Takes about a minute. No obligation.
The compressor in a central AC unit carries the full load of every cooling cycle: starting, running, and shutting down repeatedly across the summer. Homes in Cumberland County, NJ run cooling about three months a year, from June through August. Ninety days of runtime is not nothing, but it leaves the compressor standing idle for the rest of the year, and long idle periods invite their own problems. Refrigerant seals dry out. Contactors corrode between seasons. When a contractor opens a system that has stopped working on the first hot day of June, the failure often traces back to deterioration during the off-season, not to anything the summer asked of it.
Ductwork in a house this old was put in for whatever system ran first, and what a contractor finds inside the cabinet tells them quickly whether a failed part is still in production. Half the homes in Cumberland County, New Jersey were built in 1969 or earlier (2020-2024 ACS 5-year). That gap between when the house was built and when its current equipment was installed means a contractor opening a compressor or a blower motor here is working out whether a replacement part exists at all, not just what it costs. If the part is discontinued, the repair becomes a replacement conversation, and the age of the house has nothing to do with which direction that goes.
The Parts of a Central AC a Contractor Checks During Repair
The outdoor condenser unit sits outside the house, usually on a concrete pad beside the foundation, and it carries the compressor and the condenser coil. These are the pieces a contractor reaches first, because a failed compressor or a fouled coil is often what stops the system cold. The air handler or furnace cabinet inside the house holds the evaporator coil and the blower, and a fault in either one shows up as warm air, weak airflow, or ice forming on the coil.
The refrigerant lines run between the two units, and a contractor checks them for leaks or damage whenever the system is underperforming. The expansion valve and the drain line sit at the air handler end and are common sources of trouble when the indoor coil is freezing or water is pooling near the cabinet. The thermostat, mounted on a wall inside the home, is also on the checklist, since a wiring fault or a failed sensor there can mimic a much larger mechanical problem.
The drawing shows the general layout of a central AC system, and a licensed contractor determines which components apply to your specific installation.

What HVAC Repair Looks Like in Cumberland 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.

Severe Weather Events in Cumberland County
Weather puts load on central AC equipment. Hard conditions accelerate wear on compressors, coils, and electrical components, and what that means for repair frequency is a local question that varies county to county.
