About Us

Trust is Everything

NorthStock (formerly H-Mac Systems) was established in 2003 to serve as a reliable source for commercial/industrial HVAC equipment and parts. We started in a modest, windowless office with a handful of manufacturers and a strong desire to make a contribution to the Heating, Ventilating, and Air Conditioning industry. Today we are one of the country’s leading e-commerce HVAC distributors, stocking thousands of name- brand products in our purpose-built office/warehouse facility located in Southborough, Massachusetts.

Since the beginning in 2003, customer focus has driven everything we do. We are always working to provide better value through our broad offering of HVAC equipment and parts (over 400,000 and counting), easy-to-find detailed product info, simple ordering process, clear and consistent status updates, and streamlined support systems. All available online 24 hours a day, 7 days a week.
