A contractor quoting central AC in Orange County is not picking from a catalog. 173 severe weather events were recorded in Orange County, Virginia between 2015 and 2024. At that rate, severe weather is a standing feature of the operating environment, and a system sized for average conditions will run harder and longer than it was built to. That gap shows up in the equipment selection, in how the ducts are laid out, and in which components a contractor specifies for longevity rather than price point. Getting the install right here starts with understanding what the system will actually be asked to carry season after season.
Ductwork designed for older equipment does not automatically carry what a new central AC system demands. Half the homes in Orange County, Virginia were built in 1993 or earlier (2020-2024 ACS 5-year). A contractor sizing and placing a new unit here has to run the ductwork before committing to a price, checking whether existing runs can handle the load and whether the sealing is intact enough to make the new system perform. If the ducts fall short, the installation scope changes. The electrical gets checked for the same reason: what a modern central AC unit draws and what the existing service was wired for are not always the same number, and that gap produces real work.
What Gets Installed With a New Central AC
The outdoor condenser unit sits outside the house, usually on a concrete pad beside the foundation, and holds the compressor and the condenser coil. Inside, the air handler mounts in a utility closet, attic, or basement and moves conditioned air through the home. These two units are the core of what a contractor places during a central AC installation.
A copper refrigerant line set runs between the outdoor and indoor units, connecting them through a small penetration in the wall. The thermostat mounts on an interior wall and gives the homeowner control over the system. A condensate drain line runs from the air handler to carry away moisture the coil pulls from the air.
The drawing shows a typical layout, and a licensed contractor determines exactly how each piece fits the conditions of your house.

What HVAC Installation Looks Like in Orange 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 Orange County
Weather puts real hours on heating and cooling equipment. How hard a system has to work, and how long it holds up, is shaped by what the local climate actually does, which is why installation decisions in Orange County are not the same as those anywhere else.
