Ventless Air Cooling

People who live in hot climates can read this and find out about ventless portable air conditioners and other cool air solutions that both save money and bring welcome relief from the heat. There are more options than many people realize and these are worth exploring and highlighting.

While this blog focuses on the style of air cooling units that provide cool or cold air without needing to be vented to the outdoors, we'll also be covering other kinds of cool air solutions for hot climates. That means looking at air conditioning systems, portable units and alternatives that can both provide a cold air solution as well as bringing economical answers to the problems of rising power costs.

Did You Know..?

Top Rated Portable Vent Free Air Coolers

When you're looking for a great deal on the best portable air cooler models that don't require an exhaust vent that you can buy right now in 2016, finding this page was a stroke of good luck! That's because I know the secret to how to find the right cooling device that you really want and I'm going to reveal that secret below!

But first of all, I want to take stock of the most important aspects to you that I believe will define what is right in the perfect appliance to keep you feeling cool when it gets really hot outside.
  1. You want to feel comfortably cool where you are
  2. You want a healthy atmosphere to breathe
  3. You want to save energy and money
  4. You want a cooling device that does not need to be vented to the outside

We all know that a portable air conditioner will provide plenty of cold air, but a true AC needs to be vented to the outside and costs a lot of money to run because it uses a lot of energy. So a traditional portable AC is not really what you want, isn't that right?

That's why you came here in the first place: looking for a healthy, low cost alternative!

Let's take those points above and get some perspective.

Comfortably Cool

Being comfortable in all weathers is a natural human requirement that can easily be satisfied with modern appliances in the home or workplace. They include air coolers, heaters and ventilation systems that come in all kinds of configurations to suit individual wants and needs.

But you still want to enjoy all the benefits of AC with efficient air cooling but with economical power consumption and no exhaust pipe or hose to vent to the outside, right? Right!

For staying cool during summer, instead of expensive, unhealthy and cumbersome air conditioners, I focus on evaporative air coolers (swamp coolers).

These beautiful devices provide plenty of cold, moist air (which is better for healthy respiration) but only use a fraction of the energy consumed by power-hog ACs.

And they do not require an exhaust hose to vent anything to the outside. Perfect!

Healthy Breathing

A clean, healthy indoor atmosphere is what we all want to breathe, there's no arguing that one! A big downside to AC is that is dries the air, sucking all the moisture out of it. This can be tough on the delicate lining of our lungs and is especially tough on children, even though we think they're pretty resilient to these things when they're really not.

Evaporative coolers work in the opposite way to AC in this respect, by adding moisture to the air, not taking it away. This makes for a lung-friendly atmosphere and while we're about it, it's also very good for our skin and complexion.

Dry air has an adverse effect on our skin, aging and lining unnaturally if we're exposed to it for too long. Moist air is the opposite, hydrating and keeping it young and supple. I think I know which you'd prefer to have!


In this day and age, the way energy is being wasted while prices keep rising as natural resources are used up can upset a lot of people. It upsets me!

So I personally prefer to use appliances that are economical with their power consumption for all the right reasons. Swamp coolers typically use 1/20th the energy that comparable ACs use to provide the same level of cooling. That, for me is a sure winner and I'm pretty sure it will be for you too.

Portable Air Cooling with No Exhaust Vent

We all know that a portable air conditioner will provide plenty of cold air, but a true AC needs to have all the hot air it produces vented to the outside. So a traditional portable AC is not really what you want, isn't that right? That's why you came here in the first place!

Swamp coolers don't use compressors or refrigerating gases, so they don't produce any heat! None! They give you lots of chilled, moist air with no ugly exhaust pipe for a fraction of the running cost of air conditioning. And they're generally cheaper to buy!

So with the important stuff covered, I'm sure you want to see what I can recommend as, in my own opinion, the best swamp (evaporative) cooler on sale today for all the right reasons.

