If your brand-new air conditioner is not cooling well, it can be frustrating. But in most cases, the issue is not a defect—it's usually due to installation, settings, or airflow problems rather than the machine itself.
Here are the most common reasons and fixes.
⚙️ 1. Improper Installation (Most Common Issue)
Even a high-quality AC will underperform if installation is not done correctly.
Common mistakes:
- Incorrect gas charging
- Poor copper pipe insulation
- Indoor and outdoor units placed improperly
- Leakage in refrigerant line
👉 Fix: Always get installation done by authorized technicians from brands like
Voltas Limited, Blue Star Limited, or lg Electronics service centers.
🌡️ 2. Wrong Temperature Settings
Many users set unrealistic expectations.
Issues:
- Setting temperature too high (like 26–28°C expecting instant cooling)
- Using “Fan mode” instead of “Cool mode”
- Eco mode limiting compressor power
👉 Ideal setting: 24°C to 26°C for normal cooling
🌬️ 3. Airflow Blockage
Cooling depends heavily on proper airflow.
Problems:
- Dirty air filters
- Blocked indoor vents
- Furniture blocking airflow
👉 Fix:
- Clean filters every 15–20 days
- Ensure free airflow around indoor unit
🔥 4. Room Heat Load Too High
If the room is too hot, the AC struggles initially.
Reasons:
- Direct sunlight through windows
- Poor insulation
- Too many heat-producing devices
👉 Solution:
- Use curtains or blinds
- Close doors and windows tightly
- Reduce heat sources in the room
⚡ 5. Low Refrigerant Gas (Gas Leakage)
If cooling is weak even after hours:
Signs:
- AC runs continuously but doesn’t cool
- Ice formation on pipes
- Weak airflow
👉 Fix: Call technician for gas check and refill.
🧠 6. First-Time Operation Delay
New ACs sometimes take time to stabilize.
- Initial cooling may feel slow
- System adjusts after a few cycles
- Outdoor unit heat release affects performance
🧾 7. Electrical or Voltage Issues
Low or unstable voltage can reduce compressor efficiency.
👉 Use:
- Stabilizer (if required)
- Proper dedicated power line
📝 Final Thoughts
If your new AC is not cooling properly, the issue is usually installation quality, airflow, or settings—not the product itself. A quick inspection of these factors can often solve the problem without expensive repairs.
