Why Is Water Running Out of My Ductless HVAC System?

Many homeowners in Galveston, TX, have chosen to cool and heat their homes with ductless HVAC systems because they’re efficient and easy to install. These systems usually run reliably for years, but there are problems that can cause them to leak. Let’s take a look at some of the issues that could cause your mini-split to leak water.

Damaged Drain Pan

The moisture that a ductless mini-split system removes from the air inside a house is deposited in a drain pan. If you notice water accumulating around a mini-split system that’s more than five years old, the source of the problem could be a damaged or rusted drain pan. This is why certified HVAC service technicians inspect mini-split system drain pans closely when they perform routine maintenance.

Clogged Condensate Line

Water that gathers in the drain pan flows into the outdoor unit via a drain pipe called the condensate line. If this drainage line becomes clogged with dirt or debris, the drain pan will eventually overflow. A clogged condensate line is the most common cause of mini-split system leaks.

Dirty Air Filter

Pools of water under a ductless HVAC system’s indoor unit are sometimes caused by a chain of events set in motion by a dirty air filter. When air filters become clogged with dirt that restricts the airflow, ice can form on the evaporator coil. When the coils warm up, the ice melts and water drips onto the floor. Clean your ductless HVAC system’s filter every month to avoid this issue.

Most of the problems that cause water to leak out of ductless HVAC systems could be prevented by performing regular maintenance tasks like checking drain pans, clearing condensate lines and replacing air filters.
