What is the step-by-step AC installation process homeowners should know?

The AC installation process typically runs from an in‑home assessment and upfront quote to system startup and a final homeowner walkthrough. System sizing and any duct needs shape the plan first, then we match equipment and layout to your home. Expect licensed, bonded, insured technicians using top brands like Trane, Mitsubishi, and Daikin, with honest, no‑pressure recommendations and clear, fixed pricing. Same‑day emergency help is available when cooling fails and timing matters. Our teams routinely handle installs in homes across the Seattle area. A tech’s rule of thumb: clean, properly sealed ducts often deliver more comfort per dollar than upsizing equipment. You can also pair your new system with our HAPP Membership for priority service and a 22‑point AC cleaning.

Key steps homeowners can expect:

• Assessment, options, and a fixed‑price proposal.
• Schedule day, equipment prep, and any duct adjustments if needed.
• Install indoor/outdoor units, refrigerant and drain lines, and performance testing.
• Thermostat setup, homeowner walkthrough, and maintenance plan options.
