Built for Performance. Focused on Service.
At AMSI Services, we’re not just fixing systems—we’re building long-term partnerships through proactive service, smarter building solutions, and a commitment to uptime.
From Small Facility to Regional Service Leader
Anderson Mechanical Services, Inc. (AMSI) was founded in 1988 with a simple mission: deliver smarter, more reliable HVAC and mechanical service to businesses across Virginia and the Mid-Atlantic.
Over the next 35 years, that vision fueled steady growth. Today, AMSI Services supports 100+ employees, executes thousands of commercial service calls per year, and operates across eight states.
In 2022, AMSI joined forces with Inspiration Plumbing to form Vertical Mechanical Group (VMG), a company designed to deliver complete mechanical solutions under one roof.
AMSI Services focuses exclusively on system performance and reliability. From commercial HVAC Systems and VRF Retrofits to BAS Controls and Preventive Maintenance Contracts, AMSI Services can support all your needs.
