Understanding the possible reasons for RV AC leaking water inside
An RV AC may leak water for multiple reasons. Let’s look at each of them:
-
Condensation buildup:
RV AC units create condensation like any other air conditioner. Water is usually collected in a drip pan and sent outside the RV. If the drip pan is stuck or cracked, water may flow inside. Remove dirt from the drip pan and clean or replace it.
-
Clogged drain lines:
RV AC drain lines remove condensation. Dirt, debris, or algae can block these drain pipes, causing them to leak water. Check the drain lines and clean any clogs with a hard brush or compressed air.
-
Improper installation:
An improperly placed RV AC unit might tilt wrongly, allowing water to pool instead of drain. To avoid water leaks, in that case, contact a professional for repositioning and leveling the unit.
-
Frozen evaporator coils:
Due to low refrigerant or limited airflow, AC evaporator coils might freeze. Water may flow inside your RV when these coils thaw or freeze. Make sure the AC unit has sufficient airflow, clean the air filters on a monthly basis, and have a professional examine and restore the refrigerant if needed.
Remember, to avoid damage and ensure your RV AC functions work properly, you must consider seeking expert support for RV AC repair if you’re not sure how to fix or solve the problem.
Understanding RV AC leakage causes and fixes makes your camp comfortable and dry.
