Get matched with top central a/c installers in Cohasset, MA

"We are overall very happy with the project. Sila had to install a high velocity air conditioning system in very limited space. They provided a timely quote and showed up and did the work professionally and on time. There were a few hiccups, such as the installation of the hatch to the attic space, but Sila’s carpenter agreed to fix the problem at no additional cost to us, so I consider that to be excellent service. After two weeks, the system has been performing exactly as we hoped."

"Highly impressed with HL Bowman and would definitely recommend them. They provide top notch service from beginning to end. The initial contact and scheduling was super easy, the quote process was really extremely informative and the install was faster than promised, they cleaned up and were super professional. You can’t go wrong with these guys."

"My Central AC unit went out; the box outside smelled like something had fried. I called NETR, and they said they would send a technican over in a week. The technician came on time and promptly inspected the unit. He reported that the capacitor had blown, and told me that he had a spare back in his van. The labor was covered by the diagnostic site visit fee, it was just the parts cost. I told him to proceed and he replaced it. My AC was back up and running within the hour."

"Dylan has done a wonderful job installing my Mini Splits. Dylan was professional, worked hard, cleaned up, and completed the job in a timely manner. Also, he answer all question and kept me updated throughout the job. I highly recommend him to install A/C."

"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"

"The house I purchased was built in the 1950's. The house had the duct work for forced hot air but was heated by oil. Ross installed a natural gas furnace, coordinated for the removal of my oil tank and installed central A/C. The quality of the work was great and so is Ross's professional manner. He and his team were very efficient. I would highly recommend."

"On one of the coldest days In January, 2024, the team arrived at our home at 9:00 am. Our 24 year old boiler was removed and the new one was installed. Thankfully, we had heat by 3:00 pm. The work site was cleaned and the installer explained all the safety features of the boiler. All went smoothly and we are satisfied with the work that was done."

"Had BB install a Bosch heat pump in place of my AC. this thing is awesome! Love new tech, told my cousin to do the same with BB, he’s getting it done next week!"

"They showed up and fixed our central air units. Definitely recommend!"
