"Excellent work as always - this is our third time using Antonio and they always do a great job and clean up! We had a new panel installed with a switch for a new generator that I bought. They also ran a new circuit for my microwave which used to trip the breaker all the time. THANK YOU!"

"Ossie and his team did a fantastic job. He added a transfer switch to my main electrical box for a generator hook up. Ossie was very professional, responded in a timely fashion and gave me a fair price. I would highly recommend Ossie Electric for any projects you have."

"Joe Rinaldi and his team are top notch electricians and I highly recommend them for any residential service. I requested the services of AM/PM Electric on two occasions; One service request was for a non working outlet in the master bathroom and the second request was to install three new electrical lines in the garage of my home. Joe and his team did extraordinary work on both jobs. My dedicated 120V and 240V lines in the garage were professionally installed and routed through conduit. The end result was a very clean run with everything installed by code. There was a small mishap where the circuit breaker I requested was out of stock however Joe personally corrected the problem as soon as he could. In my experience, AM/PM is one of the best electrical contractors in Westchester and I highly recommend their service. My interactions with Joe proves to me that he truly cares for his customers and the quality of his work. He worked to make sure that I was fully satisfied. I can't ask for a better contractor in Westchester County, NY. This is an honest review by a new homeowner in Cortlandt Manor, NY."

"We hired Conte to install wiring and overhead light/fan fixtures for 3 bedrooms, and to install wiring and lighting for a large attic. We first got an appraisal, and the office staff had already tentatively scheduled a work date, which worked out well. I was at work during the process, but the crew of 2 electricians were able to let themselves in and perform the work. I came later to check it out and they did a terrific job. Frankly, if I didn't know I hired them, I would have never known they were there. Perfect work, everything cleaned up, and now we can see in the attic. They installed an illuminated switch in the hallway below attic so that we can turn on the lights from below and see (via the illuminated switch) if the lights are on or off. Definitely would hire them again."

Generator Install questions, answered by experts

If you have a transfer switch properly installed, the generator and main electrical power cannot feed the system at the same time. However, you should still shut off the power at your main circuit breaker panel before activating the generator. If you do that, you’ll simply need to shut off the generator and reset your circuit breaker once the local power comes back on.

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.

Generators are safe to use as long as they are installed and operated correctly according to the manufacturer's recommendations. The most critical safety tips are to never use a portable or fuel-powered generator inside an enclosed space due to the risk of lethal carbon monoxide poisoning; always operate it outdoors where fumes can dissipate away from your home. Additionally, never attempt to connect a generator to your home’s electrical panel yourself—hire a professional to ensure the setup meets safety standards. Finally, avoid overloading the generator by not connecting more appliances than it is rated for, as this can damage your equipment or cause a fire.

With proper maintenance, a whole-house generator can last between 20 and 40 years. The specific lifespan depends on how often and for how long the generator is used, and some models may have their life expectancy rated in hours of operation. To maximize its lifespan, expect to spend around $150 to $300 per year for annual maintenance checks from a qualified technician. During these checks, a technician will inspect the engine filter, starting mechanism, fuel, lubrication, and coolant levels. Consulting your installer and choosing a low-impact fuel like natural gas or diesel can also help ensure your generator lasts as long as possible.

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.
