Indrit came out this morning to deliver propane. Since we were worried about a leak, he took the time to test for one while answering my brother’s questions. When he found one he took the time to remedy it and explained how my brother could test it himself monthly. He was friendly, helpful and knowledgeable! Later this afternoon Chris C showed up stating they had noticed an issue with our sensor, that the connection was intermittent and he replaced it. All the while, just like Indrit, he explained everything to my brother so we understood what was going on and answered every question. He also was friendly, helpful and knowledgeable! You have first class excellent employees! Highly recommend CES for all your energy needs.
