A contractor called out to repair a central AC unit in Taylor County has to establish what actually wore the system down before settling on a scope. 87 severe weather events were recorded in Taylor County, Iowa between 2015 and 2024. That puts severe weather in the background of any diagnosis, but not at the center of it. The county's record lands near the middle of the national range, which means the equipment here has faced real seasonal load without the kind of relentless punishment that would push weather to the front of a repair estimate. Refrigerant loss, capacitor failure, and compressor wear in this area trace more reliably to how old the unit is and how consistently it was serviced than to storm count.
Ductwork in a house built for a different era of cooling tends to carry decades of debris before a contractor ever touches the unit. Half the homes in Taylor County, Iowa were built in 1951 or earlier (2020-2024 ACS 5-year). That history shows up in the opened system: compressor coils choked by what the ducts have been shedding, drain lines backed up, airflow restricted enough that the equipment has been working harder than its condition alone would explain. A contractor repairing a central AC here opens the unit and also traces back through what feeds 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 holds the compressor and condenser coil. These are the pieces a contractor reaches first when a system stops cooling. A failed compressor or a fouled condenser coil are common reasons a central AC runs but produces no relief.
Inside the house, the air handler or furnace cabinet holds the evaporator coil and the blower that moves air through the system. The refrigerant lines connect the two units, running between the outdoor pad and the indoor cabinet. A frozen evaporator coil, a weak blower motor, or a refrigerant leak in those lines are the next places a contractor looks when the outdoor unit checks out.
The drawing shows a typical central AC layout, and a licensed contractor determines which components and conditions apply to your specific house.

What happens when the contractor comes out
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.
