No Water Coming Out of AC Drain Pipe – What’s Wrong?

You may have noticed that no water is coming out of the AC drain, but you’re not sure why. I asked experts to respond to your questions! If the condensate from the air conditioner is not properly drained, it can collect elsewhere and cause mold. Suppose you notice that the air conditioner is not draining correctly. In that case, you must take specific steps to restore the unit’s functionality. Continue reading to learn about the cause of this problem and how to solve it.

Why Does an AC Produce Condensate Water?

Before going deeper into the causes of a dry AC drain pipe, you should first understand why your air conditioner produces condensate water in the first place. When your air conditioner cools the indoor air, it removes moisture, resulting in humidity. This humidity condenses into water, which collects beneath the evaporator coil in a drip pan. The water then flows through a drain pipe outside your home or into a drainage system.

Why is There No Water Coming Out of The AC Drain Pipe?

The drain may be clogged if no water drains from the AC drain. Water usually collects in the air conditioner’s condensed water pan when the drain pipe becomes clogged. If the blockage is not removed, the drain pan may overflow, causing significant flood damage.

A faulty evaporator coil could also be the source of this issue. A faulty evaporator coil can also cause the leaking of water from the central air conditioner.

Don’t sure whether it is the evaporator coil issue? Also, read how to clean the evaporative coil thoroughly to ensure its proper working.

Why Does My AC Drain Pipe Keep Clogging?

Algae is one of the most common causes of AC pipe clogging. Warm air is blown onto the cooling evaporator coil, causing dampness in the drain pipe.

It, together with the condensate that flows through the pipe, creates an ideal environment for algae to grow. The drainage pipes are more likely clogged if you run the air conditioner frequently.

How Do I Know My AC Drain Pipe Is Clogged?

The pipe may be clogged if the air conditioner does not work correctly. The AC drain line’s function is to remove excess condensation from the unit. You may notice a small drop of water on the end of the PVC pipe when you turn on the device. It is where moisture enters the system and is also the source of problems such as water buildup and clogging. Other symptoms of a clogged AC drain pipe are listed below.

Extra water:

Water may be found in excess throughout the air handling unit. The water safety switch may be activated if the air conditioner is not working correctly or due to a clogged AC pipe.

It will stop the device from working correctly. Look for standing water near the security switch. It could have caused the air conditioner to malfunction.

Moldy Odor:

A musty odor in your home could indicate a buildup in the system. Your air conditioner may still be operational, but it stinks. If you smell this odour, the drain is probably clogged.

Bread with Full Condensate:

Clogging can occur when using bread with full condensate. To prevent mold growth, you must address the problem as soon as possible.

What should I do if the air conditioner won’t turn off?

If your air conditioner is not draining correctly, you should address the problem immediately. Here are some steps that may assist you in resolving the issue:

First, Turn Off The Air Conditioner:

When performing maintenance, make sure to turn off the air conditioner. Some moving parts can cause injury or damage to the device if left in place.

Step 2: Examine The Drain Pan:

The air conditioner’s drain pan is located beneath the evaporator. Always keep an eye out for water pools. The presence of water indicates that the line has become clogged. If there is no water in the drain pan and no drain, the drain pipe is broken.

Step 3: Remove Water:

If the air conditioner’s drain pan overflows, drain and dry it immediately. A wet/dry vacuum cleaner can be used for this. Remove any other debris from the drain pan.

Mold or mold stains can harm your health if water seeps into the insulation or damages mold or gypsum board. You should contact a professional company.

Step 4: Clean The Drain Pipe: 

After the water damage has been repaired, the condensed water line must be cleaned. Fortunately, you can complete this task on your own.

  • Double-check that the drain pipe is connected to the drain pan.
  • Look for a drain outside the house. Place a bucket beneath it once you’ve found it. • Remove slime and dirt from the line’s ends with a wire brush.
  • Determine the location of the drain pan access point.
  • Combine the bleach and water and pour it down the drain. Then set it aside for about 30 minutes.
  • Examine the bucket to see if the AC condensed water drain line drains appropriately.
  • After cleaning the clogged drain, water should immediately flow through the pipe and drain. If this does not properly drain the air conditioner, contact an HVAC repair company to resolve the problem.

Other Possible Reasons For No Water From AC Drain Pipe:

Incorrect Installation:

An improperly installed air conditioning system can also cause drain pipe problems. Water may not flow properly if the drain line is not properly sloped. Standing water or even reverse flow can result from this. To avoid this issue, proper installation by a qualified technician is essential.

Low Relative Humidity:

If the air in your space is exceptionally dry, the air conditioner may not produce much condensate water. This is more likely in arid regions or when the weather is cooler. If your air conditioner appears to be functioning normally, low humidity levels could be the simple explanation for the dry drain pipe.

Ventilation Obstruction:

Another lesser-known problem that can impair the performance of your air conditioner is blocked ventilation. Airflow can be hampered if furniture, curtains, or other items obstruct the return and supply vents in your home. The system may not produce much condensation if it does not receive enough warm, moist air to cool.

Inadequate Refrigerant:

Inadequate refrigerant levels in your AC system can reduce cooling efficiency. When the system fails to cool the air adequately, less condensed water is produced.

How Much Water Should Drain From An Air Conditioner?

The answer to this question depends on the season and time of year the air conditioner is used. Air conditioners can discharge 5 to 20 gallons of water daily in humid summers, which is normal.

It is usual for your device to drain this water from your home. However, when the water in your home is drained, this becomes a problem. If there is water in the house, the air conditioner will need to be repaired or replaced.

What Happens When AC Doesn’t Drain?

If the Drain Line becomes clogged, the water in the air conditioner will accumulate and have nowhere to go. It eventually evaporates and returns to the atmosphere. It will raise the humidity level in the room. Unpleasant air can enter the house if the humidity is too high.

How Often Should I Clean My AC Drain Pipe?

AC drains connect AC devices to the outside of a building or house. As a result, it is critical to keep it clean for it to function correctly. The entire system will fail to work if the AC drain pipe becomes clogged. It should be cleaned every 30 days to avoid this.

What To Do If The Water Is Not Coming Out Of AC Drain Pipe!

A water block on the drain line of the drain tube prevents unfiltered external air from being sucked into the internal coil. The line is clogged if no water drains from the AC drain pipe. It is a simple problem to solve
