A compressor that sits off for the better part of the year does not coast through that time without consequence. Homes in Logan County, CO run cooling about three months a year, from June through August. Contactors corrode when they go unused, capacitors lose their charge-holding ability, and a slow refrigerant leak can go undetected until the first hot day of June when the system is asked to run hard. A contractor diagnosing a repair in Logan County checks those components first, because startup failure after a long off-season is the pattern they see.
Ductwork in a house built to mid-twentieth-century standards was sized and routed for equipment that no longer exists, and whatever runs in those walls today was adapted to fit, not designed for it. Half the homes in Logan County, Colorado were built in 1964 or earlier (2020-2024 ACS 5-year). When a contractor opens a system for repair in stock like this, the first question is whether the replacement part is still manufactured. A compressor, a metering device, a control board tied to a discontinued refrigerant line: any of those can turn a straightforward repair into a sourcing problem that changes the scope and the bill.
The Parts of a Central AC a Contractor Checks First
The outdoor condenser unit sits outside the house, usually on a concrete pad beside the foundation, and it holds the compressor and condenser coil. Both are common failure points. A compressor that has failed means the system runs but makes no cold air; a condenser coil that is fouled or damaged shows up the same way, so a contractor separates the two early.
Inside, the air handler or furnace cabinet holds the evaporator coil and the blower motor. The evaporator coil sits in the airstream above the heat exchanger and is where refrigerant does its work; a frozen coil or a refrigerant leak traces back here. The blower motor pushes conditioned air through the house, and a weak or failed motor shows up as poor airflow at every register. The refrigerant lines and the thermostat connect both sides of the system and are checked alongside the hardware they serve.
The drawing shows the typical layout of a central AC system, and a licensed contractor determines which components and conditions apply to this particular house.

What HVAC Repair Looks Like in Logan 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.
