After his service in the U.S. Army, David moved back to his home state of Oregon to work as head technician at a Portland based HVAC cleaning company for several years. Having family in Central Oregon, and a love of sunshine, lakes and the mountains, David moved to Bend in the winter of 1998 to launch Guarantee Air Duct
Cleaning.
Due to dissatisfaction with the cleaning results provided by existing cleaning equipment, David designed a new duct cleaning system and launched RamAir International, Inc. in 2007 to manufacture the innovative equipment. He began using his RamAir system at Guarantee Air Duct Cleaning and was immediately met with rave reviews, which caught the attention of some of the country’s leading cleaning experts and led to international adoption of the technology. Today, David is considered one of the world’s leading experts in HVAC duct cleaning and restoration, with users of his system in every major city of the United States and 21 foreign countries.
In addition to actively running Guarantee Air Duct Cleaning in Bend, Oregon, David travels the world training professionals on the process of HVAC crime scene remediation, disaster restoration, meth and fentanyl decontamination and bioterrorism response. Companies travel from around the world to train at his facility in Bend, Oregon, and the top industry publications and organizations turn to David for information on these topics.
