Ductless Mini-Split

Why is My Ductless Mini-Split in Cherry Hill, NJ, Leaking Water?

September 22, 2021

Ductless mini-split systems are a great way to heat your home during the winter in Cherry Hill, NJ. Due to their zone climate control and quiet operation, it can be very easy to forget that yours is operating — until there’s a leak. If your ductless mini-split is leaking, read on to find out why and what you can do to resolve the issue.

Defrost Control

Have you noticed that your outdoor condenser is leaking water? The reality is that most of the time, this will be due to the defrost control setting on your system. When the outdoor condenser coils get too cold during the winter, your ductless mini-split system will heat them up for a short period to melt the ice on the coils.

Refrigerant Leak

It can be very easy to think that a leak coming from your wall-mounted unit is water. Actually, it may be refrigerant that’s leaking out of the coil. If you notice the leak is near your refrigerant line, it’s best to call in one of our professionals to handle the leak, as refrigerant can be dangerous when it’s not handled correctly.

Frozen Condensate Line

Your ductless mini-split has a condensate line that moves water from the inside to the outside of your home. Whenever this line sticks out too far or the temperatures get too cold, it can cause the water in the outer section of the pipe to freeze. This can cause any new entering water to back up into your indoor unit as it can’t make it past the frozen part of the pipe.

Clogged Condensate Line

Another reason that your pipe may not properly drain water is that the condensate line has a clog. As your system runs, it’s not uncommon for debris to get caught up in the pipe from time to time. It’s best to pour a bleach and water solution down the condensate line every couple of months to keep it free of debris buildup or have a professional perform regular maintenance on your system.
