Takes about a minute. No obligation.
The compressor in a central AC unit takes its hardest hits at startup, and a system that cycles on and off through a full summer puts that stress on the contactor and capacitor every time. Homes in Hudson County, NJ run cooling about three months a year, from June through August. By the end of a season like that, those switching components have taken far more punishment than the refrigerant lines or the coil, and a contractor diagnosing a fault here opens the electrical compartment before anything else. A compressor that reads as failing often has a capacitor that can no longer hold a charge, and replacing it costs a fraction of what a compressor swap runs.
Ducting in a house this old was put in around a system that is almost certainly gone. When a central AC repair opens the equipment now sitting in that ductwork, what the contractor finds is specific to the replacement history of that unit, and the parts it takes may have a thin supply chain. Half the homes in Hudson County, New Jersey were built in 1966 or earlier (2020-2024 ACS 5-year). That gap between the building and the equipment running in it is where a repair job gets complicated: a compressor or control board from a mid-cycle replacement can be hard to source, and a contractor has to know that before quoting a fix.
The Parts of a Central AC a Contractor Checks First
The outdoor condenser unit sits outside the house, usually on a concrete pad along a side or rear wall, and it carries the compressor and condenser coil. When the system runs but the house stays warm, a contractor looks here first. A failed compressor, a refrigerant leak at the coil, or a seized condenser fan motor will each stop the system from shedding heat.
Inside the house, the air handler holds the evaporator coil and the blower. The evaporator coil is where the system pulls heat out of indoor air, and a frozen coil or a dirty one will cut airflow and cooling both. The blower motor gets checked alongside it, because a weak motor starves the whole system of air regardless of how well the coil is working.
The drawing shows the general layout of a central AC system, and a licensed contractor determines what applies to the specific equipment and configuration in your home.

What HVAC Repair Looks Like in Hudson 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 Hudson County
Extreme weather puts real stress on central AC systems, forcing them to run harder and longer than they were sized for. How often that happens here shapes how quickly components wear and how often repair work comes up.
