Well, it looks like Affordable Squeaky Clean got a poor review from a customer in the past, BUT my experience today was "five-star excellent." If you, your children or that special someone have allergies like I do, then at least twice a year you should have all your vents and registers professionally cleaned for dust-mites and other pollutants. Not only was Affordable Squeaky Clean the least expensive, but the price did not compromise the quality of work provided. I am extremely pleased with the serviced provided today. Also, got the dryer vent thoroughly cleaned at the same time, which can become a fire hazard if not cleaned at least once a year depending on how much you use it. Thumbs - up to Affordable Squeaky Clean!
