3 Common Ductless AC Issues and How to Fix Them

Whether you’re building a new home in Palm Desert, CA, or you’re remodeling an older home or putting on an addition, a ductless air conditioning system is a wise choice. With no leaky air ducts to waste energy, these systems deliver precision comfort at an affordable price. Like other air conditioning systems, it’s possible to experience an issue once in a while. Be aware of these three common ductless AC issues that your system could develop.


There are two types of leaks that can occur in a ductless air conditioning system. Because these systems have multiple indoor units, they’re prone to refrigerant leaks. If you hear a hissing sound from the indoor unit, leaking refrigerant is a likely cause. Ductless air conditioners can also have condensate leaks. The condensate line drains the condensed humidity in the form of water. The line goes from the indoor unit to the outdoors. You might notice dripping water from the conduit. Both of these issues require professional attention.


According to the Department of Energy, short-cycling is a common issue that could require a ductless AC repair. Short-cycling often results from a dirty air filter. Ductless air conditioners typically have reusable filters. The filters need to be cleaned every two to four weeks. Short-cycling can also result from an air conditioning system with too much capacity. When installing a new cooling system, our technicians perform a cooling load calculation in order to select the right capacity for your home.

Faulty Blower Fan

The indoor unit contains a fan. The fan is responsible for blowing the cooled air into your living space. A faulty fan may stop spinning. It usually results from an overheated motor or an electrical issue. You’ll need a ductless AC repair for a faulty fan.
