Installed a Carrier 25HBC5 two-zone ductless mini-split air conditioning system in a residential home. Mounted the outdoor condensing unit on a concrete pad using Rubber-A-Mounts for vibration isolation. Ran two separate linesets of 3/8" liquid and 5/8" suction lines through exterior walls using LineSet Cover line hide. Installed two 9k BTU wall-mounted indoor air handlers in the living room and master bedroom. Evacuated the system to 500 microns using a Fieldpiece EVAC4WAY vacuum pump. Charged each zone with 24oz of R-410A refrigerant per manufacturer's specifications. Programmed the Carrier Infinity System zoning control board for optimal comfort and efficiency.
