A ductless mini split air conditioner uses the same type of refrigerant cycle that all air conditioners use, but it doesn’t require ducts to distribute cooled air—and remove warm indoor air—from the interior of your home. Instead, the indoor air handler/evaporator unit is compact and sits directly within the living space, often high on the wall, or recessed in the ceiling. It connects to the outdoor unit by a set of electrical, refrigerant, and drainage lines. Let’s take a look at some of its benefits:
- Energy efficiency. Because of its compact design and lack of ductwork, the ductless mini split air conditioner can have a SEER (Seasonal Energy Efficiency Ratio) rating of up to 27, which is much higher than forced air distribution systems. Ductwork can account for up to 30% energy loss, depending on their size, location, and condition, so ductless systems excel in energy efficiency.
- Performance. Ductless mini split air conditioning systems combine efficiency with performance. Because of the location of the indoor air handler, it often achieves a faster response time to temperature adjustments than conventional systems.
- Zone control. One of the perks of a ductless system is that it has a built-in zone control system. While you can retrofit a central air with dampers and thermostats, you can typically have up to 4 indoor air handler units for every outdoor condenser/compressor. With that type of control over various areas of your home, you can see why it has become a popular alternative.
