Sunlight shines on a shiny wooden floor in an empty room, while a room air conditioner keeps things cool. Hot summer days and muggy nights can be uncomfortable, which is why many people install room air conditioners.
A window air conditioning unit is placed in the window of a home, ensuring cool air for the rooms inside. On a hot, humid day, the interior of a home can be transformed with a mere push of a button.
Public health officials warn residents to keep indoors with the windows shut, to set air conditioners to run on recirculated air and to use air purifiers if possible.
