A contractor quoting a central AC installation in Jones County has to account for what the local weather actually asks of a system before settling on equipment or configuration. 177 severe weather events were recorded in Jones County, Texas between 2015 and 2024. At that rate, severe weather is a standing condition here, not an occasional disruption, and a system sized or installed without accounting for that load will be working against the climate from its first season. Compressors, refrigerant lines, and electrical connections all carry that operating reality, which is why the decisions a contractor makes at install time carry more weight here than they would somewhere this weather seldom materializes.
Ductwork laid down for an older system and an older climate standard is what a contractor has to evaluate before a new central AC unit can be priced or ordered. Half the homes in Jones County, Texas were built in 1969 or earlier (2020-2024 ACS 5-year). That puts the existing duct runs, their dimensions, and their condition at the center of any installation quote here, because a new unit sized for today's efficiency ratings draws air differently than what those runs were built to carry. If the ducts cannot support it, the electrical panel gets checked next. The equipment choice follows from both.
What a Central AC System Includes
The indoor air handler sits inside the home, usually in a utility closet, attic, or basement, and it pulls warm air across the evaporator coil before sending conditioned air back through the vents. The outdoor condenser unit sits on a concrete pad beside the house and holds the compressor, the condenser coil, and the fan that sheds heat to the outside air.
A copper refrigerant line set runs between the two units, carrying refrigerant back and forth to keep the system working as one. The thermostat mounts on an interior wall and is the control point that tells the system when to run and when to stop.
The drawing shows a typical layout, and a licensed contractor determines exactly what applies to this 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.
What Jones County, Texas Requires for HVAC Installation
In Texas a person may not engage in air conditioning and refrigeration contracting unless that person holds a license issued under the state air conditioning and refrigeration contractor law.
Severe Weather History in Jones County
Heat and humidity place real demands on cooling equipment, and so does the weather that moves through this part of Texas. How hard a system has to work over its lifetime is a local question, and the storm record for this area is part of that picture.
