"It is weeks like this that make me so happy to have had Fitch Electric install a generator at my house. I had them install an EV Generator a few months ago and bit the bullet for the generator knowing this summer would be HOT and PGE would be shutting us down as usual. I cannot say enough great things about Fitch Electric https://fitchelectricinc.com/ They are professional, reasonably priced and are on-time and on budget. Thanks Lucas and your team at Fitch Electric 5 out of 5 star recommend ! I only said 4.5/5 on the value only because it's expensive regardless so this isnt a knock on Fitch just the whole generator world and PGE in general. I wish we didn't have to do this but in these times over the last several years WE KNOW that PGE will be shutting off power and this is just what we have to do. I love Fitch! Will use them again 100% in the future."

Customers say: True professional

"Armando is very professional, and I almost did not hire him because of a previous review he had on his feedback. Therefore, I received another quote from a higher rated area contractor who also stated prices were better. The other company failed to show up as scheduled, but arrived the following day and his prices were higher than Armandos quote. He did a fantastic job, price was fair, and was promt. He is trust worthy too, I had to run to my daughters college, 3.5 hours later, I arrived back at home..everything was perfectly installed, other items working in tip-top shape. He is respectful, and he is picks up after himself (and some of my extra dog hair too). Armando is my new, go to handyman. I am sure you will find him great.. He serves the Pleasanton area toom"

"I had my garden and bathroom remodel done. Albert and Samuel were professional, friendly, and a delight to work with. They're responsive and reliable. I also like the subcontractors whom they used on my project. They kept me informed of everything and I appreciate their excellent work."

"Did a great job, even corrected some code violations that were present when we moved in. Installed multiple 110v, 230v single phase, 230v 3 phase and 480v 3phase circuits, wired a paint booth, Tumbler unit, overhead crane systems, and even did some repairs on a complicated piece of machinery that wasn’t working. Great guys work hard no excuses. They get the job done plain and simple. I had used them twice because they were that reliable."

Generator Install questions, answered by experts

Yes. You can connect your home back-up battery to a generator with its designated charger. Be sure that the output of the generator matches the input requirements for the battery for best results.

Costs depend on generator type, labor, and additional wiring or transfer switch requirements.

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.

Whole-house generators can run continuously for extended periods, even for weeks at a time (around 400 to 500 hours), as long as they have a sufficient fuel supply. However, this type of extensive use will increase wear and tear and can shorten the generator's overall lifespan. During long periods of operation, it's important to check and refill the engine oil as needed, potentially as frequently as daily depending on the model. If your generator uses a fuel tank, ensure it is kept full to prevent unexpected shutdowns.

Yes, natural gas generators can work without electricity. Natural gas generators are a common type of backup or whole-house generator that operates when the electrical grid isn’t working. The trick is using a transfer switch (which usually needs to be installed with the generator) that safely switches the home electrical system from the power grid to generator power when needed.
