Here's What our Clients are Saying about LionHeart

I just want to say thank you for the team effort on all our issues. Everyone is so responsive, and their communication is amazing. You have been amazing and definitely one of the best vendors we have on this account!

Property Management, National

Thank you for your help today, it is much appreciated. Your technician, Brian, is a heck of a guy. Your entire staff, Tim, and everyone else, all a class act! Again, thank you!

Data Center, Nationwide

Rob Plane + Eric Dawson were amazing as they pulled a part off the other generator (because of a turbo system leak) to complete the load test.

Healthcare Facility, Chicago, IL

I want to give a shoutout to LionHeart, and technician, Rob Plane. This is the second time Rob was out and went above and beyond the scope of work. Rob was excellent with troubleshooting and install. He included me on everything he was doing and trained me on the material. I am very pleased with the service and professionalism. I will highly recommend LionHeart to anyone needing work.

Education Client, Chicago, IL

Rob + Eric completed the generator upgrades today and new tap box/tie controls. Both generator controls are now fully upgraded, and the hospital gained much needed emergency power flexibility for patient safety. I rarely feel compelled to acknowledge the technical expertise and workmanship of field techs performing such work, but your team was outstanding in every category! I am sure you know the value of having such employees and the difference they bring to the table when operators like us have to make decisions on who we partner with. Celebrate their performance, they represent LionHeart well above and beyond my expectations!

Medical Center, Des Plaines, IL

I have been very impressed with LionHeart’s service and maintenance practices for the last 5 years. I am also very impressed with the account management services. If all of my accounts were handled the way LionHeart handles them, my job would be simple.

Healthcare Facility, Belvidere, IL

We are so thankful for the quick response and correspondence LionHeart provided to us in our emergency. It was a pleasure working with LionHeart and I would highly recommend your services to anyone who is in dire need!


I just want to say thank you for all your help with this project. Jason Patterson has been awesome in completing all this work. It was a pleasure having him on our team, and we could not be where we are without the true partnership that everyone from LionHeart has provided.

Electrical Contractor, Chicago, IL

I was very pleased with the service that Tim Brian + Brian Allen performed. They were extremely knowledgeable and professional. I was very impressed that they came up with a temporary solution on the spot to get the ATS operational until we can get the correct repair parts. Thank you for doing what LionHeart does best! You set us above our competition!

Data Center, Nationwide

I cannot stress enough the appreciation that I have for our LionHeart tech and his dedication to not only LionHeart, but also his personal concern for individual customer service. Now a days, it is not only difficult to find someone who has the extraordinary qualifications that he possesses, but also to find someone with his dedication to customer service. He is truly amazing.

Field Service Engineer, David Myers was onsite today performing service on both pieces of equipment. I was really impressed. He is super nice, polite, knowledgeable and works very hard.

I just want to say thank you to the tech that was on site for his hard work on the ATS’s. He took time to resolve the issues on the elevators. Greatly appreciated. Thanks everyone!

Property Management, National

I don’t know if there is any way we could be more satisfied. Friendly service, on-time, great documentation, I would attribute the good condition of the equipment to the high level of PM work that LionHeart provides.

Healthcare Facility, Joliet, IL

Thank you for sending a very competent service tech out. He was able to get our generator started and functioning properly.

Construction Contractor, Romeoville, IL

The service technicians did a fantastic job installing all the new parts for the ATS upgrade. I am very impressed with their professionalism and knowledge of this work. We completed our annual fire pump testing including a transfer while flowing water, and everything transferred great. No problems!! Thank you for providing an economical solution for our 30 year old transfer switch upgrade.
