Ductless mini-splits are a popular choice for heating and cooling systems in homes and businesses. While they are highly efficient and easy to install, you may notice your ductless mini-split leaking water at some point. Why is that? There are several reasons why a mini-split could be dripping water, and understanding the cause is essential to know how to fix it.
One of the main causes of a mini-split leaking water is a clogged air filter. When the air filter becomes dirty or obstructed, it restricts the airflow, causing condensation to form on the unit. As a result, water droplets will start to accumulate and eventually drip down onto the floor or furniture underneath. This problem is especially common during the summer months when the AC is running frequently.
Clogged Drain Line
Another common cause of mini-split leaks is a blocked or clogged condensate drain. The inside unit of the mini-split houses an evaporator coil that removes heat and humidity from the air. As the moisture condenses, it is collected in a drain pan and drained through a small PVC pipe. However, if this drain pipe is blocked or clogged, the water will overflow and drip onto the floor. A clogged condensate line can also cause damage to the mini-split unit and your property if left unaddressed.
A water leak from a Mini-split can also be caused by a frozen evaporator coil. When the unit is running, the evaporator coil absorbs heat from the air, causing it to freeze. When the coil thaws out, the water may drip down onto the floor. Frozen coils can be caused by several factors, including dirty air filters, low refrigerant levels, and faulty thermostats.
How to Troubleshoot a Mini-Split Leaking Water
If you notice that your mini-split is leaking water, it’s essential to take action as soon as possible to avoid further damage and avoid an increased electricity bill. Ignoring the problem could lead to the growth of mold or mildew, causing a health risk. Here are some steps to take when you notice a mini-split leak:
- Turn off the mini-split. Before doing anything else, turn off the unit to prevent further damage due to the leak.
- Locate the leak. Use towels and a wet vac to soak up any accumulated water and track where the leak is coming from.
- Clean the air filter. A dirty air filter could be the cause of the problem. Remove the filter and clean it.
- Check the condensate drain pan and line. Make sure the drainpipe is clear and free from obstruction.
- Check for a frozen evaporator coil. Leave the unit off and allow the coil to thaw. If the problem persists, you may need to call a professional to check if the evaporator coil is frozen.
Prevent Mini-Split Water Leaks
The best way to avoid mini-split leaks is to practice regular maintenance. Changing the air filters at least once a month reduces the chances of water leaks. Cleaning the condensate drain can also prevent blockages. It is also important to schedule regular maintenance checks with HVAC professionals to optimize the system’s performance.
