Takes about a minute. No obligation.
The compressor and condenser fan on a central AC unit take the full weight of every summer it runs. Homes in Camden County, MO run cooling about four months a year, from June through September. That means the contactor, the capacitor, and the refrigerant circuit are the components a contractor checks first on any repair call here, because those are the parts absorbing the repeated start cycles. A system that was undersized at installation gives out sooner, with less time off to slow the damage.
Half the homes in Camden County, Missouri were built in 1988 or earlier (2020-2024 ACS 5-year). A house built by that point was likely cooled by equipment that no longer has a full parts supply. When a contractor opens a central AC unit in stock this age, what they are actually resolving is whether the compressor, contactor, or control board it needs can still be sourced, or whether the search ends at a supplier who stopped stocking that line years ago. A failed capacitor on a recent unit is a same-day fix. The same failure on an older system can become a parts hunt that changes the scope of the job entirely.
The Parts of a Central AC a Contractor Checks During Repair
The outdoor condenser unit sits outside the house, usually on a concrete pad along a wall, and it houses the compressor and the condenser coil. These are the pieces a contractor reaches first when a system stops cooling, because a failed compressor or a fouled coil will shut down the whole system.
Inside the house, the air handler holds the evaporator coil and the blower motor. The evaporator coil pulls heat out of the indoor air, and the blower pushes that air through the house. The refrigerant line set connects the two units, and a fault anywhere along it, including the metering device that controls refrigerant flow, will show up as poor cooling or no cooling at all.
The drawing shows the general layout of a central AC system, and a licensed contractor determines which components apply and what work is needed in your specific home.

What HVAC Repair Looks Like in Camden 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.
