The 11 Best Mini Split Ductless AC | The Ultimate Guide

There are various benefits of ductless mini splits but the main advantages are their flexible zoning ability, size, and precise cooling of individual rooms. Moreover, you can find many ductless ACs that allow up to four indoor air handling units for one outdoor heat pumping system. So, you can cool up to four rooms with a single ductless mini split – how cool is that?

And if you have more rooms or zones to cover, you can simply add more mini splits to support more indoor air handlers. We recommend consulting your AC installer to best indoor handler configuration to optimize the temperature of your home.

Regardless of whether you have one or more than one indoor air handlers, they’re all connected to the outdoor unit by components called the ‘line set.’ To form this connection, your AC installer will drill a hole (about two or three inches in diameter) in the exterior wall. This helps the line consisting of copper tubes and electrical wires run between the components.

You can also find tubes and casts in local hardware stores to hide these lines in case you’re worried about messing up the aesthetics of the exterior wall.

Air conditioning systems with ducts are responsible for significant energy loss during the cooling process. Central air conditioners that utilize multiple ducts for circulating cool air often face this issue, and require frequent sealing of the ducts to maintain efficiency. Using ductless splits will eliminate AC ducts altogether, so you won’t need to worry about high energy bills or sealing them every other year.

Ductless units are also constructed with energy efficient components and technology that further help you save money and energy while cooling your home.

All ductless mini splits come with built-in control panels that allow you to seamlessly adjust the temperature and utilize different settings. They also have remote control technology with each indoor air handler unit, so you set each zone at a different temperature remotely.

These methods of control are much more efficient than the traditional thermostat control found in central air conditioning systems.

Compared to central HVAC units and portable systems, ductless mini splits are pretty quiet. Air moving through multiple ducts at high speeds can make a loud noise, but since these units are ductless, there’s no chance of that happening. That’s why people who prefer a quieter home environment most often go for ductless splits.
