Step 1 of 3: Equipment

What kind of equipment?*

A two-story house with light beige horizontal siding, a gabled roof, a small covered front porch with dark door, and shrubs along the foundation, set behind a mown lawn and wet sidewalk with large leafy trees on both sides.

A contractor quoting a central AC repair here has to rule out accumulated wear before anything else, even when the unit looks recent. Homes in Yamhill County, OR have essentially no cooling season — no month of the year is warm enough to call for it. With no meaningful cooling season to speak of, the compressor, condenser fan, and contactor sit idle year after year, and long idle periods let small faults go undetected until the first hot afternoon a homeowner finally switches the system on. Refrigerant seals dry out. Contactors corrode. A failed start on a warm day is rarely a workload story in this county.

Ductwork in a house this old was sized and routed for whatever system it held at the time, and the equipment that runs in it now is almost certainly a later addition. Half the homes in Yamhill County, Oregon were built in 1990 or earlier (2020-2024 ACS 5-year). When a refrigerant circuit gets repaired but airflow through the ducts is restricted or leaking at the joints, the fixed component starts working against the house rather than with it. A contractor who opens the unit and finds the part will still need to trace the supply and return runs before the bill reflects what actually needs doing.

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 houses the compressor and condenser coil. Both are common failure points. A compressor that has lost pressure or a coil that has developed a refrigerant leak will stop the system from moving heat out of the house entirely.

Inside, the air handler holds the evaporator coil and the blower. The evaporator coil sits above the furnace or in a dedicated cabinet where the return air passes through it, and a cracked coil or a failed blower motor will show up as warm air, ice buildup, or no airflow at all. The thermostat and the refrigerant lines connecting the two main units round out what a contractor examines.

The drawing shows the general layout of a central AC system, and a licensed contractor determines which components apply and what condition they are in for your particular house.
