"I searched for a reliable company to install a whole house generator at my home. I read all of the reviews and discovered that Premier Generator operated by Paul Foley Electric of Carver MA was the most highly recommended of all generator services in my area. We found Mr. Foley to be unusually thorough and forthright in making his proposal to us. Jeannie, the business manager is congenial and is willing to accommodate customer needs. When selected, Mr. Foley's installation crew reflected Mr. Foley's values for neatness, attention to detail and for customer service and satisfaction. Additionally, Mr. Foley installs Kohler generators which are reputed to be industry leaders. We have had the Kohler generator for three years and found it to be quiet and reliable. It provided uninterrupted electric service for the whole house for 4 days when Eversource power was interrupted by a severe winter storm. We engaged Foley Electric to service the generator every fall. Nathan, the service technician will do whatever is necessary to please the customer and reflects Mr. Foley's emphasis on serving the customer. I watched as he serviced the Kohler motor and generator. He follows what appears to be an established procedure and is careful to treat the unit as if it were his own. He willingly and patiently answers questions in a way that anyone will understand. He gives the impression that, while he is at my home, that his time and attention are devoted to meeting my requirements - without unnecessary distraction. He asked about my interest in establishing WiFi monitoring and assisted me in successfully establishing the connection on my cell phone. You just can't ask for or expect better from any service technician. I most highly recommend Paul Foley Electric for home and commercial needs."

"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!"

"Christian Zimbone presented a very competitive bid on our project to upgrade our electric service and installation of an electric car charger. He came in on budget and did a phenomenal job. Everything neat, clean, and 100 professional looking. He was very responsive, informative, and very friendly to work with. He knows his stuff! (...and we had several other estimates with varying dubious info). Highly recommend and will definitely hire again for any future needs."

"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"

Generator Install questions, answered by experts

The average cost to install a home generator is $5,200, but total costs can range from $500 to $18,000 or more. The final price depends on several factors, including the generator's size, type, brand, fuel source, and the cost of labor and assembly. The generator's size is the most significant cost factor, as units that can power larger homes with higher energy demands cost more.

Cost breakdowns by generator type are typically as follows:

  • Portable or Emergency Backup Generators (1kW–7.5kW): $500–$2,000

  • Partial-Home Generators (9kW–20kW): $2,000–$6,500

  • Whole-House Generators (22kW–48kW): $5,000–$18,000

To ensure you get the right size unit for your needs without overpaying, consider hiring an electrician to calculate the electrical load of your essential appliances. It is also recommended to get at least three quotes from qualified installers to find the best fit for your budget.

Natural gas generators are designed to run for extended periods of time, such as power outages during a natural disaster. Since there’s no limit to the supply of natural gas, they don’t need to stop for refills. However, generators do need maintenance, including pauses to check and add oil. Constantly running them will also cause a lot more wear and tear, leading to a shorter lifespan.

Yes. You can connect your home back-up battery to a generator with its designated charger. Be sure that the output of the generator matches the input requirements for the battery for best results.

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.

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
