I don't usually write reviews, but I just saw a W5 episode similar to my experience with Advanpro and it prompted me to write this. I had a 2 person crew show up to service my furnace (1 of my 2 furnaces had what I believed to be an igniter issue) a while back. I showed them to the basement and left them to do their work. About a half hour later, the guy comes upstairs and says "I have bad news" ... "you need 2 new furnaces". I'm like, "whaaaat??!". He goes on to show me a video on his phone of "my" cracked heat exchanger and said that he just took the video 5 mins ago in order to show me the problem. (I was not there when he took said video, nor did he take me to the furnace to show me, nor did he do a water/steam test, which, I learned is one of the only sure ways to find cracks - I truly believe that this was a random video used as a scare tactic to purchase all new gear). I was shocked. I had questions regarding installing the new furnaces and he made a quick phone call and came back to me saying he could do both for around $6500 - He didn't measure anything, or do an actual written quote or give me any product options or anything like that!! I was stressed and in shock, so I said sure, book me in. After they left, I had the worst gut feeling that I'd been had. I called Atco to test for CO leaks, and they detected nothing. I felt better after that and called Advanpro to cancel those 2 new furnaces. I ended up getting a 2nd opinion from a reputable company and they had nothing to say about cracks in the heat exchanger, and that the furnaces were running fine, (in fact, he said that they were in excellent shape!) but may be worth thinking about replacing them in the next few years as they were going to expire soon. He explained he's just a service guy and not an estimator, so no sales tactics here - which I appreciated, especially after the whole Advanpro scenario. He fixed the igniter issue and went on his way. Both furnaces are still working great and I'm glad I came to my senses. I feel as though I was bullied and taken advantage of because I'm a single woman. PLEASE BEWARE OF THIS COMPANY!!!! Go with your gut and ALWAYS get a 2nd, 3rd and 4th opinion!
