"Three years after I bought the generator, our power was out on a Sunday morning and the generator did not start. They were out in an hour and had it working. What more could you ask for?"

"We wanted to try a local contractor and came across Evergreen by chance.  It was an excellent experience.  Thad was knowledgeable and professional and easy to work with.  The crew was exactly the same.  Nice, respectful, competent.  The worked around my crazy schedule as we had other improvements going on.  They had a slight delay in getting the generator as there was a back order, but called and let us know and we worked around it.  Laurie in the office was equally good and kept us in communication on details or things to do and schedule etc.  I could not be more happy with the experience on such a big purchase.  They were always accommodating and helpful.  The Generator and switch were high quality and I think the price was fair.  They even did some easy side things for us for no charge.  We will definitely use them again soon to install an attic fan."

"The job went great! Livengood Electric went over and above my expectations for this project. This wasn’t the easiest project out there on sure but with Jake’s expertise he was able to make short work of the project. We have a new service panel do you provide us years ofTrouble free electrical service, and a new generator but when the power goes out! We couldn’t be happier! Thanks again Jake!"

Generator Install questions, answered by experts

The amount of time a standby generator can run continuously is around 3,000 hours on average. However, standby generators can generally run indefinitely as long as they have a continuous fuel supply. Generators hooked up to a home’s natural gas supply are the best option for extended usage, as these won’t rely on a finite fuel supply based on how much you have in storage. Generators running on liquid propane or diesel won’t last as long, as these require fuel storage and regular refueling to stay running.

The average cost to install a home generator is $5,200, but total costs can range from $500 to $18,000 or more. The final price depends on several factors, including the generator's size, type, brand, fuel source, and the cost of labor and assembly. The generator's size is the most significant cost factor, as units that can power larger homes with higher energy demands cost more.

Cost breakdowns by generator type are typically as follows:

  • Portable or Emergency Backup Generators (1kW–7.5kW): $500–$2,000

  • Partial-Home Generators (9kW–20kW): $2,000–$6,500

  • Whole-House Generators (22kW–48kW): $5,000–$18,000

To ensure you get the right size unit for your needs without overpaying, consider hiring an electrician to calculate the electrical load of your essential appliances. It is also recommended to get at least three quotes from qualified installers to find the best fit for your budget.

Generators are safe to use as long as they are installed and operated correctly according to the manufacturer's recommendations. The most critical safety tips are to never use a portable or fuel-powered generator inside an enclosed space due to the risk of lethal carbon monoxide poisoning; always operate it outdoors where fumes can dissipate away from your home. Additionally, never attempt to connect a generator to your home’s electrical panel yourself—hire a professional to ensure the setup meets safety standards. Finally, avoid overloading the generator by not connecting more appliances than it is rated for, as this can damage your equipment or cause a fire.

A portable generator can supply power to selected appliances and circuits in a home, but it's generally not designed to handle the entire household's electrical needs simultaneously. Portable generators have limited wattage capacity, so they are only designed to power essential devices and electronics temporarily until local power is restored. If your power needs outweigh the capabilities of a portable generator, consider installing a whole-home generator instead.

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.
