Duct Cleaning Masters

Rowan did an excellent job by himself. He arrived on time and explained the whole process including the portable vacuum he brought. The only thing I noticed was he was only covering the vent/register he was blowing with compressed air; the other vents were left open. This is not what other duct cleaners do. I called his attention to this and he said there's no need for it. Altogether, he spent more than two hours in cleaning my ducts, both the supply and return ducts. Would hire Duct Cleaning Masters again.
