Of all the inventions of the last few centuries, the development of the air conditioner might just be the greatest. In fact, the inventor of the first electromechanical cooling system, Willis Carter, should probably be considered for sainthood. The folks at AC Wholesalers might be in the running as well. They sell a huge variety of air conditioners, fans, ventilation devices and refrigeration supplies at some of the lowest prices on the internet. In fact, they've got 25-50% off the biggest brands in the business, including Amana, Delta, LG, Daikin and Honeywell.
