AC Not Dripping Water? Try These Fixes

AC Not Dripping Water

If the air conditioner is cooling your home effectively, it is in good working order but may also be dripping water.

Like any machine, they are likely to become less effective over time and use. Many times, homeowners neglect to repair their air conditioners. Performance might be significantly impacted by neglecting periodic maintenance.

Should AC drip Water Outside?

Yes, this indicates that the system’s refrigeration component is working and that the unit is carrying out its task.

It’s typical to occasionally notice a little pool of water under the exterior unit of your air conditioner. Water in the outdoor unit often indicates that the refrigeration side of the system is working properly and the unit is doing its job.

Water is obviously a good sign if the interior unit is heating properly, yet this does not mean the unit is operating flawlessly as several things might alter performance.

Why Is My AC Not Dripping Water?

Most of the time, dripping or leaking water is not a good indicator for most appliances. However, the air conditioner does the exact opposite!

Since it removes humidity from the air, all that moisture must be disposed of somewhere. Here are a few reasons why your air conditioner might not leak.

A window air conditioner’s condensation collection drips into the bottom of the device. The air conditioner then lets this Water trickle out.

Temperature, humidity, and airflow are a few variables that affect how much liquid flows from an air conditioner.

It will drip more frequently on a hot, muggy day than on a cool, dry day. Near the back of the device, there are drain holes for the air conditioner.

The water should drip out the back of your property if the appliance is installed correctly. Your home’s walls, floors, and furniture could sustain harm from dripping water.

There is a wide range of different air conditioner issues. It’s crucial to comprehend certain problems and how to solve them. Some of the causes are as follows:

1. Condensate Drain Is Blocked

The hole in the back of the air conditioner where water can drain is called the condensate drain. If it’s obstructed, the water won’t be able to drain. Air conditioners work by soaking up the heat and moisture from your house.

Once inside, the humidity-related moisture condenses on metal coils and is transferred to a container known as a drip pan before leaving your home through a PVC pipe known as a drain or condensate line.

A drain line is a perfect place for mold, mildew, and sludge to establish a home because it is an enclosed, moist region. In addition, dirt, debris, and even bugs can get inside. All of these objects have the potential to block the line if they are not routinely emptied.

If you don’t remove the obstruction immediately, water will accumulate in your condenser pan. Even worse, Water can begin to accumulate in your unit’s indoor evaporator pan, which may harm your system or house.

The following are the most typical indications that you might have a drain line:

Your home’s air conditioner isn’t cooling it down, you are unable to switch on the AC Higher energy costs, visible water leaks from the unit, increasing interior humidity, and unfamiliar smells/odors caused by the buildup of Mold/Algae.

Fix One: Fix The Blockage

Most homeowners may need to do the relatively straightforward chore of unblocking an AC drain line at some point. Follow these steps to clear your AC condensate drain line:

1. Check the clog

Check the drain line’s exit point outdoors to see if there is a little obstruction. Occasionally, clearing the clog is a quick treatment that may be done outside. Additionally, check the drain pan to see whether the obstacle is in the line connecting to it.

2. Remove the clog by hand

If the obstruction is only slight, you might be able to clear it out by hand. First, locate the discharge of the drain pipe. The discharge is typically found on the side of your house, outside. Try to clear the clog by sticking a finger up the drain line from each end. Sometimes the obstruction is small enough that you may quickly remove it manually and restart your air conditioner.

Other times, clearing the obstruction in the condensate line requires a little more work. First, you must locate and clean out the clogged AC unit in your home. Continue reading if your condensate drain pipe is still plugged.

3. Turn off power to your AC unit

You must first switch off the power because you’ll be disassembling the drain pipe. Locate the AC unit’s disconnect switch and flip it off. While working on the condensate drain line, your AC must be turned off.

4. Locate the condensate drain line

The next step is locating where the condensate drain pipe enters your air conditioner. The air handling unit, which is typically in your garage or attic, will have a condensate drain line connected to it.

