FAQs
Why should I invest in a standby generator for my home or business in Erwin?
Erwin and the surrounding Unicoi County area experience severe thunderstorms, heavy snowfalls, and occasional utility infrastructure failures that can leave properties without power for hours or even days. A permanently installed standby generator automatically senses an outage and restores electricity within seconds, protecting refrigerated goods, heating and cooling systems, sensitive electronics, security devices, and critical business operations. In addition to peace of mind and safety, a generator can reduce long-term costs by preventing frozen pipes, water damage, and downtime-related revenue losses.
How do I determine the correct generator size for my property?
Generator capacity is measured in kilowatts (kW). To find the right size, list every circuit or appliance you want powered during an outage and add their running wattages. Large loads like HVAC systems, well pumps, or commercial-grade freezers have significant starting (surge) wattage that must be factored in as well. Optimal Performance Electrical conducts a free on-site load assessment, calculates both running and starting demands, and then recommends a generator—typically 14–22 kW for most residences and 25 kW or larger for small businesses. Oversizing is avoided to keep purchase, fuel, and maintenance costs reasonable while ensuring reliable performance.
How often does my standby generator need maintenance, and what does it include?
All major manufacturers require scheduled maintenance for warranty protection and long service life. A typical plan includes: • Weekly automatic self-exercise test (built in) • Semiannual professional checkup: inspect battery, belts, connections, transfer switch, and run diagnostics. • Annual service or every 100 engine hours: replace oil, oil filter, air filter, and spark plugs; test coolant and fuel system; update firmware. Optimal Performance Electrical offers flexible maintenance agreements, remote monitoring, and priority emergency repairs for our Erwin customers.
Will a generator power my entire property, or only essential circuits?
That depends on your goals and budget. Whole-house/whole-facility generators are sized to handle 100 % of your panel’s demand, so everything functions as if the grid were on. Many clients prefer a more cost-effective “essential load” approach, in which a smaller unit—paired with an automatic transfer switch and load-shedding modules—runs key circuits such as refrigeration, lights, HVAC fan, Wi-Fi, and medical equipment. During the load assessment we’ll present both options, explaining costs, fuel consumption, and runtime trade-offs so you can choose the coverage level that best fits your needs.
Are standby generators noisy, and do they comply with local Erwin regulations?
Modern residential and light-commercial generators are built with sound-attenuating enclosures and low-rpm engines that typically operate between 60 – 70 dB(A) at 23 ft—about the same as a normal conversation. This meets Unicoi County’s general noise ordinance limits for residential zones. If your property is in a neighborhood with HOA or stricter guidelines, we can recommend additional sound-dampening measures or placement strategies to stay in compliance and keep neighbors happy.
What is the installation process and timeline with Optimal Performance Electrical?
1. Consultation & Load Calculation (1–2 days): We visit your property, assess electrical needs, discuss fuel options (natural gas, propane, diesel), and provide a detailed quote. 2. Permitting & Utility Coordination (1–3 weeks): We handle municipal permits, utility company notifications, and, if needed, HOA submissions. 3. Site Preparation & Pad Construction (1 day): Level the area, pour a concrete pad or set a pre-cast base, and run fuel/electrical conduit. 4. Delivery & Placement (Half day): Crane or roll the generator into position. 5. Electrical & Fuel Hook-up (1–2 days): Install automatic transfer switch, connect wiring, gas line, or diesel tank, and integrate load-management modules. 6. Start-up, Testing & Training (Half day): Factory-authorized technician performs full power-loss simulation, registers warranty, and trains you on operation and remote monitoring. Barring permit delays, most residential installations in Erwin are completed within 2–4 weeks from contract signing, while larger commercial projects may take 4–6 weeks. We schedule work to minimize downtime and coordinate directly with local inspectors to expedite final approval.
