Rooftop Unit (RTU) Repair

Rooftop Unit (RTU) Repair in San Antonio

Rooftop packaged units are the backbone of commercial cooling and heating across South Texas. From 5-ton units on small retail shops to 100+ ton units on warehouses and office buildings, RTUs handle the majority of commercial climate control in the San Antonio area. When one fails, the space it serves gets uncomfortable fast. Our technicians specialize in diagnosing and repairing rooftop units from every major manufacturer, including Carrier, Trane, Lennox, York, and Daikin.

San Antonio rooftop units take a beating. Summer temperatures above 100 degrees force compressors to work at peak capacity for months. Hail damage, UV degradation, and standing water accelerate component wear. Our repair process starts with a full diagnostic on the roof, not a guess from the ground. We test every component, identify the root cause, and fix it right the first time.
