Black Diamond Energy

From the first phone call to the final cleanup, Black Diamond Energy was amazing. Every member of the team was responsive, timely, professional, and had a tremendous amount of respect for the customer and the job. We are a couple months out from the project being completed, and the ductless units are cost effective and have transformed the comfortability of our house. The external ductwork was completed thoughtfully and with precision so that it is barely noticeable. Joe and Black Diamond Energy even helped us with the MassSAVE paperwork so that we were ensured to receive the rebate. Of all the companies I met with, Black Diamond not only had the best price, but also had the highest quality product and installation (please feel free to contact them if you would like to get in touch with me

Just moved into a new house and discovered the central AC was not working properly. I called Black Diamond Energy and Mateus came out the same week. He cleaned and fixed out unit in no time. He was great! Very easy to work with and very professional. I will definitely use Mateus @ Black Diamond Energy again! Highly recommend!

We had an amazing experience with Black Diamond Energy. Not only is the product exceptional, but it has completely transformed out home for the better. The staff were professional and made the process easy. Thank you Black Diamond Energy!

Joe did a wonderful job preparing three units in my home for the season. He diagnosed a small leak and fixed it promptly. Professional job.

BDE found a creative way to outfit our home's unusal configuration with heat pumps, beat the competition in pricing and did an excellent job overall.
