Takes about a minute. No obligation.
The compressor on a central AC unit in this county does not get much rest. Homes in Imperial County, CA run cooling about seven months a year, from April through October. A contractor coming out on a repair call starts with the compressor, the contactor, and the condenser fan motor, because those are the parts that have been starting and stopping through every one of those months, shedding heat in temperatures that push the system hard. Wear on the contactor shows up as pitting and carbon buildup. A compressor running near the end of its service life often draws high amperage before it fails outright, which a contractor catches on a meter before the unit quits entirely.
Ductwork sized for older, lower-capacity equipment is what many houses here already contain, and when a central AC unit fails, what the opened system reveals is whether the parts it takes are still in production. Half the homes in Imperial County, California were built in 1988 or earlier (2020-2024 ACS 5-year). A contractor working through a repair in stock like this will find refrigerant components, contactors, and control boards that belong to lines manufacturers have since discontinued, and sourcing them adds time and cost that the diagnosis alone never predicts. That is the variable the age of this housing stock puts on the table.
The Parts of a Central AC a Contractor Checks During a Repair
The outdoor condenser unit sits outside the house, usually on a concrete pad at ground level, and it is where heat pulled from inside the home gets released. The indoor air handler or furnace cabinet, tucked in a closet, attic, or utility room, holds the evaporator coil. That coil is one of the first things a contractor looks at when a system stops cooling.
The refrigerant lines run between the two units, and a contractor checks them for leaks or damage when the system is underperforming. The thermostat on the wall and the capacitors and contactors inside the outdoor unit are also common starting points, since both can cause the whole system to stop responding even when the larger components are intact.
The drawing shows the typical layout of these components, and a licensed contractor will assess which ones apply and what condition they are in for your specific home.

What HVAC Repair Looks Like in Imperial County
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.
