Building Automation & Controls

Building Automation & HVAC Controls Service

BAS/BMS troubleshooting, controls diagnostics and mechanical system integration for commercial buildings.

When Controls Problems Look Like Equipment Problems

A building automation system ties your mechanical equipment together. When controls work well, equipment runs when it should and spaces stay comfortable without wasted energy.

When they don't, the symptoms often look like mechanical failures: units running at the wrong times, rooms that won't hold temperature, alarms that never clear, or heating and cooling fighting each other. Finding the real cause means understanding both the controls and the equipment they operate.

Controls We Work On

Troubleshooting and service across the controls that operate commercial HVAC systems:

BAS/BMS Alarms & Trends

Reviewing alarm history and trend data to pinpoint when and why faults occur.

Controllers & Networks

Controller faults and lost communication between devices and equipment.

Sensors

Temperature, pressure, humidity and CO2 sensors that read incorrectly or drift.

Actuators, Dampers & Valves

Damper and valve actuators, VAV boxes and terminal units.

Economizer & Ventilation Controls

Outdoor air, economizer and ventilation sequences.

Schedules & Sequences

Setpoints, schedules, interlocks and sequences of operation.

Common Controls Symptoms

Controls issues often show up as:

Hot and cold complaints in specific zones
Equipment running around the clock or not starting on schedule
Simultaneous heating and cooling
Alarms that repeat or never clear
Sensors reporting values that don't match conditions
Loss of communication with controllers or equipment

Controls and Mechanical Systems, Together

Controls problems and mechanical problems are often connected. Because we service the equipment as well as the controls, we can determine whether a fault starts in the hardware, the programming or the interaction between them.

Some building automation platforms require manufacturer-specific software or licensing for certain changes. We'll discuss what's involved for your system before work begins.
