When your ductless air conditioner suddenly develops cooling problems, your comfort goes down. Fixing inefficient cooling and airflow issues from your ductless HVAC system requires an HVAC expert. Here’s why your ductless AC has cooling issues in your Oro Valley, AZ, home.

Low Refrigerant Levels

Unnoticed refrigerant leaks are among the most common causes of poor air conditioning. These leaks could remain undetected for months if you fail to perform routine inspection on your ductless HVAC system.

Essentially, the refrigerant carries away excess heat from your indoor atmosphere. Usually, ductless HVAC systems recycle the refrigerant compound during normal operations. If your system has an undetected leak, the remaining refrigerant levels are insufficient to sustain your home’s air conditioning.


Another reason behind poor cooling is dirty air filters. Debris and dander along the HVAC air filters inhibit air circulation within your home. Additionally, dirt buildup causes the ductless HVAC components to exert more force to bring your home to the desired cool temperatures.

Clogs along the condensate lines similarly hinder efficient air conditioning. Typically, ductless HVAC systems have longer condensate lines than ducted AC systems. Consequently, ductless AC systems are more susceptible to blockage.

You should always check your system’s air filters every month. A ductless HVAC maintenance plan is also helpful to ensure clean condensate and refrigerant lines.

Evaporator Coil Issues

Problems within the ductless system’s evaporator coil could also cause gradual malfunction. The evaporator coils take in hot air from the indoor atmosphere, enabling proper circulation of cool air. Frozen evaporator coils are unable to absorb the excess heat from your house.

Notable reasons behind frozen coils include dirty filters, short-cycling and low refrigerant levels. Consult an HVAC specialist if you spot water puddles along your ductless system.
