Is a Ductless Mini-Split a Good Option for Heating?

That depends entirely on what you’re looking for. Ductless mini-split systems have a few pretty good advantages over more traditional systems, but they also aren’t a one-size-fits-all solution. Read on to find out if a ductless mini-split is right for you.

Distinguishing Features

Unlike a lot of other heating systems, ductless mini-splits are installed on an outer wall. The outside part of the unit absorbs thermal energy from the surrounding air, while the inside unit circulates warm air into the room. Essentially, ductless mini-splits are heat pumps. The difference between them and other heat pumps is their lack of ductwork to distribute air. A ductless unit will only heat the room that it is currently installed in.


The first advantage you should know about ductless mini-splits is that they are remarkably energy efficient. The unit only has to heat one room, so it doesn’t have to waste a great deal of energy heating up the rest of the house before reaching the target temperature. This can save a lot of money on heating bills.

By eschewing ducts, the ductless system also avoids losing any of its heat in transit from the unit to the room. Duct systems lose between 20 and 30% of their heat on average to duct leaks, so avoiding that issue is a significant advantage.

If you’re using multiple ductless systems in your house, you will have the unique ability to set different temperatures for each room. Each ductless mini-split is operated by its own thermostat, allowing each member of your house to set a temperature for their room that is most comfortable for them.


The biggest strength of ductless systems is also their greatest weakness: you can only heat one room at a time per unit. If you have a smaller space you want heated, or you plan on using multiple units, this isn’t really a problem. For larger houses, though, it’s something you should consider.

Ductless systems also tend to be very prominent, needing a lot of wall space for installation. Some may find this an eyesore.
