"Keith the owner came out immediately to look at our heat pump. He answered every question I had regardless of how silly they might have been- I had zero knowledge of what was needed to fix or replace our system. He was on time and courteous of us having a newborn in the house. He was able to set up a time to replace our heating system that worked for our schedule within two weeks. The guys that work for him are fantastic. They made sure everything was working properly, cleaned up after themselves, and helped me set up our new thermostat. We can't thank them enough for making this whole process so easy. Keith and his team took the time to explain to us every detail from equipment needed, installation, maintenance, and the rebate forms."

"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"
