Need a HVAC Contract in Washington? AroundWire Can Help

In Washington State, HVAC service contracts—covering installation, maintenance, or repair—are subject to a combination of state and local requirements. Contractors must hold an active Washington State contractor’s license, and HVAC technicians are generally required to possess valid certifications (e.g., EPA Section 608 for refrigerant handling). Prevailing wage laws apply to public contracts, and contractors must register with the Department of Labor & Industries (L&I). Contracts typically specify detailed scopes of work, compliance with Washington State Energy Code, and adherence to local building and safety codes. Insurance requirements are stringent: contractors are generally required to carry commercial general liability insurance (often $1M per occurrence), workers’ compensation, and, where applicable, additional insured endorsements for project owners. Performance and payment bonds are common, especially on public works projects. Risk factors addressed in contracts include hazardous materials (like asbestos), environmental regulations, and site access. Payment terms usually follow a net-30 or milestone-based schedule, with retainage (up to 5%) held until project completion and acceptance, as permitted under RCW 60.28. Dispute resolution often favors mediation or arbitration prior to litigation, in line with local contracting norms. Washington State’s public procurement statutes and local municipal codes may introduce further requirements, such as mandatory use of certified minority- or women-owned businesses on certain contracts.
