FAQs
What types of generators do you install and service in the Cookeville area?
We work with a full range of residential and light-commercial generators, including whole-home standby units (10–48 kW), larger three-phase systems for small businesses, and portable backup models. Our technicians are factory-trained on major brands such as Generac, Kohler, Briggs & Stratton, and Cummins, so we can handle new installations, warranty repairs, fuel conversions, and routine maintenance for almost any unit on the market.
How do I determine the right size standby generator for my home or business?
Proper sizing starts with a load analysis. We review your electrical panel, list the essential circuits or equipment you want powered, and calculate the total starting (surge) and running wattage. For homes, this usually ranges from 12 kW for basic essentials up to 26 kW for whole-house coverage. Businesses may need 30 kW to 150 kW depending on HVAC, refrigeration, and computer loads. After the assessment, we provide a written recommendation and estimate so you get a generator that won’t overload or run inefficiently.
What does the installation process involve and how long will it take?
A typical residential installation takes 1–2 days. Day one covers site preparation, mounting the generator pad, setting the unit, and running fuel lines (natural gas or propane). Day two involves electrical interconnection, ATS (automatic transfer switch) mounting, startup, and customer training. Commercial projects may require additional trenching, concrete pads, and utility coordination, extending the schedule to 3–5 days. We handle permits with the City of Cookeville and Putnam County and arrange final electrical and gas inspections so you have a code-compliant system.
How often does my generator need maintenance, and do you offer service plans?
Like any engine, a standby generator needs an annual tune-up and a mid-year inspection. Service includes changing the oil and filters, testing the battery and charger, inspecting belts, spark plugs, coolant, and performing a full load test. We offer Bronze, Silver, and Gold maintenance plans that bundle these visits, priority emergency response, and remote monitoring. Enrolling in a plan keeps the manufacturer’s warranty valid and greatly reduces the risk of unexpected failures during an outage.
Are permits or inspections required for generator installations in Cookeville?
Yes. The State of Tennessee requires an electrical permit, and the City of Cookeville or Putnam County must inspect the electrical and gas connections. For natural gas units, the local gas utility also performs a pressure test. We manage all paperwork, schedule inspections, and provide a copy of the passed inspection for your records and insurance company. Skipping permits can void warranties and may lead to fines or denied claims, so we make compliance a priority.
How much does a standby generator system cost and do you offer financing?
Installed pricing for a typical 18–22 kW home standby generator in Cookeville ranges from $8,500 to $12,000, including the generator, ATS, pad, fuel line, labor, permits, and first-year service. Larger commercial systems can range from $18,000 to $60,000, depending on capacity and site work. To make budgeting easier, we partner with Synchrony and Tennessee Credit Union to offer 0% APR financing for 12 months and low-interest plans up to 132 months. We also accept TVA EnergyRight rebates when available and handle all rebate paperwork for you.
