Step 1 of 3: Equipment

What kind of equipment?*

A two-story house with light gray horizontal siding and a covered front porch, seen from across a wet street with a lawn, sidewalk, shrubs and leafy trees in low sunlight.

Central AC in Lewis County sits idle. Homes in Lewis County, WA have essentially no cooling season — no month of the year is warm enough to call for it. A compressor that has never been pushed through a real cooling season carries its stress elsewhere: in the seals and contacts that degrade from disuse, and in the first hard start after a long standstill. When a contractor opens a unit here, age and quality of the original install tell more about the failure than anything the local climate demanded of it.

Ductwork in a house that has housed several generations of cooling equipment tells a contractor more about how a repair will go than the failed component does. Half the homes in Lewis County, Washington were built in 1980 or earlier (2020-2024 ACS 5-year). A system that breaks down in stock like this sits at the end of a long chain of prior decisions, and what a contractor finds in the ducts once the panels come off shapes both the scope and the parts list. Seals degrade, runs get re-routed around renovations, and return paths get compromised over time. The repair on the unit is often straightforward. The ductwork condition is where the job either stays simple or does not.

The Parts of a Central AC a Contractor Checks First

The outdoor condenser unit sits outside the house, usually on a concrete pad beside the foundation, and it carries the compressor and the condenser coil. Both are common starting points when a system stops cooling. The air handler or furnace cabinet inside the house holds the evaporator coil and the blower, and a refrigerant leak or a failed blower motor will show up here.

The refrigerant lines run between the indoor and outdoor units, and a contractor checks them for leaks or damage where they pass through walls or sit exposed. The thermostat, mounted on an interior wall, controls the whole system, and a faulty reading or a wiring fault there can mimic a much larger problem.

The drawing shows a typical layout, and a licensed contractor determines which components apply and what condition they are in for your specific house.
