LG AC Blockage Repair in Chennai
Blocked filters, drains or airflow paths cut cooling and can cause leaks.
When an LG Dual Inverter or split air conditioner experiences internal obstructions, cooling efficiency drops rapidly and water may begin spilling from the indoor unit. In Chennai’s humid climate, accumulated airborne dust, mold growth, and lint combine with condensation to choke critical airflow pathways and condensate drain channels. Resolving these blockages requires specialized flushing and deep cleaning to protect the AC’s inverter compressor from overheating.
Common Symptoms of Blockage in LG ACs- Water dripping or overflowing directly from the bottom of the LG indoor split unit.
- Ice formation along the evaporator coils or copper refrigerant lines.
- Significantly reduced airflow or weak throw coming from the louver vents.
- Musty, damp odors blowing into the room whenever the fan turns on.
- LG display panels showing error codes related to indoor fan speed or airflow restrictions (such as CH41 or CH44).
- Slime and Mold in Drain Pan: High humidity in Chennai creates thick bio-slime in the LG condensation tray, plugging the drain outlet.
- Clogged EZ Clean HD Filters: Fine dust clogging the high-density micro-antibacterial filters, strangling intake air.
- Dirty Evaporator Coils: Micro-dust adhering to the aluminum fins, restricting heat exchange and freezing moisture.
- Blocked Drain Hose Pipe: Foreign particles, insect nests, or severe bend trapped inside the external plastic drain line.
- Diagnostic Check: We inspect the LG indoor unit air intake, filter condition, blower wheel, and external drain hose outlet.
- Jet Pump Chemical Wash: We apply safe cleaning solutions and high-pressure water jets to flush out trapped sludge, algae, and grime from the evaporator coils and drain pan.
- Drain Line Clearance: Pressurized air or mechanical flushing is used to clear the entire length of the condensate pipe, ensuring free gravity flow.
- Blower Fan Cleaning: We strip dirt build-up from the cross-flow fan wheel to restore factory-rated air throw.
- Performance Audit: Reassembling the unit, verifying condensate drainage, measuring air supply temperature, and checking overall cooling efficiency.

Frequently asked questions
Why is my LG split AC leaking water inside the room?
Water spills indoors when the condensate drain pan or drain pipe becomes blocked with dirt and algae, forcing condensed moisture to overflow the internal tray instead of draining outside.
Can I clear a blocked LG AC drain pipe by myself?
While cleaning the outer mesh filters is easy, clearing deep blockages inside the internal drain pan and coil requires dismantling the front casing and using high-pressure jet pumps, which is best handled by a technician.
How long does it take to fix an AC blockage on an LG unit?
A thorough jet service and drain flushing for an LG split AC typically takes around 45 to 60 minutes to complete properly.
Does Janani Cool Care provide a warranty on AC blockage repair?
Yes, we provide a 30-day service warranty on our cleaning and blockage clearance work to ensure your AC runs smoothly and leak-free.
