Routine Maintenance Tips
for Longevity
Regular maintenance keeps your Generac generator reliable—especially when emergencies strike. Follow these tips:
Run weekly self-tests: Most units do this automatically, but verify it completes the cycle.
Check oil and fluid levels monthly: Refill or replace as needed, particularly after heavy use.
Replace air and oil filters annually: Dirty filters reduce performance and shorten engine life.
Clear debris around the unit: Keep at least 2 feet of clearance on all sides.
Schedule professional service once a year: A technician can catch issues before they cause failure.

The job was to replace a kitchen light fixture and the switches—nothing major, but the electrician who came out was actually both co-owner, which really stood out to me. They were incredibly thorough, took the time to explain everything clearly, and made sure to clean up every few minutes as he worked. On top of that, he was easy to talk to—engaging in conversation just like a friend would, which made the whole experience even better. Great service from start to finish. Highly recommended for all my friends in the area. Amanda Parker2025-05-08Trustindex verifies that the original source of the review is Google. Very professional, knowledgeable and helpful.

I can happily report that all of my interactions with Barrett, owner, and his crew have been nothing short of stellar. They came on time to walk through the house to we see what we needed. They sent an estimate and away we went. Grounded Electric is reliable, well priced, honest and communicative. In addition, to being a wonderful electric company, they are a wealth of information.
