"Jason and his team with Cotti-Johnson did an excellent job updating our electrical boxes, installing the washer/dryer hookup, and getting us setup with a generator! Sam, our assigned electrician, even took the time to go through the entire operation of the generator from A-Z. I would definitely recommend them for any electrical work!"

"Russell performed the highest quality installation of the entire electrical system in my new 4 car garage which included high voltage tools like a compressor, lift, welder, heating unit, etc. His design recommendations, availability to answer questions, and overall workmanship made for a great experience. Not only did it exceed my expectations, but also passed inspections with flying colors. If you’re looking for honest, high quality results that from someone who won’t rake you over the coals, call him!"

"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."

"Expensive but professional. The electrician that did the work was excellent and seemed.to enjoy explaining what he was doing and why it had to be done that way. I felt like I learned something while he installed ceiling lights. He also cleaned up after himself like he'd never been there."

Customers say: Quick response

"I called Anthony about installing a transfer switch and outside outlet for a portable generator. He returned my call quickly and discussed the job over the phone. I was given a fair price for parts and labor. He arrived on time for the installation and spent 3.5 hours doing meticulous work. He answered all my questions regarding the installation and operation of the equipment that was installed. He even spent time showing me how to properly operate and care for the portable generator. Anthony was professional, friendly and courteous. I highly recommend him for any project."

Generator Install questions, answered by experts

Most homeowners won't be able to claim a home generator as a tax write-off. However, a whole-house generator may be tax-deductible in certain situations depending on its purpose. For instance, if it's needed to power essential medical equipment, it may qualify as a medical expense deduction. Also, in some cases, businesses can deduct a generator as a business expense if it supports operations. Always consult a tax professional to determine eligibility based on your specific circumstances and the applicable IRS regulations.

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.

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.

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 run on a variety of fuel types, ranging from natural gas to solar power. Keep in mind that fuel costs varying by type:

  • Natural gas: $2,000–$21,000 per year 

  • Liquid propane: $2,000–$21,000 per year

  • Diesel: $3,000–$20,000 per year

  • Gasoline: $500–$3,000 per year

  • Solar generator: $2,000–$25,000 per unit

  • Battery backup: $10,000–$25,000 per unit
