About GreenDena

Greg Currence, the owner and backbone of GreenDena, established the Pasadena, MD based heating and cooling business in May of 2012. While the business itself is still young, Greg has the background of a seasoned professional in the HVAC industry.

His experience in heating and air conditioning reaches all the way back to his teen years. Greg attended the Center of Applied Technology vocational school and began to learn the heating and air conditioning business. Throughout high school and upon graduating, he worked in residential HVAC for several years. He also worked in the field of commercial/medical air compressors. From 2006-2012 he obtained heavy experience in commercial HVAC install, as well as a position as Field Supervisor and his Master's license in the field of HVAC. His passion for doing the job right and extensive knowledge of HVAC have led him to found GreenDena Inc. and become the company to call when no one else can solve the problem.

This is the experience he brings to GreenDena: 18 years working in the field, learning and performing every aspect of the heating and air conditioning business. Along with experience, he also brings a passion for his customers. Greg and his team help each other through clear communication in order to troubleshoot, understand and respond to any HVAC issues that a customer might have.

Additionally, Greg is excited about implementing "green" equipment wherever possible, not only because it's more efficient, but it saves customers money every month on utility bills.

Always a family man, Greg married in 2004 and bought a house in the Pasadena community. In October of 2009, Greg and his wife celebrated the birth of their daughter. 

When you have any heating or air conditioning need, whether it be installation, maintenance, service, or even education, GreenDena is the company to call. They are committed to providing the BEST service, the FIRST time, EVERY time.
