Ductless mini- and multi-split systems are comprised of a single or multiple, wall-mounted indoor units linked to a compact outdoor compressor. The units are lightweight, quiet, with a slim profile and incorporate into nearly any space. Providing both heating and cooling capability, ductless heat pumps are fairly simple to install and require little more than a small hole in an exterior wall and access to electricity. Most professional HVAC contractors can complete the installation project in a manner of hours. There’s no need to tear down walls or deal with major mess or renovation. Because the ductless system simply moves heat between the indoor space and the outdoors, it provides energy efficient temperature control. Plus, the majority of modern ductless systems feature inverter technology, which allows the equipment to adjust speed to meet demand. This avoids continual start up and shut down and achieves more evenly distributed temperatures. Despite the small size, ductless units are surprisingly powerful and can typically heat up or cool down a large room to the ideal temperature within a matter of minutes. With a tap of a button on a cordless remote, or even your smartphone, you can regulate temperature, fan speed, and even humidity levels. With the added bonus of advanced air purification, most ductless heat pumps effectively filter out contaminants such as dust, dander, mold and germs, for superior indoor air quality. Because of the individual air handlers in each room, you are able to customize temperature to personal preference and avoid heating/cooling empty rooms, for further cost savings. While the purchase and installation of a ductless system is rather expensive, the ductless unit will typically pay for itself in energy savings.
