Do I need a licensed HVAC contractor in Washington?

Question 4

How often should I service my HVAC system in Vashon's climate?

Accepted Answer

Seattle has mild, wet winters (37°F lows) and moderate summers rarely exceeding 76°F. Historically a heating-dominated market, but recent heat waves have driven rapid AC adoption.

Many Vashon contractors offer annual maintenance plans that bundle both visits at a discount.
