What Our Clients Are Saying…

  • We are a small local church that takes pride in serving our community through God’s hands. When we were challenged with a few broken air conditioners at our church we were so blessed that Steve was able to help. He understood the importance of serving others and worked quickly with us to replace our units. It’s nice to know that there are still companies out there who truly put serving others first. 1 highly recommend using Iron Star Mechanical and will definitely work with Steve for any future needs.

  • Ironstar Mechanical developed an innovative design solution to a project with a nearly impossible deadline and tight budget.  Steve Sobolewski remained personally involved with Ownership and the subcontractors from the start of the work until the system was started…on time.  As a first experience with Steve and Ironstar, we were impressed with their ability to plan, execute and deliver exactly what they promised.

  • The team at Ironstar are problems solvers. They took the time to understand the short term and long term goals for our hotels and crafted solutions that met Ownership’s needs relative to our investment cycle. They monitored the implementation of those solutions until we were completely satisfied with the end result. Documentation was precise, communication frequent, and responsiveness was timely. Ironstar is our choice for all our mechanical and HVAC needs.
