A repair quote for central AC in Waller County starts with the compressor, the coil, and the service history, because those are what drive failures here. 33 severe weather events were recorded in Waller County, Texas between 2015 and 2024. At that rate, severe weather is an occasional event for any given system, not a grinding background condition. A contactor that burns out, a capacitor that fails, a refrigerant leak that surfaces mid-summer: a contractor working through any of these is looking at installation quality and deferred maintenance before they look at storm exposure. The weather record exists, and a contractor accounts for it, but it rarely becomes the explanation.
The ductwork and wiring in most Waller County houses were sized for modern residential cooling loads, not retrofitted around them. Half the homes in Waller County, Texas were built in 1998 or earlier (2020-2024 ACS 5-year). That means a contractor opening a failed central AC unit here is chasing the component that failed, not working around a building that was never meant to carry it. The job turns on what the opened system actually contains: whether a capacitor has given out, whether a contactor is burned, whether refrigerant has leaked, and whether the part that failed is still in supply for that system.
The Parts of a Central AC a Contractor Checks First
The outdoor condenser unit sits outside the house, usually against an exterior wall, and it is often where a repair starts. Inside the cabinet, the compressor does the hardest work, and when the system blows warm air or trips a breaker, those two components are where a contractor looks first.
Inside the house, the air handler or furnace cabinet holds the evaporator coil and the blower fan. The evaporator coil pulls heat out of indoor air, and a frozen coil or a failing blower motor will show up as weak airflow or ice on the lines. The expansion valve and refrigerant lines connect these two units, and a leak anywhere along that path is a common source of lost cooling.
The drawing shows a typical layout, and a licensed contractor determines which components apply to your specific system and what each one needs.

What HVAC Repair Looks Like in Waller 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 Waller County, Texas
