Why is My Camper AC Dripping Water

Are you enjoying a summer road trip in your camper but wondering why your AC is dripping water? Don’t worry, we’ve got you covered! In this article, we’ll explore some common reasons why your camper AC might be dripping water and provide some simple solutions to fix the issue.


Condensation is the most common reason why your camper AC might be dripping water. Just like any other air conditioner, when warm air passes over the cold evaporator coils, it creates condensation. This condensation usually collects in a drain pan and then drains outside your camper through a small tube or pipe.

However, if this drain system gets clogged or the tube becomes disconnected, the water will not be able to flow outside, resulting in water dripping inside your camper. To fix this, check the drain pan and the drain tube for any blockages or leaks. Clean the pan and ensure the tube is properly connected, allowing water to flow outside.

Frozen Evaporator Coils

If you notice water dripping from your camper AC, another possible reason could be frozen evaporator coils. When the evaporator coils freeze, they can produce excess water, which then drips into your camper instead of collecting in the drain pan. This can occur due to low refrigerant levels, restricted airflow, or a malfunctioning thermostat.

First, check your camper’s thermostat and ensure it’s set to the appropriate temperature. If that doesn’t solve the issue, inspect the air filter and clean or replace it if necessary. A dirty or clogged filter can restrict airflow and cause the coils to freeze. If the problem persists, it’s best to seek professional assistance to check for refrigerant leaks or other underlying issues.

Excessive Humidity

In hot and humid weather, it’s natural for an AC unit to generate more condensation. If the humidity levels inside your camper are high, the AC might produce more water than usual, causing it to drip. This is especially true if you’re consistently entering and exiting your camper, introducing warm and humid air.

To reduce excessive humidity, you can use a dehumidifier or portable moisture-absorbing products inside your camper. Additionally, ensure your camper is properly sealed to prevent outside air and humidity from entering. Installing window or vent covers can also help regulate humidity levels and prevent water from dripping.

Incorrect Installation

If you recently installed a new AC unit or had maintenance work done on your camper’s existing AC system, improper installation could be the root cause of the water dripping issue. It’s crucial to ensure that the AC unit is installed correctly, including proper placement and secure connections.

If you suspect incorrect installation, it’s best to consult a professional HVAC technician who specializes in camper AC systems. They can assess the installation and make any necessary adjustments to prevent water drips and maintain optimal performance.

Regular Maintenance

Prevention is always better than cure when it comes to camper AC issues. Regular maintenance of your AC system can help prevent water dripping and other problems. Cleaning or replacing the air filters regularly, inspecting the drain pan and drain tube for any blockages, and ensuring proper airflow are essential maintenance tasks.

Additionally, scheduling annual professional maintenance for your camper’s AC unit is highly recommended. A certified technician can perform a thorough inspection, detect any potential issues, and address them before they lead to water dripping or other AC problems.
