Before starting his own ductwork cleaning business, Larry worked 26 years installing furnaces and air conditioning for one furnace company in Des Moines, Iowa. At one time he worked for a furnace company that owned a vacuum truck - their main reason for having it was to get a foot in the door to sell furnaces, ac, electrostatic filters, etc. Our only job is cleaning ductwork - not selling anything - just doing the best job possible. In the beginning we used the procedure taught by the company where we purchased our truck and equipment. Larry used his HVAC experience over the first few years to change and improve our cleaning process... testing different methods until we developed our current method which we have used for over 15 years now. This method was designed and is used exclusively by Gilliam Power Vac.
