My furnace broke down on a Saturday in March so I called up Max and he answered right away. He was able to come to my house the same day. He opened up my furnace and told me that my motherboard was dead. He did not pressure me at all to buy any fancy new furnaces but warned me that after he replaces the motherboard, there could still be other issues because there were signs of water damage. Because the part supplier was closed on the weekend, he said he can get me the board on Monday if I wanted. I decided to do a bit of research on furnaces since I didn't know anything about them and was still undecided. I called up Max and he answered all my questions. Again, he did not pressure me into any fancy new furnace but he said if I did want one, he recommended a 1 stage furnace for my house as 2 stage furnaces have shorter life spans and are more costly to repair. In the end, I decided to go with the motherboard repair and he showed on Monday with the new board like he said he would. He replaced the board and the furnace was up and running. He then investigated the rest of the system and discovered that the drainage pipe from the humidifier was blocked and it was pushing water back into my furnace. It seems that I had 3 drainage pipes that merge into one so water was being pushed back into my furnace. He told me that the air con, humidifier, and furnace should have separate drainage pipes so that it won't impact each other if something goes wrong. He installed 3 new pipes as well and the furnace has been running smoothly since. He's a nice guy and patiently answered all my questions. I would use Aire Max again!
