What Ariosa & Company does

Ariosa & Company is a privately-held commercial mechanical contractor headquartered in Hunt Valley, Maryland, founded in 2006 by Robert Ariosa and Paul McElhiney. The firm designs, installs, and services commercial HVAC, plumbing, electrical, and broader mechanical systems for new construction, renovation, and retrofit projects across the Mid-Atlantic region, with a primary service footprint in Maryland and select projects in Pennsylvania. Core capabilities span design-build delivery using 3D Building Information Modeling (BIM) for clash detection and project coordination, full mechanical system installation (cooling towers, chillers, boilers, VRF, DOAS, air handlers), and recurring preventative maintenance via long-term Service Agreements. The firm operates a commercial electrical services division called True Power Solutions, established in late 2020, which enables integrated mechanical-electrical-plumbing project delivery. Ariosa serves a diversified enterprise client base across education, government, multi-family residential, healthcare, recreation/hospitality, and religious facility verticals, working both as a subcontractor to general contractors (Gilbane, Southway Builders, Coakley Williams, Lewis Contractors) and directly with facility owners on design-build and service engagements.

The company has scaled to approximately 100+ employees, including 50+ certified field and service technicians, and reported approaching $40 million in revenue as of its 20th anniversary in 2026, having completed over 1,000 major projects since inception. Ariosa has been recognized with the Associated Builders and Contractors of Greater Baltimore Model Member Award (2024) and multiple Diamond and Gold Excellence in Construction Awards. The firm's revenue model is primarily project-based (new construction, renovations, and retrofits bid via general contractors or design-build proposals) supplemented by recurring Service Agreement maintenance contracts. The company explicitly identifies as family-oriented and has declined private equity investment; founder Robert Ariosa has initiated formal succession planning to transition leadership to the next generation, including his son Steven Ariosa (Executive Vice President). Ariosa also contributes $50,000-$75,000 annually to community causes and emphasizes OSHA/MOSH/ISN safety certifications and LEED AP accreditation as part of its operating standards.
