"Project: Install Electrical Switches, Outlets. They were on time, professional and flexible. Also, discussed future projects - replacing a fixture in bathroom, and on their way out attached a smog detector the right way. I would definitely use this company again."

"Outstanding work! I needed some rewiring done, can lights installed in the kitchen, multiple outlets and switches changed out prior to selling my house. I also had the breaker box upgraded in the garage. They did all the work with just to visits. Some items had to be ordered. Great work! Fantastic clean up! Friendly and polite! Offered me a military discount without me even asking! If I ever need electrical work again these are the folks I'm going to and you should too!"

"We had an amazing experience with our electrician! He handled everything from installing our switches and outlets to completing the electrical wiring with incredible attention to detail. He also installed and wired our garage door motor flawlessly, and made sure everything, including the subpanel, was done properly and safely. What really stood out was his professionalism and work ethic. He kept everything clean and organized, which made a huge difference It’s not easy finding someone this reliable, skilled, and thorough. Highly recommend to anyone looking for quality electrical work done right the first time!"

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"

"Edgar is very detailed, respectful, professional with very good customer service! He showed up on time and completed the electric panel change sooner than expected! I have already referred him to my cross the street neighbor, Diane. Hopefully she will reach out soon for an estimate to change out her electrical panel too. Thank you ð ð"

Generator Install questions, answered by experts

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.

DIY is possible for basic setups. Professional installation ensures safe and proper electrical connections.

While diesel is relatively stable, it won’t last nearly as long as propane and you may have to replace it if it sits unused for too long. Diesel can sometimes struggle to work efficiently or start engines during especially cold weather, so it’s not the best choice for every climate. Compared to fuels like propane and natural gas, diesel generators tend to be noisier and create more exhaust, which isn’t always ideal for home use.

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.

Carbon monoxide emissions aren’t only dangerous to human life, but they also harm our planet. While natural gas generators emit lower levels of CO than other fuel sources, there are still ways to reduce emission levels. For example, shop around for an eco-friendly generator that complies with current emission standards. Also, make sure your generator is serviced regularly to avoid CO buildup.
