What does EER mean?
EER is the Energy Efficiency Ratio, which is determined by U.S. Government standards and tests. The higher the EER number, the more energy-efficient the unit. According to Federal laws, all air conditioners must have the EER listed on a bright yellow tag attached to every unit. All air conditioners feature an EER of 8.0 or higher. The EER of a unit is calculated by dividing the number of BTU’s the unit is rated for, by the number of watts the unit uses.

What is a BTU?
A BTU, or British Thermal Unit, is the amount of heat it takes to raise the temperature of 1 pound of water 1 degree Fahrenheit. BTUs are used to rate air conditioners in order to help determine the correct application for your needs. 

How important is room size when deciding what air conditioner is right for me?
Too large a unit will cause your air conditioner to "short cycle", shutting off before removing the humidity from the air. Too small a unit will run continuously and never achieve maximum efficiency.

What is the proper setting to cool my room?
For correct cooling operation follow these simple steps:

1. Close Air Exchanger, if provided.
   
2. Turn the thermostat to the maximum.
   
3. Turn master control to "HI COOL".
   
4. If the room becomes too cool for comfort, turn the thermostat counterclockwise until the compressor turns off. The air-circulating fan will remain in operation.
   
5. When the desired comfort level is reached, the Master Control may be turned to a lower setting.

          Caution: If the air conditioner is shut off, wait a minimum of three minutes before restarting.

How can I help my unit work at peak efficiency?

1. Close fireplace dampers, windows and doors. Seal the opening to the attic or other un-cooled areas.
   
2. Install awnings, keep shades and curtains closed to keep out the heat and sunlight.
   
3. Install the air conditioner where its exterior parts will be shaded.
   
4. Insulate, particularly the attic floor. Have the attic well ventilated.
   
5. Use storms windows and doors or insulated glass. Weather-strip the doors and windows.
   
6. Use a higher (warmer) thermostat setting during peak periods or when the area is not occupied.
   
7. Don’t let heat build up all-day and then try to cool areas quickly. Start the unit earlier in the day and cool areas slowly before they become occupied.
   
8. Avoid activities such as baking and the operation of a self-cleaning oven while using your air conditioner during the high heat times of the day.
   
9. Do not block the back or the outside of the unit.
   
10. Change or clean the filter regularly. Check the airflow for blockage by outside obstructions.
    
11. Take care of the unit by having it checked and cleaned by a qualified technician at the start of every season.
    

How often should I clean my filter?

Clean your filter every two weeks in most environments. If there are smokers or heavy cooking present, once a week would be advised.

1. Turn the Master Control off.
2. On most units, lift up on the two filter tabs at the top of the decorative front panel. The hanging filter should slide out easily. On some units the decorative front panel may need to be removed with a screwdriver. Please check your owner’s manual for the model you have purchased.
3. Carefully wash the filter with warm water and mild detergent. Rinse with clear water, allow to dry and replace.
4. Replace filter in decorative front.
5. Return Master Control to desired operation.
