This presentation will show Facilities Management and Planning Design and Construction professionals how to identify viable opportunities for restoration for aging HVAC chilled water/hot water air handlers. After reviewing the process of identifying opportunities through proper and detailed assessment of existing equipment, the discussion will turn to how to plan which air handling units are more suitable for replacement versus restoration considering current condition and financial implications. The presentation will then delve into the return on investment for situations where air handler restoration makes sense from a condition perspective and financially.  It will demonstrate with the support of case studies: Performance improvements in CFM, Static Pressure, Cooling Capacity, corresponding energy efficiency gains and CAPEX savings. An in-depth look at the process of reconditioning the HVAC system will also be covered. Ultimately, for the right candidates and right situations, HVAC restoration is a sustainable, less disruptive, more cost-effective solution than replacement.
