Takes about a minute. No obligation.
A compressor that starts cold after a long off-period is where most repair calls in this area begin. Contactors corrode, capacitors lose charge, and refrigerant connections that were marginal last season announce themselves the first time the unit is asked to run hard. Homes in Owyhee County, ID run cooling about two months a year, from July through August. Contractors working a repair here look at those startup components first, because the compressor has not been cycling through the spring to surface a slow failure early.
Central AC repair in housing this old frequently stalls not at the diagnosis but at parts availability. Half the homes in Owyhee County, Idaho were built in 1984 or earlier (2020-2024 ACS 5-year). Equipment installed decades after a house was framed draws on a supply chain that has no obligation to outlast it, and when a compressor or control board reaches end of production, a contractor sourcing it learns that quickly. A system that looks repairable on the outside can turn out to need a component that is simply no longer made.
The Parts of a Central AC a Contractor Checks First
The outdoor condenser unit sits outside the house, usually on a concrete pad against an exterior wall, and it carries the compressor and the condenser coil. Both are common trouble spots. A failed compressor means the system runs but moves no heat; a fouled or damaged condenser coil means the unit runs hard and still falls short.
Inside the house, the air handler holds the evaporator coil and the blower. The evaporator coil is where the system pulls heat out of indoor air, and a frozen or leaking coil shows up fast as warm air or water on the floor. The blower pushes conditioned air into the duct system, and a failing motor makes itself known through weak airflow or noise. A metering device and refrigerant lines connect the two units, and low refrigerant is one of the first things a contractor rules out.
The drawing shows the general layout of a central AC system, and a licensed contractor determines which components apply to your specific house and situation.

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.
