This article will combine hot topics and user feedback in the past 10 days to provide you with detailed solutions, and attach structured data for quick reference.
1. Analysis of common causes of air conditioner leakage

According to statistics from discussions and maintenance data across the Internet, the main reasons for air conditioner leakage are as follows:
| Reason | Proportion | Typical symptoms |
|---|---|---|
| clogged drain pipe | 45% | Internal machine dripping and poor drainage |
| Installation tilt | 25% | Water drops dripping along the panel |
| Filter is dirty | 15% | Condensate overflows into the drain pan |
| Insufficient refrigerant | 10% | The internal unit melts water after freezing |
| other reasons | 5% | Cracked drain pan, etc. |
2. Step-by-step solution
Step 1: Check the drain pipe
After turning off the air conditioner, use a thin wire to clear the drain pipe (usually a white plastic pipe), or use a vacuum cleaner to suck out the blockage. If the drain pipe is old and cracked, it needs to be replaced with a new pipe.
Step 2: Adjust leveling
Use a level to measure whether the internal unit is tilted (the standard is that the drain outlet side is 1-2 degrees lower), loosen the fixing screws, adjust them and retighten them. Note: The outdoor unit should be kept absolutely level.
Step 3: Clean the filter
Remove the filter and clean it with neutral detergent at least once a month. If it is seriously dirty, spray the evaporator with special air-conditioning cleaner.
Step 4: Replenish refrigerant
If the cooling effect of the air conditioner drops significantly and frost forms, you need to contact a professional to check the pressure and add R22 or R410A refrigerant according to the model.

3. Preventive measures
1.Regular maintenance: Check the drainage system before use every season and deep clean it once a year
2.Correct use: It is recommended to set the cooling temperature above 26°C to avoid long-term low-temperature operation.
3.environmental management: Maintaining indoor ventilation and lowering humidity can reduce the generation of condensation water
4. Maintenance cost reference
| Services | market price range |
|---|---|
| Unblock drain pipes | 80-150 yuan |
| Replenish refrigerant | 200-400 yuan/pressure |
| Reinstall | 150-300 yuan |
