Recent Review: This is the second time that we have contracted with Suffolk Systems Inc. for the installation of a geothermal heat pump (we have multiple units). The first time was 2 years ago, and the experience was so positive in respect of quality and professionalism of work, that we did not hesitate to use them again. This second experience was just as satisfying - Dan and his installation team were punctual, professional, neat, and thorough. The work was complicated by nature, but they handled it all expertly, and completed it timely. The new unit is operating as expected. Lori in the office is consistently attentive, responsive, and helpful. We are extremely pleased with all aspects of our experience with Suffolk Systems Inc.
