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, in 1996 and the company continues to flourish under his leadership.
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.
Our Core Business Is Quality Heating and Cooling Installations
Our work goes far beyond basic residential and commercial heating and cooling systems. We can install any type of energy-efficient indoor comfort system, whether it’s for new construction or an existing building which has outgrown its capacity. We install quality Carrier® products that feature all the latest technologies—and have a full inventory of parts for 24/7 emergency service on all makes and models of systems. No matter your comfort needs, count on our pros here at Gross Heating.
As Milwaukee and its suburbs grow, trust our employees—the face of Gross Heating & Air Conditioning—to keep pace with your heating and cooling needs and bring you innovative ideas that work.Alan Ruesch
