FAQs
What types of generators do you recommend for homes in Cookeville?
For most residences in Cookeville we recommend standby (permanent) generators powered by natural gas or propane. They start automatically when utility power fails, can run central air-conditioning, and connect directly to your home’s electrical panel through an automatic transfer switch (ATS). Portable gasoline generators are a lower-cost option for limited power needs—typically refrigerators, freezers, lights, and phone chargers—but they require manual setup and refueling and must be positioned outdoors at least 20 ft from the house for safety.
How do I determine the right size generator for my property?
Sizing is based on the combined running and start-up wattage of the appliances and systems you want backed up. For example, a typical 2,000 sq ft home with HVAC, refrigerator, freezer, lights, and a sump pump usually needs 14–20 kW. We offer a free on-site load calculation in Cookeville: we list every essential circuit, measure starting surges, and factor in fuel type, future expansions, and budget. Undersizing leads to overload shutdowns; oversizing wastes money and fuel, so professional sizing is critical.
Do I need a permit to install a standby generator in Cookeville or Putnam County?
Yes. Cookeville (and the wider Putnam County) requires an electrical permit and, when natural gas is involved, a plumbing/gas permit. Our team handles the paperwork, submits load calculations, and schedules inspections with the City of Cookeville Building Codes Department. Failing to pull permits can void warranties and lead to fines, so we never skip this step.
How often will my generator need maintenance?
Most manufacturers call for maintenance every 6 months or after 150–200 run hours—whichever comes first. Typical service includes oil and filter change, spark plug inspection, valve adjustment, battery load test, and firmware updates on the controller. Because Cookeville’s summer heat can shorten oil life, we recommend a 6-month schedule even if you haven’t reached the hour limit. We offer affordable maintenance plans that keep your warranty valid and your generator ready for the next storm.
What is the average cost of purchasing and installing a standby generator in the Cookeville area?
Pricing depends on capacity, fuel source, and installation complexity. As a ballpark, a fully installed 14–18 kW natural-gas unit runs $9,000–$12,000. Larger 22–24 kW models that power whole-house loads range from $12,500–$15,500. Costs include the generator, ATS, concrete pad, gas piping, electrical wiring, permits, and first-year maintenance. Portable generators suitable for partial backup start around $800, but remember you’ll also need extension cords or a manual transfer switch.
How long does installation take once I place an order?
From signed contract to final inspection, the typical timeline in Cookeville is 2–3 weeks. Week 1: we secure permits, order the generator, and schedule utility locates. Week 2: our electricians prepare the site, pour the pad, and rough-in fuel and electrical connections. Week 3: we set the generator, make final hookups, program the ATS, and coordinate city inspections. Once the inspector signs off, we run a full-load test and show you how to monitor and operate the system.
