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.


Emergency Services

We are on call 24/7 so our preventative maintenance customers can rest assured that they will have someone ready to respond at all times.


Sizing & Design

We’ll make sure you choose the correct generator size --- often times, issues arise when a generator is undersized. That’s why we’ll carefully calculate the load requirement for your home or business.



Our technicians know generators in and out --- and we take pride in our abilities in complex troubleshooting and repairs. We are an Authorized KOHLER Generator Dealer, and can handle any and all generator repairs.
