The technician who came to assess and take metrics on our home was great: professional, thorough, and clearly very skilled. I'm looking forward to a proposal based on this analysis.

We recently had EarthTech conduct an assessment and maintenance of the geothermal system in a home we purchased. From the very first inquiry they were great to work with, very responsive and helpful in determining what we needed done. The technician, Elijah, did an extremely thorough job evaluating our home & system and performing necessary maintenance on our units. We have much greater clarity and peace of mind heading into the winter. Highly recommend EarthTech for your geothermal needs!

EarthTech designed and installed a groundwater heat pump system in our 2400 square foot home. We already had a MassSave approved insulation and weatherization upgrade completed, which was necessary to install the groundwater heat pump. EarthTech was professional and pleasant to work with at all times. The installation is professional and neat. The project came in on budget with no surprises. EarthTech also helped us with the paperwork needed to obtain a MassSave rebate. We are very pleased with how the system is working. It has kept us warm in a chilly May and cool in a hot June. We are optimistic about how the system will perform during the next winter.
