If you notice your heat pump leaking water indoors, you know that it’s not functioning properly and needs some attention. You should address the issue as soon as possible to prevent further damage to your heat pump or home. Your first step should be to turn your heat pump off using your remote control. There are a few common causes for a leaking indoor unit. It’s important to figure out which of the problems you’re having so you can get the equipment repaired to start heating and cooling your home more efficiently again.


Dirty Heat Pump Coil

The source of your heat pump leak could be as simple as a dirty coil. There’s a cold evaporator coil in your unit that removes condensation from the air then drains it out of your heat pump. If this coil gets dirty, it can interfere with the draining process. Instead of going down into the drain, moisture can run off of your evaporator coil and create a leak. The solution here is as easy as getting a professional inspection of your heat pump to see if it needs a thorough cleaning.

Frozen Evaporator Coil

The evaporator coil can freeze if your refrigerant levels are too low. Low refrigerant in heat pump systems can lead to a buildup of ice inside of your system. When the ice melts, you might see water leaking out of your heat pump. Frozen coils prevent your heat pump from doing its job effectively, so you may notice a spike in your energy bill in addition to the water running out of your heat pump. A professional heat pump technician can remove the ice and add refrigerant to your ductless to prevent further problems.

Condensate Drain Clog

Heat pumps naturally collect moisture from the air and expel it through a condensate drain system. Over time, this drain can become clogged by a buildup of dirt, algae, or other debris. When the drain gets blocked, water will build up in your heat pump and start to leak out of other places. Your heat pump may even shut down when the drain becomes clogged. Professional maintenance will solve this problem.
