HVAC Business Development expertise used to educate, inform and work with design engineers to facilitate the best solution to their applications' problems and maintaining that involvement with a project from initial design thru start-up, commissioning; and maintaining contact with the end user for any problems during the life of the equipment and systems. As there are virtually no water-side mechanical problems in the built environment, in power and industry that I have not encountered, I am available for consultation on projects that are new or an expansion of existing facilities; and those that are old, screwed up, poorly engineered, maintained and installed: condenser/cooling towers, pumps and piping, hydronic, radiant, chilled water, refrigeration systems.
