FAQs
What size generator do I need for my Dunlap home or business?
The correct generator size depends on the total wattage of the appliances and systems you want to keep running during an outage. For most Dunlap homes, a 14–22 kW standby unit will cover essentials such as HVAC, refrigerator, well pump, and lighting. Small businesses may require 25–60 kW, while facilities with heavy machinery could need 100 kW or more. Our technicians perform a free load-calculation visit, taking into account starting (surge) and running watts, to recommend an appropriately sized unit that prevents overloads and unnecessary fuel costs.
Which fuel type—natural gas, propane, or diesel—is best for generators in the Dunlap area?
Each fuel option has advantages: • Natural gas: Taps into Dunnellon’s existing utility lines (if available), offers unlimited run-time, low emissions, and no on-site fuel storage. Perfect for most residential neighborhoods. • Propane (LP): Ideal where natural-gas service is unavailable. Propane stores indefinitely in above- or below-ground tanks and burns cleaner than diesel. • Diesel: Provides high power density and is widely used for commercial or agricultural applications. Diesel generators are fuel-efficient and handle heavy loads well but require on-site tank maintenance and produce more exhaust. We help you weigh availability, run-time needs, environmental factors, and budget to choose the best fuel source.
Do I need permits or inspections to install a standby generator in Dunlap?
Yes. Sequatchie County and the City of Dunlap require an electrical permit and, in some cases, a mechanical or zoning permit for fuel connections and setback compliance. After installation, a city or county inspector must verify that wiring, transfer switches, and fuel lines meet National Electrical Code (NEC) and local standards before the unit may be activated. Our team handles all paperwork, coordinates inspections, and ensures your system is fully code-compliant.
How often should my generator be serviced, and what does maintenance include?
Manufacturers such as Generac, Kohler, and Cummins recommend at least one comprehensive service visit per year, plus a brief self-run exercise every week (usually automated). An annual professional tune-up covers: • Oil and filter change • Air and fuel filter replacement • Spark-plug inspection (gas/propane) or injector check (diesel) • Battery load test and charger verification • Transfer-switch inspection and firmware updates • Full-load test to confirm voltage and frequency stability Regular maintenance maximizes reliability, extends engine life, and protects your warranty.
Can a new generator integrate with my existing electrical panel and smart-home devices?
Absolutely. Modern automatic transfer switches can be paired with most breaker panels, whether they’re Square D, Eaton, Siemens, or another brand. For smart homes, Wi-Fi-enabled controllers let you monitor run-time, fuel level, and maintenance alerts via smartphone apps such as Mobile Link or Kohler OnCue. We can also install load-shedding modules that prioritize critical circuits (HVAC, medical equipment) and pause non-essentials to keep your generator within capacity.
What is the typical cost and installation timeline for a residential standby generator in Dunlap?
A turnkey installation—including the generator, automatic transfer switch, concrete pad, permits, fuel hookup, and final inspection—ranges from $7,500 to $12,000 for a 14–22 kW unit. Larger whole-home or light-commercial systems can run $15,000–$40,000 depending on capacity and fuel storage requirements. Once equipment arrives, most residential projects are completed in 1–2 days; commercial systems may take 3–5 days, especially if trenching for gas or propane lines is required. We provide transparent quotes, financing options, and a firm schedule before any work begins.
