Ductless heating and cooling systems, popular for years in Japan and Europe, are gaining ground in the U.S. They offer many benefits — from versatile mounting options to clean, quiet and efficient operation. One of their most appealing uses is for ductless zoning. Here’s what it is and how it may benefit your home.
How a Ductless System Works
Ductless systems are heat pumps that move heat outdoors in summer to cool and indoors in winter to heat via refrigerant. Also called ductless mini splits, ductless systems have an indoor evaporator and air handler, as well as an outdoor condenser and compressor connected by a flexible conduit with refrigerant lines and wiring. Some systems can operate as many as four air handlers, making it fairly straightforward to create zones within the home by placing the air handlers strategically.
By creating zones within the home, homeowners have more control over temperatures in separate spaces. The results are a greater comfort and more efficient operation. With a ductless system, you can cool or heat rooms you use most and save energy in rooms that are used less frequently, such as a guest bedroom. Just as you wouldn’t want all the lights on in your home, you wouldn’t want every square foot of your home heated or cooled equally if the entire home isn’t in use. Ductless zoning gives you that opportunity.
With a ductless system, you just have to choose where you want your air handlers located. Typically, one might be in a living room, one in the kitchen area, and a couple more in bedrooms. An added advantage of a ductless system is that the air handlers can be mounted almost anywhere in the room, including on the ceiling, floor or the wall.
