Rob Derksen has spent the past 32 years in the Geothermal heating and cooling industry.  Starting as a shipping clerk for a major Geothermal Distributor, Rob learned the business literally from the ground up.  He has done everything from a Territory Manager for a Geothermal Manufacturer, to Co-owning Michigan Energy Services, (an HVAC company specializing in Geothermal heat pump installations), to HERS Energy Rating, to Sales Training, and Public Speaking about home energy to homeowners and HVAC Contactors.

In 2017, Rob started D4 Consulting to develop a much-needed software package that simplifies the design and sales process for HVAC systems.  This software allows HVAC Contractors to deliver onsite proposals in a single home visit as well as provides comparisons of Geothermal and other HVAC systems to homeowners.

Rob’s well-rounded understanding of the home as a system, and his passion for education-based selling helps Customers choose products and processes that truly match their wants, needs and goals.
