Before a contractor can call a compressor failure a maintenance problem, they have to account for what the system has been running against. 119 severe weather events were recorded in Montgomery County, Texas between 2015 and 2024. At that rate, severe weather is a standing feature of operating a central AC unit in this area, and it shapes which components a contractor checks first. Capacitors, contactors, and refrigerant lines all carry the load from repeated electrical and thermal stress events. If those parts look sound, the diagnosis shifts to installation quality and service history.
Recent-enough housing stock changes what a repair job actually hinges on. Half the homes in Montgomery County, Texas were built in 2004 or earlier (2020-2024 ACS 5-year). A system installed into a house built around that time was likely put in well after the original construction, and replacement parts for equipment of that generation remain available. What a contractor finds once the unit is open decides the repair scope: a failed capacitor, a worn contactor, a refrigerant leak at a fitting. The building itself is unlikely to be the constraint.
The Parts of a Central AC a Contractor Checks First
The outdoor condenser unit sits outside the house, usually on a concrete pad beside or behind it, and it carries the compressor and the condenser coil. These are the pieces a contractor reaches first when the system stops cooling. A failed compressor or a fouled coil is often where the diagnosis ends.
Inside the house, the air handler holds the evaporator coil and the blower. The evaporator coil sits in the air stream above the furnace or in a dedicated cabinet, and the blower pushes conditioned air into the duct system. The refrigerant line set ties the two units together, and a clogged expansion valve or a refrigerant leak anywhere along that line will show up in how both sides perform.
The drawing shows the general layout of a central AC system, and a licensed contractor determines which components apply to your specific house.

What HVAC Repair Looks Like in Montgomery 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 Montgomery 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 Montgomery County
Storm activity puts a measurable load on central AC systems: hard startups after power interruptions, compressors running flat-out through heat spikes, and components that wear faster when the grid is unstable. Repair demand in Montgomery County follows the weather, which is why a local contractor's workload looks different here than it does somewhere else.
