This project involves the complete replacement of commercial HVAC equipment, including the removal and disposal of existing units and refrigerant. The work requires modification of existing ductwork, installation of a Ruud 4-ton air handler with electric strip heat, and a Ruud 2-stage 4-ton heat pump on a preformed pad with proper drainage and electrical connections. Additional tasks include installing an easy-access air filter, new electrical disconnect and conduit, flushing and testing refrigerant lines, installing condensate overflow protection, and setting up a digital thermostat. The project concludes with system start-up and operational verification to ensure optimal performance.
Recover and properly dispose of all refrigerant from existing HVAC equipment in compliance with environmental regulations. Safely remove and dispose of the existing HVAC units. Modify the existing ductwork as necessary to accommodate the new equipment. Install a Ruud 4-ton air handler equipped with matching electric strip heating. Connect the air handler to the existing electrical supply and condensate drainage lines. Install an easy-access air filter on the return air duct leading to the furnace for maintenance convenience. Set up a Ruud 2-stage 4-ton heat pump unit on a preformed pad within a protective cage, ensuring drain legs are properly installed. Install a new electrical disconnect and conduit at the condensing unit to meet electrical code requirements. Flush the refrigerant line set, perform pressure testing, and pull a vacuum to ensure system integrity and leak-free operation. Install condensate overflow protection to prevent water damage. Install a digital thermostat compatible with the new HVAC system. Complete system start-up and thoroughly check all operational functions to verify proper performance and efficiency.
