A contractor diagnosing a central AC problem in Henry County has to separate what the weather contributed from what time and neglect did. 107 severe weather events were recorded in Henry County, Iowa between 2015 and 2024. At that rate, severe weather is a genuine part of the load this equipment has been running against, but it falls well short of the kind of sustained battering that would, on its own, wear a compressor or a capacitor to failure ahead of schedule. Skipped filter changes and a system that was undersized at installation account for more repair calls here than the storm record does.
Ductwork in a house of this vintage was sized and routed for equipment that no longer exists, and the system running in it now has been working against that original layout ever since. Half the homes in Henry County, Iowa were built in 1968 or earlier (2020-2024 ACS 5-year). When a repair turns up a failed capacitor or a compressor running hot, the opened unit shows the symptom; what the ductwork has been doing to the system's load is a separate finding that requires its own look. A contractor who closes the call at the replaced part hands the homeowner a bill for work that will repeat.
The Parts of a Central AC a Contractor Checks First
The outdoor condenser unit sits outside the house, usually on a concrete pad along an exterior wall, and it is where heat gets pushed out of the building. The indoor air handler or furnace coil sits inside, often in a basement, attic, or utility closet, and it is where cooled air enters the duct system. These two pieces are where a contractor starts when the system stops performing.
The refrigerant lines run between the indoor and outdoor units, and a leak or blockage in them affects both sides of the system at once. The thermostat on the wall controls the whole sequence, and a fault there can look like a compressor or coil problem until a contractor rules it out.
The drawing shows a typical layout, and a licensed contractor determines what applies to this particular house and system.

What HVAC Repair Looks Like in Henry 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.
