New Owners, Same Exceptional Service
Exciting news—Gross Heating has new owners! Alan Ruesch has retired after more than 40 years at our company, leaving the business in the very capable hands of long-time employees Jerry Nee and Joe Mechenich. Jerry has been with us for 23 years as a service technician and service manager while Joe has 21 years of experience as a service tech and installer, including six years as a Comfort Consultant for Gross Heating.
Joe and Jerry are supported by the same staff you already know and trust—you’ll hear the same friendly voices on the phone and see the same experienced techs and installers that you’ve counted on for years.
Jerry and Joe thank Alan for building the great company they now call their own and look forward to carrying on his tradition of providing the very best in comfort for every customer.
Our Family Treats Your Family Just-Right
Gross Heating was founded by William Gross as a coal and oil business in 1925. After William died in the 1940s, his brother took over, but soon realized it was not for him and began looking for another “family” member to buy the business. That family member was employee, Mike Ruesch. The legacy was passed to Alan Ruesch, Mike’s son and also a Gross team member, in 1996 and the company continued to flourish under his leadership for almost 25 years. In early 2019, Alan retired and sold the business to Jerry Nee and Joe Mechenich.
At Gross Heating, our employees are family. And we know our customers feel the same way. If you look at our customer testimonials, many of our team members are mentioned by name and that’s important to us. There is no one person that is the “face” of Gross Heating—that’s what sets us apart from other companies.
