What to do if my air conditioner’s temperature is not cool enough?
What to check?
Samsung's air conditioner is designed to be outstandingly efficient. The fast-cool mode provides a rapid change in the air temperature to quickly drop the room temperature to your designated setting. If you notice that the temperature of your air conditioner is wrong even though you set the proper settings, it is recommended for you to check the following environmental conditions.
1. Adjust the temperature settings
- When you feel the temperature of the air conditioner is not cool enough, check to make sure the selected temperature is set to low.
- Press the + or - of the Temp button to change the temperature of the air conditioner.
- The room should be heat-shielded well with all the doors and windows closed; otherwise, it may cause poor cooling performance.
2. Clear the obstacles around the air conditioner
If there are obstacles placed in front of the indoor unit or outdoor unit, it may cause the air conditioner to become inoperative. (Product is unable to draw in sufficient air.)
3. Consider the space capacity
If the room size is bigger than the capacity of the air conditioner, it will take more time to bring the temperature down. Therefore, it is recommended to use an air conditioner that fits your home area. If you use an air conditioner that has insufficient capacity compared to the area of the house, the house may not be cool, and it will result in a high electric bill.
4. Check the air filter
When the inside air filter has too much dust, your air conditioner is unable to draw in a sufficient amount of air. This may be the cause of the issue with the temperature. We recommend you to clean the filter every 2 weeks or when the CF display code appears on the indoor unit display. (The CF display code means filter-cleaning reminder)
Please check your air conditioner model below and follow the how-to guide to clean the air filter. This will give you cool and fresh air.
Note:
- Find the user manual for details for the filter detach and assemble methods. (It may differ among the various models.)
- Cleaning time frames may differ depending on the usage and environmental conditions.
Step 1
Slide the filter off of the unit.
Step 2
Use a soft brush or vacuum cleaner to remove any dust or debris on the filter.
Step 3
If the filter has a lot of dust, soak the filter for about 30 minutes in soapy water and then rinse it.
Step 4
After rinsing the filter, dry it in a well-ventilated area.
Step 5
Reinstall the filter.
Note:
- Do not scrub the air filter with a hard-bristled brush or other rough cleaning tool.
- If the air filter is not dried completely or is dried in a confined (or humid) area, a bad odor can occur.
- Do not expose the air filter to direct sunlight when drying it.
If your air conditioner is a floor standing type with an inverter, check the following steps outlined below. The inverter floor standing model has two types of filters.
- Full HD filter: It filters out the large particle dust of the incoming air.
- Zero filter: It traps small dust particles within the air. It is washable and can be used semi-permanently.
