We have a Carrier furnace and found out from Carrier that there was a warranty with Aire One. I called to confirm and was told he would look into it. I got a call back saying, yes, we have the parts and labor warranties, but that I would need to pay $90 for the diagnostic fee, which I agreed to. The technician firstly did not show up at all or call the day he was supposed to. I was given a 2-4pm window and there was zero communication. I called the next day several times and finally reached someone who booked him again to come. After showing up late, he did the diagnostic and THEN told us we actually do NOT have a labour warranty, as the previous owner did not perform any maintenance. He also charged $99 instead of the quoted $90. When I called the head office, they confirmed we only had a parts warranty, which I indicated I should have been told from the start, as I wouldn't have wanted to deal with them after the missed appointment. We then booked another appointment for the installation of the parts. I was told 9-11am. By 12pm, I had seen and heard nothing and called. The technician eventually called me to say he was coming at around 1:30pm. I had an appointment that could not be moved at that time, so I told him to come after 3pm and he agreed. At 2pm he showed up at our house! When I arrived home at 2:30 he came in and told me actually you don't even have a parts warranty, since we're not the original owners. At that point I was beyond frustrated with the misinformation at every step of the process (and never received the question of whether we are the original owners), so I asked them to leave. I do not recommend dealing with Aire One, first and foremost, because you cannot trust anything you are told.
