The air conditioner’s air compressor system was installed on day 64.  The lines for the refrigerant and electricity were pre-wired to the outside of the house during construction for an easy installation.   The compressor is set upon an ABS plastic base that not only keeps the unit off of the ground, but will not rot, crumble or erode over time, leaving an even and level surface for the unit.    As you can see from the photos above, the electrical panel connects to the compressor inside a piece of exterior grade shielded conduit.  The coolant line is insulated to prevent transmission losses as much as possible.
