"J accommodated me by giving me an appointment right away. I had the use of only half of my outlets following an electric outage in Brockton on 7/11. When J left all of my outlets were working. He followed up the next day when there was a slight problem with a two of the outlets after he left. I can say that all of the outlets are in good working order. J is a pleasant and patient electrician who arrived on time and explained the problems I was having as well as what needed to be done to fix the problem. I highly recommend J for any of your electrical problems."

"We originally hired Precision Electrical Services to fix faulty outlets and fuse box. We were impressed with their communication, professionalism, and quick scheduling that we hired them to install a ventilation / light fixture in our bathroom. I canâ t say enough good things about them and will use them for all of our electrical needs moving forward."

"Tim P, Generator Advisor, visited our house and gave on the spot estimatesâ ¦..he was GREAT. Licensed Electrician who knew his business and was easy to speak with. Timely communications and responses to text messages! Tim was helpful answering questions after the generator was installed. We talked to 5 Generac dealers and a Kohler dealer. Cotti-Johnson had the best pricing in the South Shore area. We highly recommend this company. If you are thinking about buying a standby generator, Cotti Johnson is the company to callâ ¦..Art V"

"I hired this company for spring cleanup, and when they got here they were able to do so much more They edged all my beds. They mulched everything. They filled my new raised beds with loam. They cleaned my two ponds. They went way over and above what I expected, I would recommend them highly to anyone. They .were professional. They were courteous. They left nothing behind. It was absolutely the best experience I’ve had hiring someone in a long time. I couldn’t be happier. I would highly recommend them to anyone for any projects."

Generator Install questions, answered by experts

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.

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.

Potential benefits of using a natural gas generator include reducing your carbon footprint, lower likelihood of carbon monoxide exposure, budget-friendly operating costs, and low-maintenance, continuous fuel supply. Some possible drawbacks, though, include higher initial installation costs, dependency on a natural gas supply, and installation complexity. Keep in mind that pros and cons will vary based on the type and brand of natural gas generator. 

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.

It might seem counterintuitive, but installing a generator transfer switch will save you money in the long run. While you’ll have to pay between $400 and $2,500 to have the transfer switch installed, you’ll recoup that amount later on when you don’t have to pay for expensive repairs to your appliances, devices, and electrical system that may have burned out, overloaded, or stopped working due to a sudden loss of power or an incorrect hook up of a generator to your home
