A contractor quoting a central AC install in Maury County has to think beyond the square footage of the house. 135 severe weather events were recorded in Maury County, Tennessee between 2015 and 2024. At that rate, severe weather is a standing condition in this area, and a system sized or installed to minimum spec will be carrying a load the spec did not fully account for. Ductwork sealing, equipment placement, and load calculations all shift when the climate has this kind of record behind it. A contractor who treats those as optional line items leaves the homeowner with a system that was underprepared from day one.
Ductwork laid down for an earlier era of equipment carries assumptions about static pressure, return air, and load distribution that do not always match a modern central AC system. Half the homes in Maury County, Tennessee were built in 1994 or earlier (2020-2024 ACS 5-year). A contractor installing a new unit in housing typical of this county has to assess whether the existing duct layout will actually deliver what the new system is rated for, or whether sections of it need to be reworked before the equipment ever runs. The electrical service gets the same look. What a homeowner pays for and what they get out of a new system depends heavily on what those assessments turn up.
What a Central AC Installation Covers, Piece by Piece
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-mounted evaporator coil lives in a utility closet, attic, or basement and is where cooled air enters the home's circulation. These are the two main pieces a contractor brings in and sets in place.
The refrigerant line set runs between the outdoor and indoor units, connecting the two halves of the system through a wall or floor penetration. The thermostat goes on an interior wall and gives the homeowner control over when and how the system runs. A condensate drain line also runs from the indoor coil to carry away moisture the system pulls from the air.
The drawing beside this text shows a typical layout, and a licensed contractor determines exactly how these pieces fit the construction of your house.

What the installation looks like from your side
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 Maury County
Extreme weather puts real demand on cooling equipment, and what happens in this area shapes how hard a central AC system has to work over its life. Sizing and installing that equipment well is a local decision, not a general one.
