Preventive Maintenance

We’ll make sure that your generator is there for you when you need it. And that’s more than just an oil change and an air filter replacement. That means we’ll check that all components are functioning properly. We stay current on all manufacturer updates. And we perform the necessary maintenance during routine service --- not during or right after a storm.

KOHLER-Authorized Startup & Warranty

We are certified to perform KOHLER Authorized Startups and KOHLER warranty repairs. A KOHLER Authorized Startup prevents failures and voided warranties due to installation errors. We’ll also make sure your installation complies with all local and national codes.

Generator Installation & Sales

We’ll help you select the appropriate generator, transfer switch, and parts and accessories for your needs. Our office staff will provide you with a customized quote and schedule an installation over the phone or via email quickly and easily. Our installers take pride in their cleanliness and professionalism.
