"Joe, the AirCo sales representative, was very professional. He actually asked for my feedback on priorities for a new boiler. This was important to me because the boiler sits below our family room, and the noise level of the boiler was as issue. His proposals listed several boiler options, based on heating efficiency, which were competitively priced. The installation was run by Steve, who was able to fit in the installation the next week. Steve, and his crews, were punctual and courteous, and the installation went smoothly. It's only been a week, but I am very pleased with my Bosch boiler, the quality of the work, the price paid, and the timeliness of the installation."

"Set up an appointment for an initial 10 minute phone call to talk about what we wanted. Tom ended up spending 25 minutes with us and answered a ton of questions. We subsequently set up an appointment for an initial pre-build inspection of the foundation, framing, roof, and windows. Tom was very thorough. He obviously knew his stuff. Pointed out several items that needed addressing before the insulation and walls went up. Couldn’t be happier with the amount of time he spent, how thorough he was and how much he listened to all my stupid questions and answered them in a language that I could understand. We will have him back before the next phase starts and probably a couple more times before we close. Anyone building a house or buying a new home would be wise to hire Tom. Great piece of mind and cheap insurance. Plus, he’s a really nice guy to boot."

"Infrared Diagnostics is an independent Energy Auditing company. Flemming is great to work with because he's a consummate professional at what he does. Very knowledgeable about building energy issues and in my case I needed an expert I could trust to tell me what I needed and to prove it with science. Flemming did exactly that by providing me with an infrared scan to show me what and where the problems in my home. With this information, and Flemming's recommendations, I can now speak to contractors intelligently and direct them to perform the work that I need done to make sure that the problems are resolved and the job is done as efficiently as possible in a way that saves me time and money. Thanks for your time and advice on how to resolve the issues Flemming!"

"We cannot say enough good things about Dolphin Insulation. They replaced the existing insulation in our entire house and addressed some mold related issues we came across along the way. We are delighted with the results. Our house is much tighter and drafts we used to feel are gone. The whole process took about 2 weeks, including removing the old insulation, prepping and blowing in the new insulation. We are talking about the roof over a bedroom over a double garage, the main house and the cathedral ceiling for a family room. Go to their website and see some of the projects they have tackled. What you see is what you get. From our very first contact right through the installation process everyone we came into contact with was professional, informative and very helpful. Dolphin was upfront on their timing for the project, in what was their busiest time of the year, and called us ahead of time to let us know they were running a day or two late. All the crew who came to our house throughout the process were polite, friendly, hardworking and took the time to answer any questions we had. They were flexible and worked around other contractors who were in our house at the same time. Dolphin adapted to issues that cropped which resulted in more work that they took on. Every day they cleaned up after themselves as best they could. Amanda, the owner, even stopped by towards the end to bring over some parts they need to protect lights in our family room. It is also clear everyone believes in the technology they use, and that what they do is more than just a job for the crew. As far as we are concerned this is the best and greenest insulation solution out there. It takes time to install but it is well worth it. No toxic fumes and you don't have to move out of your house. This is not the cheapest solution you can come across but it is worth every penny."

"We consider ourselves very lucky for having chosen New England Clean Energy as our solar installer. From the beginning to the end of the project, NECE was responsive, punctual, helpful and very focused on giving us the best - we always felt they put us, their customer, first. We are very happy customers, secure in the knowledge that no matter what issues may come up with our system, NECE is a phone call or an email away, with courteous, prompt answers. We wholeheartedly recommend them."
