A condensing unit which includes a base plate having first and second oppositely disposed major surfaces. The base plate may include flanges disposed along the outer periphery of the base plate. A compressor mechanism and a condensing coil are mounted to the first major surface which faces a first direction. The flanges may also extend in the first direction. The second major surface may be substantially free of projections and define a bearing surface for the condensing unit. The motor of the compressor may have a main shaft which extends substantially parallel to the first major surface. The compressor may be a rotary compressor. There may be a conduit in fluid communication with the compressor and condensing coil and define together therewith a fluid circuit. Valves rotatably mounted on brackets and in fluid communication with the fluid circuit and operably couplable to an evaporator circuit may also be provided.
