Step 1 of 3: Equipment
A two-story light gray house with white trim, a covered front porch and dark shingled hipped roof, set behind a lawn with a wet concrete walkway leading to the sidewalk, surrounded by leafy trees in late-day sunlight.

A central AC compressor in Bear Lake County sits off almost every day of the year. Homes in Bear Lake County, ID have essentially no cooling season — no month of the year is warm enough to call for it. Seals dry out during long idle stretches, contactors corrode without regular cycling to keep them clean, and refrigerant leaks that opened during a previous run sit undetected until the first warm day a homeowner actually needs the system. A contractor diagnosing a failed unit here checks those idle-period conditions before drawing any conclusion about the compressor itself.

Ductwork laid into a house this old has carried more than one generation of equipment, and what a contractor finds once the system is open reflects that history in specific ways: corroded contacts, worn capacitors, and refrigerant lines that have been touched before. Half the homes in Bear Lake County, Idaho were built in 1974 or earlier (2020-2024 ACS 5-year). For a repair job, that depth of tenure changes the calculus on parts. A contractor pulling a failed component from a system running in stock this old has to establish whether the part is still manufactured, or whether sourcing it means delays and substitutions that shift the repair toward replacement.

The Parts of a Central AC a Contractor Checks First

Isometric line illustration of a cutaway house showing an indoor air handler with branching ducts in the attic space, connected by a line set to an outdoor condenser unit beside the building, with simple furniture in two rooms.

The outdoor condenser unit sits outside the house, usually on a concrete pad beside the foundation, and it holds the compressor and condenser coil. These are the parts a contractor goes to first when a system stops cooling, runs constantly, or makes noise it did not used to make. A failed compressor or a damaged coil is often the reason a system has stopped doing its job.

Inside the house, the air handler or furnace cabinet holds the evaporator coil and the blower. The evaporator coil is a common source of trouble when airflow is weak or ice appears on the unit. The blower motor and the refrigerant lines that run between the two cabinets also fall within what a contractor will inspect and test.

The drawing shows a typical central AC layout, and a licensed contractor determines which parts apply to your specific house and system.
