Your AC drainpipe can become clogged with mold and mildew that forms in standing water within the AC condensate drain pan. A clog may also be due to general dust, dirt, dander, or debris entering the drain line. It could even be caused by a spider building a web!
There could be several reasons why your AC unit is not releasing water. One reason can be that there is a clog in the drain line, which prevents the moisture from draining properly. Another possibility is that there's an issue with the condensate pump responsible for pumping out excess moisture.
1 Answer 1 That is a classic case of the drain line being clogged. Usually it's clogged with gunky stuff that has grown in the condensate (water) in the drain line. Find the termination of the drain. It is outside the house or drains to another drain in the basement or garage. Use a shop vac to suck out what you can.
When the AC is on but no water is coming out, it's not necessarily dangerous. This could simply mean that the humidity level is low, or the condensate drain line is clear, allowing water to evaporate before it exits the unit.
Locate the white plastic pipe that leads outside, then check for any blockages like debris or ice. Defrost ice with warm water, not boiling, and use a rod or wire to push through the obstruction. If that doesn't work, call a pro with specialist equipment.
To unclog an AC drain line, turn off the power to the unit. Locate the drain line and use a wet/dry vacuum to suck out the clog. Flush the line with water using a garden hose or cup of water. Check and clean the drain pan under the indoor unit.
It doesn't let the water drain out of the system. This can produce a pungent smell and even cause health issues like vomiting, headaches, and breathing problems.
The condition of your air conditioner is good if it is cooling properly, but it may require dripping water too. The absence of dripping water may be caused by dry air. You shouldn't be alarmed if this happens to your AC because it won't affect its performance.
Cleaning AC Drain Line
We recommend using vinegar instead of a bleach solution because bleach can cause corrosion if you have copper tubing in your AC's drain line. In addition, spilling bleach can ruin your carpet or clothing, whereas vinegar does not harm; it just leaves an odor.
A clogged condensate drain line will trap water in your air conditioner. As a result, the evaporator coil will eventually turn to ice. The moisture in the drain line can also freeze, which will cause your air conditioner to turn off. But before it does, it'll likely suffer some damage.
What causes an air conditioner drain line to clog? Your AC drainpipe can become clogged with mold and mildew that forms in standing water within the AC condensate drain pan.

Flush Condensate Drain Line
The repair cost to have the drain line flushed runs between $75 to $250.
Clogged Tubing and Emitters
Drip irrigation uses a system of hoses, tubes and emitter devices, sometimes called drippers, with small openings that allow water to drip out slowly. Emitters have very small openings ranging from 0.2 to 2.0 mm in diameter and can become blocked with sediments naturally found in water.
A puddle of water on the ground near your air conditioner is one of the first and most obvious signs that your drain line is stopped up. A clogged AC drain line is no joke because it can cause extensive water damage to your home, including mold and weakening your structural foundation.
It's completely normal for your AC to drain 5-20 gallons of water outside of your home (via the condensate drain). It's NOT normal for your AC to drain any amount of water inside your home (around your indoor AC unit).
Ensure that the solution reaches as far as possible down the line. Let it sit for about 30 minutes to allow the vinegar to break down any buildup. Flush the Drain Line.
Many HVAC professionals suggest that you avoid using harsh chemicals such as Drano to unclog the block.
First, check your filters and coils for dirt and debris that may be impeding airflow. Once you've cleaned the filters and coils, run the air conditioner with just the fan so that the ice accumulation can melt off. If the AC still doesn't blow cold air, it could be that refrigerant levels are too low.
One of the most common reasons for a clogged drain pan is the presence of a defective drip pan. Drip pans are meant to drain water away from your A/C condenser with an easy-to-use hose. If your AC drain pan has rusted or corroded, there's a good chance that it no longer works.
It's possible in some weather conditions that the air is dry enough not to condense any water on the coil, and it's not necessarily just when humidity is low. It's all about dew point. If the dew point is below 55°F, it's likely you'll have little to no condensate.
If the air conditioner is not properly draining water, it indicates that there is a leak occurring somewhere else in the system. To address this issue, it is crucial to rely on the expertise of a skilled technician who can first identify the problem among the potential causes.
While a little condensation is normal, larger amounts of water continuously dripping from your air conditioner can be a cause for concern. And the reason for this can be anything from the air conditioner's filter to its air vents. Or you may need to replace it.
