How to Vent a Portable Air Conditioner | Sylvane

How to Install Your Portable AC with a Window Kit
Most portable ACs are simple to install and vent using the manufacturer-provided window kit.
 
A standard window kit includes a window bracket, one or two vent hoses, and the vent hose adapters. The average vent hose extends 4 to 5 feet, so you need to install yours close to a window. Follow these steps to quickly set up your portable AC: 
Steps 1-3: When venting a portable air conditioner, attach any hose connectors/adapters and insert the hose (or hoses).
Steps 4-5: Extend the adjustable window kit the length of your window. If necessary, trim the window bracket to fit your window snugly. Your specific model may come with screws to keep the window kit in place. Then close your window to secure the kit in place.
Step 6: Next, connect the vent hose to the window kit. With your model properly installed and vented, you can start cooling immediately. Just plug it in and program your settings. It's that easy!
Note: Customers often ask if they have to remove their window screen to install a portable air conditioner. More often than not, you don't need to remove your screen. 
Replacing Portable Air Conditioner Window Kits
If you're looking to replace a window kit for your model, check out our Portable Air Conditioners Accessory page . It's best to get one from the AC's manufacturer, but chances are you can find one that fits your needs. 
One of our most popular window kits is the Honeywell Portable AC Replacement Kit . It fits standard double-hung windows between 20 and 47.25 inches wide, and the exhaust hose is 5 inches in diameter.

Sliding Window and Sliding Door Ventilation
 
Standard window brackets are designed to be installed horizontally at the bottom of windows, but they can be installed vertically to fit sliding windows and sliding doors. Some modifications of the window bracket may be required.
For sliding windows, you need to make sure that the bracket will be long enough to fit the opening. Units that feature double window brackets generally work well for sliding windows. A double bracket includes the standard window bracket plus an additional filler bracket. After setting up the bracket, if there's still an opening, you can fill it with wood, Plexiglas, insulation, or some other type of filler material.
When working with sliding doors, the window brackets will not be long enough to fill the vertical opening, so you'll need to fill the extra space with some other material like plywood or Plexiglas.  Browse our most popular portable ACs for sliding windows or doors .
Casement Windows
Since casement windows and crank windows open like doors, standard window kits will not fit them. But that hasn't stopped our resourceful customers. Many customers who have casement windows simply cover the entire window opening with Plexiglas and cut out a hole for the exhaust hose. 
Drop Ceiling Ventilation
Electronic equipment can produce a great deal of heat, but sensitive equipment must be kept cool at all times. Portable ACs are extremely popular for computer server rooms, since they can cool the warm equipment to avoid overheating and other issues. The only problem is server rooms rarely have windows and are usually away from exterior walls.
Fortunately, most office buildings have drop or panel ceilings. Many portable air conditioners, like those from KwiKool , can be configured to vent into drop ceiling spaces.
Wall Ventilation
Some people prefer to exhaust hot air through a wall vent, directly outside or to another room, such as a garage or storage room. You can use a jigsaw to cut the correct size hole in the wall—but make sure there isn't any wiring or plumbing where you want to cut the hole. You can seal the edges of the hole with silicone caulk.
Connecting to Dryer Vents
In most cases, using a dryer vent to exhaust a portable air conditioner isn't recommended. Dryer vents have a 4-inch diameter, and most exhaust hoses are slightly larger in diameter. DeLonghi portable ACs , on the other hand, feature 4-inch exhaust hoses, so they would fit most dryer vents. However, if the external opening of the dryer vent contains a flap, then the unit's hot air exhaust will not be strong enough to push it open. In this case, you would need to remove the flap and replace it with a screen.
Do Not Extend Vent Hoses
You should not try to extend the vent hose during portable air conditioner venting because it will result in decreased efficiency, and it could also void the warranty.
