Takes about a minute. No obligation.
A central AC system in this county has not been sitting out weather events. 33 severe weather events were recorded in Wharton County, Texas between 2015 and 2024. At that rate, a contractor looking at a failed compressor, a seized contactor, or a refrigerant line showing fatigue has to weigh how much load that equipment has already absorbed before pinning the failure on a single cause. The wear a contractor finds on components like capacitors and contactors reflects a system that has been working hard for a long time, not one that gave out under ordinary conditions. That changes what gets inspected and what gets replaced.
Central AC systems running in houses this old are rarely the original equipment. Half the homes in Wharton County, Texas were built in 1980 or earlier (2020-2024 ACS 5-year). What that gap means for repair work is that a contractor opening a unit here has to identify exactly which generation of hardware is inside before sourcing anything, because the refrigerant type, the capacitor specs, and the control board design depend on the equipment, not the house. If the parts that system takes are still in distribution, the repair is straightforward. If they have moved to specialty supply or been discontinued, the job changes in scope and in cost before a single component is touched.
The Parts of a Central AC a Contractor Checks First
The outdoor condenser unit sits on a pad beside the house and holds the compressor and condenser coil, the two components a contractor goes to first when a system stops cooling. The compressor drives the whole cycle, so when it fails the system does nothing at all. A failed condenser coil or a refrigerant leak at that coil shows up as warm air through every vent in the house.
Inside, the air handler sits in a closet, attic, or utility room and holds the evaporator coil and the blower. The evaporator coil is where a frozen block of ice or a layer of grime often explains a weak or warm airflow. The blower motor moves conditioned air into the supply side of the duct system, so a failing motor makes itself known by reduced airflow or a system that runs but never reaches the set temperature. The thermostat and refrigerant lines connect these two units and are part of the same diagnostic pass.
The drawing shows the typical layout of these components, and a licensed contractor determines which of them applies to the specific system and conditions in your home.

What the repair visit looks like
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.
Licensing and Legal Requirements in Wharton County, Texas
In Texas a person may not engage in air conditioning and refrigeration contracting unless that person holds a license issued under the state air conditioning and refrigeration contractor law.
Severe Weather Events in Wharton County
Weather puts hours on HVAC equipment that an average forecast never captures. The stress that local conditions place on a central AC system is a repair question, not just a comfort one.
