About this file
This is a Questions and Answers document for solicitation 1240LN26Q0005 dated September 23, 2026, addressing clarifications regarding an air handler and rooftop A/C unit replacement project.
The document clarifies the scope of work for replacing HVAC equipment serving rooms 48B and 51. The government's intent is to replace both the rooftop A/C units and indoor DX coils while retaining the existing AH-5 and AH-6 indoor air handlers. New coils must be retrofitted into the existing air handlers with appropriate mechanical items and modifications as needed. The government will accept reuse of existing coils if determined compatible with the new refrigerant and equipment, with modifications such as replacement or retrofit of metering devices. The electrical panel serving the outdoor units is located in the mechanical room; pictures of the panel designation, location, breaker size, voltage, and phase were uploaded to support the site visit findings. The Daikin air handler specifications included in the preliminary submittal were research options considered for direct retrofit but should not necessarily be incorporated into the proposal unless specified otherwise by the government.

AH 5_6 Questions and Answers - 1240LN26Q0005
9/23/2026
1. During the site visit, the onsite mechanics were unable to identify the electrical panels serving the existing AH-5 and AH-6 outdoor units. Could the government provide or confirm the serving electrical panel designation and location, breaker size and voltage and phase. A: Pictures uploaded
2. The SOW states that the contractor shall install new compatible rooftop A/C units and “coils for existing air handlers in room 48B and 51,” which appears to indicate that the existing AH-5 and AH-6 air handlers will remain in place and only the indoor DX coils will be replaced. However, the preliminary submittal provided with the solicitation includes Daikin/Oxygen 8 air-handler equipment information. Please confirm whether the Government's intent is to retain the existing AH-6 and AH-6 and replace only the indoor coils. A: The intent is to replace both roof top and coils but keep indoor air handlers. Coils will need to be retrofitted into existing Air Handler. I
3. If the existing air handlers are to remain, please confirm whether the existing coils must be completely replaced as currently indicated in the SOW, or whether the Government would consider reuse of the existing coils with appropriate modifications, such as replacement/retrofit of the metering devices, if the coils are determined to be compatible with the new refrigerant and equipment. A: The existing air handlers should remain, with the new coils and appropriate mechanical items retro fitted into them.
4. Exact location of the electrical panel feeding the outdoor units
A: Mechanical room
5. Should the Daikin air handler specifications be incorporated into the proposal?
A: The Daiken was an option during our Market research for direct retrofit.
