FAQs
What types of generators do you install and service in Rogersville?
We work with a full range of residential and light-commercial standby generators, including natural gas, propane, and diesel units from leading manufacturers such as Generac, Kohler, and Briggs & Stratton. Whether you need a compact 8–10 kW system for essential circuits or a 60 kW three-phase unit for a small business, our licensed electricians can size, install, and maintain it for you.
How do I determine the right size generator for my home or business?
Proper sizing starts with a load calculation. Our technician will visit your property, list the appliances, HVAC equipment, and critical electronics you want to power, and measure their start-up (surge) and running wattage. We then add a safety margin and select a generator that can handle the total load without being oversized. A correctly sized unit runs more efficiently, costs less to operate, and lasts longer.
What is the installation process and how long does it take?
A typical residential installation involves: (1) on-site assessment and permitting, (2) preparing a level concrete or composite pad, (3) placing and anchoring the generator, (4) running electrical conduit and fuel lines, (5) installing an automatic transfer switch, (6) final wiring, fuel hookup, and testing. Most homes are completed in one to two days once permits and materials are ready. Larger commercial jobs may take three to five days.
Do you offer preventive maintenance plans, and why are they important?
Yes. Our annual and semi-annual maintenance plans include oil and filter changes, battery checks, spark-plug replacement, coolant flushes (for liquid-cooled units), software updates, and a full operational load test. Regular maintenance prevents unexpected shutdowns, keeps your warranty valid, and extends equipment life. Customers on a plan also receive priority scheduling and discounted repair rates.
What kind of warranty and customer support do you provide after installation?
All new generators come with a manufacturer’s warranty—typically five years or 2,000 hours for residential models. In addition, we provide a one-year labor warranty covering our workmanship. If you ever have an issue, our local Rogersville support line is staffed 24/7, and our factory-trained technicians carry genuine parts to resolve most problems on the first visit.
Do you provide 24/7 emergency repair service during power outages?
Absolutely. Power failures don’t keep business hours, so neither do we. Our on-call electricians are available around the clock, stocked with common replacement parts and diagnostic tools. If your generator fails to start or shows an alarm code, call us any time; we’ll dispatch a technician to your Rogersville location, usually within two hours, to get you back up and running.
