Window AC vs Ductless Mini-Split: Which Is Best for My Add-on Room?

Below are the pros and cons of each type of air conditioning system at a glance.

Pros:

• The unit itself is not expensive (most window ACs range from $150 to $400)

• The labor to install the unit is minimal because it does not require an HVAC technician (meaning you can install most window ACs yourself)

Cons:

• Noisier than a ductless mini-split system

• Blocks out an entire window, which limits the amount of light in the room

• Is poorly insulated, meaning a lot of cold and hot air can escape via the window

• A potential security hazard (thieves can steal the unit or remove it to enter your home)

• Typically costs more to operate than a ductless system

Pros:

• The indoor unit is small, which means it can be placed almost anywhere in your room

• Quieter than a window AC

• Generally costs less to operate than a window AC unit (a ductless system uses about 30% less energy than any other type of room AC)

• Adds value to your property

Cons:

• Higher equipment and installation cost (the cost to install a ductless AC ranges from $3,200 to $8,000)

Window ACs are often sold directly to consumers without needing to be installed by a tech—which means the buyer is usually responsible for fixing the unit if it breaks down.

So if you consider yourself fairly handy, and you’re on a tight budget, a window AC might make the most sense for you.

By design, window units are meant to be a temporary cooling solution. So if you’re planning on staying in your home for several years it is probably a better idea to invest in a ductless system.

Since ductless systems cost less to operate, you’ll save money on your monthly energy bills which will lead to long-term savings.

If you’re renting, you might consider a window unit because a mini-split system might be too great of an investment.

On the other hand, if you own your home, a ductless AC can add to your home’s overall value
