Commercial Power Generator Services

As a business owner, you know the drill. None of your equipment, procedures, or even your employees are left completely unsupervised. You take care to evaluate them and ensure everything and everyone is performing to the highest standard. The same is true for your power generator. Our certified technicians service your generator with preventive maintenance to make sure it’s operating at optimal efficiency, so your business is always prepped for any power outage at any time. Here are some of the generator brands that we service.

Most generator manufacturers require at least annual servicing by professional technicians in order for the warranty to remain in good standing. Not only that, but 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. You’ve got enough to arrange with your business—let us handle your power generator maintenance.


A fault in your generator is unlikely, but if such a thing occurs, we come 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. And we don’t just fix your unit, we file the repair 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.

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.
