Had a complete new oil furnace and hot water system installed by them and couldn't be happier with the service and the pricing. They were extremely competitive with pricing. They had the whole install completed in a day and a half, which included removal of all the old equipment. The techs were very knowledgeable and respectful ( including wearing a mask the entire time in our home ). Would recommend highly!

Once the job was completed I even received a follow up phone call from Jake to make sure everything went well, that the house was heating sufficiently, and to make sure I was satisfied with the work. I could not have been happier with my choice to go with Climate Design and Jake. I would absolutely be using this company again in the future and for sure will be recommending Jake and his team in the future.
