In the past, an addition, office, garage or other living space without access to ducting was kept cool by loud, unsightly window and floor units. The noise almost made the conditioned air not worth it. Maybe you’re thinking, “I still use a window unit.” Well guess what? Those days can be over with a ductless air conditioning and heating system!
Normal residential HVAC systems are called “split systems” because the equipment is split up between inside and outside the home. A ductless system is called a “mini-split” because it too operates in a split system design. A ductless air conditioner or heat pump sits outside the home, and a ductless air handler is mounted inside on an adjacent wall (or recessed in the ceiling).
A ductless air conditioning and heating system offers quiet, efficient comfort that is pretty surprising. The indoor air handlers are designed to condition a specific room, but more than one indoor air handler be run from a single outdoor unit. This offers room by room comfort control, without the need for ducting or the noise of portable units.
This manufacturer owns the majority of the ductless heating and air conditioning market. Mitsubishi ductless products for both residential and commercial are tough to beat. Highly efficient, reliable and backed by great warranties. In fact, the standard 10-year compressor warranty on Mitsubishi ductless systems is higher than Daikin, Fujitsu, LG and Panasonic. Mitsubishi ductless solutions offer all of the traditional desired installation types including wall, floor or ceiling recessed indoor air handlers. Various Mitsubishi ductless outdoor unit models can power multiple indoor units, and they also boast H2i® Technology which allows a ductless heat pump to heat even down to sub-zero temperatures.
Another popular manufacturer of ductless air conditioning and heating solutions is LG. In our opinion, LG’s indoor air handlers look a little better than Mitsubishi. So of course, you’ll need to chat with your HVAC contractor about efficient ratings, sound levels and other items before making a decision based just on looks. Another cool thing from LG in addition to their already slick-looking air handlers is their Art Cool™ option. LG Art Cool uses a ductless air handler that’s designed to look like a painting on your wall. Not bad right? For unobtrusive comfort, LG Art Cool is worth a look.
Fujitsu pushes ductless efficiency over 27 SEER which is pretty impressive! They’ve been a long-standing player in home comfort, and continue to manufacture quality ductless solutions. Fujitsu Halcyon® ductless air conditioning and heating solutions can power up to eight indoor air handlers from a single outdoor configuration! that means you could use this solution to implement zoning in your home. All of the manufacturers listed here offer some level of multiple indoor to single outdoor ratio, but Fujitsu Halcyon definitely is not last on the list!
Daikin also sells millions of systems worldwide, and is definitely another trusted leader in the ductless mini-split space. One notable thing about Daikin: their standard warranties can be bumped to 12-year compressor and parts with a 6-year labor warranty. Now that’s pretty cool. And like other manufacturers above, they feature inverter technology for high efficiency comfort. Their units also sense if you leave the room, and after 20 minutes will auto adjust comfort in order to not waste money.
