A contractor pulling apart a central AC unit in Salem city is not looking at a system battered by relentless weather. 63 severe weather events were recorded in Salem city, Virginia between 2015 and 2024. At that rate, severe weather is a real but occasional variable, and it seldom accounts for what actually fails. Capacitors wear out, refrigerant lines develop leaks, and compressors hit the end of their service life on schedules set by age and how well the system was maintained. The weather record belongs in the picture, but a contractor who leans on it to explain a failed part is skipping past the more likely answer.
Ductwork that predates the current equipment by decades has usually been adapted more than once, and by the time a system fails, the more pressing question is whether the compressor, capacitor, or control board a contractor pulls out can still be sourced. Half the homes in Salem city, Virginia were built in 1971 or earlier (2020-2024 ACS 5-year). A system installed into that stock has had time to move through its full service life, and what a technician opens on a repair call here often turns out to need parts that manufacturers have discontinued. That is what drives the scope and the cost of the job.
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 houses the compressor and condenser coil. These are the parts a contractor reaches first when a system stops cooling. A failed compressor, a refrigerant leak at the coil, or a burned contactor all show up here.
Inside the house, the air handler holds the evaporator coil and the blower fan. The evaporator coil is where a frozen surface or a refrigerant problem becomes visible. The blower moves conditioned air through the supply plenum and into the duct system, so a failing motor affects every room at once.
The drawing shows the typical layout of these components, and a licensed contractor determines which ones apply and what condition they are in for your specific house.

What HVAC Repair Looks Like in Salem
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.
