Maca - cyclic HVAC upgrades

The Department of the Interior National Park Service Southeast Region issued a pre-solicitation notice for HVAC upgrades at Mammoth Cave National Park under solicitation number 140P5325R0019. The project involves replacing 18 aging HVAC units with modern, energy-efficient models to improve climate control, enhance indoor air quality, reduce operational expenses, and ensure compliance with safety, environmental, and accessibility regulations. The work falls under NAICS Code 238220 for Plumbing, Heating, and Air-Conditioning Contractors. Contractors must maintain an active SAM registration and Unique Entity number to be eligible for consideration. However, this pre-solicitation notice has been cancelled by amendment, and the solicitation will not be posted as originally planned for May 28, 2025, with the June 27, 2025 response deadline.

This opportunity was designated as a total small business set-aside with a size standard of $19 million for qualifying contractors. The original timeline called for project completion by September 1, 2025, indicating an aggressive implementation schedule for the HVAC replacement work. The project specifically targets the replacement of 18 HVAC units throughout the Mammoth Cave National Park facilities. No incumbent contractors or current service providers were identified in the available documentation. The cancellation of this pre-solicitation means that interested small businesses in the HVAC contracting sector will need to monitor for potential reissuance of this requirement or similar opportunities from the National Park Service.
