See What Our Customers Are Saying
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.
Dail DailingUtilities 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 StrysonPlant 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 McNealCouncil 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 GrimmHoward County Med Center
Rasmussen Mechanical is a key partner in our school district's efforts to maintain effective and efficient mechanical systems.
Jeremy ChristiansenSuperintendent, 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 RuckerMaintenance Supervisor, WireCo
Rasmussen does the job right the first time.
Steve FeautoMaintenance 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 McAteeDirector 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 BaldwinFacilities 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 StilesUtility 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 NikkilaUtility 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.

One of the easiest ways for a business to reduce operating expenses is to increase boiler efficiency. A great place to start lowering your bills is to look at how recently you performed boiler maintenance and how efficient your commercial boiler is. The boiler draws in cool air, heats it up, and sends it out the stack. A lower stack gas temperature is ideal because the higher the temperature, the more energy leaves with the flue gas
It’s important to understand how your boiler feed water system functions, especially when trying to extend the useful life of your equipment. Low-quality boiler feed water contains impurities and gases that can damage the whole system. This will lead to a reduction in efficiency and, even worse, boiler leaks or system leaks.
A condensing boiler is a water heating system designed to retrieve energy normally released from the boiler stack as waste. Latent heat is a significant source of energy. This means condensing boilers can potentially hold an efficiency rating of up to 98% in some cases. By comparison, a traditional boiler is generally between 70-85%.
