Preventive maintenance is an important part of your home generator investment. Particularly in the grueling Northwest Indiana climate, your home generator needs regular servicing to ensure it's running smoothly. Many manufacturers recommend or may require regular professional servicing of your unit to keep the warranty in standing. When we install your power generator, we’ll immediately set you on a schedule for regular maintenance work, so you don’t have to worry about making an appointment yourself. Additionally, we offer Priority Maintenance Plans as well as Manufacturer extended warranties to suit your needs.


Our skilled technicians arrive prepared. We can fix just about any power generator on the first call. Our professional technicians stock their service trucks with plenty of supplies and an extensive selection of parts. Even if you didn’t buy the generator from us, we can still service your unit. We provide in-warranty repairs for just about any manufacturer. We’ll will also file the manufacturer claim on your behalf once we’ve finished the repairs. Most manufacturers require documentation of your generator’s servicing, so we’re happy to take that responsibility off your shoulders.

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.

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.