Best Free Standing Evaporative (Swamp) Cooler

In my experience, the top model non-AC air cooler is the Honeywell CL30XC. It has exceptional cooling power coupled with a big capacity and is super easy to use.

What Could Go Wrong?

With all the incredibly positive aspects to this type of cooler, you are probably wondering if there is anything bad about them and why doesn't everyone stampede to the hardware stores and buy them all up? Well, there is a disadvantage that limits their use depending on where you live.

Humid climates and evaporative coolers do not go well together. The higher the humidity, the less effective these devices are at producing very cold air.

They are therefore NOT recommended for areas with high humidity, but work best in naturally dry climates. So if you live in a place that has a very humid climate, I would not recommend you buy a swamp cooler but instead you'll need to budget for the increased running costs of a regular AC unit if you want to have that comforting coolness when it gets too hot to do anything else.

In these cases if you want a portable cooler, you are limited to a vented AC unit. That means having to connect an exhaust hose to a window venting kit or other custom wall vent and paying a bigger utility bill... but at least you'll be cool!

How to Vent a Portable Air Conditioner Without a Window

As you need to provide an outlet for the hot, moist exhaust air it produces, here's how to vent a portable air conditioner without a window present if you find yourself in that situation. This can happen with windowless rooms built into older apartment buildings where large rooms are divided into two or more smaller ones, for example.

In this article, I'm getting away from the kind of air cooler that doesn't need venting at all, namely the "evaporative or swamp cooler." The reason for this is that there are a lot of people who live in areas of very high humidity where they don't have the option of using evaporative cooling and an AC is their only way to stay cool when it gets really hot and humid.

Best Portable Air Conditioners to Use

There are several great room air conditioners available to buy that are perfect for venting via alternative means than a window if the need arises. Here are some of my top picks that can be bought online from Amazon:

Simply click the image of the unit that you want and you'll be transferred to the relevant page at the Amazon website.

Venting a Portable Air Conditioning Unit

So let's look at why you need to vent a portable AC in the first place and not just leave it to stand alone in a room turned on and sounding like it's doing what it should be doing. As I mentioned above, all AC units whether fixed or moveable produce a hot, moist stream of exhaust air as a by-product of the refrigeration process that is happening under the hood that you don't see.

There is no avoiding this, because that's how AC works!

Room temperature air is drawn into the unit where it is passed through the internal refrigeration process that acts in a similar way to a domestic fridge. A heat exchange mechanism works by chilling a refrigerant gas using a compressor and forcing that very cold gas through a series of fine tubes in a lattice, looking something like a radiator.

In fact, that's exactly what it is. The warm room temperature air is forced through the cold radiator and is itself chilled and dried. That chilled, dry air is then pumped out of the unit into the room by a fan.

The other side of that heat-exchange equation is the hot air produced by the compressor (mechanical energy) that gets mixed with the moisture that was stripped from the air passing through the refrigerated radiator. That has to be evacuated from the unit but not into the same room being chilled with the cold air, or it would cancel out the cooling effect!

So you can see it is not possible to have a true portable air conditioner without exhaust capabilities because that hot air must go someplace.

Getting the Unwanted Hot Moist Air Out of the Building

So that hot, moist air has to go outside the building for best efficiency. Normally, a portable AC would simply get hooked up to an available window fixing kit using the flexible plastic exhaust hose provided. But we have no window!

In that situation, there are still options, but they require some additional minor construction work to be done. In short, there needs to be a hole made in an external wall so the AC's vent can connect to it and exhaust the air through it to the outside.

That is often the simplest solution and provides a more aesthetically pleasing setup as the hose can be better concealed low down out of sight with the AC unit placed directly in front of the newly created wall vent.

Another solution is to use a false ceiling space to install an exhaust duct that runs to an external wall to provide an outlet for the unwanted hot air. This is more difficult and usually requires a professional installer to carry out the work.

Either way, you are provided with a means for exhausting the moist, hot air from the AC out of the room and building leaving you with a nice cool environment to relax in!
