Why Is Water Coming From My Air Conditioner?

Your air conditioner gathers moisture from the room and expels it outdoors as part of its normal operation. If your AC is dripping moisture indoors, it usually indicates a problem. In today’s post, your local HVAC contractors at Amber Air Conditioning Inc. discuss the reasons behind why your AC is dripping water.

Where Is the Moisture Coming From?

The air handler in air conditioners collects moisture along with heat and particulates, which are filtered and pumped outdoors through a drain line. The moisture is then collected in a drip pan, which sends the moisture towards the drains or may need to be emptied periodically. If operating normally, you won’t have to worry about the moisture making its way back into your home.

Why Is My AC Dripping Water?

If you notice moisture coming from your AC, turn it off and call your HVAC technician. The issue may be caused by one or more of the following:

• Clogged air filter. A clogged air filter may block airflow and cause the evaporator coils to ice over, which can result in water dripping as they thaw. Ideally, air filters should be replaced every three months — or cleaned, if it’s in a ductless mini-split AC.
• Broken condenser pump. A condenser pump is responsible for pushing the moisture collected from inside. If this pump is broken, the moisture will build up in the lines and start to leak.
• Installation error. If moisture is coming from a recently-installed air conditioning system, chances are the problem is caused by an installation error. Condensate lines, in particular, need to be properly connected and angled relative to the outdoor unit. Improper installation can result in backflow and/or leaks.
• Clogged drain line. Drain lines can get clogged over time and cause backflow. Dust and small particles may make their way inside. Moss and algae may grow inside, unseen.
• Refrigerant leak. Refrigerant is the substance that is cycled in the air conditioner to generate cool air. If the refrigerant leaks, one of things that will happen is the evaporator coils will start frosting over. When the air conditioner is turned off, the frost melts and leaks back indoors.
