Washington Home Services And Local Resources

Washington homeowners should separate contractor registration from professional trade licensing and permit approval. The Labor & Industries verification resources help identify the business and its status; the proposed work still needs the appropriate trade and local checks. For a Seattle heat pump, compare outdoor-unit locations before choosing equipment. Property-line sound, reflecting walls, service clearance and electrical capacity can change the practical design. Ask which mechanical, electrical or other permits apply to the complete installation. Keep the equipment specifications and site sketch with the contract, and require a commissioning explanation so operating settings, condensate handling and future maintenance are understood after the installer leaves.
