About Guarantee Air Duct Cleaning

Central Oregon's Leading Duct Cleaning Business

Guarantee Air Duct Cleaning

Servicing Bend, Oregon since 1998

Guarantee Air Duct Cleaning founder and owner, David Hart, founded Guarantee in 1998 after working at the largest air duct cleaning company in Portland, Oregon as lead technician and instructor. Since founding the business, he has grown it to service residential homes in Central Oregon and large commercial facilities throughout the West Coast.
David is the inventor, designer and manufacturer of the globally acclaimed RamAir ClearView Duct Cleaning System, a revolutionary game-changer in the air duct cleaning industry. A unique, brushless duct cleaning system, RamAir is designed to protect the integrity of your ductwork, while producing unrivaled results, and allowing both the technician and customer to see the dust and debris that’s being removed as it’s being removed. This visual factor provides several benefits. In addition to showing the dust, debris and garbage as it is being removed (through a clear, sealed port), it affords a clear view of when the process is complete, removing the guesswork that plagues traditional duct cleaning methods.
