What To Know
- If the pump is faulty, it may not be able to pump the water out of the unit, which can cause it to leak.
- Water leaking from the inside of the air conditioner is usually caused by a clogged condensate drain line or a dirty evaporator coil.
- Water leaking from the outside of the air conditioner is usually caused by a broken condensate pan or a faulty drain pump.
If your air conditioner is pouring water, it can be a frustrating and potentially costly problem. However, understanding the causes and knowing how to troubleshoot the issue can help you resolve it quickly and effectively.
Causes of Water Leakage from Air Conditioners
There are several reasons why your air conditioner might be leaking water:
1. Clogged Condensate Drain Line
The most common cause of water leakage is a clogged condensate drain line. This line drains condensation from the evaporator coil outside the unit. If the line becomes blocked, water can back up and leak from the unit.
2. Dirty Evaporator Coil
Over time, the evaporator coil can become dirty with dust, pollen, and other debris. This can reduce the coil’s efficiency and cause water to freeze on the coil. As the ice melts, it can overflow and leak water.
3. Refrigerant Leaks
If your air conditioner has a refrigerant leak, it can cause the evaporator coil to freeze and leak water. Refrigerant leaks can also damage the compressor and other components of the unit.
4. Broken Condensate Pan
The condensate pan is located under the evaporator coil and collects the condensation. If the pan is cracked or damaged, water can leak from it.
5. Faulty Drain Pump
Some air conditioners have a drain pump to help remove condensation. If the pump is faulty, it may not be able to pump the water out of the unit, which can cause it to leak.
Troubleshooting and Repairing a Leaking Air Conditioner
1. Inspect the Condensate Drain Line
Check the condensate drain line for any blockages. Use a wet/dry vacuum to clear any debris or obstructions.
2. Clean the Evaporator Coil
Turn off the power to the air conditioner and remove the access panel to the evaporator coil. Use a soft brush or vacuum to clean the coil.
3. Check for Refrigerant Leaks
If you suspect a refrigerant leak, call a qualified HVAC technician. Refrigerant leaks can be dangerous and require professional repair.
4. Replace the Condensate Pan
If the condensate pan is cracked or damaged, it will need to be replaced. Turn off the power to the air conditioner and remove the pan. Replace it with a new pan of the same size and shape.
5. Repair or Replace the Drain Pump
If the drain pump is faulty, it will need to be repaired or replaced. Turn off the power to the air conditioner and remove the drain pump. Inspect the pump for any damage or clogs. If the pump is damaged, it will need to be replaced.
Preventing Air Conditioner Water Leaks
To prevent water leaks from your air conditioner, follow these tips:
- Regularly inspect and clean the condensate drain line.
- Change the air filter every 1-3 months.
- Keep the area around the outdoor unit clear of debris.
- Schedule regular maintenance with a qualified HVAC technician.
