About this file
This document is an appendix (Attachment 5) containing three detailed historical data tables for Variable Refrigerant Flow (VRF) System Support Services across multiple Joint Base San Antonio (JBSA) facilities from 2020-2025. Table E-1 tracks the total number of work tasks generated for HVAC-related issues per building each year, with Lackland, Fort Sam, and Randolph sites represented. Table E-2 documents the total labor hours charged for these HVAC-related work tasks, showing significant variation across buildings, with Fort Sam Building B16 having the highest total labor hours at 3,936 hours. Table E-3 provides a summarized breakdown of requested services, with "HVAC Service" being the most frequent request (877 total), followed by "Room Too Warm" (267 total) across the tracked years.
The historical data demonstrates the complexity and scope of HVAC maintenance requirements across these military facilities, with fluctuating workload and service needs from year to year. The tables offer granular insights into maintenance demands, showing how different buildings require varying levels of HVAC support, which could be valuable for future resource allocation, staffing, and maintenance planning. The document is marked as Controlled Unclassified Information (CUI) and was last updated on 16 June 2025, suggesting it is part of a current or upcoming service contract procurement process.
