US Airconditioning Distributors is the world's largest privately owned HVAC distributor. They sell more environmentally-friendly air conditioning units than any other independent distributor in the country.

In addition to encouraging the sales of environmentally friendly products, they also do everything possible to save the environment within their own day-to-day operations. US Air Conditioning produces almost 100% of the required electricity for their main 250,000 sq ft location in the City of Industry, California with one of the largest solar cell arrays in the U.S. At 850 KW it produces enough electricity to power over 400 homes. In addition they have their our own natural gas fueling station and 24 clean-burning natural gas trucks, which produce only 5% of the emissions of a diesel truck of the same size.
