"Outstanding service. I originally needed an electrician to determine why I lost power to ½ my house. What Jody uncovered was a defective circuit breaker and my main switches overheating and in the process of melting down. He was able to change out the panel and install new breakers immediately. I’m grateful for the prompt response by Gene and the professionalism of Jody and Brian."

"Ron Ethridge has been our Electrician of chose for the past three years. I started out using Ron to service my generator after the warranty lapsed. Heâ  s provided that big company expertise with that small organization connection. Since that time Ron and his team have provided electrical services for our entire home. I feel comfortable leaving Ron in our home while weâ  re away which is a huge feat for me particularly. Iâ  m grateful for the service that Ron and his team continues to provide to our family."

"Patrick, who supervised the installation of a generator which I had, also worked up the initial recommendations and estimate. This generator was used, but that did not deter Patrick from coming up with a plan. Other contractors sent estimators who were more sales people than experienced generator contractors. Only Ritzau made the recommendation to replace the old fashioned transfer switch which came with the unit with an up to date digital transfer switch. This

"We would definitely contact Mr. Williams for more household projects. He installed a gas cooktop with a downdraft for us. During the install, he discovered that the vent pipe being used by the old downdraft fan was too small. To ensure that we would have a working cooktop that evening, Mr. Williams went to the hardware store for new parts. The price of the project was very reasonable. He also followed COVID-19 safety protocols (mask, gloves, social distancing, staying within the worksite) for the entire project."

Generator Install questions, answered by experts

Energy output depends on turbine size, average wind speed at your site, and system efficiency. A 5 kW turbine in a good wind location can generate 8,000 to 12,000 kilowatt-hours per year, which may cover a large portion of an average home’s needs. Accurate output estimates require a professional wind assessment and a review of your household’s energy usage patterns.

No, you should never plug a generator directly into a wall outlet in your house. This practice is extremely dangerous, often illegal, and can cause "back-feeding," where power from the generator flows back into utility lines, creating a life-threatening hazard for utility workers. It can also damage your home's electrical system, including appliances like pumps and HVAC fans. If the main power is restored while the generator is connected, it can destroy the generator and cause an electrical fire. To safely connect a generator, you must use a professionally installed transfer switch or an interlocking kit, which prevents back-feeding by disconnecting your home from the utility grid before the generator provides power.

In many cases, yes. There are models called dual-fuel generators and fuel switches, but only between certain types of fuel. For example, with the right setup you can convert a generator from natural gas to propane. Some allow switching between diesel and gasoline. There are even tri-fuel generators available in some cases, which adds a large layer of security if you are worried about fuel availability in times of crisis. Always check your generator capabilities and manual instructions before trying to switch fuels. Some generators can use another fuel but may need a fuel conversion kit to prep them first.

In some situations, yes. Never try to put biofuel into any home generator without checking the specifics first. If a generator has the ability to run on diesel, it can also run pure biofuel (the clear kind made from seed oils, for example). But if you are using biofuel made from animal fats or vegetable oils, the generator will need significant modifications before it can handle a sludgier type of biofuel.

An undersized whole-house generator has the potential to overheat and shut down when you try to run a central AC system. This scenario can not only damage the whole-house generator, but can also trip your home’s breakers or cause electrical damage. To avoid this situation, hire a local generator installer to correctly size your whole-house generator.
