"As usual their work was second to none. Outstanding job, took all of maybe 30 minutes. Was early and went right to work, located it and installed it PDQ. That’s why we have S&S on speed dial."

This generator was installed on the side of a house.  The window had to be replaced to allow for the generator to be placed in this location.  The window was made to not open per code.
We installed this 14kW generator to power the whole house.  We used load shed modules to be able to save the customer money by using a smaller generator than would have been needed if we didn't use the load shed modules.

"Eddie and his team did a phenomenal job installing the Tesla EV charger and a sub panel. I had some additional requirements for monitoring the power load to the charger which he researched into and took care. His price was very reasonable and the installation process was very smooth and efficient and he took care of the county inspection/ permit process without any issues. Highly recommended!!"

Great customer service, very knowledgeable, great work quality, competitive price and a really nice guy to work with. I ll call Saul and Three Brothers for all my electrical work in the future."

"On June 10, I had a company to install security equipment in my home. In doing so, the installer drilled through a wire and I did not have electricity in several outlets due to the damage. Since the company did not have an electrician on staff and was unable to refer me to anyone, I turned to Angie’s List for help in finding someone to correct the problem. I called Hands on Electric on June 11 and spoke to the owner, Kevin Williams. I explained my problem to Mr. Williams and he gave me a window of time in which he would be able to come out. Not only was he able to come out the same day that I called, but Mr. Williams was able to come much earlier than expected. Once he arrived he was able to trouble shoot and diagnose the problem. Mr. Williams was very, very friendly, professional and honest. He was able to answer my husband’s questions and explained what he was doing as he made the repairs. My husband was very happy about that and we were both impressed by the years of experience Mr. Williams had for his age. I have been looking for an electrician for a while now and have decided that I will be using Hands on Electric for all of my future projects. I was very pleased with the work that was done by Mr. Williams and will recommend him to my friends and family when they need of electrical services."

Generator Install questions, answered by experts

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.

Costs range from $500 to $2,500, depending on generator type and installation complexity.

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.

With proper maintenance, a whole-house generator can last between 20 and 40 years. The specific lifespan depends on how often and for how long the generator is used, and some models may have their life expectancy rated in hours of operation. To maximize its lifespan, expect to spend around $150 to $300 per year for annual maintenance checks from a qualified technician. During these checks, a technician will inspect the engine filter, starting mechanism, fuel, lubrication, and coolant levels. Consulting your installer and choosing a low-impact fuel like natural gas or diesel can also help ensure your generator lasts as long as possible.

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.
