A contractor called out to repair a central AC unit in Jefferson County has to settle one question before the diagnosis means anything: which components failed because the system aged out, and which carry wear from weather the equipment has been running against for years. 193 severe weather events were recorded in Jefferson County, Florida between 2015 and 2024. At that rate, severe weather is a routine condition here, not an occasional disruption, and it shows up in capacitors, contactors, and other parts that absorb electrical and thermal stress each season. A repair that skips that distinction may fix the presenting symptom and miss the next failure sitting behind it.
Ductwork in a house ages on its own schedule, and seals, flex joints, and trunk connections installed for earlier equipment do not automatically suit what runs through them today. Half the homes in Jefferson County, Florida were built in 1987 or earlier (2020-2024 ACS 5-year). When a contractor opens a failed compressor or a leaking coil, what the repair costs is one question; whether the duct system will deliver what the repaired unit produces is a separate one that the same visit has to answer. A repair that restores the equipment without checking what carries the air can leave the homeowner with a working unit and a losing system.
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 is where heat gets expelled. When it fails, the system runs but never cools. The indoor air handler or furnace cabinet lives in a closet, attic, or utility room and pushes conditioned air through the home. A fault here often shows up as weak airflow or warm air at the vents.
The evaporator coil sits inside that indoor cabinet, and a refrigerant line set connects it to the outdoor unit. The thermostat, mounted on an interior wall, is the control point for the whole system and is one of the first things a contractor checks when the complaint is that the system will not respond or cycle correctly.
The drawing shows a typical layout, and a licensed contractor determines which components apply to your specific system and home.

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.
