Terrible experience with Guaranteed Comfort And Energy by Jerry C via Customer Lobby on 11/17/2014

My experience was totally different; like night and day from what I have read. Jim and Guaranteed Comfort did not treat me with any of the respect from what I am a custom to. He never returned calls when I had issues. He did not stand…

We have now had 2 Ameren bills since Guaranteed Comfort & Energy worked their magic at our house. Last month our bill was $80 and this month $100. This is exactly 1/4 of the amount we previously spent at the same time last year. I am SO IMPRESSED by John & Lynn F via Customer Lobby on 6/6/2014

Cannot say enough about how pleased we are with Guaranteed Comfort & Energy crew. Add that to 1/4 the amount of our last two bills from Ameren compared to last year. You all are the best!