5. Clean and unclog the vent tee

The air handler is close to the vent tee. Usually, a piece of plastic covers the top of the tee. The condensate pipe can be cleaned using the vent tee as an access point. Examine the inside of the tee after removing the plastic top.

There may be some slime accumulation inside. If so, you’ve discovered where your clog originated. Use a vacuum to blow air through the vent tee to clean it out. To create a seal with the vacuum hose, you might need to wrap a rag around the vent tee.

Use a drain gun in its place if your vacuum is unable to clear the obstruction from the condensate line. High-pressure gas will be injected into the drain pipe using a drain gun. Almost any block may be removed thanks to the strong pressure.

6. Sanitize the drain line

After clearing the buildup from the tee with a blowtorch, flush the condensate line with water. Look at the discharge end of the line attached to your house’s side.

The amount of debris you blew out of your line may surprise you. Additionally, you want to flush vinegar down your drain line to aid in dissolving and getting rid of buildup.

2. The Air is Dry

In addition to being necessary for both homes and workplaces, an air conditioner can also make a room dry by dramatically reducing humidity. Dehumidifying capabilities are included in air conditioning systems. It consequently tends to dry out the air.

Dryness in the space could give rise to several issues that might be more significant than you realize.

First, less humid surroundings can lead to dry skin because they reduce moisture in the stratum corneum, the skin’s outer layer, and they can stop Water from the air conditioner from dripping.

Fix: Remove AC Unit

Since there is no air to condense, the AC is not necessary.

3. The Condition is tilted forward

The installation was flawed if you recently installed a new window air conditioner and it began to leak immediately. Leakage could be caused by several factors, which may be the most obvious indication that an installation was done incorrectly.

Water may collect in the front of an air conditioner unit that is flat or slanted forward rather than draining out the back outlet. Most air conditioners need to be tilted half an inch while being installed.

Fix: Correct AC Position

There must be a level area available for the central air conditioner. Use an AC pad to fix the issue on an uneven surface.

The front should be angled upward from the front to prevent water from flowing inside when using window air conditioning

Continuously guarantee that an experienced specialist is installing a new device.

A window air conditioner should often be angled. Some more recent versions, nevertheless, no longer demand a tilt. Read the instructions to choose the optimal installation strategy for your window unit.

4. Rusty Drain Pan

To catch condensation as it drips, a drain pan is positioned beneath or inside the air handler of your air conditioner.

The Water then flows outside and into the drain pipe from this point. If the drain pan is damaged or rusty, the Water will start to leak instead of flowing into the drain line.

When your air conditioning machine is roughly 15-20+ years old, it will start displaying indications of aging, and a rusty drain is one regular occurrence. Over time, the drain pan may rust and corrode, causing your AC to leak Water.

Rusting occurs when the iron is involved due to water and air (oxygen) combined effects. The drain pan deteriorates fast because it is composed of metal.

The unit may become blocked due to persistent corrosion in the drain pan, obstructing the flow of water outside. In the end, this causes spills and causes air conditioning to leak.

Fix: Replace Drain Pipe

You can either replace a corroded drain pan or refinish it by following these instructions:

Mold and rust buildups can be removed from the drain pan by washing it with Water, dish soap, and a brush.

1. Dry the pan completely. You can do this using a drier or a hot air gun.

2. Take off as much rust as you can with sandpaper.

3. To completely get rid of the powdered rust, clean the drain pan once more.

4. Apply a rust converter for the final step. Finally, coat all the damaged areas and allow them to dry.

It is necessary to properly and securely seal a cracked drain pan. Clean the drain pan thoroughly first, then locate any cracks with a flashlight and some water.

5. Patch the cracks using a high-quality water-resistant sealer, then test the repair by letting the waterfall again.

6. Replace a corroded drain pan as soon as possible. Any drain pan won’t do; for your AC to function properly, it must be the correct size.

5. Faulty Condensate Pump

The water produced in a heating or boiling system is pumped using condensate pumps. However, if your condensate pump isn’t operating as it should, it may require cleaning, repair, or even replacement.

Therefore, running your air conditioning system is risky if the condensate pump isn’t functioning properly because it might result in water damage and other pricey long-term repairs.

