Founder & CEO
Dennis founded Denair HVAC in Brooklyn in March 2007 after seven years in the HVAC service industry—starting with one man and a beat-up used truck. Over the following 19 years, he grew the company into a $2M+ operation with 28 certified technicians and a portfolio spanning Yaskawa VFD installations, commercial HVAC fit-outs, and energy management systems across all five NYC boroughs. His hands-on background in every facet of the trade—from field service to strategic growth—drives Denair's commitment to honest, results-oriented mechanical contracting. In 2019, his leadership was recognized when Denair was named to the Inc. 5000 list of America's fastest-growing companies.

VFD stands for Variable Frequency Drive. In HVAC applications, a VFD is an electronic controller that adjusts the speed of electric motors—such as those powering fans, pumps, and compressors—by varying the frequency and voltage of the electrical supply. This allows HVAC equipment to operate at precisely the speed needed to meet actual building demand, rather than running at full power continuously, resulting in significant energy savings and reduced mechanical wear.
