AC installation in San Marcos: what we fix

A correct AC installation starts with Manual J sizing, matched indoor and outdoor equipment, a new line set or flushed lines, a properly sized breaker and disconnect, a level pad, correct refrigerant charge by superheat and subcooling, and a commissioning test of airflow and temperature split. Skipping any of those steps is why so many new systems underperform. We do not skip them.

San Marcos customers on our AC installation

★★★★★

Installed a ductless mini split in our garage conversion. Neat work, quiet unit, and they walked us through the remote and app. Very happy.

Patricia H., San Marcos
★★★★★

Our AC quit during the hottest week of the year and they had a technician at our San Marcos home the same afternoon. Fixed a capacitor, charged exactly what was quoted. Cold air within an hour.

Maria G., San Marcos
