Curative Heating & Cooling Inc

I found these guys on kijiji and they came over for ac repair, it wasn't cooling. The technician told me it would cost $370 to get it working again. After the work was done I didn't see any change in the cooling, so I called them back at which point he tells me that its the AC and that's the best it could do. I specifically asked him before getting the work done that this would fix it and now he wanted another $400 and wasn't sure if that would fix the problem as well. I would suggest stay away from these guys, they don't know what they are doing.
