FAQs
What types of generators do you service and install in Maynardville?
Our technicians are trained to work on residential standby generators (7–24 kW), commercial backup units up to 500 kW, portable gasoline or diesel sets, and PTO-driven farm generators. We are certified for major brands such as Generac, Kohler, Briggs & Stratton, Cummins, and CAT, so you can rely on us for warranty repairs, routine maintenance, and complete turn-key installations.
How quickly can you respond to an emergency generator breakdown?
For customers in Maynardville and the surrounding Union County area, we offer 24/7 emergency dispatch with an average on-site arrival time of 2–3 hours. Our service vans carry the most common replacement parts, allowing us to resolve about 80 % of no-start issues during the first visit. Priority response plans are available for medical offices, grocery stores, and other critical facilities.
Do I need a permit to install a standby generator at my home or business?
Yes. Union County requires an electrical permit and, for propane or natural-gas units, a gas permit as well. Our team handles the entire permitting process, including load calculations, site drawings, and scheduling the final inspection with the county inspector. We also coordinate with your utility provider for any needed meter or gas upgrades so you stay fully code-compliant.
How often should my generator be serviced?
Manufacturers recommend a full preventive maintenance visit every 12 months or after 100–150 run hours, whichever comes first. This includes oil and filter changes, coolant and battery checks, valve adjustments (if required), firmware updates, and a timed load-bank test. In high-use or dusty farm environments around Maynardville, we often suggest semi-annual service to keep your warranty valid and reduce unexpected failures.
What factors influence the cost of a new generator installation?
Key cost drivers include generator size (kW rating), fuel type (natural gas, propane, diesel), distance to the electrical service panel and gas line, transfer-switch rating, and site preparation (concrete pad, trenching, or grading). For most Maynardville homes, turnkey installations start around $7,500, while small businesses typically budget $15,000–$25,000 for a 50–100 kW system. We provide free on-site assessments and detailed written quotes so there are no surprises.
Are your electricians licensed and insured to work in Tennessee?
Absolutely. All of our lead technicians hold a Tennessee Limited Licensed Electrician (LLE) or Electrical Contractor (CE) license, and our company carries $2 million in general liability and workers’ compensation coverage. We stay current with NEC code changes, participate in manufacturer training each year, and are an authorized warranty service center, ensuring your project in Maynardville is handled safely and professionally.
