Get matched with top boiler installation pros in Dighton, MA

"John G. did an excellent job evaluating the functioning of our boiler and performing annual maintenance for it. It was his second time taking care of the boiler for us. He quickly answered the minor questions that I had, and he advised what would be cost-effective in addressing the issues that I raised. In both the instances in which John G. has serviced our heating system, I found him to be knowledgeable, courteous, and focused on saving us money, whether on heating costs or future upgrades."

"Dylan did a phenomenal job installing a new boiler as well as diagnosing an issue with another boiler. Highly recommend."

"JT called and asked if he could come earlier than expected, which was perfect for me. He was extremely thorough reviewing our electrical system and the finished product of the work he did (installing a new 220v line for an outdoor hot tub) was clean and efficient. He was a joy to meet and speak to, incredibly nice guy. Price was reasonable for the work. I would 100% recommend JT and Cotti-Johnson again!"

"I called Nick, on a hunch from wife, and he showed up as planned, and even offered to do the work right then. I bought a faucet for him to install, but it wasnâ  t the right size, but Nick had one on his truck that looked good and he installed it right then. We had another problem with the faucet in the kitchen, that was leaking, and I purchased some time ago from Home Depot, he couldnâ  t repair it do to some inferior parts on that faucet, so I purchased another faucet from Nick, and had that installed, as well. Job was completed and he takes pride in his work, cleaned up and went on his way! Now thatâ  s how a job should be done, on time, neat, and professional from beginning to end, Would recommend him to anyone. Thatâ  s my new plumber , For Sure !"

"Excellent response time, installation and knowledge base!"

"Customer Service was excellent, install was excellent, highly reccomend."

"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 them to remove and install an Armstrong heating and A/C system in my son's house. Tim came out and gave me a quote along with a great education about forced hot air heating and A/C systems. Shane and Marty showed up every day for a week to remove the old ducting and install new ducts and the system. Shane is very knowledgeable on the systems and his customer rapport is outstanding. I had many questions during the installation and he always took the time to answer me completely. We had a couple variations during the install and he was accommodating as well as making sure the changes would not adversely affect the system. I am extremely satisfied with MajicAir and highly recommend them to anyone in need of a system."
