Our Name Is On The Line . . . "Thats Why We Are So Good"

Earth City Distributing was founded in 1976 by Carl Langendorf.


Carl retired from Janitrol Heating and Air Conditioning in 1968, where he was National Sales Manager. At that time, Carl, along with his business associates, Ed Gaus and Len Scott of the Gaus-Scott Company, purchased the Yelton Supply Company, the Janitrol distributor and renamed the company Langendorf Supply (Division of Gaus-Scott).


The company rented office/warehouse space in one of the few new buildings located in Earth City, MO at that time. Seeing the potential in the Bard Wall Mount air conditioner, Carl sold the company in 1975 to his employees and started a sales rep company named Earth City Distributing. Carl and Len Scott were the only two employees selling Empire gas unit heaters, grilles and registers, refrigeration supplies and Bard air conditioning products.


Carl pioneered the Bard Wall Mount units with the telecommunication industry.  At one point Carl had sole responsibility for all telecommunication applications in the nation.


Today, Earth City Distributing not only pursues the Bard Wall Mount business, but is specializing in the vertical unit ventilator school market. ECD is one of the largest distributors in the country marketing the Bard Q/Tec Water Source Heat Pumps.


Since 2005, we have placed the Q/Tec product in over 60 schools in Illinois and Missouri. This equipment is known for its quality, low sound level and efficiency.  ECD is known for its outstanding service.


To expand from the offering of Bard Wall Mount air conditioners and the Q/Tec line, Earth City Distributing is aggressively marketing complimentary products that focus on energy savings and clean air.  Take a peak at the other products we offer.  other products


Today, Earth City Distributing continues to operate with one goal in mind: Delivering quality products that increase IAQ utilizing the highest ethical and moral standards.
