Air Conditioner - Hot Outdoor Temperatures
There is no maximum temperature limitation for operating room air conditioners. If you live in an area where daytime temperatures can reach 120 degrees Fahrenheit, make sure the room air conditioner is sized properly. In extremely high temperatures such as this, a room air conditioner will improve indoor air temperatures approximately 15 to 20 degrees.
Local air conditioner dealers in these areas can also offer advice for purchasing the proper air conditioner for use in the high temperature region.
