Takes about a minute. No obligation.
Sizing a central AC system here starts with what the equipment will actually run against, not what a catalog says about a house of that square footage. 127 severe weather events were recorded in Wheeler County, Texas between 2015 and 2024. At that rate, severe weather is a standing feature of the climate, and a contractor who ignores it when selecting equipment or planning the install is pricing for a place that does not exist. Refrigerant line routing, electrical connections, and condenser placement all behave differently when the system is regularly stressed, and a contractor working in Wheeler County factors that in before the unit is ordered.
Existing ductwork is what a contractor opens the bidding question on in Wheeler County. Half the homes in Wheeler County, Texas were built in 1971 or earlier (2020-2024 ACS 5-year). Ducts laid down in that era were sized and routed around the equipment of that time, and a new central AC system draws on them differently. Whether they carry the load cleanly, or need rerouting, is what sets the actual scope of the job. The electrical service gets the same look before anything is quoted.
What Goes Into a Central AC Installation
The outdoor condenser unit sits on a concrete pad beside the house and holds the compressor and condenser coil, the parts that shed heat to the outside air. Inside, the air handler or furnace with its evaporator coil mounts in a utility closet, attic, or basement and is the piece the blower pushes air across.
The refrigerant lines run between those two units, connecting the indoor and outdoor sides of the system. A thermostat goes on an interior wall and gives the homeowner direct control over when the system runs and at what target temperature.
The drawing shows the general layout of a central AC system, and a licensed contractor determines exactly what applies to this house.

What the Installation Actually Looks Like
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 Wheeler 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 Wheeler County
Weather patterns shape how hard a cooling system has to work and how long it lasts doing it. What happens outside in Wheeler County is part of what any new central AC installation here has to be sized and built for.
