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/h) marked on the air conditioner.
  • The air conditioner is in a heavily occupied room, or heatproducing 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. Portable air conditioners are designed as supplemental cooling to local areas within a room. A higher capacity air conditioner may be required, depending on the size of the room being cooled.
