Takes about a minute. No obligation.
A contractor quoting central AC installation in Kitsap County has to settle one question before sizing equipment: how a compressor behaves when it almost never runs. Homes in Kitsap County, WA have essentially no cooling season — no month of the year is warm enough to call for it. Capacitors degrade on idle equipment, refrigerant seals dry, and contactors corrode without the cycling that would otherwise keep them working. A system that starts for the first warm stretch in years is doing so with components that have sat, not ones that have worn gradually into failure. That shifts what a careful installer specifies, because a unit sized purely for peak load says nothing about how it will hold up through long stretches of dormancy.
Ductwork laid out for a furnace and nothing else shapes what a central AC installation actually costs and how long it takes. Half the homes in Kitsap County, Washington were built in 1986 or earlier (2020-2024 ACS 5-year). That puts a large share of the county's homes in a category where what is already in the walls and ceiling is the first thing a contractor has to evaluate, not the equipment being swapped in. Duct runs sized and routed for heating alone can restrict airflow a cooling system depends on, and that is what drives decisions about modification or replacement before any unit gets ordered.
What Gets Installed With a New Central AC
The outdoor unit sits on a concrete pad beside the house and holds the compressor and condenser coil. Inside, the air handler or furnace-mounted evaporator coil lives in a utility space, basement, or closet. These two units are the core of what a contractor places and connects during a central AC installation.
A refrigerant line set runs between the indoor and outdoor units, carrying the refrigerant that links the two sides of the system. The thermostat goes on an interior wall and gives the homeowner control over the whole system. Drain lines route condensation away from the indoor unit to keep moisture from building up.
The drawing shows the general layout of a central AC system, and a licensed contractor determines exactly how each piece fits the specific conditions of your home.

What the installation looks like from your side
Split-system central air conditioners rated below 45,000 Btu/h manufactured on or after January 1, 2023 must meet a federal minimum of 13.4 SEER2.
Split-system central air conditioners rated at or above 45,000 Btu/h manufactured on or after January 1, 2023 must meet a federal minimum of 13.4 SEER2.
Split-system central air conditioners manufactured between January 1, 2015 and December 31, 2022 had to meet 13 SEER, the metric that preceded SEER2.
Single-package central air conditioners manufactured on or after January 1, 2023 must meet a federal minimum of 13.4 SEER2.
Space-constrained central air conditioners manufactured on or after January 1, 2023 must meet a federal minimum of 11.7 SEER2.
Federal efficiency standards for split-system central air conditioners and heat pumps are set on each certified combination of outdoor unit and indoor coil rather than on the outdoor unit alone.
Residential and light commercial air conditioning and heat pump systems assembled in the field, including mini-splits and unitary systems, may not be installed on or after January 1, 2025 using a refrigerant with a global warming potential above 700.
A field-assembled system whose specified components were all manufactured or imported before January 1, 2025 carries no installation compliance date under the refrigerant restrictions and may still be installed.
What Kitsap County and Washington Require for HVAC Installation
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.
