On those hot summer days, it can feel pretty stuffy being stuck in an RV without any air conditioning. It’s even worse when it starts dripping water, and you’re wondering if it’s broken and you have to get a new one. Why is it doing that?

There are several reasons why your RV air conditioner might be dripping water. It could be due to rain water, a clogged drain hose, or an overflowing drain pan. Thankfully, they should be easy problems to resolve.

In this guide, we take you through everything you need to know about why your RV air conditioner might be dripping water and the quick fixes you can implement to get back to normal.

Why is Your RV Air Conditioner Dripping Water?

Why is Your RV Air Conditioner Dripping Water

There is nothing worse than moist air and humidity when you’re stuck on the road. An RV air conditioner leak can REALLY mess things up.

If your RV air conditioner has started dripping water, there are a FEW potential causes. Thankfully, they tend to be fairly easy to fix, so you should be back in action in no time.

Rainwater

One potential cause of water dripping from your RV air conditioner is rainwater. If there is a lot of rainfall, the water can SEEP through the RV roof and into the AC unit itself.

If you think this might be the case, it’s best to check the SEALS around your RV’s roof and windows to ensure they are still intact and doing their job. You can also invest in an RV cover to help keep the water OUT.

Pro Tip: Even a newly installed air conditioner can fall victim to the rain, so check it regularly.

Overflowing Drain Pan

Another potential cause of RV air conditioner leaks is an overflowing drain pan. The pan is designed to HOLD any water that drips from the AC unit as it’s running.

However, if there is a problem with the drain pan, it can start to OVERFLOW past the drain holes and cause water to drip onto the floor (or wherever else the pan is located).

One way to prevent this is to ensure the drain pan is the right SIZE for your RV air conditioner. You should also regularly check it to ensure there is no debris blocking the drain hole.

Condensation

Another potential cause of dripping water from your RV air conditioner is condensation. When the AC unit is running, it can cause the surrounding air to cool down and reach the DEW POINT.

At this point, water vapor in the air will start to CONDENSE and form droplets of water on the AC unit itself. These droplets will eventually start to drip down, causing the water-dripping problem.

Pro Tip: An air conditioner removes moisture from the air, so a leaking air conditioner is not going to be pumping cold air back into the RV.

One way to prevent this is to make sure the RV is properly ventilated. You can do this by opening windows and doors when the AC unit is running.

Clogged Drain Hose

Another potential cause of dripping water from your RV air conditioner is a clogged drain hose. The drain hose is responsible for REMOVING any water that drips from the AC unit.

However, if the hose becomes clogged, it can cause water to start building up and eventually start DRIPPING out.

One way to prevent this is to regularly CHECK the drain hose by removing the rubber gasket and clearing any debris that might be blocking it.

Faulty AC Unit

Finally, a faulty AC unit is another potential cause of dripping water from your RV air conditioning system. If the AC unit itself is damaged, it can cause water to start leaking out.

This is usually due to a problem with the evaporator coil OR the condenser coil. If you think this might be the case, it’s best to take your RV to a professional for further diagnosis and repair.

How to Tell if Your RV Air Conditioner is Broken

  • The AC unit isn’t blowing cold air

If you notice any of these signs, it’s BEST to take your RV to a professional for further diagnosis and repair.
