Air conditioner
seems to run too
much
■Is there a door or window
open? Keep doors and windows closed.
■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
BTU/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.
