Before a contractor can size a new system for a house here, they have to look at what is already in the walls and ceiling, not assume it. Half the homes in Washington were built in 1985 or earlier (2020-2024 ACS 5-year). Ducts that were sized for one unit of equipment may be too restrictive or too leaky for a modern replacement. The electrical service has to be measured against what the new equipment actually draws. A quote built on assumptions alone will either come apart during install or produce a system running against conditions it was never specified for.

A condenser sitting outside in Washington faces real punishment: driving rain, hard freezes, high winds, and summer heat that pushes the refrigerant circuit hard. Equipment sized or positioned without accounting for those conditions works against itself from the start. The contractor you are matched with reads the local exposure and specifies what actually fits it.
Washington HVAC Installation and Repair License Requirements
Washington sets its own licensing rules for HVAC installation and repair work, and the provisions here are quoted directly from state sources rather than paraphrased.
Washington requires contractor registration rather than an HVAC licence: every contractor must register with the Department of Labor and Industries, and advertising, bidding or working as a contractor without that registration is a gross misdemeanour.
A state license for this trade determines who is legally permitted to do the work on your home. A contractor operating without the required registration cannot lawfully take on that job. Every contractor this site routes a request to holds the license Washington requires for HVAC installation and repair.
