If you own a ductless air conditioner, you may wonder what to do when your ductless air conditioner starts to leak. Various things, including clogged condensate lines, an overcharged system, or a loose fitting can cause leaks. No matter what the cause is, there are some simple steps you can take to remedy the situation and get your air conditioner back up and running. Here are 10 ways to help you get your ductless air conditioner back up and running after it starts to leak.

1. Condensate Line

A clogged condensate line is the most common cause of a leak in a ductless air conditioner. Check the line for any clogs or debris that could be blocking the flow of water. If the line is clogged, try using a wet/dry vacuum to remove the blockage.

2. Drain Pan

Look underneath your air conditioner to see any water in the pan. If the pan is full, it could mean a problem with the pipe carrying the water away from the air conditioner.

3. Refrigerant Lines

If your air conditioner is leaking refrigerant, it could be due to a loose fitting or an overcharged system. Check the lines for any loose connections and make sure that the system is properly charged.

4. Filter

The filter of your ductless air conditioner can become clogged over time, which can cause the system to overheat and possibly lead to a leak.

5. Seals

If your air conditioner is leaking water, the seals around the unit are loose or worn out. Inspect the seals around the air conditioner to see if they are loose or have any signs of damage. If they do, replace them to ensure the air conditioner is properly sealed.

6. Area around the Air Conditioner

The area around the air conditioner can become clogged with dirt and debris, which can reduce the efficiency of the system and cause it to leak. Clean the area around the unit to ensure proper airflow and reduce the leak risk.

7. Drain Line

If water is coming out of your air conditioner, it might be because the drain line is clogged and not allowing the water to drain properly.
