"Would not give basic quote, said would be done on site and installation done if price accepted. We expect they would have charged for the trip to estimate if price was rejected. Want quotes up front, thank you."

"Everyone from the start of working with this company was great. We had solar panels installed back in 2022 and the company then they went under federal control. I had called multiple companies, no one was willing to help except your home solar. We needed a permit to get the solar up and running which also meant the state inspection. Anita, Landon and all of the other employees that we encountered in this process made it a very easy process. I would recommend this company to anyone looking for solar or that needs to get panels they have up and running."

"Ashley made the process painless and easy. He communicated with me throughout the entire repair and even took the time to answer my questions as well. I’ve since added them for my annual maintenance to keep my generator working every time we need it."

"Embark is a company I would highly recommend without hesitation. The electricians arrived exactly on time, were very professional and completed project in a timely manner. They provided expert opinions and advice and were respectful and kind. The yard is now lighted with little stress from this home owner. They cleaned up their work area cleaned when done. Cost was as quoted. Would use Embark again if needed and recommend to friends."

Generator Install questions, answered by experts

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. 

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.

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.

To reduce AC startup power for a whole-house generator, install a soft start kit or hard start capacitor, which lowers the initial surge by gradually ramping up the compressor. Using a smart load manager can also help by staggering startup loads, preventing a system overload and future costly repairs.

A 10,000-watt generator can run a small to mid-sized central AC unit (typically up to 3 tons or 36,000 BTU) along with a few other appliances. However, larger AC units or additional loads will require a bigger generator. Consult a local generator installer to ensure you add the correct size generator to your home.
