McKenney's Inc

McKenney's Inc has called Atlanta home since 1948, making it one of the city's most enduring mechanical contractors with more than 75 years of continuous operation. The firm holds an Atlanta campus at 1056 Moreland Industrial Boulevard and a second office in Charlotte, North Carolina, serving commercial clients across both metros and surrounding communities. With a 4-star average drawn from 81 reviews, McKenney's self-performs engineering, fabrication, installation and commissioning entirely in-house, a vertically integrated model that sets it apart from contractors who subcontract major trades. Its service palette covers HVAC, process piping, plumbing, building automation, controls, commissioning, and energy analysis across markets that include healthcare, commercial offices, education, hospitality and mission-critical facilities.

What distinguishes McKenney's is a self-performance model built on in-house shops and a workforce trained to handle every phase of a building's life cycle, from preconstruction design through retrocommissioning and ongoing preventative maintenance. The company supports LEED certification projects, delivers DDC and pneumatic control upgrades, and offers retrocommissioning services that have earned praise from institutions including Georgia Aquarium and multiple regional healthcare systems. Clients like Cone Health, Piedmont Healthcare and the Georgia World Congress Center highlight the firm's ability to execute complex and demanding projects without stepping outside a coordinated team structure, a contrast to firms that juggle fragmented subcontractors. Emergency lines for Atlanta and Charlotte are staffed around the clock, underscoring a commitment to rapid response that reviewers in crisis situations have found reliable.
