Hard working people

Dave Crowley, Lynn

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!

Meticulous! Great work

Kevin Arritt, Burlington

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.

Very polite and friendly

Miranda Grace, Waltham

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.

A 5 star experience

Mary LaBombard, North Andover

I am very impressed with Dani and the crew at Neeeco. 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 Neeeco to my family and friends.
