We Can Help!

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
Council Bluffs Community School District
We get all of our help from Rasmussen. I can call on the phone and talk with somebody and they are local.
Roger Grimm

Rasmussen Mechanical is a key partner in our school district's efforts to maintain effective and efficient mechanical systems.
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.

Utility Technician, Riverside Lodge, Grand Island, NE

Complete Boiler Retube

RMS removed 484 existing tubes and the rear tube sheet from a boiler at a global food corporation. The burner and refractory were also removed. For an increase in efficiency, rifled (XID) tubes were installed mechanically and sealed by welds. A new burner cone and block refractory were also installed.

Upon completion of the boiler repairs, the unit was boiled out and the burner was tuned for efficiency.

HVAC System Redesign And Install

RMS was contracted to renovate a retail facility that was built in 1906 and convert it into The Hotel Sturgis. This required a complete HVAC re-design for the 22-room facility, as well as for the coffee shop and lobby. Old dilapidated equipment was removed and replaced with ultra-high efficiency equipment. We installed exhaust systems for bathrooms as well as venting for dryers. Design, sheet metal, HVAC, and ventilation services were all used during this project.

Safety practices played a BIG role in preventing injury on a site that was dangerous at points due to the age of the structure. The building went from 80% efficient equipment to 95+% efficient equipment upon project completion.

Industrial Burner Tuning

Rasmussen Mechanical’s burner technicians tuning a massive duel fuel Limpsfield burner.(Natural Gas and Fuel Oil as back-up)

This burner is attached to a 3,600 BHP Cleaver Brooks boiler with Autoflame controls we installed three years prior.

As part of that project, we upgraded controls on an existing boiler. We also installed a stack economizer on the new system to assist in energy reduction. An MAU was also installed to provide tempered combustion air when the ambient temperature is below 45 de.grees F.

Ducting And MUA Installs

RMS was contracted to install 2 new make-up air units along with ducting to help balance out humidity levels in this facility. Weather was a big factor and the team had to deal with high winds, rain and ice at times. Rasmussen Mechanical worked hand in hand with the scaffolding company that would sometimes require daily modifications. The project was completed with no injuries and in about 4 months on the job site.
