For generations, fresh air has been the folk cure for many maladies. The technicians at Choice Green Clean aim to deliver fresh air to their customers without ever needing to step outside. They specialize in air-duct and dryer-vent cleaning, banishing the clots of dust and allergens that clog the air-circulatory systems of many homes and offices. While digging out debris, they also inspect machinery, making sure that every pump is pumping, every screw is tightened, and every wire still responds to the nickname Sparky. In addition to air-cleaning services, they also keep floors fresh by steam cleaning carpets with eco-friendly cleansers that are nontoxic and hypoallergenic.
