FAQs
What types of generators do you repair in the Cookeville area?
We service virtually any residential or light-commercial generator up to 150 kW, including portable gas units, whole-house standby systems, and PTO-driven farm generators. Our technicians are factory-trained on leading brands such as Generac, Cummins, Kohler, Briggs & Stratton, Honda, and Yamaha, but we can diagnose and repair most other makes as well.
Do you provide 24/7 emergency generator repair in Cookeville?
Yes. Because many customers rely on their generators for critical power during storms or outages, we keep an on-call technician available 24 hours a day, 7 days a week. After you call our emergency line, we’ll dispatch a technician—typically within 2 hours inside Cookeville city limits and within 3–4 hours to surrounding Putnam County communities.
How much does a typical generator repair cost?
Costs vary with the fault, but most common repairs—such as replacing a carburetor, starter motor, or control board—range from $165 to $550 parts and labor. Major engine rebuilds or stator replacements can run $800–$1,800. We always perform a full diagnostic inspection first and provide a written estimate so you know the exact price before any work begins.
How often should my standby generator be serviced to prevent breakdowns?
Manufacturers recommend a full preventive maintenance service once every 12 months or after 200 running hours, whichever comes first. For frequently used commercial units, we suggest semi-annual service. Routine maintenance includes oil and filter changes, spark-plug replacement, valve adjustment, battery load testing, and software/firmware updates on newer models.
Can you handle warranty repairs and source genuine parts?
Absolutely. We are an authorized service center for Generac, Kohler, and Cummins, so we can process warranty claims, file the paperwork, and perform covered repairs at no cost to you other than any non-warranty maintenance you request. Our parts department stocks over 1,200 OEM components and can usually obtain uncommon parts within 1–2 business days.
What should I do if my generator will not start or shows an error code?
First, turn the unit off, remove any loads, and verify that the fuel supply and battery connections are secure. Check the oil level and air filter; some generators lock out when oil is low. If the unit still won’t start or displays an error code, note the code and call us with the model and serial number. Avoid repeated start attempts that can flood the engine or damage the starter. We can often walk you through a quick reset over the phone or schedule a service call if needed.
