"I had used Worry Free Electric in the past and had very good service. I called James Costello again for some outlet relocations, new outlets, and new light fixtures installation/replacement. I was supplying these new light fixtures. I told James what I wanted to achieve, and where I wanted the new outlets and ceiling lighting fixtures located. He made some recommendations and suggestions, did exactly what I wanted and beyond with the addition of some three way switches for the lighting circuits. The whole experience was above my expectations. James Costello will be my first call for any future licensed Electrician project!"

"I am more than pleased with the service I received from this company. Nathan is by far a caring human being. When the big companies couldnâ t help me out, he was there to service My Generac and he has been there ever since whenever I need him. Iâ ve been using this company for at least the last four years. And will continue to gladly call him when needed."

He installed 6 can lights in our previous dark kitchen and anew dining room light. He also put a led light in our previous dark basement laundry room. Fixed safety hazards in our attic. I would highly recommend his company. We are so happy we found him."

Generator Install FAQs, answered by experts

A portable generator can supply power to selected appliances and circuits in a home, but it's generally not designed to handle the entire household's electrical needs simultaneously. Portable generators have limited wattage capacity, so they are only designed to power essential devices and electronics temporarily until local power is restored. If your power needs outweigh the capabilities of a portable generator, consider installing a whole-home generator instead.

While diesel is relatively stable, it won’t last nearly as long as propane and you may have to replace it if it sits unused for too long. Diesel can sometimes struggle to work efficiently or start engines during especially cold weather, so it’s not the best choice for every climate. Compared to fuels like propane and natural gas, diesel generators tend to be noisier and create more exhaust, which isn’t always ideal for home use.

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.

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. 

You can expect a diesel generator to last for up to 30,000 hours of use, which works out to 20 to 25 years with the proper maintenance, of course. That depends on how much you use it, so a diesel generator used for emergencies a couple of times a year will last a lot longer than a generator that takes over for a faulty electrical grid every month for a day or two.
