A contractor quoting a central AC repair in Pulaski County has to settle a basic question before anything else: what actually wore this system out. 30 severe weather events were recorded in Pulaski County, Indiana between 2015 and 2024. At that rate, severe weather is a real but infrequent part of a system's working life here, which means it rarely explains a failed compressor or a refrigerant leak on its own. What contractors find instead is the usual pattern: undersized equipment, deferred maintenance, or a unit that has simply run past its useful years. The weather is worth noting; it is not worth blaming.
Ductwork fitted to a house of this vintage was sized and routed for whatever cooling existed then, and the refrigerant lines, electrical connections, and internal components of systems running in that stock have accumulated wear through decades of Indiana summers. Half the homes in Pulaski County, Indiana were built in 1970 or earlier (2020-2024 ACS 5-year). When a contractor opens a central AC unit in a house from this era, the immediate question is whether the capacitors, contactors, or refrigerant valves it takes are parts a supplier still stocks, or whether the repair forks into a longer search. That answer decides the bill and the timeline more than any other single variable on the job.
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, which are the pieces that release heat to the outside air. When a system blows warm air or shuts down unexpectedly, a contractor goes to this unit first. A failed compressor or a dirty, damaged coil is often the source.
Inside the house, the air handler holds the evaporator coil and the blower fan. The evaporator coil sits in the path of your home's air supply and is where refrigerant does its work. The blower fan moves air across it and through the supply ducts. The refrigerant line set runs between the two units, and a contractor checks it for leaks along with the electrical controls, capacitors, and contactors that tell the system when and how to run.
The drawing shows the general layout of a central AC system, and a licensed contractor determines which components apply to your particular house and situation.

What HVAC Repair Looks Like in Pulaski 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.
Severe Weather Events in Pulaski County
Extreme weather puts real load on cooling equipment: hard starts, long run cycles, and stress on components that were already working at the edge of their rated capacity. How much of that pressure a system absorbs depends on what the local weather actually does, and Pulaski County has its own pattern.
