"Sergio did a fantastic job! Very happy with the clean install of my tier 2 charger and he added a plug down below my panel. Would recommend for any sort of EV charging installs! Clear communicator, showed up when he said he would and his services were well-priced!"

"I worked with Obed on this project. He was friendly, responsive, and very professional. He helped me install a new circuit and outlet for an EV charger, along with some other light electrical work. His price was fair and competitive with other bids I received, and the work was completed timely and competently. I will reach out to him again for any electrical needs."

"B&C Electric did a great job. Robert Burns came to my house after another electrician from another company installed a Tesla charger. For the next 4 weeks we had trouble with different areas of our house losing power. I called this initial electrician back to fix the problem. He came and did some work but the power outages continued. That's when I said enough is enough and called Robert at B&C electric. He came and did a thorough evaluation of my sub panel. He found that the breaker switch installed by the other company was not only cheap but not wired correctly. Robert installed a new breaker switch and I have not had any trouble since. Robert explained everything to me and showed me what he was doing. The best electrician I have used, hands down. I will use him again!"

"Having electrical issues to the point of calling SDG&E who sent a tech out immediately. Verdict: SDG&E was not the problem; the problem was in our panel. Appointment set, Jeremiah came right on time, made the diagnosis, gave us the options, and made the repairs within the hour. Jeremiah gave great information on the problem and the causes of the issue. Will use Mister Sparky in the future for any electrical issue."

"They installed a 50 amp plug in my garage to connect an EV charger. I was afraid that the installation may require a panel upgrade. But he made it work without the upgrade. The price was good and the work was done quickly. Great job. Would hire them again."

Generator Install questions, answered by experts

Natural gas and electricity rates vary significantly based on location, and pricing can change over time, too. It’s possible that in locations where natural gas is particularly inexpensive, it will cost less than grid-based electricity will. However, you should also factor in the generator’s initial costs and maintenance needs, as well as its noise level and if it can comfortably power all your home appliances.

Potential benefits of using a natural gas generator include reducing your carbon footprint, lower likelihood of carbon monoxide exposure, budget-friendly operating costs, and low-maintenance, continuous fuel supply. Some possible drawbacks, though, include higher initial installation costs, dependency on a natural gas supply, and installation complexity. Keep in mind that pros and cons will vary based on the type and brand of natural gas generator. 

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.

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.

To determine the right size generator for your house, you should calculate the total wattage of the appliances and devices you want to power during an outage. List all essential items, note their start-up wattages, and add them together.

Here are some typical wattage requirements for common appliances:

  • Refrigerator: 600 watts

  • Large dehumidifier: 700 watts

  • Large window air conditioner: 1,400 watts

  • Water heater: 3,000 to 4,500 watts

  • Electric furnace: 5,000 to 25,000 watts

A 7,500-watt generator might be sufficient for essentials like a refrigerator, freezer, well pump, and lighting circuits. However, for high-demand items like a water heater or furnace, a whole-home generator is a better choice. A portable generator may be enough if you only need to power a few critical items.

While home square footage can offer a rough estimate, it is not always a reliable indicator. For reference, here are some typical generator sizes based on square footage:

  • 1,000 sq ft: 6–9 kW

  • 1,500 sq ft: 7–10 kW

  • 2,000 sq ft: 10–14 kW

  • 2,500 sq ft: 12–16 kW

  • 3,000 sq ft: 16–20 kW+

For the most accurate sizing, consult a professional who can calculate your home's peak and average power consumption and recommend the optimal generator.
