One of the big selling points of a ductless mini-split is the fact that you can create a zoned heating and cooling effect using several air handlers. A single outside unit is connected to several air handlers, each one supplying warm or cool air to a room or section of your home. If you want a cool living room but somebody likes their bedroom a bit warmer, you can crank up the AC in the living room without affecting bedrooms. If you have a three-room mini-split, you can set three different temperatures in different parts of your home.
It’s important to understand that there are limits to what a multi-zone mini-split system can do. While you can find a four-room mini-split, larger systems are more expensive, and installing several air handlers requires more work.
A ductless mini-split is a basic type of heating and cooling system, often including a single outdoor unit and a single air handler. Multi-room ductless mini-split systems, on the other hand, include several air handlers and are designed to provide heating and cooling for larger spaces. As a matter of fact, there are even five-room mini-split systems if you want the ultimate zoned heating and cooling effect.
Keep in mind that a multi-zone mini split system needs a line run from the outdoor unit to each air handler, in addition to more air handlers have to be installed. Aside from a larger upfront investment for the unit and air handlers, expect to spend more for a multi-zone system installation.
As far as installing a ductless mini-split multi-zone system goes, installation costs can vary quite a bit. First, it depends on how many air handlers you plan on having installed, as each air handler adds more time and money. You also have to consider how many feet of line you’ll need to run to attach each air handler to the outdoor unit, as this line typically costs about $5 per foot.
On average, it costs about $4,000 to install a ductless mini-split AC system. However, it’s important to remember that your installation could cost significantly less or significantly more. If you’re not sure whether a multi-room ductless air conditioner is the right heating and cooling solution for your home, make sure you talk to an HVAC technician before you invest in an expensive unit.
