A contractor quoting a Central AC repair in Franklin County has to establish what actually wore the system down before they can price the job. 60 severe weather events were recorded in Franklin County, Texas between 2015 and 2024. At that rate, severe weather is something equipment here encounters now and then, not a sustained load that grinds components year after year. A capacitor that has failed or a compressor running hot is far more likely to trace back to the age of the unit or how consistently it was serviced than to storm exposure. That changes what a contractor looks at first.

What a contractor pulls from an older system here often settles the job's direction before the labor estimate does. Half the homes in Franklin County, Texas were built in 1988 or earlier (2020-2024 ACS 5-year). Equipment installed in houses that old has had time to pass through more than one service cycle, and when a compressor or control board finally fails, the parts it calls for are sometimes no longer in active production. That is not a framing problem or a supply-chain complaint; it is what a repair call in stock this age regularly surfaces, and a homeowner's timeline depends on what the opened unit actually contains.

The Parts of a Central AC a Contractor Checks First

Isometric illustration of a cutaway house showing interior ductwork, an indoor air handler and furniture, connected by lines to an outdoor condenser unit on a pad.

The outdoor condenser unit sits outside the house, usually on a concrete pad beside the foundation, and it carries the compressor and the condenser coil. The compressor is where contractors look first when a system stops cooling. A failed compressor, a refrigerant leak at the coil, or a burned fan motor in that cabinet are the most common reasons a central AC goes down.

Inside the house, the air handler holds the evaporator coil and the blower. The evaporator coil is where the cooling actually happens at the air, and a frozen coil or a blocked blower motor will stop airflow just as completely as any outdoor failure. The expansion valve and the refrigerant lines that run between the two units tie the whole system together, and faults in either one send a contractor back and forth between the indoor and outdoor cabinets.

The drawing shows the general layout of a central AC system, and a licensed contractor determines which pieces apply and what condition they are in for your specific house.
