Backing our specialists is an experienced team of researchers and technicians who have studied the issues related to pathogens. Using their global expertise, our portfolio of services addresses concerns about waterborne pathogens, and we have developed a model that first identifies and then quantifies risk, develops an action plan, implementing turnkey remediation services when needed. We then hold the gains through monitoring & control and pathogen analysis, followed by periodic reviews, including re-assessment of risks.

Our goal is to restore and boost the cooling and heating capacity of HVAC systems while providing Indoor Environmental Quality (IEQ) solutions that reduce the risk of airborne pathogens, contaminants or other environmental hazards.
Our specialized consulting team customizes the solutions to your specific HVAC operation needs and performance goals such as cooling capacity, air quality, reduction in energy cost and environmental footprint. We first benchmark your HVAC systems by conducting a performance, energy and IEQ audit, which also includes an ROI analysis. Based on the findings and your operational goals, we will suggest the best customized solutions, which can be implemented with our highly trained service technicians. Our monitoring services guarantee that the performance and ROI goals are maintained over time.
