Service And Maintenance


Our 24/7 service department is one of the pillars of our organization. We offer a full range of service and maintenance for Siemens Talon, Johnson FX, Honeywell WEBs, Tridium Vykon, and American Auto-Matrix DDC systems. Over the past 25 years, our committed and dependable service team has earned the trust of our clients.


Reactive Maintenance

Stellar’s technical support team is well-equipped and trained to respond 24/7/365 to any emergency. We can also offer round-the-clock remote monitoring for critical facilities.


Proactive Maintenance

Regular preventative maintenance ensures your facility is operating efficiently and saving energy. It helps you maximize your system’s useful life and minimize unscheduled or unplanned breakdowns – which can be highly disruptive and expensive. Properly maintained equipment also runs more efficiently. What’s more, it helps you plan and budget your maintenance costs. For some sites, safety may also be a concern.

Our customer-oriented account executives can customize a service contract that meets your needs with the goal of reducing energy consumption, maximizing occupant comfort, and increasing operational efficiency. Our service plans can include everything from onsite system training and preventative maintenance service to extended warranties and remote monitoring and diagnostics.
