A contractor quoting a Central AC repair in Martin County starts by asking how old the system is and whether it has been serviced, because those two things explain most failures here. 58 severe weather events were recorded in Martin County, Texas between 2015 and 2024. At that rate, severe weather is an occasional event rather than a steady grind on equipment, so a worn contactor or a failing capacitor points toward years of run time, not storm exposure. A contractor who finds a seized compressor in this county is looking hard at the unit's age and refrigerant history before anything else.
Ductwork laid in for equipment that was already old when today's units were installed tells a contractor something specific before the panel even comes off. Half the homes in Martin County, Texas were built in 1974 or earlier (2020-2024 ACS 5-year). A system that has cycled through that many summers of West Texas heat accumulates wear at the compressor, the capacitor, and the refrigerant lines in ways that are not visible from the outside. Once the unit is open, the contractor is looking at whether the failed part is a straightforward swap or the first sign of broader fatigue in components that have been running hard for a long time. Parts availability for equipment of that vintage varies, and that variation is what sets the repair scope more than the symptom that started the call.
The Parts of a Central AC a Contractor Checks First
The outdoor condenser unit sits outside the house, usually on a concrete pad along a side or rear wall, and it carries the compressor and condenser coil. These are the pieces a contractor goes to first when a system stops cooling or starts making noise it did not make before. A failed compressor, a refrigerant leak at the coil, or a seized condenser fan motor each shows up here.
Inside the house, the air handler holds the evaporator coil and the blower that pulls return air through the system. The two units connect through refrigerant lines that run between them, and a metering device on the indoor coil controls how refrigerant enters it. A frozen coil, a weak blower motor, or a blocked metering device can each cause the same symptom of weak or warm airflow, so the contractor works through them in turn.
The drawing shows a typical layout, and a licensed contractor determines exactly which components apply to the system in your house.

What HVAC Repair Looks Like in Martin 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 Martin 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 Martin County
Extreme weather puts real hours on AC equipment. A unit that runs hard through a brutal stretch accumulates wear the same way a car does miles, and repair needs in Martin County follow the local climate, not a national average.
