Stay Away! Not worth engaging with their consultants!
Their energy consultant, Mathieu Hutt, says you will receive a FULL refund on the security deposit that will be refunded post-installation. You pay this amount in USD and are refunded in USD, losing out on the currency conversion fee because that's all they will refund you. He also tries to push down products on you without you fully understanding the true costs involved with installing their energy saving products.
