"He is extremely attentive to your needs . What he says will happen , does! He keeps all appointments and thoroughly explains what he plans to do. He is one of the most reliable, ethical , conscience businessman I have ever dealt with. I have recommended him to friends . He actually went out of his way to help Ill friends deal with their generator problems even though he had not installed it. He made arrangements for someone to fix the generator when he was not able. Highly recommended !"

"Tylor was quick to respond to my inquiry and very accommodating to fix my problem as soon as he could. His expertise was shown as he diagnosed the possible issue over the phone and he had it fixed in no time once he arrived. He even fixed a lesser issue for no extra charge. I found his rates exceptional, and he will always be my first call for any of my future electrical issues."

"This was the second job I hired ESC for, the first was a hot tub hookup, and this one wasn't a simple one: install a generator hook up that bypassed only some of my critical circuits to the generator, while leaving the rest of the house on the grid. This required a pretty complex panel with multiple switches and breakers. He did a neat and tidy job and was in and out in about 3 hours! He does the work alone, showed up on time, does a timely, high-quality job and is friendly and considerate to my needs, as a COVID-19 Locked down, WFH customer and he also worked with me on the quote, to get the number where I needed it to be. Kevin *IS* his business, meaning he does the jobs by day and the and invoicing and estimates by night. As he told me: he wants the work but, working on jobs all day doesn't leave much time for getting back to quote request and questions. I think he could do a better job of communicating that up front (why he took a slight ding on my customer service rating) but ultimately I was really glad I waited him out. In short, I'd definitely recommend ESC for your household electrical work, just be patient with his getting back to you. I will likely hire him again."

"Highly recommend!! Peter was very professional and easy to work with. Came when he said he would and finished the job on time. He also returned after the installation was complete to make certain furnace was running well and to install a new CO2 monitor when he noticed mine was outdated."

"I had a small electrical fire on a Saturday from out dated cloth wire. These guys showed up got it fixed to where my house was safe and came back on a Sunday to get it 100 percent done rewiring my out door lights for my front door. Amazing professional work. They came back a little later and re wiring my entire house for me new panel new wires handled the permit. I can’t say enough about their work and professionalism I have no issue leaving them a key to work while I’m not home. Again amazing quality work"

Generator Install FAQs, answered by experts

Yes, in most municipalities, you will need a permit to install a permanent home generator, including emergency backup, partial-home, and whole-home models. Because these installations involve significant alterations to your home's electrical system and produce exhaust fumes, local governments often require a permit or inspection for safety purposes. A generator permit typically costs between $50 and $250, depending on your location. Your electrician or certified installer can usually handle the permitting process for you, but you will be responsible for the cost. It's a good practice to confirm with your installer that they will pull all necessary permits before work begins.

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.

Setting up utilities on a vacant property usually takes at least a few months, or between 6 weeks to 16 weeks. This process requires working with the local planning and zoning department, hiring a building contractor or engineer to design the utility layout, securing permits, laying the lines, and connecting the utilities.

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. 

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