Your new air conditioner is designed to give you many years of dependable service. This section tells you how to clean and care for your air conditioner properly.
Cleaning the Air Filter
The air filter is removable for easy cleaning. A clean filter helps remove dust, lint, and other particles from the air and is important for best cooling and operating efficiency. Check the filter every 2 weeks to see whether it needs cleaning.
NOTE: Do not operate the air conditioner without the filter in place. Cooling performance will be effected when the coil becomes dirty.
Use a vacuum cleaner to clean air filter. If the air filter is very dirty, wash it in warm water with a mild detergent and rinse well.
NOTE: Do not wash the air filter in the dishwasher or use any chemical cleaners; it may damage the filter. Air dry the air filter completely before replacing to ensure maximum efficiency.
Remove the air filter
Remove the filter by grasping the tab on the filter and pulling it out of the grille to the side.
Reinstalling the air filter:
Slide the filter back into the grille.

If you experience | Possible Causes | Solution |
Air conditioner cycles on and off too much or does not cool room in Cooling mode | Air conditioner seems to run too much. | 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 air conditioners, 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 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. | |
Airflow is restricted. | The louvers are blocked. Install the air conditioner in a location where the louvers are free from curtains, blinds, furniture, etc. | |
The temperature control may not be set correctly. | The temperature setting is not set to a cool-enough setting. Adjust the cooling mode and/or thermostat to a cooler setting. | |
The air filter is dirty. | The filter is dirty or obstructed by debris. Clean the filter. | |
The room may be too warm. | Allow extra time for the air conditioner to cool off a very hot room. | |
| The air conditioner is not properly sized for your room. Check the cooling capabilities of your room air conditioner. Room air conditioners are not designed to cool multiple rooms. | |
| There is excessive heat or moisture (open container cooking, showers, etc.) in the room. Use a fan to exhaust heat or moisture from the room. Try not to use heat-producing appliances during the hottest part of the day. | |
| Windows or doors to the outside are open. Close all windows and doors. | |
Cold air is escaping. | Check for open furnace registers and cold-air returns. | |
| Windows or doors to the outside are open. Close all windows and doors. | |
The cooling coils are frozen. | The inside evaporator and outside condenser coils are dirty or obstructed by debris. | |
| The outside temperature is below 65°F (18°C ). Do not try to operate your air conditioner in the cooling mode when the outside temperature is below 65°F (18°C). This reduces the risk of freezing up or damage to the unit. | |
The air conditioner is freezing up | Ice blocks the air flow and stops the air conditioner from cooling the room. | Set Mode dial to high fan or high cool and set Temp dial to 1 or 2. You may have to turn off the air conditioner to allow ice to thaw before using. |
Water is dripping outside | Hot and humid weather. | This is normal. |
Water is dripping inside the room | The air conditioner is not properly leveled. | For proper water drainage, make sure the air conditioner is slightly tilted downward toward the outside. NOTE: Do not drill a hole into the bottom of the metal base and condensate pan; doing so will reduce cooling performance. |
Water collects in the base pan | Moisture removed from the air is draining into the base pan. | This is normal for a short period in areas with low humidity and normal for a longer period in areas with high humidity. |
