A compressor pulled from a Fallon County home tells a particular story. Homes in Fallon County, MT run cooling about two months a year, from July through August. After standing off for most of the calendar, the contactor contacts corrode, capacitors drift, and refrigerant seals dry out. A contractor diagnosing a failed start-up here checks those components before anything else, because dormancy damages them in ways that accumulated runtime does not. The repair scope follows from what that idle period left behind.
What sits inside a central AC unit in Fallon County often tells a more specific story than the age of the house suggests. Half the homes in Fallon County, Montana were built in 1982 or earlier (2020-2024 ACS 5-year). Housing of that vintage has had time to cycle through more than one generation of equipment, and the system running today is not what the house started with. When a contractor opens a failed unit, the question that shapes the repair is whether the part it needs is still in supply. Compressor components, capacitors, and control boards for systems this old move in and out of availability, and that availability is what determines whether the job ends with a fix or a replacement conversation.
The Parts of a Central AC a Contractor Checks First
The outdoor condenser unit sits outside the house and holds the compressor and condenser coil. These are the first pieces a contractor looks at, because a compressor that has failed or a coil that is fouled or leaking will stop the system from doing its job entirely. Faults here show up fast.
Inside, the air handler or furnace cabinet holds the evaporator coil and the blower. The evaporator coil is where refrigerant does its work on the air passing through, so a cracked coil or a refrigerant shortage points back to this piece. The blower moves conditioned air into the ducts, and a failing motor or clogged wheel cuts airflow to the whole house. The expansion valve and refrigerant lines connect the two units, and a leak anywhere along those lines is a common source of a system that runs but does not cool.
The drawing shows the typical layout of these components, and a licensed contractor determines which pieces apply and what condition they are in for your specific house and system.

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 Fallon County, Montana
Montana’s contractor licence does not reach a casual, minor or inconsequential job whose total price for labour, materials and everything else is less than $2,500 — and the exemption is lost if the work is only part of a larger operation, or if a job is divided up to get under the figure.
Montana requires a current construction contractor licence from the Department of Labor and Industry: an individual or business may not engage in business as a construction contractor without one.
