9 Air Conditioner Maintenance and Care Tips
-
In East Africa, air conditioners aren’t just for the hot season; they’ve become essential all year round. Whether you're dealing with the blazing January sun or the current cold July breeze, your residential air conditioners play a big role in keeping your home comfortable, clean, and energy efficient.
That’s why proper air conditioner (AC) maintenance matters. A well-maintained air conditioner cools better, lasts longer, and even helps purify the air you breathe during the chilly, dusty seasons.
Here are simple and effective air conditioner maintenance tips to help you get the best out of your LG Residential AC, no matter the season.

1. Clean or Replace Your Air Filters Regularly
Your AC filter is the first line of defense against dust, pollen, and indoor air pollution. Whether it’s hot or cold outside, a dirty filter will block airflow, reduce cooling or heating efficiency, and compromise air quality.
Why it's important:
• Cleaner air for your family
• Lower electricity bills
• Better cooling and air purification
How to clean your LG AC filter:
1. Turn off the AC and unplug it.
2. Open the front panel and remove the filter.
3. Rinse it gently with lukewarm water and mild soap.
4. Let it air dry completely before reinstalling.
Recommended: Clean your air conditioner filter every 2 to 4 weeks, or more frequently if you live in a dusty area or near heavy traffic.

2. Clean the Evaporator and Condenser Coils
These coils help your AC absorb and release heat. Over time, dirt collects on them, especially during windy or dusty months, reducing your air conditioner's performance.
How to clean:
• Switch off the power at the main source.
• Use a soft brush or vacuum cleaner to remove dust gently.
• Never use sharp objects or water directly.
Pro tip: Do this at least twice a year before the hot season and just after.

3. Clear the Drain Channels
Your air conditioner not only cools the air but also removes excess moisture. If the drain is blocked, it can lead to indoor leaks, higher humidity, or mold growth, especially in cooler months when the AC is on low or off.
Signs of clogged drains:
• Water dripping indoors
• Musty smell from vents
• Dampness around the un
Quick fix: Use a stiff wire or pipe cleaner to gently unblock the drain line. If unsure, call a professional.

4. Check and Calibrate the Thermostat
Your AC's thermostat needs to sense room temperature accurately. If it’s off, your AC unit could be overworking or not cooling efficiently.
For LG Smart ACs:
• Use the LG ThinQ app to control, monitor, and schedule your AC remotely.
• Adjust temperature settings from your phone, perfect for managing energy use when you’re away or at night during cold weather.

5. Seal Leaky Ducts and Insulate Properly
Especially in older homes, cool or warm air can escape through cracks in ducts or poorly insulated walls, making your AC work overtime.
Signs of leakage:
• Some rooms are harder to cool or heat
• Weak airflow from certain vents
• Unexpected rise in electricity bills
Consider calling a technician to inspect and seal leaks. Proper insulation will also help your AC maintain the right temperature with less effort.

6. Cover the Outdoor Unit During Long Off-Seasons
If you’re not using your AC during the cold months, protect the outdoor unit from rain, dust, and debris.
How to cover it safely:
• Use a breathable, water-resistant cover.
• Avoid plastic or airtight materials, as they trap moisture and can cause rust.
Uncover the unit fully and inspect it before use when the heat returns.
-
7. Schedule a Professional Service at Least Once a Year
Some issues are better handled by experts, especially internal parts, gas levels, and diagnostics.
Why annual Air Conditioner Service is worth it:
• Deep cleaning of coils and fans
• System performance check
• Early detection of faults
• Prolongs the life of your AC
