"George Leach is top of the line contractor/electrician and I give my highest recommendation. I contracted George to install an EV charger for my new Cadillac EV, and I wanted top of the line. I wanted to make sure that my charger was going to handle the output that I wanted for the high amp Enphase charger that I wanted to install. I queried five contractors and only George was responsive, had follow up, and actually did his own background to make sure that what I wanted to do was going to work. He did the extra work to investigate my panel to ensure that my infrastructure could accommodate the extra load. As a home owner, I could tell immediately I was in good hands. I had cheaper options--but I dismissed those out of hand because of poor attitudes, service, follow-up, and shortcut takers. George Leach is none of those things. Not only does George take the extra time to think through his work, when he meets an obstacle, he takes the time to work through it and does the quality job. We have zero worry with regard to the quality of the install of the panel and the charger. Can't recommend George any more highly. I wish I could, cuz he's also a sweetheart. Hiring George was a good decision. Thank you, George!!!!"

"Anthony did a great job and was very thorough and professional. He did a great job in explaining how my antenna system worked and said he was just a phone call away if I had any questions. I would hire him again for any other projects I may have. Thank you for being so thoughtful and professional."

Generator Install questions, answered by experts

While standby generators provide essential backup power, they can fail when you need them most due to lack of maintenance, fuel supply issues, dead batteries, electrical problems, or improper installation. To avoid costly failures, professional installation and regular maintenance are crucial. Licensed technicians ensure safety, uphold warranty requirements, comply with regulations, and provide expert servicing.

Sizing a generator is a careful process that requires calculating the electrical load of your entire house. You have to take into account every device you want to use and their wattage requirements, plus the wattage needed to start them, and look for a generator that can safely run all that at around 80% capacity.

In more practical terms, a small home can run on a 10,000-watt generator (and if you only want to power a few key appliances, much less than that). A mid-sized home may need something between 15,000 and 22,000 watts. Larger homes require 25,000 watts or more. 

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.

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.

It’s usually better to repair your generator if it isn’t working properly, as it will typically be much more affordable and should yield similar results. Generator repairs cost around $300 on average, while installing a new whole-house generator costs around $5,000 on average. The only exception is if you know your generator is reaching the end of its useful life, usually between 30 and 40 years. If you have an older generator, you could face multiple repairs in the coming years, which might mean that a full replacement will be more cost-effective over time.
