Troubleshooting AC remote & thermostat issues
1. Why Is My AC Not Cooling Properly?
If your air conditioner is running but not cooling, check these common reasons:
1.1. Dirty or Clogged Air Filters
Problem: Dust and dirt block airflow, reducing cooling performance.
Fix: Clean or replace the air filters every 2 weeks for better airflow.
Pro Tip: If you live in Dhaka or a dusty area, clean your filters weekly for best results.
1.2. Low Refrigerant (Gas) Levels
Problem: If your AC is blowing warm air, it might be low on refrigerant gas.
Fix: Call a professional to check & refill the refrigerant gas.
Pro Tip: If your AC needs frequent gas refills, there might be a leak that needs to be fixed.
1.3. Blocked Condenser Coils
Problem: Dust and debris block the outdoor unit, making it harder to cool.
Fix: Clean the condenser coils with water or a soft brush.
Pro Tip: Keep the outdoor unit in a shaded area to improve cooling efficiency.
1.4. Incorrect Temperature Settings
Problem: Your AC is set to fan mode instead of cooling mode.
Fix: Check the remote settings and make sure the mode is set to ‘Cool’.
Best Temperature Setting for Bangladesh: 24-26°C for best cooling & energy savings.
1.5. Faulty Compressor
Problem: If your AC runs but doesn’t cool, the compressor might be broken.
Fix: Contact customer service if your AC is still under warranty.
Best Brands with Long Compressor Warranty: Haier (12 years), Gree (10 years), Midea (10 years).
2. AC Leaking Water – What to Do?
Water leaking from your AC is a sign of a clogged drain pipe or frozen coils.
2.1. Clogged Drain Pipe
Problem: Dirt blocks the drainage pipe, causing water to overflow.
Fix: Use a vacuum cleaner or blow air through the pipe to unclog it.
Pro Tip: Clean the drain pipe every 3 months to prevent blockages.
2.2. Frozen Evaporator Coils
Problem: If your AC is leaking & not cooling, the coils might be frozen.
Fix: Turn off the AC for 2-3 hours to let the ice melt, then restart it.
Prevent Freezing: Don’t set the AC temperature below 20°C for long periods.
2.3. Incorrect AC Installation
Problem: If your AC is tilted incorrectly, water can leak indoors.
Fix: Adjust the angle so the water drains outside properly.

3. Fixing AC Remote & Thermostat Issues
3.1. AC Remote Not Working
Problem: Your remote is not responding to the AC.
Fix:
Replace the batteries (use fresh AA or AAA batteries).
Clean the remote sensor (wipe it with a dry cloth).
Point the remote directly at the AC unit and try again.
Pro Tip: If the remote still doesn’t work, use a universal AC remote or mobile app (if your AC supports WiFi).
3.2. Thermostat Not Working Properly
Problem: Your AC runs but doesn’t stop or cool properly.
Fix:
Make sure the thermostat is set to cool mode.
Reset the AC (Turn it off for 5 minutes and restart).
Pro Tip: If your thermostat is damaged, contact official customer service for replacement.
