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

A 1,500 square foot home will likely need a 15kW to 20kW generator. When deciding on whole-house generator size, add up the total wattage of the devices that you’d like to continue running during a power outage. That way, you can ensure you purchase a generator that can power your necessary appliances or medical equipment during an electrical emergency.

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. 

A portable generator can supply power to selected appliances and circuits in a home, but it's generally not designed to handle the entire household's electrical needs simultaneously. Portable generators have limited wattage capacity, so they are only designed to power essential devices and electronics temporarily until local power is restored. If your power needs outweigh the capabilities of a portable generator, consider installing a whole-home generator instead.

Generally, you’ll want to keep between 60 and 70 feet between the generator and the transfer switch. There are a few reasons for this, including:

  • The distance reduces the noise coming from the generator into your home.

  • It increases efficiency because you won’t have a voltage drop from this short of a distance.

  • Prevents carbon monoxide poisoning: keep at least 15 feet between your generator and an open window. 

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.
