"Highly recommend contacting them for electrical work! Responded quickly to come and give a quote for a generator hook up. Explained everything thoroughly and gave helpful suggestions as this was my first experience getting a generator to power the house. Very reasonable pricing. From first contact to getting it installed in under 2 weeks. Very happy!!"

"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."

"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 questions, answered by experts

The amount of time a standby generator can run continuously is around 3,000 hours on average. However, standby generators can generally run indefinitely as long as they have a continuous fuel supply. Generators hooked up to a home’s natural gas supply are the best option for extended usage, as these won’t rely on a finite fuel supply based on how much you have in storage. Generators running on liquid propane or diesel won’t last as long, as these require fuel storage and regular refueling to stay running.

As a safety measure, you should always turn off the main breaker while operating your generator’s backup breaker. In addition, you should also switch off all appliance breakers so you don't have a power surge when the main breaker turns back on. And finally, turning off the main breaker prevents back-feeding, which endangers utility workers with the risk of electrocution. Back-feeding could also destroy the electrical circuits of your neighbors if they use the same power network.

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.

Carbon monoxide emissions aren’t only dangerous to human life, but they also harm our planet. While natural gas generators emit lower levels of CO than other fuel sources, there are still ways to reduce emission levels. For example, shop around for an eco-friendly generator that complies with current emission standards. Also, make sure your generator is serviced regularly to avoid CO buildup. 

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.
