"Preston and his crew were extremely busy with the fires in the area but still made time to get our project done. They did an outstanding job and did a very clean looking appearance on the home. Overall very pleased and will definitely look to use Eagle again for our future jobs."

"Thomas at Thunderbird Power is fantastic. He KNOWS his trade (a 3rd generation electrician)! Had 2 electricians last year try to fix some broken outlets, after 1.5 hours couldn't figure it out. Another electrician troubleshot it recently and his diagnostic tests ended up NOT being the issue. Thomas had them fixed in 30 minutes and didn't have separate charges for troubleshooting ontop of fixing, just took care of it. He was WAY cheaper than all the other electricians who quoted me in the area for that and replacing all our light fixtures + fixing other issues; I spoke to 6 different electrians in depth about our projects (8 including previous guys). He was the ONLY electrician who did not make a big deal about fans, nor talked small projects into huge ones and needing a second person to help him with all the work, etc. But he did the work in the same amount of time, alone. He was very professional, timely, detail-oriented, neat, and personable (dogs ADORED him). Will hire again!!!"

Job was well-planned by the estimator and the guys showed up well-informed as to the layout and modifications that we needed. Estimate was competitive with other companies that we approached. Work was performed efficiently and only delay was a result of a part on the system which was incorrectly positioned by original installer and he to be re-ordered. Jim & Rob were punctual, professional and hard-working and didn't inconvenience us at all.

Generator Install questions, answered by experts

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.

Costs range from $500 to $2,500, depending on generator type and installation complexity.

While natural gas generators are costly, they’re a great option for standby power due to the reliability of natural gas as a fuel source. Unlike other fuels, natural gas is delivered through underground pipes, making outages extremely rare and less likely to be affected by the elements. As long as the area isn’t prone to earthquakes, they offer an unlimited supply of natural gas that doesn’t degrade over time or require storage in tanks.

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.

To reduce AC startup power for a whole-house generator, install a soft start kit or hard start capacitor, which lowers the initial surge by gradually ramping up the compressor. Using a smart load manager can also help by staggering startup loads, preventing a system overload and future costly repairs.
