About Us

Greendot Heating & Air Conditioning has been a trusted name in Brunswick, New Hanover, Onslow, Pender, and Columbus counties since 1998. We specialize in heating, air conditioning, refrigeration, and electrical services for homes and businesses. Using the most innovative mechanical systems, we keep North Carolina cool while delivering healthy indoor environments.

While we know a thing or two about how to keep you comfortable in the Southern climate, Greendot owner John Power gained his knowledge working all around the globe. He grew up in Ireland determined to be successful. The first step to achieving his goal came when John was accepted to a prestigious English building institute, serving in the British military at the same time.

John’s first role in the HVAC industry was with Carrier International, where he put his engineering skills to good use on the road and around the world.

In order to continue developing his know-how and grow as an industry leader, John accepted a position as a regional manager at York International based in Saudi Arabia. Shortly thereafter, he made his first trip across the pond to work for Liebert Corporation, a global manufacturer of cooling and infrastructure management systems based in Columbus, Ohio.

John returned to Ireland for several years with Liebert International before returning to the Wilmington area, originally as a partner for another HVAC company. Being able to structure his own company was his dream and to be recognized as a premier heating and air conditioning company with excellent customer satisfaction. John started his own company over 20 years ago and went into partnership to form Greendot Heating & Air conditioning close to 7 years ago. John bought out his partner in 2015 to refocus the business to concentrate on Greendot’s core values.

Ever since, Greendot has been an area leader in energy efficient HVAC solutions. We are proud to be a local business and maintain an active role in the Cape Fear Home Builders Association as well as membership in Energy Engineers and are a Star Energy and Diamond Mitsubishi dealer and distributor.

To ensure quality and top of the line performance, all of our technicians hold a North American Technician Excellence certification.  Greendot Heating & Air Conditioning is also a certified geothermal designer and installer and we’re members of the industry institution American Society of Heating, Refrigerating, and Air Conditioning Engineers (ASHRAE).
