How to Stop RV Air Conditioner from Leaking Water into Your RV
I have a 1998 Coachmen Catalina. When I turn my air conditioner on, water drips through the filter.Shop Camping World Products on Sale Now!
ANSWER: Hi Bill since you did not mention that your RV A/C unit is leaking when it is raining I am going to assume that the problem is that the drain pan on your RV's Air Conditioner is not draining properly and allowing the water condensation from the evaporator to leak inside of the RV rather than draining on the RV's Roof like it should.
I would first suggest that you clean or replace the interior air filter on your RV's air conditioner.
Dirty evaporator coils could also cause this problem. Either way, you are going to have to open up the Air Conditioner to fix the problems.
If you are comfortable going on the roof of your RV, you can check the evaporator and the drain pan on your RV's Air Conditioner. To do this, you will have to remove the shroud on the Air Conditioner and remove any cover attached to the evaporator. These covers are normally held on with several screws.
Once you access the drain pan, check the drain pan for any blocked drain holes. Also, check to make sure that no one has sealed around the drain holes of the Air Conditioner, thinking they were fixing a leak.
Take a look at the coils on the evaporator; if they are dirty use a product like Formula 409 Cleaner
to thoroughly clean the coils.

If after you have completed the steps outlined above and you still experience leaking problems with the A/C running or you have had water leaking from the A/C when it rains then the problem is probably the gasket
between the roof of the RV and the Air Conditioner unit itself.
If the Air Conditioner Gasket needs to be replaced, I would suggest that you take the RV in and have a Certified RV Technician replace the gasket and inspect the roof around the A/C unit opening for any structural damage as a result of the leak.
I hope this helps.
