FAQs
What makes a system “critical,” and why is a standby generator important for it?
A critical system is any electrical load that must remain powered to protect life, safety, data, or major financial assets—such as medical equipment, communications networks, security systems, refrigeration, and key production lines. In Dandridge, severe weather and an aging grid can cause outages that last hours or even days. A properly sized standby generator automatically restores power within seconds, eliminating downtime, preventing product loss, and ensuring occupant safety.
Which generator brands and fuel types do you install or service in Dandridge?
We are factory-authorized dealers for Generac, Kohler, and Cummins residential and light-commercial units. Our technicians also service most major brands. Fuel options include natural gas, propane (LP), and diesel. We help you choose the best fuel based on local availability, run-time requirements, and environmental considerations.
How do you determine the correct generator size for my home or business?
Sizing starts with an on-site load analysis. We catalog every circuit you want to protect, measure starting and running amperage, and factor in voltage drop, motor inrush, and future expansion. Using industry software and NEC guidelines, we calculate total kilowatt (kW) demand and recommend a generator with at least a 20 % safety margin to handle peak loads without over-fueling or under-loading the engine.
Do you take care of permits, utility coordination, and inspections in Jefferson County?
Yes. We prepare and submit all required electrical and gas permits, coordinate with AUB or your local utility for meter pulls and interconnection approval, and schedule final inspections with Jefferson County building officials. This turnkey approach saves you time and ensures the installation meets NEC, NFPA 70, and local code requirements.
What maintenance services do you provide, and how often are they needed?
Our preventative maintenance packages include semi-annual or annual visits that cover oil and filter changes, coolant and battery checks, load-bank testing, controller firmware updates, and full diagnostic reporting. Regular maintenance is essential for warranty compliance and maximizes reliability when the generator is called upon during an outage.
What is your emergency response time if my generator fails during a power outage?
We offer 24/7 emergency dispatch for customers in the Dandridge area. Typical on-site response is within 2–4 hours, even during widespread weather events. Our service trucks carry common parts, allowing us to resolve most issues in a single visit so your critical systems are back online as quickly as possible.
