A contractor sizing and quoting a central AC install in Piute County has to reckon with an unusual fact about the equipment's life here. Homes in Piute County, UT have essentially no cooling season — no month of the year is warm enough to call for it. A compressor that never runs still degrades: refrigerant migrates, seals dry, and the contactor sits in one position long enough to corrode. The install decisions that matter most here are about protecting components during idle storage, not about sizing for peak summer load. Refrigerant line routing, unit placement, and electrical protection all carry more weight than they would somewhere the system cycles hard each summer.
Ductwork laid down for an earlier generation of equipment was designed around how that equipment moved air, and a new central AC system does not inherit that design for free. Half the homes in Piute County, Utah were built in 1976 or earlier (2020-2024 ACS 5-year). A contractor installing central AC in this county has to establish whether the existing duct layout will carry the load a new system pushes through it, and that is a physical inspection, not an assumption drawn from a permit date. Where the ducts fall short, the electrical service is the next question. Both have to be settled before the unit itself becomes relevant.
What a Central AC Installation Puts in Your Home
The outdoor condenser unit sits outside the house, usually on a concrete pad beside the foundation, and holds the compressor and condenser coil. Inside, the air handler or furnace-mounted evaporator coil lives in a utility space, basement, or closet. Together these two units are what a new installation places.
The refrigerant line set runs between the two units, carrying refrigerant through insulated copper tubing that a contractor routes along the exterior or through interior walls. A thermostat goes on an interior wall where it reads the living space and tells the system when to run.
The drawing shows a representative layout, and a licensed contractor determines exactly how each piece fits the conditions in 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.
