"Dylan was amazing. My hvac person retired & I found Dylan when my Central air decided to act up. He explained my unit was in approaching its last days but he could attempt to repair it if I wished but I decided it was time to do a complete new heating & cooling system & he made it a easy process. No pressure & no stress. Now we’re ready for the heat wave that’s apon on us. Thank you Dylan & your team for your professionalism & great service. I highly recommend & they’re my go to for plumbing as well as I’m about to have them replace my hot water tank before it becomes an issue"

"The installers were great, removed the 70 year old crumbling boiler and all the old valves, expansion tanks etc. and installed the new boiler and hot water tank in just 2 days. They explained what each valve and control did after they finished the installation. No extra charge for removal of the old equipment and they left the basement cleaner than when they arrived."

"Everyone I spoke to at Cotti-Johnson from the estimate through to installation of my generator were polite, professional and a pleasure to deal with. At the outset, the scope of the project and its cost was explained to me in simple and understandable language. The installation took place precisely on schedule and was completed within 3 hours. I received the necessary follow-up calls from the office to ensure the work was done to my satisfaction. I couldn't be happier with Cotti-Johnson."

"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."

"Robert is very honest and forth-coming about the intricacies of a job. He explains his concerns and also educates the customer about what the customer should be thinking about. He is prompt and polite. His pricing was very fair also. We just got to him too late in the winter heating season to act right now."
