Emjay Engineering & Construction Co

Emjay Engineering & Construction Co operates from Baltimore (21207) and serves commercial and institutional clients across Maryland, Washington DC, Virginia, Delaware, and Southern Pennsylvania. Established in 1954, this full-service mechanical contractor has accumulated more than six decades of experience in commercial HVAC installation, plumbing systems, and building renovation for industrial and healthcare facilities. The company maintains a storefront at 1706 Whitehead Road in Baltimore and responds to service calls at (410) 298-2000 Monday through Friday.

Unlike residential HVAC companies, Emjay focuses exclusively on commercial and institutional projects, providing specialized expertise in healthcare facility mechanical systems. Their website references current bidding opportunities for qualified subcontractors, indicating active engagement with large-scale renovation contracts throughout the Mid-Atlantic region. The company maintains separate divisions for commercial HVAC, commercial plumbing, and healthcare specialist services, allowing targeted responses to complex building system requirements.

Customer feedback presents a split perspective. One reviewer reported being hung up on twice when inquiring about residential construction services, while another simply noted satisfaction with completed work (a five-star endorsement reading "Ok"). A third reviewer described an incident involving a company vehicle and roadside conduct. These mixed experiences underscore the importance of clarifying scope before engaging services, as Emjay appears oriented toward commercial and institutional clients rather than residential homeowners.
