It is critical that the capacity of a room air conditioner be the right size for the room being cooled. An improperly-sized air conditioner can result in a cold, clammy environment or an inadequately cooled room. An oversized air conditioner results in the compressor running for short periods of time. As cold air leaves the air conditioner in a small room, it is deflected off of the walls back to the air conditioner and prematurely cycles the appliance off. This results in cold spots and hot spots and very little loss of humidity. An undersized air conditioner results in the compressor staying on most of the time and the appliance not adequately lowering the humidity level and temperature in the room. Ambient indoor and outdoor temperatures can be an issue as well. Operating a room air conditioner if the outdoor temperature is 70° F or below will limit the cooling capacity of the unit. Check the indoor temperature. If the room is already 64° F or below, the thermostat cannot turn on the compressor. Consider the temperature of the room when the air conditioner was first turned on. If the room was very hot, it will take longer to cool the room. When heat is stored up in walls, furniture, rugs and draperies, it will take longer to cool the room down. Whenever possible, turn the unit on before the room heats up. If there is ice on the coils, the outdoor temperature may be below 70° F. The best way to prevent ice on the coils is to avoid running the appliance if the outdoor temperature is below 70°F. If the temperature is close to 70 or you are unsure of the temperature, you can turn the thermostat to a warmer setting and set the fan switch to the highest position. If the cooling performance continues to be an issue, check with the retailer from whom you purchased the unit to return it for an exchange or call our service team Bodewell at 1-833-4Bodewell to discuss your options under the limited one-year warranty.
