"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."

"Scott provided the lowest estimate of the three I got. He was able to schedule the job in less than a week and the job was done well and quickly as scheduled. No issues since the job was completed about a week ago. I would call him first for any other electrical work I may have in the future."

Generator Install questions, answered by experts

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.

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

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.

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. 

Most homeowners won't be able to claim a home generator as a tax write-off. However, a whole-house generator may be tax-deductible in certain situations depending on its purpose. For instance, if it's needed to power essential medical equipment, it may qualify as a medical expense deduction. Also, in some cases, businesses can deduct a generator as a business expense if it supports operations. Always consult a tax professional to determine eligibility based on your specific circumstances and the applicable IRS regulations.
