Mini-splits are innovative AC units that completely eliminate ductwork from the home. Instead, they function via an outdoor compressor and interior air handler, which are connected by a small cable. Although these systems are efficient, it's important for homeowners to be aware of the common problems that can affect these devices. Here are a few things to look out for. 

What Problems Can Affect Mini-Split AC Units?

1. Strange Odors

Musty odors coming from the equipment usually mean an issue with mold growth. In this case, there may be an obstruction in the drain line that's causing water to get trapped inside the equipment. If you detect an odor similar to vinegar, you may have a refrigerant leak. Refrigerant absorbs heat from the air before it can be dispersed around your home. Refrigerant leaks also have a drastic impact on function, so they require immediate service. 

2. Drips and Leaks

Faulty drain lines can also cause other issues. Under ideal circumstances, the drain line will take accumulating condensation in the AC and deposit it outside the home. If a defect develops somewhere in the tubing, you'll find leaks and dripping water around the unit. 

Leaks are a major issue, as they can damage home fixtures or even contribute to mold growth. Fortunately, lines can be replaced for improved function. 

3. Bothersome Noises

Mini-splits tend to be rather quiet, so if you hear a cracking or gurgling noise from the unit, that means it's entered into defrost mode. If you hear this noise repeatedly, you could have an issue with the electrical controls. Devices can also make a clicking noise, which is typically caused by internal plastic components expanding and contracting. However, cracking could also mean a component has broken and is now loose inside the device.
