Should You Buy a Windowless Air Conditioner?


With winter on its way out, the weather will soon start to grow steadily warmer, and with it comes the necessity of a good air conditioning unit, or else slowing roasting in one’s own home. However, not all air conditioners are made equal, and you may find that there is a wide variety of designs and functions available for you to choose from. In this case, we’ll look at windowless air conditioners and the question of whether or not they’re worth purchasing.

Windowless Air Conditioners

In short, a windowless air conditioning unit is an AC that doesn’t have to be attached to a window. As one may have already grasped by the name. But what does that mean exactly?

Most air conditioners work by drawing in warm air from a room and replacing it with cooler air. The cooler air is then blown into the room, lowering the ambient temperature. Usually in this process, the warmer air has to be expelled somewhere, and window-fitted AC units blow it outside through the back of the unit. Windowless air conditioners, however, don’t remove hot air in this way.

Instead, hot air must be funneled out of the room by some other means. One way is for the hot air to be expelled from the unit through a length of tubing. Some owners may reroute the air into the space under the floor or above the ceiling, some into another unoccupied room. Sometimes a window still ends up being the best route, with some other means to direct the flow thusly.

At any rate, the compact size and windowless fitting does carry with it some interesting quirks in character.

What’s Bad?

The main issue I tend to hear with windowless air conditioner units is that they’re not as efficient at cooling a room as larger models, simply because they can neither draw in as much warm air, nor expel it as efficiently. The tube with which warm air is pushed out of the warm is usually no more than five inches wide, as opposed to conduits that might be a foot or two in diameter.

As such, some may find them inadequate for the purpose of making a room more inhabitable during particularly warm summers. As most rooms where AC units are most often used tend to be fairly large, such as lounges or kitchens, its size often works against it. The lack of efficiency also means it’s something of an electricity guzzler in proportion to its size. You may find that what you save in purchase price, you end up losing in energy costs. If that’s the case, you might want to check with a professional AC installer like Bob Heinmiller in Orlando to see if a full-home air conditioning system would be a better choice for your energy costs.

What’s Good?

Meanwhile, the main advantage to a windowless AC is that it’s easy to install. Larger, window-bound units have to fitted into the window and its frame, and may sometimes require additional support outside the window as well to prevent it from slipping out. A windowless AC unit doesn’t require nearly as much prep work, and the majority of models simply need the tube to be directed somewhere for the warm air to deposited. This makes it a lot more convenient to buy and install, especially if your accommodations don’t easily allow for other options.

It also makes the AC unit portable. If you decide to retire from the living room to a bedroom, it’s a simple matter to unplug and reposition a windowless air conditioner. Window-fitted models don’t have that luxury.

Finally, windowless units are nowhere near as much of an eyesore as larger models can be. Indeed, in most cases people walking outside may not even realize you have air conditioning at all until they’re close enough to see the tell-tale exhaust tube. So they’re a great way to cool a room without ruining its external appearance, or blocking the light from a window.
