A contractor quoting central AC installation in Paulding County has to size the system around what this area actually puts equipment through, not around what a catalog default assumes. 143 severe weather events were recorded in Paulding County, Georgia between 2015 and 2024. At that rate, severe weather is a routine condition of operating here, and a system that is undersized or poorly sealed against heat loading will lose ground fast when the weather pushes hardest. A contractor who treats that record as background noise will quote a system that fits the average day and fails the hard ones.
Existing ductwork in a house from this era was laid out for equipment with different airflow demands than what a new central AC system moves. Half the homes in Paulding County, Georgia were built in 2002 or earlier (2020-2024 ACS 5-year). A contractor installing a new system has to confirm that the trunk lines, branch runs, and return paths will actually carry what the new unit requires, and that the electrical service will support the load. Where the ductwork falls short, the installation scope grows before the new equipment is ever set in place.
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 or furnace-based evaporator coil assembly mounts in a utility closet, basement, or attic and is the point where cooled air enters the duct system. These two units are the core of what a contractor puts in.
A copper refrigerant line set runs between the outdoor and indoor units, connecting them through an exterior wall. The thermostat mounts on an interior wall and gives the homeowner control over when the system runs and at what setpoint. A condensate drain line also runs from the indoor unit to carry moisture out of the house.
The drawing shows a typical layout, and a licensed contractor determines exactly how each piece fits the conditions of your home.

What HVAC Installation Looks Like in Paulding 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 Paulding County
Georgia's climate puts real demands on cooling equipment, and those demands are not uniform across the state. What happens in Paulding County shapes how hard a system has to work and how long it holds up, which is why local weather history belongs on a page about central AC installation.
