Sizing a central AC correctly for this house matters more than the equipment brand. Homes in Tulare County, CA run cooling about two months a year, from July through August. A compressor that cycles through a short, concentrated season and then sits idle carries its wear in bursts, and a unit that was undersized or poorly charged at installation does not get the gradual feedback of a long run to surface the problem early. The contractor has to get the load calculation right the first time, because the next chance to catch an install error arrives when the heat is already on and the phone lines are full.
Ductwork sized and sealed for an older system does not automatically carry a new one at rated efficiency. Half the homes in Tulare County, California were built in 1983 or earlier (2020-2024 ACS 5-year). A contractor quoting a central AC installation has to open the supply and return runs, check the existing path against what the new unit actually moves, and find out whether the electrical service can handle the draw. If the ducts are undersized or the panel is already at its limit, those get addressed before the equipment question is settled.
What Gets Installed With a New Central AC
The outdoor condenser unit sits outside the house, usually on a concrete pad at the side or rear, and it holds the compressor and the condenser coil. Inside, the air handler mounts in a closet, attic, or utility space and pushes conditioned air through the home. Together these two units form the heart of the system.
The refrigerant line set runs between the outdoor and indoor units, carrying refrigerant through copper tubing that gets routed along the exterior or through the structure. The thermostat mounts on an interior wall and gives the homeowner control over when the system runs and at what temperature.
The drawing shows how these pieces fit together in a typical installation, and a licensed contractor determines exactly how each one applies to your house.

What HVAC Installation Looks Like in Tulare 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.

Weather Stress on HVAC Systems in Tulare County
Extreme weather events put real demand on heating and cooling equipment, shortening service life and pushing systems harder than rated conditions assume. How often that happens here shapes what a contractor specifies and how a new central AC installation is sized for Tulare County.
