Its dedicated service and maintenance division supports customers from initial construction and commissioning through preventative maintenance, repairs, system optimization and long-term building performance.

“As a full-service design-build mechanical contractor, we serve as a single-source partner for every phase of a project’s mechanical systems.”— Brian Sosine, Senior Vice President 

“As a full-service design-build mechanical contractor, we serve as a single-source partner for every phase of a project’s mechanical systems,” says Brian Sosine, Senior Vice President. “From in-house engineering and fabrication to project management, field installation and ongoing service, we provide seamless coordination and accountability that reduces complexity, improves efficiency and maximizes the long-term performance of our clients’ HVAC
and plumbing systems.”

United Mechanical’s success is driven by its people. As a signatory contractor, the company employs highly trained union craftsmen who receive extensive apprenticeship education and hands-on field experience through the local sheet metal and piping trades. They are supported by an experienced office team that blends seasoned industry professionals with emerging talent.

“Our culture is built on collaboration, mentorship and continuous growth,” says Sosine. “By investing in both our next generation and our experienced leaders, we’ve built a team that is innovative, highly
skilled and committed to delivering exceptional results.”

With continued year-over-year growth, United Mechanical is expanding its presence throughout the Sacramento region. Later this year, the company will relocate its Sacramento office to a facility four times larger than its current location, featuring a warehouse six times the size of its existing space to support training, storage and fabrication, giving its team the resources needed to meet the evolving needs of their customers.

“These investments reflect our long-term commitment to the region and position us to deliver even greater value through innovative, high-quality and cost-effective mechanical solutions,” concludes Sosine.
