Central AC repair calls here start from an unusual position. Homes in Aleutians East Borough, AK have essentially no cooling season — no month of the year is warm enough to call for it. A compressor that has sat unused through every month of every year is still a compressor that seals crack in, that contactors corrode, that capacitors drain without load cycling to keep them honest. A contractor diagnosing a failed unit here checks the refrigerant circuit and electrical components for exactly that kind of degradation, not for wear from overwork. The equipment aged on the shelf, not on the job.
Ductwork and panels in houses this old were put in for equipment that has long since been swapped out, so the building itself rarely holds up a repair job. What slows a job down is what the opened system contains: compressor wear, refrigerant hardware that has been patched more than once, parts that may take sourcing because the equipment running in these houses has been running hard for a long time. Half the homes in Aleutians East Borough, Alaska were built in 1981 or earlier (2020-2024 ACS 5-year). That gap between the structure and the equipment sitting inside it is where a repair contractor spends most of their diagnostic time, checking what the unit has accumulated rather than what the house was built to hold.
The Parts of a Central AC a Contractor Checks First
The outdoor condenser unit sits outside the house, usually on a concrete pad at ground level, and houses the compressor and condenser coil. These are the parts a contractor goes to first when the system stops cooling. A failed compressor, a refrigerant leak at the coil, or a seized condenser fan motor are each capable of shutting the whole system down.
Inside the house, the air handler or furnace cabinet holds the evaporator coil and the blower that moves air through your home. The evaporator coil is a common site for refrigerant problems, and a clogged or frozen coil will stop cooling fast. The expansion valve, the capacitors, and the contactor round out the pieces a contractor works through when tracing a fault.
The drawing shows a typical central AC layout, and a licensed contractor determines which components apply and what condition they are in for your specific home.
