Systems we work with

Our engineers regularly service and integrate York BMS platforms alongside a wide range of mechanical assets:

• York chiller plants (sequencing, staging, condenser water, and optimization)
• York rooftop units with economizer and demand control ventilation
• VAV/VVT systems, terminal units, and zone‑level controls
• Boilers, pumps, cooling towers, and VFDs orchestrated via BACnet
• Mixed‑brand equipment from Fujitsu, Mitsubishi Electric, Midea, Gree, and Haier

Our process

• Discovery: site survey, control drawings review, and data trend capture
• Design: sequences of operation, points lists, networking, and cybersecurity posture
• Build: panel fabrication, programming, graphics, and supervised installation
• Commission: functional testing, balancing coordination, and operator training
• Optimize: analytics, FDD, and quarterly tuning for IAQ and energy KPIs

Indoor air quality and energy—no compromise

Healthy air is our mission. We align ventilation rates, filtration, and purge strategies with energy targets by using demand‑controlled ventilation, supply air temperature reset, occupancy‑based scheduling, and advanced economizer logic. The result: better IAQ, stable comfort, and measurable savings.

Industries we serve

• Office, medical, and life sciences
• Education and public buildings
• Retail centers and mixed‑use
• Hospitality and entertainment
• Industrial, logistics, and data‑adjacent environments

Common questions

Can you integrate a York BMS with existing controls?
Yes. We often bridge BACnet and other protocols to unify York equipment with mixed‑brand systems, preserving your past investments.

Do you handle retrofits without downtime?
We plan phased cutovers, temporary controls, and off‑hours commissioning to keep operations running.

How do you prove performance?
Through baselining, trend logs, FDD alerts, and KPI dashboards for energy, IAQ, and comfort—shared with your team.
