Duct Fabrication Built on a Legacy Since 1969

Company Overview

ANCHOR STONE is a specialized HVAC duct fabrication company dedicated to delivering high-quality, precision-engineered ductwork for commercial and industrial applications. Our duct fabrication operations trace their roots to Air Purchases Inc., a Massachusetts-based HVAC company founded in 1969, whose duct manufacturing division has served the Greater Boston area for decades. Through a strategic business restructuring, this duct fabrication business was separated and integrated into ANCHOR STONE, allowing the trade, craftsmanship, and operational experience developed over more than half a century to continue under a focused and modernized platform.

Our Heritage

The duct fabrication business now operated by ANCHOR STONE originated within Air Purchases Inc., where it was developed and refined as part of a full-service HVAC operation since 1969. While ANCHOR STONE is a newly incorporated entity, its duct fabrication activities represent the continuation of a long-standing line of business, built on decades of hands-on experience, skilled labor practices, and established production methods.

What We Do

ANCHOR STONE focuses exclusively on duct fabrication, including rectangular and round duct manufacturing, custom and project-specific duct solutions, galvanized steel and specialty metal fabrication, and shop-fabricated duct systems for commercial HVAC installations.

Corporate Clarification

References to “Since 1969” reflect the origin and historical continuity of the duct fabrication business, which was established within Air Purchases Inc. in 1969. ANCHOR STONE is a separate legal entity that continues this line of business following a lawful business separation and integration.
