Jay Zager



The owner/operator for the past 31 years, is a wealth of knowledge in the industry. Having his humble beginnings cleaning boilers for Hawley Heating, Jay ended up buying that company and after 10 years changed it’s name to Northwest Mechanical. Jay, recognizing a need for a local distributor of modern and innovative heating products founded Thermal Products, Inc., sold Northwest Mechanical and moved solely into the position of a niche hydronic heating distributor. Having now been in the industry more than 40+ years-----If you have a question. Ask Jay!
