Seattle heating and cooling plans should account for the wetter cool season and warmer summer conditions. NOAA's Seattle–Tacoma airport climate normals show the seasonal pattern. Before fall, test heat and keep leaves and vegetation clear of outdoor equipment. Before summer, check cooling operation and follow the manufacturer's filter guidance. Seattle City Light's heating and cooling resource explains heat-pump options, including ducted and ductless systems. If you are considering either type, ask the installer to evaluate the home's heating load, existing ducts, electrical work, and controls.
Use the Seattle Department of Construction and Inspections mechanical permit guidance to confirm the approval and inspection process for the proposed work. Washington requires construction contractors, including HVAC/R specialty contractors, to register with L&I and maintain the required bond and liability insurance. Verify that the contractor registration is active and review any separate electrical or plumbing credentials needed for the proposed scope. Review L&I's registration requirements and check the business through its Verify tool.
City Light lists qualifying air-source heat-pump discounts through participating contractors and distributors. Its page also explains oil-to-heat-pump conversion rebates and assistance for income-eligible households. Check the current program, equipment requirements, and contractor participation before purchasing; these offers are not automatic for every installation. Put responsibility for any program paperwork, permits, and final equipment testing in the written installation scope.
