A contractor quoting a central AC installation in Lowndes County starts by looking at the house, not the weather. 28 severe weather events were recorded in Lowndes County, Alabama between 2015 and 2024. At that rate, severe weather is an event here, not a standing condition, which means a system's real working life is shaped by how well it was sized and installed in the first place. Undersized equipment runs longer cycles. Poorly sealed ductwork loses more of what the unit produces. Those are the variables a contractor has to get right, and in a county where weather load is light, they are the whole story.
Ductwork laid down for earlier equipment carries different geometry, sealing standards, and load assumptions than a modern central AC system demands. Half the homes in Lowndes County, Alabama were built in 1991 or earlier (2020-2024 ACS 5-year). That gap between when a house was framed and what a contractor now sets into it is where installation jobs either go straight or get complicated. A contractor sizing and placing a new system here has to assess what the existing duct network will actually handle before the unit itself enters the conversation.
What Gets Installed With a New Central AC
The outdoor condenser unit sits outside the house, usually on a concrete pad along a side or rear wall, and houses the compressor and condenser coil. Inside, the air handler or furnace with its evaporator coil mounts in a utility closet, basement, or attic and is the piece that conditions the air before it moves through the home.
A refrigerant line set runs between the two units, connecting the indoor and outdoor sides of the system. The thermostat goes on an interior wall and is the control point the homeowner sees and uses every day. A condensate drain line also runs from the air handler 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 house.

What HVAC Installation Looks Like in Lowndes 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.
