FAQs
Why should I consider a standby generator for my home in Loudon?
Loudon sits at the end of several TVA power distribution branches, so storms, summer heat-related demand, and occasional ice events can cause outages that last from a few hours to several days. A permanently installed standby generator automatically detects a utility loss and restores power to critical circuits—or your whole house—within seconds. This keeps HVAC, refrigerators, medical devices, well pumps, and security systems running, protects pipes from freezing, and lets you stay safely at home rather than seeking shelter or a hotel.
How do I determine the correct size (kW) generator for my home?
Sizing starts with a load calculation. Make a list of the appliances and systems you want powered during an outage (HVAC, fridge, lights, sump pump, etc.) and note their starting amps or running wattage. Add the largest motor loads first (HVAC typically 4–6 kW per ton, well pump 1–2 kW). Add 25% cushion for future loads. As a rule of thumb, most average-size Loudon homes need a 14–22 kW air-cooled unit for essential circuits, while larger homes with multiple HVAC systems may need a 24–38 kW liquid-cooled model for whole-house coverage. We provide a free on-site assessment and use manufacturer software to create a precise load sheet before recommending a model.
What permits and inspections are required for generator installation in Loudon County?
Loudon County follows the 2020 NEC with local amendments. A residential generator installation requires: (1) an electrical permit from the Loudon County Codes Department, (2) a gas/mechanical permit if connecting to natural gas or propane, and (3) final inspection(s) by the county electrical inspector. If you live inside city limits (Loudon, Lenoir City), you’ll also need a city permit. We handle all permitting, coordinate with the local utility for a meter pull if needed, and schedule the final inspection so your installation is fully code-compliant and approved.
How is the generator connected to my home’s electrical system?
We install an automatic transfer switch (ATS) between the utility meter and your main service panel—or as a sub-panel for selected circuits. When the ATS senses utility power loss, it isolates your home from the grid (preventing dangerous back-feed) and starts the generator. Once the generator reaches operating speed, the ATS transfers the home’s load to generator power in about 10–15 seconds. When utility power returns, the ATS waits for it to stabilize, switches the load back, and cools the generator down before shutting it off. All wiring is sized per NEC Article 445 and 702, and we use copper THHN conductors in PVC conduit for durability.
What routine maintenance does a standby generator require?
Manufacturers recommend service every 6–12 months or after 100-200 run hours. A standard maintenance visit includes: oil and filter change, spark-plug replacement, air filter cleaning/replacement, battery load test, valve clearance check (after 2–3 years), firmware updates, and a full system test under load. Remote monitoring sends alerts for low battery, coolant temperature, or fault codes. Enrolling in our annual maintenance plan keeps your warranty valid, ensures the unit starts when needed, and often lowers homeowners-insurance premiums.
What fuel options are available and which is best for Loudon residents?
Most local homeowners choose (1) natural gas, (2) propane (LP), or (3) diesel. Natural gas is the most convenient if you have LUB or LCUB gas service—no refueling, lower emissions, and extended run time. Propane is ideal for rural homes without gas lines; a 250- to 500-gallon tank gives 5-10 days of runtime before needing a delivery. Diesel generators are typically larger (>30 kW) and favored for farms or commercial sites; they deliver high torque but need treated fuel and more frequent maintenance. We evaluate available utilities, desired runtime, and budget to recommend the optimal fuel source and tank size.
