I knew nothing about them other than Meeting Peter who gave me the estimate for a central air install. I had to have vents installed throughout my house. I also had a hot water tank installed and upgraded the electrical service plus nest thermostats. They had very professional and very friendly people working for them. I would like to give a big shoutout to Brad, Steve, and Bryan. These guys answered all my questions and always filled me in throughout the entire 3-day process. Hard workers. Thanks, guys. - David R. Couldn't Be Happier We couldn't be happier with Cotti-Johnson, who installed a new Lennox central AC system (including duct work) in our house! Peter in sales is a real pro and he did a great job of steering us in the right direction with a two-zone Lennox system. Cotti Johnson was the 4th and final company that gave us a quote and they did not disappoint. The price was right, but what sold us on Cotti was Peter's knowledge, honesty, and the fact that he didn't try to up-sell us on a system that we didn't need. The entire installation team was excellent and we came home to a house each day to find not one speck of dust. The air handler is located in our attic and the team arranged all of the duct work in a way that still leaves us with a TON of storage space. Right now all we can think about is using our new AC on those hot summer days!!!!! Thank you, Peter and the Cotti-Johnson team!!!!! - Kevin K. 774-768-5154 Local Office 30 Waverly Street Taunton, MA 02780 Map & Directions [+] Quick Links Home Services Contact Us Privacy Policy Site Map Follow Us Corporate Electrical License MA #22630-A Corporate Sheet Metal License # 355 Lead-Safe Renovation Contractor License # LR001806 Home Improvement Contractor License # 177092 © 2021 All Rights Reserved.
