"John and his team were excellent. Of the electricians I got quotes from, John was the only one who noticed that some existing breakers in my panel didn’t match the panel’s manufacturer and shouldn’t have been there. His team arrived on time, was thorough, and focused on solving the problem I brought them, with no upselling or scare tactics. On top of that, the price for my EV charger install was excellent. Highly recommend, and would work with again in a heartbeat."

"All I can say is that Luis and Eric are amazing! They installed my JuiceBox 40 amp electric car charger in an hour and half! Super professional, very clean work, and I appreciated that they wore boot covers so my house wouldnâ t get dirty. Since they ran the wire through my basement they had to remove my ceiling panels, after the install they cleaned the floors and installed the ceiling panels back like it never happened! All in all amazing company, super fair price compared to other companies, and their communication with us was beyond amazing. Dominic came by yesterday for an estimate and it was installed in less than 24 hours! I cannot say anymore amazing things about this company and will be a repeat customer for my other projects. 5/5 STARS! â­ ï¸ â­ ï¸ â­ ï¸ â­ ï¸ â­ ï¸ Summary: 1. Very Fair price compared to competitors 2. Highly skilled and professional work 3. Free Estimate 4. Will not leave you in the dark and will communicate with you throughout the process and any questions you may have. 5. Accepts Credit Cards"

"I live in Queens and had Tom and Nick come by for a variety of electrical jobs, ranging from smaller items such as installing new switches throughout the house to rewiring of an electrical panel. They did an excellent job, and when my old electrical panel gave out, they were able to install a replacement pretty much on the spot."

Generator Install FAQs, answered by experts

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.

While standby generators provide essential backup power, they can fail when you need them most due to lack of maintenance, fuel supply issues, dead batteries, electrical problems, or improper installation. To avoid costly failures, professional installation and regular maintenance are crucial. Licensed technicians ensure safety, uphold warranty requirements, comply with regulations, and provide expert servicing.

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. 

Generators are usually sized by running watts and starting watts. Ideally, you’ll want a generator that can offer both the necessary running watts and starting watts for everything you need to power without going beyond 90% of its capacity. Calculate your home’s electrical load based on the breakers in your home or adding up the appliance and lighting needs of connected rooms.

No, you should never plug a generator directly into a wall outlet in your house. This practice is extremely dangerous, often illegal, and can cause "back-feeding," where power from the generator flows back into utility lines, creating a life-threatening hazard for utility workers. It can also damage your home's electrical system, including appliances like pumps and HVAC fans. If the main power is restored while the generator is connected, it can destroy the generator and cause an electrical fire. To safely connect a generator, you must use a professionally installed transfer switch or an interlocking kit, which prevents back-feeding by disconnecting your home from the utility grid before the generator provides power.
