Sizing a central AC system in Hudson County starts with what the compressor is actually asked to do each year. Homes in Hudson County, NJ run cooling about three months a year, from June through August. A compressor cycling through a season that compact puts its hardest work into a short window, which means an undersized unit runs at the edge of its capacity rather than cruising through long, easy cycles. The contactor and condenser fan carry that same concentrated load. A contractor who skips a proper load calculation and guesses low on tonnage will produce a system that struggles from its first summer and degrades the compressor faster than one sized to the actual heat gain of the house.
Ductwork already in the house decides more about a central AC installation than the unit a homeowner picks. Half the homes in Hudson County, New Jersey were built in 1966 or earlier (2020-2024 ACS 5-year). That means a large share of the housing stock here was built around heating and cooling configurations that have been reworked, patched, or left in place through multiple equipment cycles since. What a contractor finds in the walls and ceilings, the routing, the sizing, the condition of existing duct runs, is what determines whether a new system goes in cleanly or whether the ductwork has to be partially rebuilt first. The electrical service gets the same look, since what a new unit draws has to match what the panel can deliver.
What Gets Installed With a New Central AC
The outdoor condenser unit sits on a concrete pad beside the house and holds the compressor and condenser coil. Inside, the air handler mounts in a utility space, a basement, or an attic and pushes conditioned air through the home. These two units are what a Central AC installation puts in place.
A refrigerant line set runs between the outdoor and indoor units, carrying refrigerant through insulated copper tubing. The thermostat goes on an interior wall where it reads the air temperature and signals the system to run. An expansion valve, usually housed near the air handler, controls how refrigerant moves between the two sides of the system.
The drawing shows the general layout of a Central AC system, and a licensed contractor determines what applies to your specific house.

What the Installation Actually Looks Like
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
How hard a cooling system has to work is partly a question of local conditions. The weather Hudson County sees puts real demand on installed equipment, which is why the pattern of recorded events here matters when sizing and installing central AC.
