Cooling Systems Built for Southeast Texas Heat

Extended Southeast Texas cooling seasons strain conventional systems and run up utility costs in homes without existing ductwork or with rooms that overheat despite central air. 5 Star Construction Services installs 12,000, 18,000, 24,000, and 36,000 BTU mini-split systems matched to measured square footage, insulation quality, and sun exposure patterns. EPA-certified technicians size equipment based on actual load calculations rather than rough estimates, so indoor units maintain consistent temperatures without cycling inefficiently.

Professional installation involves mounting the outdoor compressor on a level pad or wall bracket, running refrigerant lines and electrical connections through a small exterior penetration, and securing the indoor air handler at the correct wall height for even airflow distribution. Proper refrigerant charge and vacuum procedures prevent future compressor failure and maintain manufacturer warranty coverage. Every installation includes a one-year labor warranty, and manufacturer warranties range from five to ten years depending on the specific model selected.

Schedule an on-site evaluation to determine appropriate BTU capacity and indoor unit placement for your space.

Mini-split sizing begins with measuring the area to be cooled, accounting for ceiling height, window count and orientation, insulation type, and whether the space sits above unconditioned areas like garages. A 12,000 BTU unit handles up to 500 square feet under typical conditions, while 18,000 BTU systems work for spaces reaching 750 square feet, and larger 24,000 or 36,000 BTU models serve open-plan areas or multiple connected rooms. Undersized systems run continuously without reaching set temperature, while oversized units short-cycle and fail to dehumidify effectively in humid Gulf Coast conditions.

After installation completes, you'll notice the indoor unit responds quickly to thermostat adjustments, maintains steady temperature without constant compressor noise, and removes enough moisture that the air feels comfortable rather than clammy. The outdoor unit runs in measured cycles rather than laboring nonstop during afternoon heat. Refrigerant lines remain dry and frost-free, indicating the system holds proper charge and operates within design parameters.

EPA certification matters because refrigerant handling requires specialized recovery equipment and knowledge of environmental regulations. Technicians who lack certification often overcharge or undercharge systems, leading to compressor damage that voids manufacturer coverage. Proper vacuum procedures eliminate moisture and air from refrigerant lines before charging, preventing internal corrosion and refrigerant breakdown that reduce system lifespan.
