I was advised to upgrade my water tank to a power vented one for a few dollars more per month rather than keeping the previous one which requires my vent connector to have a sleeve put on or its liner be corrected or changed and that would cost me hundreds of dollars. Phoned Reliance and discussed about this. They sent 2 polite, very organized gentlemen Dylan and Jon. They said they are brothers. I believe them because they have similarities. Well, anyway, they are within the scheduled time frame. Jon arrived first and almost did everything from the beginning, emptied the water tank until the cleaning/tidying time. Dylan came in time to help Jon change the tank and to drill the hole from the inside wall of my house in order for the pipe go through outside the house. Just this drilling process alone, Dylan said he was able to waive $100 and this is a big savings for me. He did this without me asking for it. Thank you, Dylan and Jon from Dynasty Air Systems Ltd. on behalf of Reliance Home Comfort for installing my tank and for doing a wonderful job.
