Takes about a minute. No obligation.
A Central AC system in this county has been running against severe weather as a routine fact, not an occasional one. 387 severe weather events were recorded in Bexar County, Texas between 2015 and 2024. At that rate, components like capacitors, contactors, and compressors absorb repeated stress across every cooling season, and a contractor looking at a failed part needs to weigh accumulated load before concluding the unit was simply undersized or poorly maintained. The repair scope follows from that judgment: what looks like an isolated failure often has wear behind it that the weather record here makes unsurprising.
Half the homes in Bexar County, Texas were built in 1990 or earlier (2020-2024 ACS 5-year). A house built that long ago has already lived through more than one equipment generation, which means the system a contractor opens today was not what went in at construction. What matters in a repair is what that opened unit actually contains: whether the compressor, the capacitor, or the control board it takes are parts a supplier still stocks, or whether they have aged out of the available inventory. That answer drives the repair scope more than anything else about the house itself.
The Parts of a Central AC a Contractor Checks First
The outdoor condenser unit sits on a pad outside the house and holds the compressor and condenser coil, the two components a contractor reaches first when the system stops cooling. The compressor is the mechanical heart of the unit, and a failed one is often why a system runs but produces no relief. The condenser coil sheds heat to the outside air, and a damaged or dirty coil shows up as the system running long without results.
Inside the house, the air handler holds the evaporator coil and the blower. The evaporator coil is where the cooling effect actually reaches the air, and a frozen or leaking coil is a frequent source of problems. The blower moves conditioned air into the duct system, and when it fails the house stays warm even if the rest of the system is working. The expansion valve and refrigerant lines connect the two units, and a refrigerant leak in those lines is another common repair finding.
The drawing shows the general layout of a central AC system, and a licensed contractor determines what applies to this particular house.

What happens when a contractor comes out
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 Bexar 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 Bexar County
Extreme weather puts a measurable load on cooling equipment, and that load compounds over time. How often conditions here push a system hard is a local fact, and it shapes what repair work in Bexar County actually looks like.
