For a standard 2,000 sq ft home in Audubon, expect to pay between $350 and $550. This includes cleaning all supply and return vents, the main trunk line, and a sanitizing treatment. We avoid nickel-and-diming by including everything in one upfront price—no surprises.
Absolutely. Audubon’s summer humidity breeds mold and mildew in ductwork, circulating allergens like pollen and dust mites throughout your home. A thorough cleaning removes these contaminants, reducing allergy flare-ups and improving indoor air quality.
Yes! We proudly offer a 10% discount to Audubon seniors (65+) and active/retired first responders. Simply mention it when booking—we verify eligibility on the spot and apply the savings immediately.

Late fall or early spring is ideal. Fall prepares your system for winter heating, while spring removes winter’s dust and allergens before allergy season peaks. Avoid summer—our schedule fills fast with humidity-related emergencies.
We clean both! Clogged dryer vents in Audubon homes are a fire hazard and reduce efficiency. Our service includes removing lint buildup from the vent line, duct, and exterior exhaust—saving you money and reducing risk.
