"We have had NECS to our home several times for different projects: energy audit, attic insulation, and wall insulation. These are very professional, considerate, and honest people to do such work in your home. Our house is much more energy efficient after all we have done. Insulation pays for itself very quickly, and NECS took care of all incentive programs for us. You won't go wrong with them."

"The service was great. They gave a lot of really helpful suggestions. They replaced our bulbs with low energy bulbs. They put in weather stripping in areas needed as well. They were great to work with. They gave a detailed report on how to lower our energy usage."

"I rated them B for responsiveness because the first time I called I was told they would call back and they did not. As you would expect the price was too high. They ended up tightening a union of pipes and testing to see if it leaked. The first time it was tightened, it did leak and they went to replace the part. A second tech tightened it further, retested and it did not leak.Not sure why the first person didn't tighten further. So the question remains; is the problem solved. We will see when the heating season begins. The techs were young, personable and seemed knowledgeable and willing to answer all my questions. They spent over two hours here, some of it waiting to get the heating up for testing. Had a $50.00 coupon or the cost would have been over $400."

"The work he did was good but they did charge too much for the work. They did try to upsell other services. The charge for the additional work was too much. The charge for the part was very high. I did not have them do the additional work."
