Since 1948, McKenney’s mission has been to meet or exceed customer expectations on every job we perform. We offer a full cycle of services with expertise in heating, ventilating, air conditioning, process piping, plumbing, building automation and control systems, as well as service and maintenance.  We’ve even developed our own in-house engineering, fabrication, installation and commissioning resources to ensure cost-effective delivery of the highest quality solutions. 

With offices in Atlanta and Charlotte, McKenney’s has grown to become one of the largest mechanical contractors in the United States and is consistently ranked among the top contractors on ENR’s top Specialty Contractors list.  While we’re proud of this accomplishment, we believe that true credibility comes from upholding our reputation for service and satisfaction.   We know that every project—whether large or small—is the most important job for our customers, and that every thermostat change and service call makes a difference for owners, managers, occupants and the facilities themselves.
