A repair call in Hamilton County starts with the system itself. 65 severe weather events were recorded in Hamilton County, Texas between 2015 and 2024. At that rate, severe weather has touched this area but has not defined the operating life of every unit here the way a heavier record might. Age, refrigerant loss, capacitor wear, and poor original installation are what a contractor works through first, because those are what the evidence in this county points toward. A unit that has spent its life running against modest seasonal demand and still failed is telling you something about its components, not about the sky.
Ductwork laid in for an original system and then pressed into service for something installed decades later is what a contractor finds in a significant share of houses here. Half the homes in Hamilton County, Texas were built in 1965 or earlier (2020-2024 ACS 5-year). That history shows up as leaks at joints that were never meant to carry today's load, insulation that has broken down in sections, and sections that were patched rather than replaced when an earlier system was swapped out. When a repair call comes in and the unit itself checks out, the duct runs are where a contractor looks next, because that is where the actual fault often sits.
The Parts of a Central AC a Contractor Checks First
The outdoor condenser unit sits outside the house and holds the compressor and condenser coil. These are the pieces a contractor goes to early when the system blows warm air or stops running altogether. The compressor is the most-examined component in that cabinet.
Inside the house, the air handler holds the evaporator coil and the blower fan. The evaporator coil is a frequent source of trouble when airflow drops or the system ices over. The blower fan, which pushes conditioned air into the duct system, gets checked when rooms heat unevenly or airflow feels weak. Both sit in the same cabinet, and a contractor will inspect them together.
The drawing shows a typical layout, and a licensed contractor determines which components apply to your specific system and what work each one needs.

What Happens When the 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.

Severe Weather Events in Hamilton County
Storm activity puts real hours on HVAC equipment: hard startups, sustained runs, and power fluctuations that wear components faster than ordinary use does. How much of that load your system carries depends on what the weather here actually does, which is why local event history belongs on a page about repair.
