Troubleshooting
You can solve many common air conditioner problems easily, saving you the cost of a service call. Try the suggestions
below to see if you can solve your problem without outside help.

The power supply

Air conditioner seems to run too much

Check if . . .
The current air
conditioner replaced
an older model.
Then . . .
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 appli-
antes during the hottest part of the day. A higher capacity air conditioner may be required
depending on the size of the room being cooled.
