I enjoyed my experience. He made the most use out of his time and still was able to explain items to me and answer my questions. My only negative was that in replacing my flue mortar fell off and it was not repaired.
Response from KC Water Heaters:
Thanks for taking the time to leave feedback, I was totally unaware of your issue until I read your feedback. Update: Wanted to report that we returned to the job to tuck-point a small section around where the flue enters the chimney. It was about a 5 minute job and we always stock mortar and repair tools on the truck. This was such a minor piece that had fallen it was not noticed by the installer.
