Not every home comes standard with air conditioning. For example, in the Pacific Northwest, a built-in cooling device has never seemed necessary because of the region’s mild weather. That’s why portable air conditioners bridge the gap between a fully air-conditioned house and a totally non-air-conditioned home to keep summer heat manageable. They also reduce the levels of humidity inside your home during the hot, humid summer months. Keeping the heat and humidity under control lessens the chance of allergic reactions or asthma attacks. Here’s our recommendations on how to install a portable air conditioner

Portable air conditioners should not to be confused with window units. Portable components don’t need permanent installation, don’t require holes in the walls and aren’t expensive. Select a window with a close proximity to an electrical outlet because most of the standard vents are 5 feet long. Or you can vent the unit through a wall, ceiling or door. For the sake of simplicity, we’re going to install the portable air conditioner through a window.

7 Step Guide for Installation

Step 1:

Before installing your unit, unpack the portable air conditioner and set it upright for at least two hours so the refrigerant inside settles.

Step 2:

Remove all the parts in the package and make sure you have everything you need before beginning the installation. If any part is missing, including the window slider kit—an attachment to the kit that fits the hose—an exhaust, small screws, a remote control or drainage hose, then call the store or manufacturer and have the omitted part sent to you.

Step 3:

Hook the connectors to the exhaust hose. Usually the hose will rotate straight into place. You should now have an airtight seal.

Step 4:

With the window open, place the window slider kit on the inside rim of the window. Change the width so it fits the window. You may or may not have small anchoring screws that will let you tighten the slider in place. Now close the window to further secure the slider.

Step 5:

Take the exhaust hose from step 3 and connect it to your air conditioner. You may have plastic tabs that line up and then it will either snap or twist into place.

Step 6:

Position the portable air conditioner a few feet from the window. Connect the exhaust hose (if you need to lengthen it, pull gently) to the opening in the window panel fixture. Depending on the model, the hose should lock, twist or snap into place.

Step 7:

Plug in the power cord and prepare to cool off. If your unit has a reset button, now is the time to push it. Then turn on the power. If the unit isn’t working refer to the troubleshooting portion of your installation manual.
