How to Install a Portable AC in a Crank Window

The process here varies slightly depending on the make and model of your air conditioner and the overall dimensions of your crank window, like when you are learning how to install a ductless split air conditioner.

Insider Tip

There are installation kits for just about any type of window out there, even sliding doors for those really in a pinch. Shop around and you’ll find what you are looking for.

STEP 1 Measure Your Window

Start by measuring your window and purchasing the appropriately-sized Plexiglas insert.
Jot all of these measurements down for later.

STEP 2 Cut the Insert

The insert needs to be whittled down to size to fit your crank window.
This requires serious tools, so bring the insert to your local hardware store and have them cut it down to the correct size.
Make sure they also cut a hole for the vent hose.

STEP 3 Begin Installation

Now that you’ve got the insert, start the installation by opening the crank window and attaching a latch to the window as well as the frame.
Use retainer clips or twist clamps to secure the insert to the window frame.
Secure weatherproofing strips to seal the insert and keep it waterproof.

STEP 4 Attach the Hose

Now that everything is secure, affix the hose to the vent.
Plug the portable air conditioner into a power outlet and turn it on.
You should experience cool air flowing from the air conditioner.
Enjoy the cool air and bask in the security of a job well done.

F.A.Q.S

How to choose and install a portable AC window seal?

This depends on the size of your window panel and the size of your actual window unit. Measure before doing any work.

What is a casement window?

Casement windows operate on a hinge, much like crank windows. They lack a traditional window frame but are energy efficient.

How to vent your portable air conditioner?

You can vent your AC in a number of ways and the same goes for central air conditioning, a slider window air conditioner, and a vertical window air conditioner.

STAT: Portable A/C is a bit more complicated than an evaporative cooler of the same size, however. In addition to being plugged into a power source, they should also be vented for optimal efficiency. (source)
