Who We Are

John Stack Sales Company is comprised of tenured staff and sales representatives with extensive product experience and industry knowledge. As a manufacturer's representative agency, we are responsible for marketing, training, and technical troubleshooting for various product offerings of our HVAC and plumbing manufacturing partners. 

We are committed to the continued growth and advancement of the industry in New England and the Mid-Atlantic states. Although we sell through wholesale distribution, the installing contractor is the main focal point of our time and effort.


We offer both residential and commercial products, tools, and accessories to fit all of your HVAC and Plumbing needs. To get in touch with a representative in your area, visit the "Our Team" page, or click here.
