      "Exceeded My Expectations!"

      Steve and his team did a great job updating the wiring on our 120 year old house. The work that they did was to install a new 200 Amp service with a new breaker panel and some new circuits for the electric water heater and an air conditioner plus installing some new lighting in the dining room, kitchen and back yard. The also did a whole house evaluation of the existing wiring.
      They took pride in their work, had a can do attitude. They know old houses and really seem to love working on them. Steve also explained everything to excess, which I really liked.

      "Very Responsive!"

      Outdoor repair of electric power components after fallen tree damage. Company was responsive on short notice in an emergency. Tech, Sam, was extremely knowledgeable, professional and helpful, doing a full evaluation of our electrical system, offering several options, and completing the work requested. Very positive experience.

      "Recommend Every Time!"


      I called because the air flow in one room was too high and always much cooler than the rest of the house and this is where my dad was staying in hospice. Cotti-Johnson sent someone out the next day to check system and validate its operation. They ultimately contacted Eric, who was in involved in original install the previous year and he came out the following day to adjust the dampers in the attic which solved the problem. He also showed me how to do this on my own (very simple). I was pleased with response time, professionalism and care and would highly recommend them.

      "Quick & Professional!"


      Four men did their jobs quickly and professionally. Happy with new heat & air systems. Small glitch do to the power outage. Mel, in the office had Ben come back out to check and found the problem quickly. Thanks to all from Mel in the office to Ben and his crew. Both Mel & Ben are very personable people to work with, and knowledgeable in their jobs.

      "Great Communication Skills!"

      I can’t say enough about the service we received. We engaged this team to assist with an internet issue we were having and ending up having them assist with wiring for our ductless ac/heating unit in the garage and they also installed a generator. Stephen’s level of professionalism and attention to detail and communication skills exceeded all expectations. He carefully explained everything in detail ensuring we understood what they were doing, how long it would take, and how it all worked. Ashlee was equally as professional and extremely task oriented. Everything was completed on time or earlier and I could not be happier with the service. I will definitely become a repeat customer. Thanks again for the great service.

      "Very Professional!"

      Ordered a Mitsubishi mini split AC. Install delay was on us as we needed to upgrade electrical. Company’s electrician worked with us the following month. Installers on time, efficient, great communication throughout install and they gave a good demonstration as well as going through the manual. Highly recommend: all communications were prompt & professional from Mel in the office to electrician and installer. Highly recommend. J Forgeron returned 12/17, earlier than expected 👍 to take care of a small item identified by the local electrical inspector.

      "Great Job!"

      Patrick and his crew did a great job. Patrick first went through the house with us to confirm the best locations to install the inside units as well as to determine how best aesthetically to locate the necessary exterior conduits including going all out to conceal them under deck or alongside gutters and downspouts when possible. He answered all our questions in detail and was a pleasure tom work with. We are very happy with the results.

      "Very Knowledgeable!"


      Troy was very knowledgeable and great I’ll be most definitely be using this company again they was right up the street from me and he told me will I be using them again and I told Troy yes I will because the way that he was proper and did the job after another company denied the job but Troy knew what was going on and went right for the problem.

      "He explained what went wrong with my furnace and knew of the problem and fixed it immediately."

      Just want to pass a long compliments to the service man who cam here yesterday. His name, I believe, is Tony. He did a terrific job; very fast, thorough; he was extremely polite, he put on his booty over shoes before he came in; he answer all of my questions; he mentioned he came from Bourne for a furnace call down there. Being a 80 senior I appreciate some warm in my house especially in the earlier mornings. He ran the AC and heating systems several times to make sure all is well.

      He explained what went wrong with my furnace and knew of the problem and fixed it immediately.

      DO PASS ON MY COMPLIMENTS TO HIM AND OUR MANAGER. TONY DESERVES A RAISE.

      "Respectful & Professional!"


      Every person that came to our house to replace both boilers was respectful and professional. They showed up on time, cleaned up after themselves and even finished the job faster then I was quoted! I was very happy with my experience from my first call with a sales rep through the final installation details. I would highly recommend Cotti Johnson to my friends and family!

      "So Glad I Went With Cotti-Johnson"

      So glad I went with Cotti-Johnson. I interviewed 6 different companies and decided on them. 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.

      "Excellent Business!"


      From start to finish this was an excellent company to work with. Mark who came to give me an estimate answered all my questions, took photos to show exact locations of ductless system, outlined everything clearly. Very good value compared to other companies I received estimates from. Professional, courteous crew came to do install. Very respectful. I highly recommend Cotti-Johnson, Great company!

      "Excellent Work!"


      I am so happy with the work Dan, Jay, and every associate has done on our condo. They installed a bathroom fan in a very small bathroom on the 3rd floor and it is so quiet and works excellently. I feel that Dan and his crew are extremely competent and has my family’s safety as a priority. They do excellent work and clean up too! I will continue to call them for our electrical needs.

      "Very Satisfied!"


      Adam did a great job of explaining to me what he was doing for our first annual furnace maintenance (2 gas systems installed last year). He arrived on time and was very courteous and professional. We are very satisfied customers.

      "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!!!!!

      "Amazing Service!"


      Tyrone was AMAZING!!! I was frantically calling HVAC companies to come out because my central A/C stopped working on a 90 degree day. No one else was available to come out asap, but Tyrone called me back and came within 45min. He was very professional, nice and knowledgeable. We will definitely have him come back for all our HVAC needs in the future!

      Technician arrived when expected, with a call 1/2 hr. prior to arrival. Prompt courteous service call. Before leaving he asked if I have any questions. Very professional and courteous.

      "Awesome Job!"


      Sam did an awesome job installing backup generator inlet at my house. He was very professional and made sure that I understood how to switch over to generator power when it is needed. He also asked if I have any questions. Thank you very much for your service!
