Rooftop Unit Down? We Get It Running Fast.

Rooftop package units power the HVAC systems of thousands of commercial buildings across San Antonio — from retail strip centers and restaurants to office complexes and industrial facilities. When an RTU fails, the entire building loses heating or cooling. Conquer All HVACR & Services provides fast, professional rooftop unit repair and maintenance throughout San Antonio, TX and surrounding areas.

Rooftop units are the workhorses of commercial HVAC in San Antonio. They handle extreme Texas heat, UV exposure, and year-round cycling that residential systems never face. Common RTU failures include compressor burnout, refrigerant leaks, heat exchanger cracks, economizer failures, and control board issues. Conquer All HVACR & Services technicians are trained and equipped to diagnose and repair all RTU failures quickly — minimizing downtime for your business. We carry common RTU parts on our service vehicles for same-day repairs. For units beyond economic repair, we provide new RTU installation with proper sizing, curb adaptation, and startup commissioning. We serve retail centers, restaurants, office buildings, warehouses, schools, and industrial facilities throughout San Antonio, Boerne, New Braunfels, Schertz, Seguin, and all surrounding communities. Our preventive maintenance programs keep your RTUs running efficiently and extend equipment life — reducing emergency repair costs and energy bills.
