"Xavier diagnosed the situation and determined the trouble was the outdated main disconnect had a broken contact. He coordinated with CPS, the electricity supplier, and the company?s installer to remedy the problem quickly. He took time with me to explain everything and gave me a price quote in advance. He had been recommended to me by an elder in my church who had used him and said their price quote was a thousand dollars less than the other quote he got. Xavier is a great guy and now I consider him one of my friends. He is a honest old school electrician that believes in treating the customers with concern and care. I very seldom give reviews but this time I will rate their service as excellent."

"I had a fantastic experience with Voltsmith Electric. After hitting some confusion with a charger installation from another company, Mike came out, knew exactly what he was doing, and got our Level 2 EV charger installed and running at full power with no hassle. He was prompt, professional, meticulous with his work, and cleaned up everything before leaving. A completely smooth process from start to finish."

"I recently had a light fixture installed in my office and an electrical outlet relocated to a different area, and I couldn’t be happier with the results. The electrician was professional, punctual, and paid close attention to every detail. The installation was clean, the work was completed efficiently, and everything looks and functions perfectly. It’s clear they take pride in their craftsmanship and customer service. I highly recommend them to anyone looking for quality electrical work. Thank you for doing such an amazing job!"

"Lazaro Gonzales was my technician and he arrived at the exact time he was scheduled. He listened to what I wanted and offered better options. He explained what he was doing at every step and when he was done, he cleaned the area up better than it was when he arrived. I will hire Lazaro for all my electrical work from now on."

Generator Install FAQs, answered by experts

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.

Homeowners can often access federal tax credits, such as the Investment Tax Credit (ITC), which covers a percentage of installation costs. Many states and utilities offer additional rebates, grants, or performance-based incentives. These programs can significantly lower your upfront investment. Check the Database of State Incentives for Renewables and Efficiency (DSIRE) or contact your local energy office for current offers.

In many cases, yes. There are models called dual-fuel generators and fuel switches, but only between certain types of fuel. For example, with the right setup you can convert a generator from natural gas to propane. Some allow switching between diesel and gasoline. There are even tri-fuel generators available in some cases, which adds a large layer of security if you are worried about fuel availability in times of crisis. Always check your generator capabilities and manual instructions before trying to switch fuels. Some generators can use another fuel but may need a fuel conversion kit to prep them first.

Energy output depends on turbine size, average wind speed at your site, and system efficiency. A 5 kW turbine in a good wind location can generate 8,000 to 12,000 kilowatt-hours per year, which may cover a large portion of an average home’s needs. Accurate output estimates require a professional wind assessment and a review of your household’s energy usage patterns.

A 10,000-watt generator can run a small to mid-sized central AC unit (typically up to 3 tons or 36,000 BTU) along with a few other appliances. However, larger AC units or additional loads will require a bigger generator. Consult a local generator installer to ensure you add the correct size generator to your home.
