Our customers describe Neeeco best of all:

I highly recommend NEEECO

I highly recommend NEEECO as well! I had one of their auditors Justin Bessette do an awesome job on my Home Energy Audit the other day. He was very personable and professional. He clearly explained all the mass save initiatives and answered all my questions concisely.

Dariusz Makowski

A 5 star experience

I am very impressed with Dani and the crew at Neeco. From the audit to the install and everything in between it has been a 5 star experience. Communication has been what you would expect from professionals. The install is timely and clean. I would recommend Neeco to my family and friends.

Mary LaBombard

Very pleased with every interaction

I worked closely with Danielle in NEEECO's office and Fabio, the installer. I was very pleased with every interaction on email, the phone and in person. The work was done on time with no surprises and the quality of the installation in my 100+ year old house was outstanding.

Steven Gag

I highly recommend NEEECO!

I highly recommend NEEECO. Richard did our Home Energy Audit (if you have not done one of these, do it ASAP. Massachusetts subsidizes lots of upgrades). He was professional, knowledgeable, and answered all my questions. Dan and Jose then did air-sealing and insulation work. They were meticulous and professional. They explained what they were doing and did great work.

Kevin Arritt

Very professional and hard working people.

Had a home energy audit done by Neeeco. Very pleased. Got a bunch of free lightbulbs. The best thing was when they did the sealing and insulation. Can't say enough about Justin and the work crew that came to my house. Very professional and hard working people. Justin, in particular, did a great job providing updates throughout the day and made sure everything was cleaned up at the end of the day. Great job!

Dave Crowley

Very professional outfit

Very professional outfit. Brian B. was my assigned PM. He showed up on time, was very thorough in his explanations, and I got free light and water fixture upgrades. Would definitely recommend them.
