"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."

"After putting in a request on Home Advisor, Mike responded very quickly. I advised him i wanted to install a transfer switch for a generator and he went through the steps of what would need to be done. He asked a few questions, asked for a picture of the junction box, and then gave me a very reasonable quote. The day of the install, he called to reconfirm our appointment. The install was quick and clean."

"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."

"Fast and super helpful. Gave me a proposal right away. Started work same week. If deviations were needed, was specific on what and why. Reasonable and fair pricing, and honest about their capabilities and areas of expertise. Professional team and went out the way to provide additional references for other concerns. I also appreciated the video Fabio took to show me the before and after, especially in areas I was unable to see."

Generator Install FAQs, answered by experts

In some situations, yes. Never try to put biofuel into any home generator without checking the specifics first. If a generator has the ability to run on diesel, it can also run pure biofuel (the clear kind made from seed oils, for example). But if you are using biofuel made from animal fats or vegetable oils, the generator will need significant modifications before it can handle a sludgier type of biofuel.

Yes, in some locations, it is required by the National Electric Code (NEC) to have a transfer switch installed for electrical emergencies. In addition to following electrical code, generator transfer switches ensure your home is fully protected during a power outage. By switching the power from the main breaker to the generator breaker, you can seamlessly operate your HVAC, lights, appliances, devices, and more during an emergency. 

It is safe to run a generator continuously, but you must follow safety protocols to ensure personal and home safety. Read the manufacturer’s instructions for specific recommendations, but the general recommendation is to turn generators off overnight or when you’re away from the house. Overworked generators can pose a fire hazard and if your generator is not in a well-ventilated area, running it continuously could lead to carbon monoxide poisoning.

A home that is 2,500 square feet will likely need a 20kW to 25kW generator. Consult your local generator installer to confirm the generator size needed to power your home before purchasing a new one. Be sure to consider how much power your necessary devices need to run.

These advanced generators use a key fob or a smartphone app to remotely start, which is ideal for getting power back on immediately without venturing outside. This feature is more common on whole home generators, but you may be able to find it on large portable generators, too.
