HVAC Service & Repair

When a commercial HVAC system fails, the cost is rarely just the repair. Every hour of downtime affects employees, tenants, students, customers, and operations. TexTech Services provides commercial HVAC service and repair across Texas, with the trained technicians, stocked trucks, and same-day response capability that commercial buildings actually need. Whether your facility runs on rooftop units, split systems, package units, or chillers, our team has the experience to diagnose the problem accurately and resolve it on the first visit whenever possible.

​

Commercial HVAC Repair Built for Commercial Buildings

Commercial HVAC repair is a different discipline than residential service. The equipment is larger, the systems are more complex, and the stakes are higher when something goes wrong. TexTech Services works exclusively with commercial buildings, schools, and industrial facilities, which means every technician we send is trained on the equipment that actually keeps your building running. From small office buildings to multi-site operations, we bring the same level of expertise to every commercial HVAC repair call across Texas.

​

Same-Day Commercial HVAC Service Across Texas

Speed matters when a commercial building loses heating or cooling. TexTech Services dispatches technicians the same business day for commercial HVAC service requests across Texas, with after-hours emergency response available around the clock. Our service trucks are stocked with the parts that fail most often on commercial equipment, which means most repairs are completed on the first visit instead of stretching across multiple appointments. For facility managers who measure their day in hours of building uptime, that difference is the difference.

​

Rooftop Unit Repair and RTU Service

Rooftop units are the workhorses of commercial HVAC, and they are also the equipment most likely to need attention. TexTech Services performs full RTU repair and service on rooftop units of every major manufacturer, from compressor and fan motor failures to refrigerant issues, control board problems, and electrical faults. Our technicians are trained to diagnose rooftop unit failures quickly and accurately, and our trucks carry the contactors, capacitors, fuses, belts, and filters that account for the majority of commercial RTU repairs.

​

Commercial AC Repair and Cooling System Service

Commercial air conditioning systems work harder in Texas than almost anywhere else in the country, and they need a contractor who understands the climate. TexTech Services provides commercial AC repair across Texas for package units, split systems, and larger cooling equipment. We diagnose refrigerant leaks, compressor failures, evaporator and condenser coil problems, airflow issues, and electrical faults that keep your cooling system from performing the way it should. When the call comes in during a Texas summer, our team responds with the urgency the situation requires.

​

Commercial Heating Repair and Furnace Service

Texas winters are short but the cold snaps are real, and a commercial heating system that fails on a freezing morning is not an inconvenience, it is an operational emergency. TexTech Services services commercial heating systems including gas furnaces, heat pumps, and rooftop unit heating sections. Whether your system is failing to ignite, short cycling, producing insufficient heat, or showing fault codes you do not recognize, our technicians have the training and the parts to get your building warm again quickly.

​

Commercial Chiller Service and Repair

Chillers are the heart of larger commercial cooling systems, and chiller failures can take entire buildings offline. TexTech Services services commercial chillers across Texas, including diagnostic work, refrigerant verification, control system troubleshooting, and component repair. We work on water-cooled and air-cooled chillers across the major manufacturers, and we approach every chiller call with the precision the equipment demands.

​

Refrigerant Leak Detection and Repair

A commercial HVAC system losing refrigerant is a system that is losing capacity, efficiency, and operational life. TexTech Services performs refrigerant leak detection and repair across all commercial HVAC equipment, using electronic leak detectors and proper recovery procedures. We handle older refrigerants and newer environmentally compliant refrigerants alike, and we make sure every repair is documented for your records.

​

Building Controls and Thermostat Repair

When a commercial HVAC system runs but cannot hold setpoint, the problem is often in the controls rather than the equipment itself. TexTech Services diagnoses and repairs commercial thermostats, building automation systems, sensor failures, and control wiring issues that keep your equipment from doing what it is supposed to do. Modern commercial buildings depend on smart controls to manage energy costs and occupant comfort, and we keep those controls working the way they were designed to.
