Generator Maintenance and Repair FAQ
How often should I schedule generator maintenance?
Most standby systems require service at least once per year. Many Oklahoma homeowners choose semi-annual visits for added peace of mind before summer heat and winter storms.
Are your technicians Generac certified?
Yes. Our team is Generac-trained and certified. We use OEM parts, follow factory specifications, and keep your warranty intact.
How do I know if my generator needs repair?
Watch for warning signs such as unusual noises, failure to start, frequent error codes, visible leaks, or power output issues. If your generator is not performing as expected, professional diagnostics and repair are recommended.
Can you repair all generator brands and models?
Yes, our trained technicians can repair most major brands and models, including Generac, Kohler, Cummins, and others. We always use quality parts to maintain reliability and warranty coverage whenever possible.
Is there a warranty on repair work?
Yes, all generator repair services are backed by a warranty for parts and labor. Details vary by service, so please ask your technician or office staff for specifics on your repair.
What happens if I skip generator maintenance?
Skipping maintenance increases the risk of failure during an outage. Batteries can die, fuel systems clog, and error codes go unnoticed, leaving your generator unable to start when needed.
Do you offer maintenance plans?
Yes. We offer annual and semi-annual home generator maintenance plans. These plans include scheduled service visits, reminders so you never miss routine maintenance, and the flexibility to choose what works best for your needs. Regular maintenance is the best way to protect your investment and ensure your generator is ready to perform when you need it most.
