The Air Conditioning Contractors of America (ACCA) is the largest air conditioning contractor in the United States. The American Society of Heating, Refrigerating, and Air-Conditioning Engineers (ASHRAE) is also another organization that licenses air conditioning contractors.

ASHRAE stands for American Society of Heating Refrigeration and Air conditioning Engineers.

I believe the urea eutectic mix as well as those for several other salts are listed in the ASHRAE (American Society of Heating, Refrigerating, and Air-conditioning Engineers) Handbook. http://www.ashrae.org/

Not only does Home Depot carry both heating and air conditioning units, they also offer experienced installation to make things easier for you. They offer high-quality heating, air conditioning, and heating-air conditioning units in their heating department.
