 January 21, 2022

Started in 1986, in Nashua, NH in a old bakery building, Viking Controls established direct relationships with a number of control products manufacturers including Johnson Controls, Honeywell, Powers, Robertshaw, Erie Controls, System Sensor, Emglo, Macurco, Grasslin and others. Our specialty from the beginning was to provide complete control systems to the HVAC industry including products, system design, supervision, installation and service. With our geographic area effectively being New Hampshire and Massachusetts, we have provided all types of controls from pneumatics, electric, electronic and direct digital controls.

Over the years we became a company of more than 20 people dedicated full time to the application of control products. We have now provided controls for thousands of jobs from small projects to very large. As technology developed so did we. Our company is fully networked and computerized. Many of our control systems today are based on direct digital controls (DDC) networked to building owners computer operator workstations. We provide off-site capability to dial-up and/or connect over the internet to monitor the buildings control systems.
