Hampton Bay is a product line sold exclusively through Home Depot.  Today, the brand encompasses fans, ceiling fans and lighting products.  At one point, LG manufactured  the air conditioners for Home Depot to be sold under the private label Hampton Bay.  Original model numbers included HBLG -Hampton Bay Life’s Good.  At some point, Home Depot discontinued the air conditioning line of products but carries LG brand air conditioners among others.  Some replacement parts are available via various online vendors but not through Home Depot.
