Upon my arrival in Smithville, for air conditioning tune-up. We recovered all refrigerant, removed the heat transfer media coil for chemical cleaning, installed new voltage enhancement system, voltage distribution system, added performance enhancement system, broke down air movement system for chemical cleaning, redid wire terminals, chemically washed the condenser coil, replaced the refrigerant metering device and cleared the tree surrounding the condenser. We then reinstalled the heat transfer media coil, air movement system, replaced the filter dryer, purged with nitrogen while brazing and put the system under a nitrogen pressure test. After verifying the system is tightly sealed we evacuated the nitrogen and out the system under vacuum. We resealed the case coil to the plenum, replaced the comfort control wire from the condenser to the exterior wall, ran it inside liquid tight to prevent damage from the sun and wrapped new Armaflex around the suction line outside.
