621 Energy, LLC

Established: 2011

EnergySage Rating Value: 5.0 from 2 reviews

The last review from EnergySage:

First Congregational Church in Melrose selected 621 Energy after careful review of 6 quotes provided by EnergySage. 621 Energy was responsive to the needs (and sometimes delays) of a non-profit, worked with us to get the best offer to our capital campaign committee, and once a contract was signed moved quickly through a very rainy fall to install our system. They have proven to be a true partner to our organization.
