Still sweating even with your LG air cond on full blast?
Let’s fix that. Here are the top 5 reasons your house feels panas—and how to get it sejuk again.
🧊 1. Dirty Air Filters Block Cool Air
Problem: Dust and dirt clog up your air cond filters, stopping airflow.
Result: Your LG air cond works harder but cools less.
✅ Quick Fix: Open the front panel Remove the filter Wash it gently every 2–4 weeks
Pro Tip: A clean LG air cond = faster cooling and lower bills.
💨 2. Low or Leaking Refrigerant Gas
Problem: Refrigerant is what makes your LG air cond cool.
Low gas = warm air.
Result: You’ll feel the fan blowing, but no cold breeze.
✅ Quick Fix: Call a certified LG technician Don’t DIY—this needs proper tools and safety checks Low gas is not normal. It often means there’s a leak.
3. Wrong Size Air Cond for Your Room
Problem: If your LG air cond is too small for the room, it can’t cool effectively.
Result: It runs non-stop but never reaches the right temperature.
Room Size Guide:
< 150 sq ft —1.0 HP
150–250 sq ft —1.5 HP
> 250 sq ft — 2.0 HP+
Bigger room = bigger cooling power needed.
☀️ 4. Bad Room Insulation
Problem: Hot sun, thin curtains, and leaky windows cancel out your LG air cond.
Result: Cool air escapes, hot air stays in.
✅ Quick Fix: Use blackout curtains Seal gaps in doors/windows Close unused doors to trap cool air Your LG air cond cools better when your room works with it, not against it.
🎛️ 5. Wrong Remote Settings or Faulty Thermostat
Problem: Sometimes it’s not the machine—it’s the settings.
Result: The fan runs, but no actual cooling happens.
✅ Quick Fix: Make sure it’s on cooling mode (snowflake icon ❄️) Set temperature to 23–25°C
Check if thermostat is responsive Double-check your settings before calling for help.

Even the best air cond won’t perform if it’s ignored. LG units are built to last—but they need regular care.
