use in the room.
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 BTUsihr.) marked on the air conditioner.
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.
