What We Do
Commercial HVAC controls installation for North Texas new construction and retrofit. RTU, VAV, BAS integration, commissioning, and troubleshooting.
RTU Controls Wiring & Configuration
Once the unit is set and the mechanical contractor has made their connections, the controls work begins. That means running all controls wiring, mounting and wiring the controllers and field devices, configuring the sequences, and verifying the unit operates correctly from end to end.
The controls side is where most RTU problems originate — sensors wired to the wrong terminals, sequences left at defaults, controllers not communicating with the BMS. We do it right the first time so you're not debugging it during startup with the owner on-site.
We work with Trane, Carrier, Lennox, and most major RTU platforms. If the equipment is already specified, we work within it.
What's Included
- Controls wiring from unit to panel
- Controller mounting, wiring, and configuration
- Field device installation (sensors, actuators)
- Sequence programming and setpoint configuration
- BMS integration and point mapping
- Startup verification and performance testing
- Documentation and as-builts
VAV Box Installation & Commissioning
VAV boxes are the part of a commercial HVAC system that most often gets installed and never properly commissioned. The box goes in, the actuator gets wired, someone sets a minimum position, and the project moves on. Six months later the tenant on that floor is calling about comfort.
We install VAV boxes from rough-in through final commissioning. Every box is wired, programmed with the correct sequence, tested for proper operation across its full range, and verified against the mechanical engineer's design intent before we sign off on it.
That means minimum and maximum airflows set to the right values, reheat sequences that actually work, and occupancy logic that responds the way it's supposed to. Not just boxes that turn on.
What's Included
- VAV box installation and ductwork connections
- Actuator wiring and controls integration
- Sequence programming for each zone
- Minimum/maximum airflow verification
- Reheat coil and controls wiring
- Occupancy and override logic setup
- Performance testing and airflow verification
- As-built documentation for every box
Building Automation System Integration
BAS integration is what turns a collection of individual HVAC units into a building that operates as one system. Without it, your RTUs run independently, your VAV boxes don't talk to your AHUs, and your building operator is managing every piece of equipment separately.
We handle the full controls wiring, programming, and BMS integration for commercial mechanical systems. That means connecting every device to the building automation platform, mapping every point, and verifying that the system operates the way the mechanical engineer designed it to.
We work with Tridium Niagara, JCI Metasys, Siemens, Trane Tracer, and Honeywell, depending on what the project specifies. If the platform is already selected, we work within it. If it's still open, we can help scope the right fit for the project.
What's Included
- Controls wiring and panel installation
- BMS programming and sequence integration
- Point-to-point verification for all devices
- AHU, RTU, and VAV integration
- Alarm setup and notification configuration
- Scheduling and setpoint configuration
- Operator interface setup and training
- Integration documentation and as-builts
HVAC Commissioning & Startup
Commissioning is the part of a project that determines whether the building owner gets what they paid for. Done right, it's a methodical process of testing every sequence, verifying every setpoint, and documenting that the system operates to design intent. Done wrong — or skipped — it's what creates warranty calls for the next two years.
We provide full system commissioning and startup for new construction projects. That means functional performance testing of every piece of equipment, verification of controls sequences against the mechanical design, troubleshooting of anything that doesn't operate correctly, and a complete startup package handed to the owner before TCO.
We can act as your commissioning sub on projects where the GC or mechanical contractor is responsible for system startup, or we can work directly with an independent commissioning authority if the project requires third-party verification.
What's Included
- Pre-functional checklist for all equipment
- Controls testing and sequence verification
- System startup and performance testing
- Fault identification and correction
- Balancing coordination with TAB contractor
- Owner training on system operation
- Startup documentation and reports
- Punch list support through close-out
Thermostat Systems
Thermostat installation is straightforward when it's done correctly. When it's not — wrong wiring, wrong programming, no integration with the BMS — it's the thing that generates the most owner complaints after a project closes.
We install, program, and integrate commercial thermostat systems across all major platforms. Whether it's a standalone programmable thermostat or a networked system that ties into the building automation platform, we set it up correctly and verify it operates the way the building is supposed to be used.
What's Included
- Commercial thermostat installation and wiring
- Scheduling and setpoint programming
- BMS integration and network configuration
- Occupancy sensor integration
- Remote access setup (where specified)
- Verification against sequences of operation
- Owner walkthrough and training
Controls Troubleshooting & Repair
Existing HVAC control systems fail in predictable ways. Sensors drift out of calibration. Actuators wear out. Sequences that were never set up correctly accumulate workarounds until nobody knows what's supposed to happen. The building keeps running, but not the way it should.
We diagnose and repair existing control systems — finding the actual problem instead of replacing parts until something works. That means pulling trend data, reading the sequences, walking the mechanical rooms, and identifying exactly where the system is deviating from design intent.
We work on any platform: JCI Metasys, Siemens, Trane Tracer, Honeywell, Distech, or others. If it's a controls problem, we can find it.
What's Included
- System diagnostics and fault identification
- Sensor calibration and replacement
- Actuator testing and replacement
- Sequence review and correction
- Setpoint and schedule optimization
- Controller programming and reprogramming
- BMS communication troubleshooting
- Post-repair verification and documentation
FAQ
Before You Call
Do you work as a sub to mechanical contractors or direct to GCs?
Both. Most of our work comes through mechanical contractors who need a reliable controls sub for new construction projects. We also work direct with GCs on projects where controls are bid separately. Either way, the scope and process are the same.
What's your typical turnaround on a quote?
For most projects, we can turn around a quote within 24–48 hours of receiving drawings or a scope description. If the project is more complex, we'll tell you upfront how long it'll take and why.
What BAS platforms do you work with?
Tridium Niagara, JCI Metasys, Siemens Desigo, Trane Tracer, Honeywell, and Distech Controls are the most common. If the platform is already specified, we work within it. If it's open, we can help with platform selection.
Can you handle both the installation and the commissioning?
Yes. We can carry the full scope from installation through final commissioning, or we can split the work if another party is handling commissioning. We're flexible to how the project is structured.
Do you work on existing buildings or only new construction?
Both. New construction is our primary market, but we do troubleshooting and repair on existing systems and retrofit controls work where the scope makes sense for our team size.
What areas do you cover?
North Texas is our primary market — DFW and surrounding areas. We'll travel for the right project. If you're outside DFW, reach out and we'll tell you whether it works.
Have a project coming up?
Tell us what you're building. We'll scope it, give you a straight number, and show up ready to execute.
