Where can you buy a room air conditioner?

Both Home Depot and Lowe's offer room air conditioners. The stores offer different models of room air conditioners, from portable units to those that are meant to be installed in a window.

As of 2015, Home Depot's website arranges the selection of home air conditioners so users can find room air conditioners that are meant to cool different size rooms as well as those that are different kinds of units. Lowe's has more of a list format when it comes to searching for room air conditioners, including Energy Star qualifications, BTU ratings, cooling capacity options and brands as filters to narrow the product search.
