FAQs
What types of generators do you repair in Rockford?
Our technicians are trained to service and repair virtually every make and model used in the Rockford area, including portable gasoline units, residential standby generators (natural-gas or propane), commercial/industrial diesel sets up to 1 MW, PTO-driven farm generators, and inverter generators used on RVs or food trucks. We are factory-authorized for leading brands such as Generac, Cummins, Kohler, Briggs & Stratton, and Onan, and we stock OEM parts for rapid turnaround.
Do you provide 24/7 emergency generator repair?
Yes. Because power interruptions rarely wait for business hours, we maintain an on-call crew 24 hours a day, 7 days a week. If your generator fails, call our emergency line and a dispatcher will immediately route the nearest certified technician. Most customers inside the Rockford metro area see a tech at their site within 2–4 hours, even on holidays and weekends.
How do I know when my generator needs professional repair instead of routine maintenance?
Schedule a service visit if you notice any of these warning signs: the unit will not start or needs multiple attempts, output voltage is low or fluctuates, breakers trip under normal load, you hear knocking/metallic noises, you smell fuel or see leaks, the exhaust becomes unusually smoky, or the control panel shows fault codes. Continuing to run a generator with these symptoms can cause costly engine or alternator damage, so it’s best to shut it down and call us as soon as possible.
Will using your company void my manufacturer’s warranty?
Not at all. We are fully licensed, insured, and factory-trained on the most popular generator brands. All repairs follow the manufacturer’s prescribed procedures, use genuine OEM or warrantied replacement parts, and are logged in detail for your records. This approach keeps your original equipment warranty—and any extended warranty you may have—fully intact.
What does a typical generator repair cost, and do you provide estimates?
Costs vary with the size of the generator and the nature of the failure. Minor fixes such as starter motor replacement or battery issues often fall in the $150 – $350 range, while major engine work, alternator rewinds, or control-board replacements can range from $600 to $1,200+. Before we begin any work, our technician will perform a diagnostic inspection, explain the findings, and give you a written, no-obligation quote. If you approve the repair, the diagnostic fee is applied to the final invoice.
Can you help me prevent future breakdowns?
Absolutely. We offer customizable preventive maintenance plans for homeowners, businesses, farms, and healthcare facilities around Rockford. Plans typically include semi-annual or quarterly inspections, oil and filter changes, coolant and fuel system checks, load-bank testing, battery health verification, and firmware updates for digital controllers. Routine maintenance lowers operating costs, keeps warranties valid, and reduces the likelihood of emergency failures by up to 70%.
