There are many amazing features of an air conditioning unit, but the ability to drip water as it operates is completely not on the list. So, if it is happening in your A/C today, better call the professionals for help. You may not know what’s causing it, but it is obvious that something is wrong inside.
Here are the most common reasons why your home’s A/C leaks water and what you should do about it.
Clogged Condensate Drain Line
This is probably the first thing that you should check when your air conditioning unit drips water. The accumulation of dirt, dust, and mold blocks the proper flow of water in the drain line causing it to move back to your home. Unclogging the line is your only choice, and you can call your trusted HVAC professional for help. There are special vacuums used to remove the materials from the drain line and bring back the proper flow of water.
Damaged or Rusted Drain Pan
Another thing that might be causing the water to leak out is a damaged drain pan. This happens most of the time with old air conditioning units. When the drain pan is already damaged or rusted, it can no longer hold the water and will just fall through it. Immediately replace the pan to stop the water from leaking out.
Frozen Evaporator Coils
Do you see ice buildup around the evaporator coils? When the ice melts, the water drips from your air conditioning unit. But that’s not the only danger for when your unit runs too long with a frozen evaporator coil. You might end up with a broken compressor. This is a serious issue which needs a very expensive fix. If you have a case of frozen coils, better call an HVAC technician right away.
When the air filter is filled with dirt and dust, the proper airflow is compromised. Insufficient air flow allows the coils to freeze and form ice. And when the ice melts, a great amount of water drips in the pan which it may not be able to handle. Be sure to replace or clean your air filters regularly to prevent the occurrence of this issue.
Just like a dirty air filter, low refrigerant will reduce the pressure inside the system and cause the evaporator coil to freeze over. Take note of the signs that you have a low refrigerant level like the A/C isn’t cooling your home well enough or you hear a bubbling noise which indicates the presence of refrigerant leaks.
