Brief history about us.

Tradition plays a large part in family business throughout the area and Wil-Mac Sales and Service provides yet another testament to the continuity which comes with such longevity.

WIL-MAC has been in the plumbing and heating business in Coldwater Mi for over 80 years. In fact, the business began in the roaring 20's when William A. McMillan, grandfather of Wil-Mac's current owner, William L. McMillan opened a plumbing and heating shop at 30 S. Monroe Street. Despite the difficulties of the depression, the business survived and thrived.

William A. McMillan raised his only child, William R. McMillan in Coldwater. He began his apprenticeship with his father after returning to Coldwater from a two-year stint in India during World War II. Eventually, the business passed on to the younger McMillan and current owner, William L., with his father retaining an active advisory role until late in his life.

There have been many changes in the plumbing and heating business in the past 80 years according to McMillan. New technologies and new environmental awareness has had great impact on techniques and materials used today. The men at Wil-Mac study current developments in their field and in the past several years have been affiliated with the Lennox Industries, which produces HVAC equipment and accessories.

Despite many changes, something's remain the same. According to McMillan, strong arms, a strong back and the ability to mimic a contortionist in close workspaces are a necessity for many jobs. Mechanical and mathematic abilities are also a must in a field that requires one to know how to figure pipe capacities, water pressures, and heat losses. Last, but not least, years of experience are an asset to anyone in the field who must cope with a wide array of government regulations, building codes, safety factors and customer desires.

WIL-MAC's mission is to provide satisfaction to the customer by delivering the highest quality service in the most cost effective way with timely delivery.
