HVAC and plumbing services for the US federal government are procured through SAM.gov for installation, maintenance, and repair at military bases, federal buildings, VA hospitals, and other government facilities. Contract values range from $5,000 for emergency repairs to $50 million for major mechanical system replacements and energy retrofit programs. Federal HVAC and plumbing contracts require compliance with the International Mechanical Code, ASHRAE standards, and Davis-Bacon prevailing wage requirements. Contractors need appropriate state licensing, EPA Section 608 certification for refrigerant handling, and OSHA compliance. Registration in SAM.gov with correct NAICS codes (primarily 238220 and 238220) is essential. The Federal Energy Management Program (FEMP) and Executive Order mandates for energy efficiency are driving significant HVAC modernization across the federal building portfolio. Energy Savings Performance Contracts (ESPCs) administered by DOE provide a unique procurement mechanism where upgrades are funded through guaranteed energy savings. Contractors with experience in geothermal systems, variable refrigerant flow, building automation controls, and commissioning services are in high demand.
