Need a HVAC / Ventilation Services Contract in Washington? AroundWire Can Help

In Washington State, contracts for HVAC/Ventilation Services typically require contractors to hold a valid Washington State Department of Labor & Industries (L&I) contractor’s license, with specific endorsements for HVAC or refrigeration work. Technicians must also possess relevant EPA Section 608 certification for refrigerant handling. State and local building codes, including the Washington State Energy Code and mechanical codes, set minimum standards for installation and repair work, and contracts should reference compliance with these codes. Prevailing wage requirements often apply for public projects, per RCW 39.12, and contracts should include wage rate documentation if applicable. Insurance is a standard obligation: contractors are generally required to maintain commercial general liability, workers’ compensation (through L&I), and sometimes professional liability coverage. Indemnification clauses are common to allocate risk, and performance/payment bonds may be mandated for public sector jobs. Payment terms usually follow a net-30 schedule, with retainage of up to 5% held until project completion and acceptance, as per RCW 60.28. Dispute resolution provisions often favor mediation or arbitration before litigation, in line with Washington’s preference for alternative dispute resolution. Contracts should clearly address scope of work, change order procedures, warranty provisions (usually one year minimum), and compliance with environmental regulations on refrigerant use and disposal. Local jurisdictions may impose additional permitting or inspection requirements, so contracts should allocate responsibility for securing permits and passing inspections.
