FAQs
What size generator do I need for my Jonesborough 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 homes in Jonesborough, a 14–22 kW standby unit will cover essentials such as HVAC, refrigeration, lighting, and small electronics. Larger residences or small businesses with heavy-duty equipment may require 25–60 kW or more. Our technicians perform an on-site load assessment—measuring starting (surge) and running watts—to recommend a model that balances capacity, fuel efficiency, and budget.
How long does a typical generator installation take?
Once your unit is in stock and permits are approved, a standard residential installation usually takes one full day. This includes placing the generator pad, setting the unit, running electrical and fuel lines, installing the automatic transfer switch, and completing start-up testing. Commercial projects or complex fuel runs can extend the job to 2–3 days. We schedule inspections promptly with Washington County officials to ensure you have reliable backup power as quickly as possible.
Do you handle permits and coordination with the local utility?
Yes. Jonesborough and Washington County require electrical and, in many cases, gas permits for standby generators. Our team secures all necessary permits, submits load-shedding calculations to BrightRidge (the local utility), and schedules final inspections. We also manage Tennessee One Call to locate underground utilities before any digging, ensuring the project meets code and safety standards without you having to navigate the paperwork.
How often should my standby generator be serviced?
Most manufacturers recommend a full preventive maintenance visit every 12 months or after 100 hours of run time—whichever comes first. This service includes oil and filter changes, spark-plug replacement, valve clearance checks, battery testing, and a full system diagnostic with load-bank testing. We offer maintenance plans that comply with Generac, Briggs & Stratton, and Kohler warranty requirements, keeping your warranty valid and your generator ready for the next Jonesborough storm season.
What warranties do you offer and what do they cover?
Our residential standby generators come with a 5-year limited manufacturer’s warranty covering parts, labor, and major components such as the engine block and alternator. Commercial units typically include a 2-year parts and labor warranty, with optional 5- or 10-year extended coverage. We register your unit upon installation so the warranty activates immediately, and our factory-trained technicians perform any covered repairs with genuine OEM parts.
Do you offer financing or maintenance plans for generator purchases?
Yes. Through Synchrony and local credit unions, we provide 0 % APR promotional financing for up to 18 months, as well as fixed-rate options up to 120 months. Approval decisions are usually made within minutes. For ongoing care, customers can enroll in our Generator Guardian Plan, which spreads the annual maintenance cost over 12 low monthly payments and includes priority service, remote monitoring, and discounts on accessories and emergency calls.
