Reliance The Furnace Company Edmonton

Nathan provided us with great service way above and beyond what we expected, delivered in a very courteous and congenial manner. He is to be commended.
Only negative comment I have is with regard to Reliance call centre. When I first called on Friday I was asked if it was a plumbing problem or an HVAC problem, since our furnace is run off our hot water tank, I did not know, consequently a was plumber sent. ApparentIy there was no record of our purchase of the hot water tank in May, 2017. I was then informed it was an HVAC problem. Another gentleman arrived and we were informed that it was a plumbing problem. A third gentleman arrived on Monday, Nathan, and he had the correct part and it was promptly installed. Unfortunately the furnace quit during the wee hours of Tuesday. I called the service number and again got the call centre. Again I was asked to determine whether it was a plumbing or HVAC problem and that if the service provided today was not related to the original problem I would be charged. I was not happy with this comment at all, I am not a plumbing/HVAC diagnostician. Your call centre could do better.
I subsequently texted Nathan and he came very promptly and now the problem seems to be solved.
Thank you
