Sizing a central AC system for Burlington County starts with understanding what the compressor is actually asked to do. Homes in Burlington County, NJ run cooling about three months a year, from June through August. A compressor cycling through a tight, reliable summer season accumulates wear on its contactor and condenser fan in a predictable pattern, and a system that is undersized runs longer on the hottest days, pushing those components harder than the load calculation assumed. A contractor quoting an installation here sets the capacity around that concentrated demand, because an undersized unit does not recover quietly when the heat peaks.
Older ductwork, not the new equipment, is what sets the scope of a central AC installation in much of Burlington County. Half the homes in Burlington County, New Jersey were built in 1977 or earlier (2020-2024 ACS 5-year). That stock was built around systems with different load characteristics than what runs in houses now, which means the duct runs a contractor finds behind the walls were sized for something other than a modern central AC unit. Whether those runs can carry the new system's airflow without modification is what a contractor has to work out before anything else on the job gets priced.
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, the hardware that does the heaviest work in the system. Inside, the air handler or furnace-mounted coil lives in a utility space, basement, or closet, where it connects to the duct system and conditions the air before it moves through the house.
A refrigerant line set runs between the two units, linking the outdoor and indoor sides into one closed loop. The thermostat goes on an interior wall where it reads the house temperature and tells the system when to run.
The drawing shows a typical layout, and a licensed contractor determines exactly what fits and where in your home.

What happens on installation day
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.
What Burlington County and New Jersey Require for HVAC Installation
In New Jersey the HVACR licence is the State's alone: a municipality, local board of health or any other agency may not issue or renew a Master HVACR contractor's licence.
New Jersey requires a Master HVACR contractor licence: no person or business may engage in the business of HVACR contracting, or advertise as a Master HVACR contractor, without being authorised under the State HVACR Contracting License Law.
Severe Weather Events in Burlington County
Weather puts a measurable load on cooling equipment, and that load is shaped by what a specific area actually sees. Sizing and installing central AC for a Burlington County home means accounting for local conditions, not regional averages.
