Takes about a minute. No obligation.
A compressor that runs only in summer and sits cold the rest of the year wears differently than one that cycles year-round. Seals dry, contactors corrode at rest, and a refrigerant leak that opened up in September goes unnoticed until the unit starts again. Homes in Garfield County, UT run cooling about two months a year, from July through August. When a contractor opens a system here, the idle months are as likely a cause as anything the compressor worked through. That shifts where the diagnosis starts: electrical contacts and refrigerant charge get checked before the compressor itself is condemned.
Ductwork in a house adapted across several equipment generations carries its history in the repairs done to it, the patches, the reroutes, the junctions added when one system gave way to another. Half the homes in Garfield County, Utah were built in 1982 or earlier (2020-2024 ACS 5-year). That span of adaptation is what a contractor is sorting through when the cabinet comes open: corroded contacts from a previous unit's chemistry, non-standard fittings left by whoever serviced it last, refrigerant lines that have been reconfigured more than once. The parts a system in that condition takes may be current, or they may require sourcing. That answer comes from what is inside, and the building's age is only the reason to expect it.
The Parts of a Central AC a Contractor Checks First
The outdoor condenser unit sits outside the house, usually on a concrete pad at ground level, and it carries the compressor and the condenser coil. These are the pieces a contractor reaches first when a system stops cooling, because a failed compressor or a damaged coil is often where the problem ends up.
Inside, the air handler holds the evaporator coil and the blower, sitting in a utility closet, basement, or attic. The two units talk through refrigerant lines that run between them, and a contractor checks those lines and their fittings alongside the electrical controls and the thermostat that tells the whole system when to run.
The drawing shows a typical central AC layout, and a licensed contractor determines which components apply to your specific home.

What the Repair Work Looks Like in Garfield 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.
Licensing Rules for Garfield County, Utah
Utah’s contractor licence does not reach alteration, repair, remodelling or improvement of a building worth less than $7,000 in labour and materials together, counting every change and addition to the agreed work — though the plumbing and electrical trades are pulled back under licensure even below that figure.
