"We needed our boiler replaced and had multiple companies come and look at the job. We ended up selecting Sila as we read good reviews on the company. Sila surpassed our expectations. The tech who performed the install (Gage) was on time, communicated the entire process to us from start to finish and did a tremendous job. He also made sure to clean up afterwards and was very professional. We would absolutely hire Sila again!"

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

"The Office did give them register to come with them. The guy who Estimate my furnace had told me when gonna be coming to install they will bring it but they didn't. If Office can send someone to bring i will appreciate."

"The thermocouple on my gas-fired boiler needed to be replaced, and the pilot needed to be cleaned. The tech was helpful and forthcoming with information. Took about an hour, as my boiler does not have easy access. Would hire again!"

"Waiting for a new boiler mine was defective"

"Excellent response time, installation and knowledge base!"

"These guys were extremely fast to respond , visit the site and generate a quote and all in a matter of a few hours from the time I inquired on Home Advisor. Their price was very reasonable but they presented only one type of a High efficiency boiler install option for a wall hung unit to replace my old low efficiency floor unit. I was not thrilled with the ideal of hanging a new furnace on my cinder block chimney so I decided to wait and get more quotes from others. However I went with a different contractor which charged a bit more but offered a floor unit ."

"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 sales team and installers were professional and responsive. I had contacted other companies for quotes. Peter and team came right away and were considerate of my home and health. The others were not. When looking at my home they gave me the options needed for our unusual configuration and home history. They wore PPE and were meticulous . So happy to have a climate controlled home!!! If that is what you want call Majic!"
