I found my furnace stopped working and looked into it for approximately 2 hours before I made a call to Aire One last night. They were quick in scheduling an on-site check by their service tech and he did show up in the window we set up. After he checked my furnace, he said it might be the vent motor that needs to be replaced. Then there are a few other options he offered, including a furnace replacement or a complete package (AC + furnace). Since the service tech didn't tell me too much of the condition of my furnace (just moved in for a couple of months), so I wasn't sure what to do with it. However, their regional manager followed up with me within a day after his visit to talk about my situation and offered the best he can do. Now my furnace is back and running well. The Aire One in KW is very well managed and I think I know why people had a very good review for it. I would still considering calling them or refer them to my friend in the future.
