How to Cool a Room That Does Not Have Air Ducts

If you’re looking to air condition a room that currently doesn't have AC (like a new addition, garage, craft room, man cave, or Arizona room), we highly recommend ductless mini-split AC systems.

Why? Mini-splits work better than window air conditioners and are easier than renovating your current central AC system.

Let's take a closer look at why...

How a mini-split is different

Like a regular central AC split system, mini-splits have 2 components, an inside unit and an outside unit.

However, unlike a typical system a mini-split system needs no ductwork to cool your home. The mini-split’s indoor unit is mounted right where you need cool air—usually on an interior wall near the ceiling in the room that needs cooling—eliminating the need for ducts.

Key advantages over cooling options

This set-up has many advantages for room add-ons and other rooms where you want to add on. Here are a few…

Easier and less costly installation

No ductwork means easier professional install. The only space required is a small hole for the copper tubing and control wiring between units. No need to re-run all your ductwork.

Also, your AC system’s ducts are perfectly balanced for your current home. Therefore, you can’t simply add ducts onto existing runs, you have to retrofit most of your existing ductwork.

Depending on the design of your home, the overall cost of retrofitting your ductwork can range between $7,000 and $10,000.

Energy efficient

Without ductwork, there’s zero chance of money draining air leaks.

Safer than window units

Window air conditioners can be an easy point of entry for burglars. Plus they can be just plain ugly sitting in one of your windows. Mini-splits elegantly blend into your wall and are more out of sight.
