Our customers describe Neeeco best of all:

Very polite and friendly

Miranda Grace

We recently had a Home Energy Assessment done by NEEECO. Brian was very polite and friendly and took the time to explain everything he was doing. Every light bulb was replaced, our shower head was replaced, he checked our heating system and insulation, and pointed out what rebates we were eligible for.

Very pleased with every interaction

Steven Gag

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.

Meticulous! Great work

Kevin Arritt

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.

Wonderful, cheerful, efficient

Anne Kern

Wonderful job by Brian Besssette! Extremely understanding. Very Professional. Cheerful. Efficient. Love Mass Save. Staff this year have been outstanding!

A 5 star experience

Mary LaBombard

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.

Great job--very pleased

Dave Crowley

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!
