Is your Samsung air conditioner not cooling? Learn how to fix no cooling or optimum cooling issues by checking settings, cleaning filters, ensuring proper installation, and matching AC capacity to room size.

Here are the steps to fix the no cooling issue in your Samsung air conditioner

Below are the possible causes of slow cooling in Samsung air conditioners:

1. Incorrect Cooling Mode Settings:

Ensure the cooling mode is set to a lower temperature for optimal cooling.

2. Dirty or Clogged Filters:

Clean the air filters every 2 weeks to maintain proper airflow. Blocked filters can reduce cooling efficiency.

3. Room Insulation:

Shield the room from external heat sources to improve cooling performance.

4. Block Direct Sunlight:

Use curtains or blinds to block direct sunlight entering the room, which can increase heat.

5. Mismatched AC Capacity and Room Size:

Ensure the AC capacity matches the room size. As a general rule:

  • 1 Ton = 100 Sq Ft
  • 1.5 Ton = 150 Sq Ft
  • 2.0 Ton = 200 Sq Ft

6. Improper Installation Location:

Avoid installing the AC on the corner or side of the room, as it may not distribute cool air evenly.

7. Outdoor Unit Exposure:

Direct sunlight during peak summer can heat the outdoor unit, reducing efficiency. Place it in a shaded area.

7. Regular Maintenance:

Schedule timely servicing of your AC to ensure it operates efficiently and avoids cooling issues.

If the problem persists, consider contacting Samsung customer support for professional assistance.
