  • Installation and repair work that counts as construction carries Davis-Bacon prevailing wages; contracts over $150,000 also need Miller Act bonds.
  • Technicians handling refrigerants need EPA Section 608 certification, and the work must be done under the licenses required by the state.
  • Hospital and laboratory jobs often add infection control and phasing requirements that affect your schedule and price.
