Our History

In March 1991, Alexander J Kovacs founded A J Mechanical Services by himself and one truck. He started on his own after working for a large commercial company. Alex intended to start a residential HVAC company, but the concept grew into something much larger. Once a larger commercial property management company heard he was on his own. The residential work stopped and started exclusively working in the commercial and industrial sectors. In September 1994, he purchased the property at 6250 Webster St., where the company is currently located.
