"First Congregational Church in Melrose selected 621 Energy after careful review of six quotes ... 621 Energy was responsive to the needs (and sometimes delays) of a non-profit, worked with us to get the best offer to out 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."