Only homes with window air conditioners with condensate pumps below ground are eligible for this.

It can be challenging for water to exit your drain line if your central HVAC unit is situated in a location like a basement or a remote attic. Here, the condensate pump is crucial to clearing the system of water.

When the reservoir’s water level rises, the float switch on the condensate pump turns on. The condensate pump then started to drain water outside of your house.

It won’t pump water outside the unit if the float switch or condensate pump are damaged. As a result, your air conditioner will begin to leak water as it builds up.

Fix: Replace Condensate Pump

The pump should be powered off.

1. Power off the air conditioner and the condensate pump if you think your condensate pump could be broken. Ensure the pump’s high- and low-voltage wires are both unplugged.

A float is a component found at the top of every condensate pump. Sometimes, this tiny component can get caught and cause the pump to turn off.

2. Tap the float until it is free to move if it becomes stuck. You must replace the float if you find it cracked or otherwise damaged.

3. Complete steps one and two, then thoroughly clean the pump. Water from the pump and tank should be dumped after removing the pump’s outer housing. Next, the entire device, including the float, should be cleaned with warm, soapy water and a fresh washcloth.

4. After cleaning, if the pump is still not functioning, cut the lines attached to the pump using a pair of wire cutters. To ensure you have some wire you work with when replacing the pump, leave a portion of the wire.

5. New pump after removing the old one. After gently removing the old pump from its spot, swap it with the new one.

6. Place the new plumbing lines in place and reconnect the electrical wiring. Turn the new pump on after installation, then fill it with water to test it. Once the Water has been poured, if the pump stops operating, keep adding Water until it functions properly.

6. Your Window AC Has A Slinger Ring

A “slinger ring” surrounds the rear fan blade on all room air conditioners. The ring aims to scoop water from the pan’s bottom and hurl it at the condenser coils.

By decreasing heat on the coils and assisting in removing moisture from the pan, this design element increases the appliance’s efficiency.

A pinging or sloshing sound is typical as the fan blade passes through the Water.

Some of the recent window air conditioners are equipped with a slinger ring. The drain pan is dipped into the slinger ring, which then launches the gathered Water back onto the coils. This stops leakage and aids in coil cooling.

Fix: No Reasonable Fix

This problem cannot be solved by you alone. To get it fixed or replaced, depending on the damage, get in touch with a specialist.

7. Debris-Filled Air Filters

Evaporator coils can freeze due to clogged air filters, resulting in water leaks from your air conditioner. The filters guarantee appropriate airflow. Clean air can enter your home thanks to its capture of air contaminants.

However, this debris and dust can build up inside the filters and completely block them with time.

Your unit may also be harmed by their obstruction, which is hazardous to indoor air quality. Furthermore, the heated air is more challenging to pass through clogged air filters. The evaporator coils eventually freeze due to the refrigerant failing to absorb the heat.

Fix: Remove Debris

Make careful you properly collect the dripping Water first. Do not allow it to damage your walls or floor. Start cleaning your filters after that. Before reinstalling the filters in your device, it will enable them to dry thoroughly.

When your air conditioning system is utilized for extended periods during the peak season, it is advisable to clean the air filter more frequently. For example, every two weeks, clean them and replace them every three to four months.

If you have a mini-split, Window, or portable air conditioner, you can set reminders, but a smart AC controller is a better choice.

For instance, the Cielo Breez smart controller may assist you in keeping track of the level of air filter cleanliness and alert you when the next cleaning is necessary.


Air conditioning systems in every house or office improve indoor air quality and provide a comfortable environment.

Air conditioners are more of great value than pleasure because working in extreme heat may be incredibly painful. It helps business owners create a pleasant workplace while enabling homeowners to create a comfortable environment for the entire family.

The Water in the air conditioner needs to be let out to prevent stagnation. Summertime usually sees a rise in the volume of stagnant water.

To preserve hygiene, kindly frequently drain the water from the air conditioner. If water is not evacuated from the cooling device, bacteria can grow there, and this step is crucial to prevent that from happening.
