AC Replacement & Installation in Washington: what's different
AC Replacement & Installation across Washington depends on the climate (IECC climate zones 4–6). Marine climates have mild summers, so many homes added cooling only recently, often with heat pumps or mini-splits. Heat waves bring sudden demand for AC service and installs.
In Washington specifically: heat waves. Homes without AC are vulnerable during extreme heat; heat pumps add cooling. Wildfire smoke: Summer smoke makes filtration upgrades valuable.
Washington contractors register with the Department of Labor & Industries, and HVAC electrical work requires a specialty electrician certification. Ask any contractor for their license number before work starts, and expect a written price for AC Replacement & Installation.
Puget Sound Energy, Seattle City Light, Avista and many public utility districts supply electricity. PSE, Avista and Cascade Natural Gas supply gas.

Is a ductless heat pump worth it with baseboard heat?+
Usually yes. It's far more efficient than electric resistance heat and adds summer cooling.
What size AC do I need?+

In most places, yes. Equipment replacement usually requires a mechanical permit from your city or county, and the contractor normally pulls it.
