Frequently Asked Questions
Direct Digital Control uses microprocessor-based controllers instead of older pneumatic or electromechanical systems. DDC provides more precise temperature control, better energy efficiency, and remote monitoring capability.
Yes. Most comfort complaints come from misconfigured controls, failed sensors, or improper zone balancing. We diagnose the root cause and correct it.
We prefer open-protocol systems (BACnet, Modbus) but can service proprietary platforms from Trane, Carrier, Johnson Controls, and Honeywell.
Cost varies by building size and complexity. A simple thermostat upgrade might be $500-1,500 per zone. A full DDC retrofit ranges from $3-8 per square foot.
Recent Project
La Cantera Corporate Campus: DDC Controls Upgrade
A 200,000 sq ft corporate campus near La Cantera was running on 15-year-old proprietary controllers that no longer received manufacturer support. We replaced them with open-protocol BACnet DDC controllers, reprogrammed all sequences of operation, and integrated the system with a new web-based front end. The upgrade eliminated chronic comfort complaints and reduced HVAC energy use by 18%.
