Takes about a minute. No obligation.
A central AC compressor in this area works hard through summer and then sits idle through a long fall, winter, and spring. Homes in Essex County, NJ run cooling about three months a year, from June through August. That extended off period is where failures incubate: the capacitor loses charge-holding capacity, the contactor pits and corrodes, and the compressor itself struggles on the first hot start after months of disuse. A contractor diagnosing a breakdown here checks those standby-sensitive components first, because the short cooling season means fewer hours of sustained wear and more cycles of cold restart stress.
Ductwork in a house passes through many equipment cycles over its life, and each swap leaves the system a little further from what that ductwork was originally sized for. Half the homes in Essex County, New Jersey were built in 1958 or earlier (2020-2024 ACS 5-year). When a contractor opens a central AC unit here and finds a failed component, the search for a replacement part runs against the full depth of that history. A part that fits an older system is not always still in production, and a contractor who confirms that early changes the repair conversation from a simple swap to a decision about scope.
The Parts of a Central AC a Contractor Checks First
The outdoor condenser unit sits outside the house, usually on a concrete pad along the foundation, and it is where heat gets shed to the outside air. The indoor air handler or furnace coil sits inside, most often in a basement, closet, or attic, and it is where the refrigerant does its work on the indoor air. Both are common starting points when a system is underperforming or not cooling at all.
The refrigerant lines run between the two units, and a contractor checks them for leaks or damage when pressures are off. The thermostat on the wall controls the whole system, and a fault there can mimic a much larger problem. The capacitors and contactors inside the condenser are small electrical components that fail often enough that contractors go to them early.
The drawing shows a typical central AC layout, and a licensed contractor will determine which components apply to your specific home and what each one needs.

What HVAC Repair Looks Like in Essex 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.
