After reading this blog post, you will be able to fix all your AC leakages. Let’s quickly start by understanding how RV ACs work.
How RV ACs Work?
An RV air conditioner is designed to cool down the interior of an RV. The system consists of a refrigerator, compressor, condenser, and evaporator. First the air passes through evaporator coils which cool the air. Then there is a compressor having a special liquid which absorbs the heat from the air. After this, this liquid then moves to condenser coils, which release the heat outside. Finally, the cool air is blown back into the RV to keep it cool.
RV ACs vary based on space, size and other parameters of your RV. There are two main types of ACs: Ducted and Duct-less. Duct ACs are used for larger units, which have several ducts on the ceiling, while ductless ones are used for smaller RVs. Ductless ACs are usually installed in the window or the top of the Rv.
RV AC Leaking Water Inside
RV AC dripping water outside is normal; however, RV AC water leaking inside can be very problematic. It could cause disturbances by making your bed or other things wet and affect your comfort.
You may observe water drops or puddles on the floor coming from the air conditioner. Timely diagnose the leakage and fix it to avoid further damage. The first step after noticing the leakage is identifying its cause.
Common Reasons For RV AC Leaking Water Inside
Dripping of water from the AC inside the RV could be due to several reasons. Let’s check out all of these in detail below to understand them better.
Clogged Or Blocked Drain Line
The first common cause of RV AC leakage on our list is a Clogged drain line. When the drain line is blocked, the drain pain might not work properly. As a result, the water will fill up and start dripping inside.
Broken Components
The second reason for RV AC leaking water inside is broken components. Check out all parts, including the motor, condenser coil etc. If any of these parts is damaged or not functioning properly it could also be responsible for water leakage inside.
Improper Installation
The following cause for dripping water inside is improper installation of the air conditioner. If you have recently installed your RV AC or got it repaired, this leakage might be due to improper installation as well. Basically, it happens when your drain pipe is not attached properly or drain holes are not being properly routed to the pan.
Dirty Air Filter
The last cause on our list is a dirty air filter. When the filter is blocked it stops the air from flowing properly. This makes it hard to remove the moisture from the AC. It also causes the water to drain inside.

Fixing AC leakage timely is also essential to avoid further problems during your journey. After identifying the cause of a leakage, the next step is to fix it. You may be able to fix the minor or easy leakages on your own, while for the other, you might need the help of a professional mechanic. Below are the solutions for the common causes of RV ac dripping water inside.
Clearing a Blocked Drain Line
The most common cause of RV AC leakage is a blocked drain line. Start by climbing onto your RV to locate the drain line. Inspect it for any visible dirt or debris. Use a vacuum to remove the particles if it’s blocked. Clearing the blockage will allow water to flow out of the drain line properly and prevent leaks.
Fixing Bends in the Drain Line
The next solution is for leakage due to bends in the drain line. Check your drain line for any bends or kinks. Carefully straighten the line with the help of pliers. This will help the water move through the line easily.
Inspecting and Repairing the Drain Pan
Another potential source of RV Air Conditioner dripping water inside is the drain pan. It is located directly below the evaporator coil. Remove the evaporator cover to access the drain pan. Inspect the pan for any cracks that could be causing the leak. If you find any, then repair or replace it and recheck your AC.
Cleaning the Drain Pipe
The next fix on our list is clearing the drain pipe blockage. Remove the evaporator cover and check the drain pipe. You should be able to see through it; if not, then it’s probably blocked. Use a vacuum to suck out the dirt and clear the pipe.
Once you’ve fixed the issues, finally turn the AC on and check if there is still any leakage. If the problem persists then you need to visit a professional mechanic.
Reinstalling The AC Unit
If the RV AC leaking water inside is not fixable or has a very high fixing cost, then you may need to reinstall the AC unit. Especially if you have an old RV, then we would recommend you reinstall it to avoid further problems. It may be costly but it will save you from continuous repairs. Coleman Mach 15+ is the best RV air conditioner in 2024 according to Forbes. You can buy it in $980.00 from Amazon.
