Automatic Transfer Switch Services for Seamless Backup Power

When the power drops, your automatic transfer switch (ATS) is the brains behind your operation, instantly shifting your load to backup power so your facility doesn’t miss a beat. But that seamless switch only happens if your system is maintained, inspected, and ready for the fight.

At LionHeart, we service ATS systems to ensure they perform like they should. Our EGSA-certified technicians know every make, model, and setup inside out. Whether it’s transfer switch repair, maintenance, or replacement, we’ve got you covered.

“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.”
