A contractor working a Central AC repair in Harris County has to establish what the system has actually been running against before they can price the job accurately. 403 severe weather events were recorded in Harris County, Texas between 2015 and 2024. At that rate, severe weather is part of the normal operating history of every system in this county, and a compressor or capacitor that failed here may have been carrying that load for years before it gave out. A quote built without accounting for cumulative wear on the affected components is a quote that misses what the contractor will find when they open the unit.
Most central AC systems running in Harris County houses today were put in well after the original build, which means the house and the equipment do not share a history. Half the homes in Harris County, Texas were built in 1988 or earlier (2020-2024 ACS 5-year). When a unit opens up, what a contractor is looking at is a system that has already outlived whatever came before it. The question that decides the repair scope is whether the part a compressor or coil or control board needs is still in production, and for equipment that has been running through Houston summers for a long time, the answer is not always yes.
The Parts of a Central AC a Contractor Checks First
The outdoor condenser unit sits outside the house, usually on a concrete pad along an exterior wall, and it carries the compressor and condenser coil. These are the pieces a contractor reaches first when the system stops cooling. A failed compressor or a coil fouled with debris are common reasons a central AC quits doing its job.
Inside the house, the air handler holds the evaporator coil and the blower, and it is usually mounted in a closet, attic, or utility room. The expansion valve and refrigerant lines run between the two units. A contractor checks the evaporator coil for ice or dirt, the blower for motor and belt condition, and the refrigerant lines for leaks or pressure problems.
The drawing shows a typical layout, and a licensed contractor will determine which parts apply to your specific home and system.

What repair work in Harris County actually 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.
What Harris County, Texas Requires for HVAC Repair
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 Harris County
Extreme weather puts real stress on central AC systems, forcing them to run harder and longer than conditions they were sized for. How often that happens here shapes how much wear local equipment accumulates and what kinds of repairs show up most.
