About this file
This document is a Questions and Answers file for a Department of the Army HVAC repair solicitation (W912JM25QA014) at Fort Stewart, Georgia. The contract requires replacing 39 HVAC compressors across 37 buildings at the Land Dominance Center, with specific requirements including new compressors, refrigerant (primarily R410A or R421A for R-22 systems), filter dryers, sight glasses, and unit capacitors. Key details from the Q&A include confirmation of work scope, clarification on refrigerant types, work hours (0730-1600), and immediate project start upon award.
The solicitation involves comprehensive HVAC system repairs with technical specifications around refrigerant replacement, installation protocols, and site access. Contractors will need to handle compressor replacements across various building types, with mounting locations varying and no specialized equipment beyond a ladder required. Post-installation responsibilities include diagnosing potential additional issues and providing repair cost estimates if the compressor replacement does not fully resolve system functionality. A location map will be provided after award, and no additional pre-award information will be shared.

1. In the event of a leak in the coil on the outdoor or indoor unit after the installation of compressors, what is the protocol? Are we held responsible for ensuring the unit is operable if the issue extends beyond the compressor repair? Additionally, will we be billed for repairs made on-site if the compressor replacement does not resolve the issue?
If the repair does not put the unit in service, the contractor will determine what other issues exist and provide the Government with a cost estimate to complete the repairs.
2. Should we assume that all units in each building are of the same size and brand? The number of buildings/units listed does not add up to the specified 39 compressors. Given the significant price difference between a 5-ton and a 2-ton compressor, could you provide clarification on this discrepancy?
3.
The number does add up. Please ensure you review the number of compressors by building. No additional information will be provided prior to award.
4. Are there any specific work hour limitations for the execution of this project?
Normal business hours are 0730-1600, but we are flexible.
5. What is the mounting location of the existing HVAC units, and what is the height of the buildings they serve?
Varies, no equipment beyond a ladder is required to service equipment.
6. Will the HVAC systems be recharged with the existing refrigerants R-22 and 410-A, or is there a plan to switch to the newer standard 454 refrigerant?
R410A should be used for 410A Systems. An alternate is provided for the R22 Systems due to the elevated refrigerant cost (for R22) and it’s availability.
7. Could use 407-C for the system refrigerant instead of the R-22, due to the limited availability of R-22. Would that work?
In Para 9, Standard of Workmanship, of the scope of work it states, “R-22 systems shall be charged utilizing R421A Refrigerant.”
8. Do you happen to know what type of HVAC system is on the base?
See Summary of failed compressors in section 5 of the PWS. All Manufacturers, system types, refrigerants and model numbers are provided.
9. How soon would we need to start after being awarded?
Immediately.
10. Exact Locations of the Compressors: Could you please confirm whether a detailed site plan or list of the specific building locations for the 39 units is available?
Location map will be provided after award.
11. Are there any blueprints of the location?
No. See paragraph 17 in section 5.
12. Do we need to replace the insulation on the suction line?
The insulation on the suction line will be replaced if needed from the outside unit to the exterior wall. See updated PWS on SAM.GOV.
