"Frank responded quickly to my inquiry, and was able to schedule me in the very next day. He showed up on time and did a thorough investigation of my electric panel and house layout before coming up a clever plan with minimal cut in my dry wall. He explained what needed to be done and patiently answered all my questions . He completed the work within three hours, and was kind enough to wait for me testing my treadmill using the new outlet. He is very professional and honest about his work, and I would use him again for future needs."

"In general, it went well. Everyone from Huft was very professional. The salesperson could not tell me the brand of water heater that would be installed. I had responded to ad on Angie's list. I should have paid attention to this. In the past, sales reps from other companies could tell me the brand name of the product, and if it qualified for a rebate. The product that was installed is an excellent product, but doesn't qualify for a rebate. The service personnel were all very polite and professional. What I would have done differently is pursued finding out the brand name of the product before it was installed and found out if it qualified for any SMUD rebates before making the purchase. In general, I would give Huft an excellent rating for service. They came back two days later when the water heater wasn't producing hot water, and installed new fuses. The technician was very professional and courteous. As a consumer, remember to jot down as many questions as possible before you meet with the contractor."

"Our house is over 30 years old and the electrical panel was in questionable state after various contractors over the years had accessed it for their projects. For safety and security reasons, we had Rooster Electric upgrade the electrical panel. The electrician needed to cut the house siding to install the new panel and did so expertly, providing new trim and caulking. The job looks great and we feel safer now that the panel is up to specs. Thank you, Rooster Electric, for walking us through the project and doing excellent work. Weâ re so tired of contractors taking the quick and easy route to get their job done rather than providing good, respectable customer service. Youâ ll get our recommendation whenever someone asks if we know a good and trustworthy electrical company. L&N in Fair Oaks"

Generator Install questions, answered by experts

You can expect a diesel generator to last for up to 30,000 hours of use, which works out to 20 to 25 years with the proper maintenance, of course. That depends on how much you use it, so a diesel generator used for emergencies a couple of times a year will last a lot longer than a generator that takes over for a faulty electrical grid every month for a day or two. 

If your home already has a grinder pump and you’re still noticing issues (like frequently clogged toilets and sinks), it could be time to upgrade your grinder pump. Start by checking your existing horsepower. If there are four or fewer people living in your home, using a 1/2-horsepower grinder pump should be sufficient. Larger households should consider investing in a 1-horsepower grinder pump to maximize wastewater removal efforts.

You may need a permit for a portable generator if you’ll be installing a transfer switch for your primary residence or similar work. Otherwise, a permit for other uses may not be necessary. Check your local building codes or ask a local generator installer for more information about your local regulations.

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.

Setting up utilities on a vacant property usually takes at least a few months, or between 6 weeks to 16 weeks. This process requires working with the local planning and zoning department, hiring a building contractor or engineer to design the utility layout, securing permits, laying the lines, and connecting the utilities.
