Is your HVAC operating the way it was intended to? With React, we offer a three-tiered commissioning solution designed to maximize your system’s performance. Our service includes:

  • Retro-Commissioning: Inspection of existing HVAC system
  • Re-Commissioning: Comprehensive evaluation of the system you use after the initial commissioning process takes place

HVAC inspections and evaluation should occur at least twice a year, with special attention taken in the fall before winter sets in, and in the spring before summer arrives. This ensures that your HVAC systems are operating at their most optimal level, even during the times that put excess strain on your heating and cooling systems.
