Customers say: True professional

"Sean did a good job and worked efficiently. He was able to do all the tasks we requested. I'm satisfied with his work. He did our job on a Saturday and I was very happy he went out of his way to work us into the schedule. I would hire him again, no question. The only disappointment was that he didn't clean up afterward as well as I thought would be done. For example, where metal siding had to be cut to install new fixtures, there were still pieces of the sharp metal lying around (larger than an inch square)."

"Brandon was great. I called him, he was available, and my job was finished three hours later. He communicated well, gave me a clear estimate, and showed up exactly when he said he would. He had to dig a trench in my flower bed mulch to bury a wire, and he put all the mulch back carefully- you couldnâ t even see anything had been done. I will use him in the future whenever I need an electrician."

Generator Install FAQs, answered by experts

Here’s what you can run with different wattages and types of generators:

Portable generator:

  • 2,000 watts can handle a large appliance like a freezer or refrigerator, plus a few smaller items like phones or computer chargers. 

  • 4,000 watts will keep two large appliances operating and a few smaller devices.

  • 8,000 watts should power most essential appliances and other devices, including a sump pump, well pump, or your dishwasher.

Partial to whole-house generator:

  • 20,000 watts and above will make it seem like your home’s power is still on.

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.

To power a central air system during a power outage, the whole-house generator will need to be at least 5,000 watts, and this number will significantly increase for larger units. Check the specific wattage requirements of your AC unit to choose the right generator size. Consider consulting a generator installer to ensure your whole-house generator meets your electrical load needs.

Yes, installing a generator usually increases your property value because buyers are getting the added peace of mind knowing they’ll be able to maintain power through blackouts. In most cases, you should see close to a 100% return on investment (ROI). Keep in mind that home generators usually need a permanent foundation, and installing a concrete slab will likely raise your property taxes slightly.

Whole-house generators need to be installed on level ground several feet away from walls and other objects. Because they tap into the electrical system directly, they usually need to be close to your home electrical panel for a transfer switch installation. It also helps with installation if they are near to a gas line or propane tank installation.
