Our Big Frog, James Crofutt, after having worked for the larger electrical companies, decided the industry needed a change so, Big Frog Electric jumped in with a splash in 2011. His 21 years of experience in the field backed with numerous certifications and licenses makes our know-how hard to beat. Having spent these years directly interfacing with customers, James understands that customers priorities include personable service, fast response times, the ability to trust that the job is being done right, and professionalism. At Big Frog Electric we do not have commissioned salesman, just electricians that have your safety as their #1 priority and not their pockets! We fill a void in the disappearing art of craftsmanship, integrity and character in the electrical contracting business. Our Frogs are fully dedicated to the electrical trade, its research, industry knowledge and are actively on the edge of new technologies. Each Tadpole (new hires) we recruit displays optimal craftsmanship, knowledge, courtesy and professionalism with each project - from inspection to conception to completion. You can have peace of mind with Big Frog Electric on the job. Big Frog Electric is a family-owned, owner-operated, electrical service company that appreciate the communities we service and gives back where we can. One way that Big Frog Electric gives back is by offering a special discount to all of our public school teachers, veterans, seniors and first responders. Award winning .

"Outstanding service ! I supposedly had a plumber coming and called Frog Electric on short notice to tie in the project and do some other wiring including running unerground service to my camper. The owner ,James ,and his crew Tom and David and later two other employees whose names I did not catch did a great job .Thank you all."

"I recently had an electrical inspection done by TE Certified Electrical, Plumbing, Heating & Cooling, and I couldn’t be more impressed. From the moment the technician arrived, the experience was professional, thorough, and reassuring. They took the time to explain everything they found in a way that was easy to understand, and I felt confident I was in good hands. What stood out most was their attention to detail—they didn’t just check the basics, they inspected the entire system to ensure my home was safe and up to code. No high-pressure sales, just honest advice and helpful recommendations. I’ll absolutely be using TE Certified again and would highly recommend them to anyone looking for top-tier electrical service."

"The latest visit diagnosed a failed ignition valve which needed to be ordered and replaced. They arrived promptly, assessed, diagnosed and ordered the parts immediately. It only took a few days for the parts to arrive and they were able to schedule me in for the service call. The first technician was able to maintain the ignition valve until the new part was available, which was directly responsible for heating my home. The second technician installed the part and was able to assist me in some technical updates on the app and digital thermostats. I learned so much from Michael and appreciated his knowledge and patience. He also fixed a safety issue on the second level and adjusted the air flow for the system. The system sounds so much quieter. It was a warranty issue with no cost."

Generator Install questions, answered by experts

Generators are usually sized by running watts and starting watts. Ideally, you’ll want a generator that can offer both the necessary running watts and starting watts for everything you need to power without going beyond 90% of its capacity. Calculate your home’s electrical load based on the breakers in your home or adding up the appliance and lighting needs of connected rooms.

Whole-house generators need to be installed on level ground several feet away from walls and other objects. Because they tap into the electrical system directly, they usually need to be close to your home electrical panel for a transfer switch installation. It also helps with installation if they are near to a gas line or propane tank installation.

Generally, you’ll want to keep between 60 and 70 feet between the generator and the transfer switch. There are a few reasons for this, including:

  • The distance reduces the noise coming from the generator into your home.

  • It increases efficiency because you won’t have a voltage drop from this short of a distance.

  • Prevents carbon monoxide poisoning: keep at least 15 feet between your generator and an open window. 

As long as they have enough fuel, whole-house generators can run for weeks at a time (400 to 500 hours) without suffering too much wear and tear. However, this type of extensive use isn’t ideal if you want to extend the life of your generator.

Two important points. First, some generators may need you to periodically check oil levels every day or so and refill as necessary for safe operation. Second, if your generator uses a fuel tank, keep it regularly full so it doesn’t suddenly shut off. Many backup generators can run through a full tank in a day when they are powering large portions of a home.

Many services include assembling the unit and securing it in the window. Confirm with your provider.
