A contractor sizing or installing central AC in Lampasas County has to account for what the local climate asks of a system, and that starts with the actual weather record. 46 severe weather events were recorded in Lampasas County, Texas between 2015 and 2024. At that rate, severe weather is real but not relentless, which means a new system here gets sized and sealed for a climate that tests it periodically. The installation quality and the equipment match to the load still matter more than any single storm season, and a contractor quoting the job prices those factors first.
Ductwork laid in for older equipment carries assumptions about airflow and load that a modern central AC system does not share. Half the homes in Lampasas County, Texas were built in 1990 or earlier (2020-2024 ACS 5-year). A contractor quoting an installation here measures and pressure-tests what is already in the walls before the new unit enters the conversation, because ductwork that cannot move the right volume of air at the right pressure will undercut whatever efficiency the equipment is rated for. Electrical service gets the same look: panel capacity and the existing runs have to match what the new system draws. The condition of those two things, not the equipment selection, is what sets the scope and the price.
What a Central AC System Puts in Your Home
The outdoor unit sits on a concrete pad beside the house and holds the compressor and condenser coil, which together shed heat pulled from inside. The indoor air handler mounts in a utility closet, basement, or attic and moves conditioned air through the home. These two units are the core of what a contractor brings in and connects.
A copper refrigerant line set runs between the outdoor unit and the air handler, carrying refrigerant back and forth as the system runs. The thermostat goes on an interior wall and gives the homeowner control over when and how hard the system works.
The drawing shows a general layout of these components, and a licensed contractor determines exactly how they fit the configuration of your 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.
Licensing and Legal Requirements in Lampasas County, Texas
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 Events in Lampasas County
Weather puts a workload on cooling equipment that specs and ratings alone do not capture. How hard a system has to work, and how long it has to hold up, is shaped by what the local climate actually does.
