FAQs
What types of electrical generators do you supply and install in Heiskell?
We offer a full range of standby and portable generators, including natural-gas, propane, and diesel models from leading brands such as Generac, Kohler, and Cummins. Sizes range from 7 kW residential units that back up essential circuits to 150 kW+ commercial systems capable of running an entire facility. Our team will recommend the best technology based on your fuel availability, power requirements, and budget.
How do I determine the correct generator size for my home or business?
Proper sizing starts with a load calculation. For homes, we list each appliance, HVAC unit, and critical circuit to find the starting (surge) and running watts. For businesses, we review single-phase and three-phase equipment, motors, and lighting loads. After adding a 20 % safety margin, we match you with the smallest generator that can handle peak demand without overload. A complimentary on-site assessment in Heiskell is included with every quote.
Do I need permits or inspections to install a standby generator in Heiskell?
Yes. Knox and Anderson Counties require electrical and fuel permits, and most neighborhoods have zoning or HOA guidelines on setback distances and sound levels. We manage the entire permitting process: submitting drawings, scheduling electrical and gas inspections, and coordinating final sign-off. All installations comply with NEC, NFPA 37, and local building codes.
What maintenance is required to keep my generator reliable?
Standby generators should receive a professional service once a year or after every 100 hours of run time. Our maintenance plans include oil and filter changes, spark-plug replacement, battery testing, valve adjustment, firmware updates, and a full load-bank test. We also run a 15-minute weekly exercise cycle that automatically lubricates the engine and charges the battery, reducing the chance of start-up failures.
What warranty and service support do you provide?
Most residential generators come with a 5-year limited warranty covering parts, labor, and travel. Commercial units include 2-year full coverage plus 3-year major components. As an authorized dealer, we handle all warranty claims locally—no shipping parts yourself. Our 24/7 emergency service guarantees a technician on-site within 4 hours anywhere in Heiskell and the surrounding counties.
How much does a generator system cost, and are financing options available?
A turnkey residential installation (10–22 kW) typically ranges from $6,500 to $11,000, including the unit, automatic transfer switch, concrete pad, permits, and labor. Larger commercial systems vary widely, from $18,000 to $60,000+. We partner with financing providers to offer zero-down plans, low-interest loans up to 132 months, and deferred payments for the first 12 months, making backup power affordable for most budgets.
