Takes about a minute. No obligation.
A compressor that starts cold after months of sitting is where most repair calls in this county begin. Homes in Passaic County, NJ run cooling about two months a year, from July through August. Contactors corrode, capacitors drift, and refrigerant-side seals that sat dry all spring show their condition on the first hot day. The contractor's first job is to work out whether the failure came from the run or from the idle, because that changes which parts get replaced and what the bill looks like.
Half the homes in Passaic County, New Jersey were built in 1956 or earlier (2020-2024 ACS 5-year). That means the central AC equipment a contractor opens today has been cycling through ductwork and electrical infrastructure that was put in for something else entirely, adapted more than once, and never replaced wholesale. When a refrigerant call turns out to be a failed contactor, or a contactor call turns out to be a coil packed with decades of debris, the housing is why the diagnosis moved. Parts availability is its own question: what a system this old actually takes, as opposed to what cross-referenced substitutes are stocked locally, shapes the repair bill more than the labor does.
The Parts of a Central AC a Contractor Checks First
The outdoor condenser unit sits outside the house, usually on a concrete pad against an exterior wall, and it is where heat gets shed to the outside air. The indoor air handler or furnace sits inside, most often in a basement, closet, or attic, and it is where the blower and the evaporator coil do their work. These two units are the pieces a contractor goes to first when the system is not cooling.
The evaporator coil lives inside the air handler and is a frequent source of trouble when airflow drops or ice forms on the equipment. The refrigerant lines run between the two units, and the expansion valve and the capacitors that start the motors are the smaller components a contractor checks when one unit runs but the other does not.
The drawing shows a typical central AC layout, and a licensed contractor will assess what applies to the specific equipment and setup in your home.

What Happens When the Contractor Arrives
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.
