Takes about a minute. No obligation.
A contractor called out to repair a central AC unit in Martinsville has to decide, before quoting anything, whether the failure is storm-related or something the system brought on itself. 73 severe weather events were recorded in Martinsville city, Virginia between 2015 and 2024. At that rate, severe weather is an event here, not a constant condition, and most equipment has not been ground down by repeated exposure to it. A compressor that quit or a coil that is leaking is far more likely to trace back to how old the unit is, how it was installed, or how consistently it was serviced. That is what a contractor checks first.
Ductwork in a house this old has been adapted more than once, and the AC system running in it now is almost certainly not what the house was built around. Half the homes in Martinsville city, Virginia were built in 1958 or earlier (2020-2024 ACS 5-year). When a central AC unit fails in stock like this, what a contractor finds once the system is opened often includes components that manufacturers have discontinued or supply in limited runs. That is not a worst-case scenario; it is what repair work in older housing stock regularly produces. A part that catalogs as available can still carry a lead time long enough to change the scope of the job.
The Parts of a Central AC a Contractor Checks During Repair
The outdoor condenser unit sits outside the house, usually on a concrete pad along an exterior wall, and houses the compressor and condenser coil. These are where a repair call most often leads. A failed compressor, a refrigerant leak at the coil, or a burned-out capacitor in that cabinet will stop the system cold.
Inside the house, the air handler holds the evaporator coil and the blower motor. The evaporator coil can ice over or leak; the blower motor can seize or run weak. The refrigerant lines that connect the two units and the thermostat that signals the whole system are also points a contractor will check before narrowing down the fault.
The drawing shows the general layout of a central AC system, and a licensed contractor determines which components apply to the repair in your particular house.

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.
