacturers of various compressors at different temperatures. I recommend a thermostatic expansion valve, TXV, instead of the cap tube your donor unit probably uses. Cap tubes are great under a specific set of circumstances, but TXV's compensate for varying conditions and can be adjusted for optimal operation without tearing the system open. Fee-bay and Surplus City Liquidators are great sources for parts.
