The current air conditioner replaced an older model	The use of more efficient components may cause the air conditioner to run longer than an older model, but the total energy consumption will be less. Newer air conditioners do not emit the “blast” of cold air you may be accustomed to from older units, but this IS NOT an indication of lesser cooling capacity or efficiency. Refer to the efficiency rating (EER) and capacity rating (in BTUs/hr.) marked on the air conditioner
The air conditioner is in a heavily occupied room or heat- producing appliances are in use in the room.	Use exhaust vent fans while cooking or bathing and try not to use heat-producing appliances during the hottest part of the day. A higher capacity air conditioner may be required depending on the size of the room being cooled.
