Commercial Advanced Rooftop Controls (ARC)

Commercial Advanced Rooftop Controls (ARC) logo
Older inefficient rooftop units can waste thousands of dollars annually. By retrofitting those rooftop units with Advanced Rooftop Unit Controls (ARC), you can save money and make your building more comfortable.

ARC retrofits can reduce fan speeds up to 40% during the first stage of heating and cooling and 60% when no heating or cooling is needed.
  • Improved comfort
  • Improved indoor air quality
  • Remote energy monitoring and control
  • Reduced fan usage
