Alberta Furnace Cleaning (Calgary)

Sharing our experience with Alberta Furnace Cleaning. We live in a townhouse so the technicians asked if they could come in the back. I told them to park in the visitor stall and drag hoses through the gate. They decided to go through garage without asking me. I just waited until they were done, paid them and went to my car. It was covered in a black greasy soot, then I looked at the white soles of my shoes also black and making tracks on the floor.Bins covered in black so I started sweeping. This is the pile I got from half of the garage.The black stuff is from the diesel truck that was left idling outside the garage. EVERYTHING we touch in there is covered in greasy soot. Sam in Customer Relations at Alberta Furnace Cleaning says it is the fault of the manufacturer of the truck and refuses to help us get this mess cleaned up.
