EPA Section 608 certification is mandatory for refrigerant handling. NATE (North American Technician Excellence) certification is increasingly preferred. State mechanical/HVAC contractor licenses are required in most jurisdictions. For federal work, bonding (per the Miller Act for contracts over $150,000) and appropriate insurance are required. Security clearances may be needed for DOD installations.

ESPCs allow federal agencies to procure energy-saving improvements (including HVAC modernization) with no upfront capital cost. An energy service company (ESCO) designs, installs, and finances improvements, then guarantees energy savings that pay for the project over the contract term (up to 25 years). DOE manages the federal ESPC program with pre-qualified ESCOs.

The Davis-Bacon Act requires prevailing wages on federally funded construction contracts over $2,000. HVAC installation falls under construction wage classifications. Wage rates vary by county and trade classification — check the Department of Labor's Wage Determinations at sam.gov before bidding. State prevailing wage laws may also apply to state-funded projects.

The Miller Act requires performance and payment bonds on federal construction contracts over $150,000. HVAC installation projects typically trigger Miller Act requirements. Many state and local governments have similar bonding requirements (Little Miller Acts). Bonding capacity is a key factor in winning larger HVAC contracts — build bonding relationships early.
