Carrier Package Unit Air Conditioning Systems- AMC

Background & Existing System Condition

                             The school operates 13 Carrier Package Unit Air-Conditioning systems of varying capacities (5 TR to 25 TR). All units are out of manufacturer warranty, aged, and operating under stressed conditions.

                              Units operating without OEM warranty coverage. - Mixed operational status: some units dismantled, some heavily loaded. - High sensitivity of cooling availability due to classroom, auditorium, and administrative occupancy.

                              The intent of this RFQ is to appoint a competent, responsive, and SLA-driven HVAC service provider capable of maintaining aging Carrier package units with school-operation-focused service levels.
