The Rasmussen Mechanical Difference

As a one stop shop for all of your mechanical equipment needs we can ensure all components of your facility are operating efficiently and safely.

Rasmussen became my “one stop shop” for ALL my boiler needs. All I had to do was call and explain what was going on and then sit back. Parts were ordered in a timely fashion and Techs arrived when they said they would. Work was always done quickly and second to none! Great feeling knowing I have a company that has my back and has proven it over and over for the past 21 years.

Utilities Manager, Dakota Ethanol
We needed (help with) mechanical projects; welding, boiler, steam, condensate, compressed air, in different areas around our plant. Rasmussen Mechanical Services helped us evaluate our options and save us a lot of time and money to get back on line – ASAP.
Matt Stryson
Plant Engineer, Hughes Brothers Inc.
I wouldn’t recommend anyone else… We had issues that other technicians couldn't get to the bottom of so Rasmussen came in and did the repair work and followed up with preventive maintenance.
Pete McNeal

We get all of our help from Rasmussen. I can call on the phone and talk with somebody and they are local.

Jeremy Christiansen
Superintendent, Laurel – Concord – Coleridge Schools
You were by far the best outside contracting crew we have ever had the opportunity to work with. The knowledge and expertise was superior. Your guys did an outstanding job replacing our boiler's burners.
James Rucker
Maintenance Supervisor, WireCo
Rasmussen does the job right the first time.
Steve Feauto
Maintenance Custodial Supervisor, Riverside Elementary, Oakland, IA
I’ve worked in facilities all my life, for 35 years. I would recommend Rasmussen Mechanical because of their outstanding service and reliability... If my boilers break down I know who I’m going to call and who’s going to show up.
David McAtee
Director of Operations, Boystown National Research Hospital, Omaha, NE
I would recommend them to work with other people just based on the quality and craftsmanship of their work. We went from 75%-80% efficient to 92%-94% efficient. A 12%-15% gas savings for the plant.
Conrad Baldwin
Facilities Utility Planner, Kelloggs, Omaha, NE
They’ve done a tremendous job for us. Not only are they there to do a job, but they can break it down to layman’s terms, so that as an operator, I can practice what they teach me. We’ve learned from their experience so it’s kind of a win-win for all of us.
Robert Stiles
Utility Technician, Mars Petcare, Aurora, NE
They do more than what’s expected and we have one contact we can call for many different services.
John Nikkila
Utility Technician, West Pharmaceuticals, Kearney, NE
After the first boiler, we were so pleased with their service and quality that the second one was a no brainer.

Save Money Managing Cooling Tower Water Flow

We have encouraged a number of facilities to let us examine the flow rates on their cooling towers units. This way we can see if we can improve overall efficiency. Fortunately and unfortunately for facilities, we have a high success rate at finding issues. We often find some zones are overflowing, some zones are under flowing and air side velocities are all out-of-whack.

Air Handling Unit Maintenance That Gets Results

Routine AHU cleaning not only extends the life of equipment but reduces operating costs, downtime costs and troubleshooting costs. It helps mitigate the majority of these expenses because the issues are caught ahead of time.

HVAC systems are one of the largest energy consumers in most commercial buildings at about 25% of total energy use.
