What is a Portable Air Conditioner?

Check out the Youtube video, or scroll below for some quaility content

 
There are no portable air conditioner units with a window kit that will work for a casement window. Some customers have fashioned a solution using plexiglas to cover their entire window area and then have a small hole cut into the plexiglas for the hot air discharge hose. No solution is provided “out of the box” but some customers have fashioned their own.

What is the difference between a single hose design and a dual hose design?

Single Hose System

Pros: Single hose unit will have a high EER rating then the single hose and does not draw as much power because it only has one motor and more fresh air

Cons: A single hose cool the condenser by pulling the air from the room they are cooling, and then this air is expelled through their exhaust hose. This creates the negative pressure in the room, in which hot air is continually seeping into this room you are trying to cool from the rest of the house or building to replace the air that the portable AC expels, so that effective cooling capacity is reduced, and slower initial cool down

Dual House System

Pros: Dual hose unit work with one hose intakes outside air to cool the condenser and another hose to expel this air A two hose unit can cool the room air quicker than a single hose unit, approximately 2~3 times faster depending upon the room size and outside temperature . Also a two hose unit can achieve energy savings since it can reduce the compressor from continually running as it circulates cool air inside the room.

Cons:

1) Same air circulating within the room, which will decrease in oxygen and increase in carbon dioxide.

2) If outside temperature is high (>90°F) or when humidity is high (>80%), compressor cannot be cooled and results is increased temperature of front air output. In such cases, the second hose should not used to prevent the compressor from overheating.

3) Uses two internal fans and consumes more energy due to added hose.

Do I have to remove my screen from the window?
The answer to this question may vary based upon your particular window and screen. However, most of our customers find that they can leave the screen in the window and that the exhaust hose of the AC does not extend out from the window.

How do I use the window venting kit? Does it fit my window?
The window venting kit is essentially a “filler” kit to allow the end of the exhaust hose to vent out the window without allowing hot air from the outside in around the vent hose. The window vent kits fit most windows and glass doors that slide to open (this includes sliding glass doors and windows that slide both vertically and horizontally). These units do not come with a filler kit to fit casement (crank-out) windows, but with a little ingenuity, you should be able to devise some sort of filler kit

How long is the exhaust hose that the portable air conditioner comes with?
Exhaust hose lengths vary by model, but generally they are 4-5 feet in length. They are made of a temperature-resistant plastic reinforced with metal.

Installation / Set Up

Requirements will vary based upon the model. However, all portable air conditioner units exhaust hot air as part of their cooling process. This hot air is typically directed out of the space being cooled through a hot air discharge hose. This air hose is often vented out of a window, through a wall ( like a dryer vent) Do not installing a unit into a drop ceiling, attic. Or plenum or an adjacent space. A Portable A/C is exhausting hot saturated air which can leave the other spaces wet clammy, and more susceptible to mold

The window venting kit is essentially a “filler” kit to allow the end of the exhaust hose to vent out the window without allowing hot air from the outside in around the vent hose. The window vent kits fit most windows single or double hung windows and sliding windows for sliding glass doors you will need two window kits, for Casement “ crank out” style windows sorry there really is not a good way to install it a window kit for this style window.

Set Up :

Portable air conditioners come with installation instructions and kits for installation into windows. Here are a few tips for what a standard installation might entail. Of course, you should follow the installation instructions that come with your portable air conditioner.

Location
this is one of the main advantages of portable air conditioners- they can be installed in many places that other air conditioners cannot. However, the easiest installation is into a standard sliding window. Due to the design of the venting kit, it is equally easy to install one of these units into a standard double-hung window or a side-to-side slider window.
