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.

We had a Mass Save energy audit through NEEECO and decided to get replacement windows in our house. NEEECO's employees are very professional and gave us lots of information to help with every decision. They assisted with the Mass Save loan application, and the work was completed quickly and efficiently. If you are thinking about how to make your home more energy efficient, give them a call!

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

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.
