Why Is Rain Water Coming Through My Window Air Conditioner?
Is your window ac unit dripping rainwater inside your house? You might be wondering what could be the reason, though you have not noticed this problem even a few days. Here are the tops reasons to check to find the main culprit:
Reason 1: Dirty Air Filters
When was the last you cleaned your AC air filters? Since they accumulate a lot of dirt, grime, and pollutants from the external environment, the filter will be dirty or blocked.
This will make the evaporator coils of the ac unit frozen, and then rain will come through the window ac and spill inside the house.
Reason 2: Defective Condensate Tray
The main job of the condensate tray in a window air conditioner is collecting the condensed water.
However, water will enter the room if the tray has become defective or broken due to leakage issues.
Hence, more water will seep inside the house as long as the ac unit operates.
Reason 3: Obstructed Drain Pipe
Each window AC system is connected with a drainpipe, which main role is carrying out the water.
However, it will fail to perform its job if there is any huge blockage inside the pipe. Instead of moving the water outside, it will move backward and drip over the AC unit, flooding the floor surface.
Reason 4: Installing the AC Incorrectly
How much sure are you that you have installed the AC unit correctly? Following any wrong method to set up a window AC unit will lead to water leakage issues.
Generally, when there are any holes or gaps between your condensate tray and the air conditioner, the accumulated water, and the rainwater will begin dripping and enter the room.
Hence, it is necessary to install your AC unit correctly by hiring a reliable professional. Ensure to re-install your AC unit correctly if you have followed the wrong installation approach. In the case of the outside ac unit, buzzing noise happens.
Reason 5: Inadequate Refrigerant Level
It is crucial to have an adequate refrigerant level inside your AC system. Excessively low refrigerants will cause air conditioner pressure to disrupt.
As a result, the evaporator coils will start to freeze, and the water will seep inside the room. Thus, you should always maintain a sufficient refrigerant level for a smooth AC operation.
How to Prevent Rain Water Coming Through Window Air Conditioner?
If you don’t take protective action when rainwater comes through the air conditioner, it can lead to major damage inside your house.
Wood rots may develop because of the rainwater, which will lead to mold development in the surrounding areas of the AC unit.
Generally, you will notice water footprints on the air conditioner wall right below it when rainwater is dripping through it.
Alternatively, puddles might be visible in the close by flooring area. Fixing this problem is necessary to avoid any dangerous accidents in the future.
Here are the steps to follow if you wonder how to prevent rainwater from coming through the window air conditioner.
Step 1: Inspecting the AC Unit
First, give a close inspection of your AC unit to become 100% sure that you have installed it correctly without any problem.
There should not be any holes or gaps between the window frame and the window itself from the upper part and lower part of the AC unit. Also, make sure each side of the window frame doesn’t have any gaps that contact with ac unit.
Step 2: Adjusting the AC Position
If you notice even a slight gap, you should go for a proper adjustment. Don’t forget to place the AC unit in a perfect position on the window. It should be appropriately balanced and aligned.
Make sure you give special attention to the lower part of the air conditioner to secure its position. You need to use a minimum of two screws to tighten its position securely.
Step 3: Final Inspection
Finally, give a further inspect all side panels of the ac unit to confirm they are closely contacted with the window’s edge. Make sure you have tightened the screws properly so that they don’t become loose in the future.
Also, check out all the panels of the AC system if they have any holes because this will accumulate water otherwise. You can use silicone caulk to seal the holes since they are more flexible than latex caulk.

Frequently Asked Questions
Will rain damage a window air conditioner?
Though typical rain won’t cause any harm to the AC unit, deep standing water with more than 15 inches of coverage can pose a serious threat to air conditioners. It may cause damage to electrical parts as well as the moving parts when they are exposed to the water for an extended period.
Is it safe to use a window air conditioner during the rain?
Yes, you can safely run a window air conditioner during the rain since it won’t cause any harm to the AC system. It won’t cause any compromise in performance because each electrical part of an AC unit is properly sealed to prevent water from entering inside.
Can we use split ac during rain?
Split air conditioners have a mounted high design, which is mainly ideal for cooling larger spaces. Like other normal ACs, you can use them during the heavy rain. But make sure rainwater doesn’t touch both the air-cooled condensing unit and the air handling unit.
Can you run window ac during a thunderstorm?
Yes, you can run your window AC even during thunderstorms or Lightning strikes because they are electrically insulated to ensure no damage to the body. Also, it features a nonflammable refrigerant, offering optimal safety and no causes of the explosion.
Most window air conditioners are designed effectively so that thunderstorms and rainwater won’t harm the AC unit. Since all parts of the AC unit are correctly sealed, they won’t cause any threat to the AC unit. However, if you don’t take the proper care, you may experience rainwater coming through the window air conditioner.
You make sure to go for regular maintenance and inspect the AC unit periodically to confirm no sudden damage. If you notice any unwanted issues, handle them immediately to prevent further issues in the future. Hopefully, this post has helped you learn why rain is coming via your window AC.
