He came to clean my duct, I ended up working more than him to make sure the job was done properly, and one of the motor of his vacuum was not working so it was pushing back all the dust in the house...

Ended up having to call another company to take care of the issue I paid him to fix. Robin seems like a nice enough guy, but if you're looking for someone who listens to your concerns and sees things through to the end, I suggest you keep looking.
