Gunn & Pegelow has been representing premier HVAC manufacturers since 1954. We believe the hallmarks of our success are ongoing field support, training, and partnership with our customers. Originally representing Reznor products into Chicagoland, Northern Illinois, and into the Fox Valley region of Eastern Wisconsin, Gunn & Pegelow now represents several manufacturers throughout Illinois, Wisconsin, Upper Michigan, Indiana, and Eastern Missouri.  

Off-the-shelf products we represent are supported by the best HVAC wholesale distributors in the markets they serve, backed by local support staff and equipment and parts stock for counter pick-up availability.

When it comes to built-to-order equipment, you can count on years of experience backed by local, regional, and national support to address your project needs.

Our vision is to become the key partner to our manufacturers and our customers by utilizing our skills, our experience and our knowledge. We believe success will come by providing:

• The highest efficiency equipment available in the market today.
• Applicational knowledge about the products we represent to improve the efficiency and sustainability of a building at a value recognizable by the end user.
• Simple and best solutions for our customers along with the highest service levels possible.
• Consistent growth in opportunities and solutions that exceed both our customers’ and our manufacturers’ needs and expectations.
• A workplace that rewards the intelligent risk taking of team members that supports the benefit of the entire group.
