The optimal check timing
The AC rests all winter, then suddenly runs in June. With dust piled up, refrigerant low, never once checked. One round of care before summer protects your bill, repair costs, and health all at once.

1
Cut the power — the remote alone isn't enough
An AC turned off by remote still has current flowing. Unplug the wall outlet, or flip the breaker.
⚡ Cleaning inside while powered risks electric shock
2
Open the front panel — lift up or release the side buttons
Most open by lifting upward. For stand models, pull the handle to detach the front cover.
๐ธ A photo before removal makes reassembly easy
3
Take out the filter — it detaches easily as a mesh
The moment you pull it out, you see how much dust has piled up. A 1-year-old filter is pitch black. This blocks cooling and wastes electricity.
๐ก Vacuum the dust off first to speed up washing
4
Rinse with water — no detergent, medium shower pressure
Detergent damages the filter material. Lukewarm water is enough. Spray from the back (not the air-intake front) to flush dust out well.
๐ฟ High pressure tears the filter mesh. Use medium strength
5
Dry fully in shade — at least 1~2 hours
A dryer or direct sun deforms the filter. Natural drying in shade is best. Fitting it before fully dry breeds mold inside.
☀️ Clean on a clear morning and you can fit it that afternoon
6
Test-run after fitting — check cool air and noise
Run 10 minutes after fitting to check for odd noise or dripping water. You'll feel the cool air is stronger than before.
✅ Repeat every 2 weeks and both your bill and lifespan improve

② 6 tips to save on your bill
Beyond filter cleaning, just changing how you use it changes your bill.
26~28°C setting is the answer
Lowering below 24°C cools at the same speed but uses twice the electricity. At 26°C with a fan it feels like 23°C.
Savings: ~7% per 1°CUse with a fan
AC + fan uses less electricity than AC alone. The fan circulates cool air so you feel the same coolness set 2~3°C higher.
Savings: 15~20% of total billUse a sleep timer + sleep mode
Once asleep, body temperature drops and you don't need a low temperature. Set a timer to shut off 1~2 hours after bed, or use sleep mode (auto temperature rise).
Savings: 40% off nighttime billDry mode is cooler than cooling
In the rainy season, humidity feels hotter than temperature. Then use DRY mode instead of COOL — less electricity and more comfort.
Best rainy-season mode · 30% less power3-min airing before turning on is a must
Vent the room's hot air first and the AC cools faster. Open a window for 3 minutes before turning on to shorten the cooling start time.
20% off initial-run powerTurn off 30 min before going out
If the room is already cold, coolness lasts 30 minutes after turning off. Just the habit of turning off 30 minutes before going out saves electricity.

An indoor-outdoor temperature gap within 5~8°C is best for health. If it's 35°C outside, 27~30°C indoors is ideal. Setting it recklessly low brings AC-sickness and wasted electricity at once.

④ Preventing AC-sickness — miss this and you'll ail like a cold all summer
AC-sickness is real enough that hospitals use the diagnosis "cooling sickness." Headache, muscle pain, fatigue, and indigestion are the main symptoms, and severe cases lead to respiratory illness.
๐ 7 ways to prevent AC-sickness
- 1️⃣Keep the indoor-outdoor gap within 5~8°C — sudden temperature changes are the direct cause of AC-sickness.
- 2️⃣Air out 5 minutes every 2 hours — running the AC continuously dries the air and raises CO₂ levels.
- 3️⃣Don't let AC air hit you directly — direct air on joints like the neck, shoulders, and knees causes pain.
- 4️⃣A long-sleeve cardigan is a must — wearing long sleeves in a strongly cooled room is the most effective way to regulate body temperature.
- 5️⃣Drink enough water — AC environments have low humidity so moisture leaves the body fast. 2+ liters a day recommended.
- 6️⃣26~28°C + timer at bedtime — an overly cold environment while sleeping lowers immunity.
- 7️⃣Keep the filter-cleaning cycle — air from a dusty, moldy filter triggers allergies and respiratory illness.

⑤ Outdoor-unit check — miss this and it won't cool
If the AC runs hard but doesn't cool, check the outdoor unit. If the outdoor unit isn't working right, no amount of interior cleaning helps.
๐ฟ Outdoor-unit self-check checklist
✅Keep 30cm+ of space around the unit — pots, luggage, or covers block heat release and drop cooling efficiency below 50%.
✅Remove the outdoor-unit cover for sure — people often leave the winter cover on. Definitely take it off before running.
✅Check the fan spins — if the outdoor fan doesn't spin 30 seconds after turning on the AC, shut it off and call a pro immediately.
✅Check for odd noise/vibration — "rattle" or "screech" sounds signal a fan-motor or compressor problem. Left alone it becomes a big repair bill.
✅Whether the unit is shaded — a unit in strong direct sun gains 10~15% cooling efficiency with a single sunshade.
✅Condition of the connecting-pipe insulation — if the insulation on the pipe linking indoor and outdoor units peels, cooling is lost.

⑥ Call a pro for these symptoms
๐ง 7 symptoms that need a pro check
- Weak cooling even after cleaning the filter — a sign of low refrigerant (gas). Not a DIY fix; needs a pro recharge.Fair cost: gas recharge ₩50k~120k
- Water drips from the indoor unit — a clogged drain pipe. Left alone it leads to wall and ceiling leaks.Fair cost: drain cleaning ₩50k~80k
- A musty smell when running — mold on the internal coil. A cause of allergies and respiratory illness.Fair cost: coil cleaning ₩80k~150k
- Odd noise (rattle·screech·hum) — a fan-motor or compressor problem. Left alone, full failure.₩30k~300k by symptom
- The bill suddenly jumped a lot — compressor efficiency drop or low refrigerant. Needs a check to find the cause.Check fee: ₩20k~30k
- Indoors is hotter than the set temperature — a temperature-sensor malfunction or low refrigerant. Cleaning won't fix it.Sensor replacement: ₩50k~100k
- The outdoor fan won't spin — stop running it immediately. The fan motor needs replacing.Fan motor replacement: ₩150k~300k
