A contractor diagnosing central AC in Washington County has to account for what the equipment has actually been running against. 36 severe weather events were recorded in Washington County, Texas between 2015 and 2024. At that rate, severe weather is a standing feature of the local climate, and the components that absorb repeated electrical and thermal stress show it. Capacitors degrade faster under that kind of load, contactors pit and burn, and compressor windings weaken before they fail outright. A repair quote here reflects those findings, not assumptions about age.
A system running in a house built for a different era of cooling has likely been replaced at least once, which means what a contractor opens is rarely the original equipment. Half the homes in Washington County, Texas were built in 1989 or earlier (2020-2024 ACS 5-year). Ductwork laid down that long ago was sized for different equipment and has flexed through every summer since, but the sharper problem in a repair call is usually the unit itself: whether the capacitor, contactor, or refrigerant fitting it requires is still in production. When a part is discontinued, a contractor prices a repair against a replacement, and that is where the scope of the job actually gets decided.
The Parts of a Central AC a Contractor Checks First
The outdoor condenser unit sits outside the house, usually on a concrete pad at ground level, and it houses the compressor and condenser coil. These are the pieces a contractor goes to early, because a failed compressor or a coil that has lost its charge will stop the whole system cold. When the air inside stays warm no matter how long the system runs, this is often where the answer is.
Inside the house, the air handler holds the evaporator coil and the blower that pulls return air across it. The evaporator coil is a common fault point when the system runs but delivers weak or warm air, or when ice starts to form on the unit. The air handler also carries the expansion valve and the drain line, both of which a contractor checks when the coil itself looks clean.
The drawing shows a typical central AC layout, and a licensed contractor determines which components apply and what condition they are in for your specific house.

What HVAC Repair Looks Like in Washington 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.
Licensing and Legal Requirements in Washington 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.
