Aire One (Aire One) Heating & Cooling

My Central AC was originally installed by Aire One by the first owners of the property. The unit is still under warranty as the documents say it has 10 years warranty. So I called them up to make an appointment to check why my AC is not cooling my house. When the technicians arrived, they first checked the outside AC unit. I asked if it was low on freon due to leak and they confirmed it was fine and nothing is wrong with it. So they proceeded to my basement and opened up my furnace/AC. They said that I need to replace my furnace motherboard that controls the AC blower. They mentioned that my AC was not cooling/blowing any cold air because the blower is not turning on when I turn on my AC on cooling. Note, they didn’t even use a multi-meter to confirm if the board is in fact faulty. They left after about 20 minutes and told me to make an appointment to replace the “Bad Control Module”. When I got a call back from their boss, he quoted $650 + taxes to replace the board and labour. He also mentioned that that part is not under warranty and only the compressor is. I was shocked how much it was as I already paid the diagnostic fee of $99+ taxes already. So I decided to wait and get a second opinion as I didn’t want to blow that much money. I had another company come by and they found out that the freon was leaking and blocked heating duct intakes(My Fault). They even checked the board with a multi-meter and confirm there’s absolutely nothing wrong with the control board.
