Performed the installation of a new 1.5 ton Liberty air conditioning system following all manufacturer specifications. I started by setting the air handler and connecting the refrigerant lines using nitrogen purge and proper brazing techniques. The condensing unit was positioned on the pre-fabricated pad with proper clearances. I pulled a deep vacuum on the lineset, then charged the system with the required amount of R-410A refrigerant. All electrical connections were made at the disconnect and thermostat for 208/230V operation. Upon startup, I verified that the system was operating within the recommended superheat and subcooling parameters to ensure optimal cooling performance.
