Comprehensive Controls Solutions

Our Controls capabilities span the full lifecycle of a building automation system, ensuring continuity from initial design through ongoing support.

We develop control strategies tailored to each facility’s operational needs, energy goals, and system requirements. Our engineers focus on clarity, scalability, and ease of operation, ensuring systems are intuitive for operators and adaptable over time.

Lee Mechanical modernizes legacy control systems to improve reliability, visibility, and performance. We specialize in upgrading outdated platforms while minimizing disruption to occupied facilities and critical operations.

Our teams perform complete panel and field installation, coordinating closely with mechanical construction to ensure clean integration across HVAC and building systems. This unified approach reduces handoffs, conflicts, and commissioning delays.

In-house prefabrication of control panels and assemblies improves quality control, consistency, and installation efficiency. Prefabrication also helps compress schedules and reduce onsite labor.

Controls layouts are fully coordinated using BIM to support clash detection, efficient routing, and smoother field installation, especially in complex or high-density environments.

Every controls system is thoroughly tested and commissioned to verify proper operation, sequences, and communication. Our commissioning process ensures systems perform as designed from day one.
