Wiegmann Associates has focused on innovative, energy saving and cost-effective HVAC solutions since 1995, when Gerry Wiegmann founded the company. Today, Wiegmann is one of the industry’s premiere national design/build mechanical contractors and an expert in value engineering.
How did we earn that status? We know how to engineer and construct HVAC systems whose price and performance we can guarantee.
We harness the power of technology as well as the power of our people. Our team, which includes three times as many engineers as most competitors, has full AutoCAD, Revit and BIM capabilities. Our dedicated Controls group designs and installs Building Automation Systems (BAS) to streamline BAS projects and eliminate subcontractor mark-ups. We also provide remote service and monitoring nationwide, and 24/7 on-call service in the St. Louis region.
And we have developed the resources and relationships to be successful nationwide. Over the years, we’ve saved our clients in 42 states many millions of dollars, both in first-cost expenses and in energy consumption, which reduces operating costs year over year.
The Wiegmann leadership team is carrying on the legacy of innovation and efficiency, combining decades of experience with fresh and technologically current ideas. We offer fresh and flexible “back-of-the-napkin-sketch” ideas that put your needs first. Bids that are responsive and workable. And installations done right the first time, on schedule and within budget.
