A central AC compressor in Franklin County spends its life waiting for a cooling load that never arrives. Homes in Franklin County, VT have essentially no cooling season — no month of the year is warm enough to call for it. That idle time is its own form of wear: seals dry out, contactors corrode, and refrigerant can migrate when a system sits unpowered through every stretch of heat the house sees. When a compressor fails here, the contractor is not tracing the damage of heavy seasonal use. They are looking at what years of dormancy have done to the parts that were never asked to run.
Half the homes in Franklin County, Vermont were built in 1979 or earlier (2020-2024 ACS 5-year). A house that old has seen more than one system come and go, which means the equipment running in it now was fitted into ductwork and electrical service that predate it. When a central AC system fails in a house like this, what a contractor pulls out of the unit matters more than the building's age: worn contactors, degraded capacitors, refrigerant fittings from a transitional period. Parts availability is where jobs in this county get complicated, because the combination of adapted infrastructure and successive equipment generations produces failures that do not always have a current-catalog answer.
The Parts of a Central AC a Contractor Checks First
The outdoor condenser unit sits outside the house, usually on a concrete pad at the side or rear, and it holds the compressor and condenser coil. These are the first places a contractor looks when a system stops cooling. The compressor is the heart of the operation, and the condenser coil sheds heat to the outside air.
Inside the house, the air handler or furnace cabinet holds the evaporator coil and the blower fan. The evaporator coil pulls heat out of the indoor air, and the blower pushes that air through the house. The refrigerant line set connects the two units, and the thermostat tells the whole system when to run.
The drawing shows the general layout of a central AC system, and a licensed contractor determines what applies to your specific house.

What Happens When the Contractor Arrives
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 and Legal Requirements in Franklin County, Vermont
Vermont splits the trade across two specialty licences and a contractor may hold one without the other: field A1 covers automatic gas or oil heating including geo-thermal and ground source heat pumps, and field C3 covers refrigeration or air conditioning including air-to-air heat pumps.
Vermont reaches HVAC work through its electricians’ licence rather than an HVAC licence, and the requirement stops at the front door of a house: anyone performing electrical work in Vermont must be licensed as an electrician unless the work is in a residential building containing two or fewer dwelling units.
Severe Weather Events in Franklin County
Weather puts hours on HVAC equipment. Every temperature swing, every power fluctuation from a storm, adds wear that shows up sooner or later as a repair call, and Franklin County's climate shapes that load in ways a contractor here learns to recognize.
