Most generator manufacturers, at minimum, require annual servicing by professional technicians in order for the warranty to remain in good standing.  Additionally, the unpredictability of Northwest Indiana’s weather means preventive servicing keeps your power generator at top-notch performance. When we install your generator, we immediately set you up on a schedule for regular maintenance work that meets your warranty and functionality needs. Your business requires your attention and time - lessen that load, and let us handle your power generator maintenance.


A fault in your generator is unlikely, but if there is an event, we arrive prepared. All you have to do is give us a call. We’re available around the clock to service your power generator—and we strive to do it all on the first trip. Our certified technicians come stocked with a broad range of service and repair parts. We provide in-warranty repairs for most manufacturers. For your convenience, we don’t just fix your unit, we also file the repair claim with the manufacturer on your behalf, so you don’t have to lift a finger—except to call. You and your business have no reason to be powerless! Call us today: 219-662-5976.

Just a note to let you know the employees that came ot our house were great. My husband is very ill & they took the time to go over everything they had done and answered all his questions with caring concern.

-Robuta A.

The whole process went smoothly, from the estimate to the generator pickup to the installation. The guys who did the install did a greay job, very professional, polite, and did a thorough job explaining the system.

-Jonathon V.

Your team that installed my 17kW was probably amongst the best example of what I would want representing my business. They were technically competent, experienced, efficient, pleasant, and overall good guys. They answered my technical questions with technical defendable answers - not personal opinions.

-Stephen S

I wanted to take a moment to express my sincerest appreciation for the quality work and professionalism we experienced when your employee came out to our home on Saturady to perform maintenance work on our Generac Home Generator.
