FAQs
What size generator do I need for my home or business in Heiskell?
Generator sizing depends on the total running wattage of the appliances and equipment you want to power during an outage. For most homes in Heiskell, a 14–22 kW standby unit will cover essential circuits (HVAC, refrigerator, lights, well pump, etc.). Small businesses with critical loads such as point-of-sale systems, servers, and refrigeration typically need 25–60 kW. Our technicians perform a free on-site load assessment to calculate exact requirements, preventing oversizing (higher purchase and fuel costs) or undersizing (nuisance tripping and equipment damage).
What is the difference between portable, inverter, and standby generators?
• Portable generators (2–10 kW) are gasoline-powered, manually started, and connect through extension cords or a manual transfer inlet. They are cost-effective for short outages but require refueling every 6–12 hours. • Inverter generators use advanced electronics to produce a pure sine wave, making them ideal for sensitive electronics, RVs, and job sites. They are quieter and more fuel-efficient than standard portables but offer similar power ranges. • Standby generators (10–150 kW+) are permanently installed, run on natural gas or propane, start automatically within seconds of an outage, and can power an entire home or facility. They integrate with an automatic transfer switch for seamless operation and are the preferred solution for long-duration reliability in Heiskell’s storm-prone seasons.
How long does professional installation take and what permits are required in Heiskell?
A typical residential standby installation takes 1–2 days once equipment is on site. Day 1 covers concrete pad placement, generator set-down, gas line extension, and rough electrical work. Day 2 includes wiring the automatic transfer switch (ATS), final gas hookups, startup, and customer orientation. Commercial projects may span 3–5 days depending on load-bank testing and switchgear. Anderson County and Knox County (for the Heiskell area) require an electrical permit and, when extending natural-gas service, a plumbing/gas permit. Our team handles all paperwork, coordinates utility inspections, and ensures compliance with the latest NEC and local zoning setback rules.
How often should my generator be serviced, and what maintenance programs do you offer?
Manufacturers recommend preventive maintenance every 6 months or after 200 run hours—whichever comes first. A standard service visit includes oil and filter change, spark-plug inspection, battery load test, air-filter replacement, firmware updates, and full operational exercise under load. Advanced Technology Electrical offers three plans: 1. Basic (annual tune-up), 2. Premium (biannual service with remote monitoring alerts), and 3. Critical-Load 24/7 (quarterly checks, priority emergency repair, and guaranteed 4-hour response). Enrolling in a plan keeps your warranty valid and maximizes lifespan, which commonly exceeds 20 years with proper care.
Can the generator start automatically during a power outage, and how does the transfer switch work?
Yes. When grid voltage drops below the preset threshold for about 3–5 seconds, the automatic transfer switch sends a start signal to the generator. Once the engine stabilizes, the ATS disconnects your home or business from the utility lines and transfers the load to generator power—all in under 10 seconds. When utility power returns, the ATS waits for a stable 60-second reconnection window, re-transfers the load to the grid, and signals the generator to cool down and shut off. This fully automated sequence prevents back-feeding onto utility lines and eliminates the need for manual intervention.
What fuel options are available and which is most efficient for Tennessee’s climate?
Standby units in Heiskell typically run on natural gas (NG) or liquid propane (LP). • Natural gas offers unlimited runtime as long as municipal supply is intact, lower emissions, and no on-site fuel storage. • Propane provides higher energy density, is stored in on-property tanks (100–500 gal), and is ideal for rural homes without NG lines. Diesel generators are common in commercial or agricultural settings requiring large power (80 kW+) because diesel engines deliver high torque and meet NFPA 110 standards for critical facilities. Fuel consumption averages: NG – 140 ft³/hr per 20 kW, LP – 2.1 gal/hr per 20 kW, Diesel – 1.8 gal/hr per 20 kW at full load. We help clients compare operating costs, emission profiles, and available supply lines to choose the most efficient solution for their site.
