Sizing a central AC system in Montague County means treating the local weather record as a primary input, not an afterthought. 111 severe weather events were recorded in Montague County, Texas between 2015 and 2024. At that rate, severe weather is a standing condition of operation, and a contractor who ignores it when selecting equipment capacity and specifying installation quality is building in future problems. Refrigerant line routing, equipment placement, and unit ratings all get decided against what the system will actually face once it is running.
Ductwork laid down for the equipment of another era may not move the volume a modern central AC system needs, and the electrical service feeding it may not carry the load the new unit draws. Half the homes in Montague County, Texas were built in 1979 or earlier (2020-2024 ACS 5-year). A contractor quoting an installation here has to open that question on the ductwork side before the equipment selection means much, because a unit sized right for the house can still underperform if the distribution behind the walls was never built for it.
What a Central AC System Includes
The indoor air handler sits inside the house, usually in a utility closet, attic, or basement, and it moves air across a refrigerant coil to pull heat out of the living space. The outdoor condenser unit sits on a pad beside the house and releases that heat outside. Both pieces are part of what a contractor installs as a matched system.
The refrigerant line set runs between the two units, carrying refrigerant back and forth through insulated copper tubing. The thermostat mounts on an interior wall and is the control point for the whole system, telling it when to run and at what target.
The drawing beside this shows how these pieces relate to one another in a typical layout, and a licensed contractor determines exactly how that applies to your home.

What HVAC Installation Looks Like in Montague 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.
What Montague County, Texas Requires for HVAC Installation
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 Montague County
Weather puts a measurable load on HVAC equipment, and that load varies by location. A central AC system sized and installed for what Montague County actually experiences will run differently than one built to a generic regional standard.
