Is water leaking out of your heat pump a cause for concern? It depends on whether the water comes from outside condensation—which is a normal occurrence—or from the internal components of the heat pump itself. If it’s the latter, you should contact your HVAC technician as soon as possible.
In this post, our heating repair technicians at AAA Air Conditioning, Inc. discuss the different causes of heat pump leaks.
It’s normal for condensation to form on your heat pump’s outside unit while it’s extracting heat from the air outside and moving it into your home in heating mode. When your heat pump shifts to cooling mode, the condensation forms on the evaporator coils instead and drips into a condensate pan.
How to Tell if It’s a Leak
If you see more condensation than usual, there may be problems with your heat pump’s drain system or internal components. The usual culprits behind leaks are:
- Clogged drains – It’s not uncommon for mold and mildew to grow in drain pans and clog their openings. Leaves and other debris can clog the drain pan as well. There’s also the issue of clogs in the drain line causing leaks.
- Dirty evaporator coils – Dust and dirt that’s accumulated on the evaporator coils can prevent water from dripping into the condensate pan.
- Frozen evaporator coils – In the summer, if your heat pump doesn’t have enough refrigerant, ice may start to form on the evaporator coils. Frozen evaporator coils are problematic because they reduce your heat pump’s cooling capabilities, not to mention the ice on the evaporator coils can cause leaks inside the heat pump when it starts to melt.
Of course, the only way to know the exact cause of these heat pump leaks is to have your local heating repairman inspect it.
