About Us

Coenen Mechanical, LLC has been providing mechanical, plumbing, HVAC, fabrication, and engineering design services to industrial customers since 1997. The company was started to provide mechanical services to pulp/paper, food, energy, and general industrial customers throughout the Midwest. We have grown the business and now also serve industrial customers nation-wide on machine installation and upgrade projects involving piping and sheet metal work. In addition, we have become a supplier of pipe fabrication and skid mounted equipment for general contractors and customers across the country. Our employees have consistently worked to be the highest quality provider with the most competitive pricing.

Our commitment to our customers remains unchanged – to deliver exceptional customer service and quality workmanship at a fair price. This is a core value that the company was founded on, which we continue to focus on today. With generations of experience in the mechanical contracting industry, the employees of Coenen Mechanical have the knowledge and expertise to complete your piping, HVAC, or sheet metal project work on-time and under budget.

Coenen Mechanical’s tradespeople are experienced in process piping (steam, condensate, air, gas, water, etc.), hydraulics/pneumatics, orbital pipe welding, and all other piping associated with industry. We have an R, U, and S stamp which allows us to construct and/or repair pressure vessels and tanks including condensate tanks, dryers, receivers, etc. Coenen is recognized as a preferred supplier for several well-known engineering/equipment suppliers including steam joints, heat exchangers, water/wastewater treatment systems, and steam/condensate systems. Our sheet metal group is capable of fabricating and installing duct-work, tanks, guarding, platforms/catwalks, and other specialty metal fabrications.
