"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

While the rating will tell you how many watts the refrigerator needs at the peak of its cycle, it requires additional wattage to start. At the bare minimum, you’ll need a 1,500-watt generator to get the fridge up and running after a blackout. A 2,000-watt generator should be sufficient for most home refrigerators.

The cost to install a whole-house generator averages $5,200, with a typical price range of $1,500 to $8,900. However, total costs can vary from $400 for a small portable unit to over $18,000 for a large-capacity system. The most significant cost factor is the generator's size and capacity, but other variables include the brand, fuel type, and labor for assembly and installation.

Generator costs can be broken down by type:

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

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

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

To avoid paying for more power than you need, consider hiring an electrician to calculate the electrical load for your essential appliances. It is also recommended to get at least three quotes to find the best deal for your specific needs and budget.

An undersized whole-house generator has the potential to overheat and shut down when you try to run a central AC system. This scenario can not only damage the whole-house generator, but can also trip your home’s breakers or cause electrical damage. To avoid this situation, hire a local generator installer to correctly size your whole-house generator.

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.

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.
