Building Automation and Control Systems That Deliver Results
Optimize energy, reduce costs, and enhance building performance.
A Legacy of Expertise and Innovation
Our Story: From Hands-On to High-Tech
Founded in 2003 by Scott Schelin, Advanced Control Solutions (ACS) was spun out of a leading mechanical contractor to meet the growing demand for building automation.
Building technology has continuously evolved through history. Once operated with manual controls — turning valves and flipping switches by hand — modern buildings now use automation systems in order to integrate HVAC, lighting, security and energy management. Our goal is to reduce cost while improving the indoor environment.
We specialize in the retrofit, replacement, repair and service of old and new control systems alike. We utilize open-source, flexible platforms like Honeywell Tridium to adapt and grow with your building in a cost-effective way.
