Takes about a minute. No obligation.
The compressor in a central AC unit starts and stops through the hottest part of the year, and in Chariton County that load lands hard and fast. Homes in Chariton County, MO run cooling about three months a year, from June through August. A contractor diagnosing a failed contactor or a struggling compressor here is looking at parts that have cycled through genuine heat pressure, not just sat unused. That changes what they price first. Refrigerant leaks, contactor pitting, and condenser fan motor failures show up on systems that have worked, and the short cooling window means faults that develop late in the season sit hidden until the following June.
Ducting and wiring in much of this county were put in for systems that no longer exist, and the central AC units that replaced them have been running ever since. Half the homes in Chariton County, Missouri were built in 1968 or earlier (2020-2024 ACS 5-year). When a contractor opens a unit in stock like this, the question is often whether a replacement part is still being made, and that answer changes the repair scope before anything else gets priced. A faulty capacitor is a straightforward swap. A failed scroll compressor on a discontinued platform is a different job entirely.
The Parts of a Central AC a Contractor Checks First
The outdoor condenser unit is usually the first thing a homeowner notices, and it is also where a contractor starts. It sits outside the house and holds the compressor, condenser coil, and fan. When any of those fail, the system runs but moves no heat, or does not run at all.
Inside the house, the air handler or furnace cabinet holds the evaporator coil and the blower fan. The evaporator coil is a frequent source of trouble, whether from ice buildup, refrigerant loss, or dirt that blocks airflow. A contractor also checks the refrigerant lines that run between the two units and the expansion valve that controls refrigerant flow.
The drawing shows the general layout of a central AC system, and a licensed contractor determines which components apply to your specific house and situation.

What HVAC Repair Looks Like in Chariton 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 Chariton County
Weather puts a measurable load on cooling equipment, and that load is specific to where the equipment runs. A chart of recorded severe weather events in this county is on this page because local conditions shape how hard a central AC system works and how quickly that work catches up with it.
