Industry leader Michael Giangrandi, founder of A.J. Michaels

Michael founded A.J. Michaels in 1978. His business model was simple—to provide for his family. In order to do this he hired the best people and took care of their families. In turn we took great care to provide the best service for our customers and their families. It was a win win philosophy for all.

This is why A.J. Michaels has won more industry awards than anyone. We’re the only HVAC contractor in Maryland to win the DOE’s Century Club award for their dedication to energy efficiency. The only contractor to be recognized by Baltimore Gas and Electric nine consecutive years for their contributions in promoting energy efficient equipment. We’ve been rated A+ by the Better Business Bureau for 40 years and we even have a 4.5 Star Google rating.

Michael has also been very proactive in the industry. He has served on the Board of the Heating and Cooling Contractors of Maryland and was Chairman of the Maryland Alliance of Energy Contractors, which represented the contractors and consumers before the PSC in the development of the EmPower Maryland program. He has also had the honor of serving on the Maryland State HVAC Board and was appointed Chairman by the Governor.


We offer 24/7 emergency service and we don’t charge extra for evenings or weekends.

A.J. Michaels serves the greater Baltimore region, including Anne Arundel, Baltimore, Carroll, Harford and Howard counties.
