"Bought a heat pump from them 3 years ago. Cooling has never worked in the summer, heating fails twice every year in winter. Even when it works it can't heat the house over 65 degrees. The problem is always the same, a leak in the line they installed. Instead of fixing the leak, they refill the refrigerant every time and charge me a few hundred dollars. Every time I have helpfully told them about the continuing leak issue, but they don't listen. Now that the heat pump is out of warranty they are recommending a $3000 repair of the problem they should have fixed three years ago."

We take great pride in our experience, expertise, quality, and customer service that we provide to meet the consumer's needs. It is our mission to provide excellent workmanship and complete customer satisfaction from start to completion of a project. In order to understand the needs and expectations of our customers, we take great care to work and communicate with every customer in a professional manner. Our reputation is based on service, safety, and quality, regardless of how large or small the job.

"We were in the market to convert off oil and switch to a heat pump system. CRM Green Energy Consulting helped us every step of the way. They arrived on time and were very professional during the home assessment process. We agreed to the proposal and set up a time for installation the following week. Throughout the whole process CRM was communicating with us on progress. There was a placement issue for one of our mini-splits and one of CRM’s Carpentry team members came out and opened a wall and patched/painted like they were never there. Super friendly team members and very knowledgeable on green energy and home heating efficiency. At the end of the project they sat us down and taught us how to use the phone app for our GE mini split unit. They helped us fill out of MassSave rebate form as well! We couldn’t be happier with CRM Green Energy! We are so glad we chose them for our heat pump project!"
