The work requires the contractor to perform detailed heat load calculations using the existing ductwork to determine properly sized indoor and outdoor units, ensuring compatibility with the current infrastructure. All new equipment must use EPA-approved A2L refrigerants, preferably R-454B, and involve pulling entirely new line-sets including suction and liquid lines, installing a new liquid line drier indoors near the air handler to mitigate corrosion, and removing and disposing of all existing units with no refrigerant remaining. The contractor must replace all wiring and conduit from existing disconnects to the new equipment, upgrading any corroded components and installing fused disconnects where needed. Thermostat wiring throughout the system must be replaced with UV-rated wire, and the existing thermostat must be upgraded to match the new system’s functionality. All work must be completed within 30 calendar days of award, with performance beginning no later than 10 days after notification to proceed, and must comply with OSHA standards and manufacturer specifications. The system must pass rigorous pressure and vacuum tests, achieve correct CFM airflow through Test and Balance, and be formally accepted at the site by the Contracting Officer’s QAE Representative.

All offerors must maintain an active Unique Entity ID in SAM.gov and comply with federal reporting requirements, including executive compensation disclosures and affirmative action obligations. Security protocols mandate that all personnel provide full personal identification details five days before work starts to obtain site access passes, and all vehicles must be labeled with the contractor’s name and display valid licenses and inspections.
