Advance Robotic Duct Cleaning

If anybody is looking for a furnace and duct cleaning company do NOT call this one. After they cleaned my furnace it wouldn't turn on and Tradesman Mechanical had to be called. They found that the fasteners weren't put back on the furnace cover properly. Advance Robotics has now accused me of tampering with the furnace to get the cleaning free. They scratched my floor, I was told to shut up by a crew member and the list goes on. They take no responsibility and say they aren't to blame.
