Home Generator Service & Repair

The best certified service & repair near you!

Whether it be scheduled service or emergency repairs, Guardian Home Generators has you covered!

Standby generators are extremely reliable machines. Failures are rare, especially with today’s high-quality systems from leading manufacturers. That said, generators are still mechanical equipment with complex electrical, fuel, and engine components. When something does go wrong, it needs to be diagnosed and repaired correctly.

Guardian Home Generators provides professional generator repair services for homeowners across Grapevine and surrounding North Texas communities. When your system is down or showing warning alerts, our certified technicians are ready to respond and restore reliable backup power.

After hours and Weekend Emergency Service Calls

Generator emergencies don’t follow a 9-to-5 schedule, and neither do we. Whether it’s a midnight blackout or a holiday weekend, our team is available for after-hours generator repair when you need us most. Snow, ice, or extreme storms won’t stop us from reaching you.  Our technicians are equipped to handle the toughest conditions to get your backup power back online. If your system fails outside of normal business hours, call our emergency service line for immediate assistance and reliable protection from the elements.  NOTE:  For our safety, we cannot service units when lightning is nearby or imminent.

Certified and Manufacturer-Trained Repair Technicians

Guardian Home Generators is factory-trained and certified to repair both Generac and Kohler standby generators. We do not guess, shortcut, or swap parts unnecessarily. Every repair begins with proper diagnostics to identify the root cause, not just the symptom.

Because we work exclusively on whole-home backup generators, we understand how the generator, transfer switch, fuel system, and electrical service work together as a single system. That experience matters when troubleshooting complex failures.
