Sizing a central AC system for a Panola County home is not a calculation a contractor can afford to get roughly right. Homes in Panola County, MS run cooling about five months a year, from May through September. A compressor cycling through that stretch accumulates wear on its contactor and condenser fan at a pace that punishes a marginal install long before the unit reaches a natural end of life. Contractors working a quote here have to run a full load calculation against the house envelope, because a unit that struggles to hold temperature through August will not hide that fault.
Ductwork sized and routed for older systems does not automatically carry what a new central AC unit demands. A contractor installing in this county has to assess whether the existing ducts move enough air, and whether the electrical service can handle the draw, before the new equipment is even priced. Half the homes in Panola County, Mississippi were built in 1988 or earlier (2020-2024 ACS 5-year). That gap between what the house was built with and what runs in it now is where installation jobs here get complicated or stay simple.
What Gets Installed With a New Central AC
The outdoor condenser unit sits on a concrete pad outside the house and holds the compressor and condenser coil, which are the heart of the system. Inside, the air handler or furnace cabinet stands in a utility closet, basement, or attic and houses the evaporator coil and blower that move conditioned air through the home.
The thermostat mounts on an interior wall where it reads the air temperature and tells the system when to run. Refrigerant lines connect the indoor and outdoor units by running through a small penetration in the wall, and a condensate drain line carries moisture pulled from the air to a floor drain or outside.
The drawing shows a typical layout, and a licensed contractor determines exactly how each piece is positioned and routed for your specific house.

What the Installation Actually Looks Like
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.

Mississippi licenses residential HVAC work at every tier and at any price: a subcontractor of any tier doing heating, ventilation or air conditioning work on a residential construction or improvement project must be licensed by the State Board of Contractors no matter the dollar amount.
Severe Weather Events in Panola County
Weather in this part of Mississippi puts real stress on cooling equipment, running it harder and longer than specs written for moderate climates assume. A central AC system sized and installed for local conditions handles that load differently than one put in without it in mind.
