Takes about a minute. No obligation.
A compressor or condenser fan that fails in this area has been working against real and repeated weather load, and a contractor accounts for that before settling on a cause. 174 severe weather events were recorded in McLennan County, Texas between 2015 and 2024. At that rate, severe weather is part of the normal operating life of equipment in this county, not an occasional variable. A contractor checking a central AC repair here will look at the components that absorb that load, including capacitors, contactors, and refrigerant charge, before assuming a simple fix. What the system has been through shapes what the repair scope turns out to be.
Ductwork and electrical in housing this old were put in for a specific load, and what sits on those foundations today has been swapped, adapted, and patched across multiple replacement cycles. Half the homes in McLennan County, Texas were built in 1983 or earlier (2020-2024 ACS 5-year). When a central AC system in stock like this opens up, what a contractor finds often includes components from product lines that have been discontinued or substantially redesigned. Sourcing the right part then drives the timeline more than the diagnosis does.
The Parts of a Central AC a Contractor Checks First
The outdoor condenser unit sits outside the house, usually along a side or rear wall, and is where heat is released to the outside air. Inside, the air handler or furnace cabinet holds the evaporator coil, which is the piece that actually cools the air passing through it. When a repair call comes in, these are the first places a contractor looks.
The refrigerant lines run between the outdoor unit and the indoor coil, and the expansion valve sits in that path controlling flow. The blower fan inside the air handler pushes conditioned air into the duct system, and the thermostat on the wall is what tells all of it when to run. A fault in any one of these can bring the whole system down.
The drawing shows a typical layout, and a licensed contractor determines which parts and conditions apply to your specific home.

What HVAC Repair Looks Like in McLennan 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 McLennan 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 McLennan County
Extreme weather puts stress on central AC systems long before a breakdown shows up. How hard equipment works, and how fast it wears, is a local question shaped by what the climate here actually does.
