I would like a price range on air conditioners that fit in a window. I would like to purchase at lease 75 to 100 window a/c to give away. Where do I look for it? When I searched it kept wanting to give me a quote for an HVAC A/C installation.

If you want to buy that many for charity, contact a manufacturer and ask them about supporting you. Currently, you could inquire with a retailer about partnering with you, for some recognition in return.

It will depend on the BTU rating. The cheap ones (8,000 BTU) are $220. The high end ones (24,000 BTU) are $700. There are middle range options for $300 to $400 each. Walmart has a 5,000 BTU option for $135.
