Top 10 Best Ventless Air Conditioners For Your Home

There are a lot of scenarios where you might want to install an air conditioner but don’t have an outlet or a window for the AC’s exhaust vent. And this can be an issue for poorly ventilated spaces that require different kinds of AC units. To help you overcome this issue, today we are here with some of the best ventless air conditioners that have been picked as per these points:

• Type of Air Conditioner: Before anything else, you should first check the type of ventless air conditioner that you are getting. While there are many options in the market, the two primary ones include evaporation coolers and portable air conditioners, whereas the former is more budget-friendly. However, since portable air conditioners don’t rely on water for cooling, they are ideal in humid areas.
• Air Flow Capacity: If you are going with an evaporation cooler AC unit, you must check its airflow capacity to understand its performance. The airflow capacity of evaporation coolers is given in CFM and includes ratings like up to 2100 CFM or up to 3100 CFM, where a higher airflow rating results in better cooling.
• Cooling Capacity: If you are going with a portable air conditioner unit, you can get an idea of its performance by checking its cooling capacity rating. You will find a value in BTU where a higher value, like up to 8000 BTU, will perform better than up to 4000 BTU. Fortunately, almost all portable air conditioner units available out there feature an 8000 BTU cooling capacity or similar.

Apart from these points, you still need to consider more about ventless air conditioners. Because of the same, all the best ventless air conditioners discussed here have all their primary aspects and factors listed alongside them.

Buying Guide For The Best Ventless Air Conditioners

Whether you want an easy to install air conditioner unit or want something temporary to cool down your room, you should definitely consider getting a ventless air conditioner for the same. Since these types of AC units are quite easy to install, we have already discussed a few of the best ventless air conditioners earlier in this list.

And to help you easily differentiate between all these ventless air conditioners, all of them also have their major specifications and features explained next to them. In fact, if you still wish to learn more, you can simply go through this complete buying guide for the best ventless air conditioners:

1. Type of Air Conditioner

Starting with the basics, if you are in the market for a ventless air conditioner, you first need to check the type of air conditioner that you want to get. And even though there are many options available out there to choose from, you will primarily come across evaporative coolers and portable air conditioners. Taking a look at evaporative coolers first, they use water evaporation to cool down the air.

Because of this, they are much cheaper than traditional air conditioners. However, if the air in your area is quite humid, then an evaporative cooler might not work the best. On the other hand, a portable air conditioner uses a more traditional compressor unit for its cooling function which does make them a bit expensive. But they ensure that you get great cooling irrespective of your climate conditions.

2. Air Flow Capacity

Those of you who are on a budget or don’t have the need for a traditional air conditioner might want to go with an evaporative cooler. In that case, you will need to check the airflow capacity of your ventless air conditioner to get an idea of its performance. The airflow rating simply tells you about the amount of air your air conditioner is outputting, where a higher airflow results in better cooling in the case of an evaporative cooler. While buying an evaporative cooler type ventless air conditioner, you will primarily find airflow capacity ratings like up to 2100 CFM or up to 3100 CFM, where the latter will offer much better cooling performance.

3. Cooling Capacity

Moving on to portable air conditioners, their cooling performance is not determined by the airflow capacity since they use a traditional compressor for cooling. Instead, you need to check the cooling capacity of your ventless air conditioner, which is given in BTU. Similar to the airflow capacity rating, a higher cooling capacity rating of your portable air conditioner will result in better performance. As a result, a cooling capacity rating of up to 8000 BTU will result in much better performance than a cooling capacity rating of up to 4000 BTU. Thankfully, all of the ventless air conditioners given above have a cooling capacity rating of up to 8000 BTU, which should be plenty for most users.

4. Coverage Area

While both the airflow capacity and the cooling capacity ratings are a great way to get an idea of the performance offered by ventless air conditioners, these ratings are not comparable to each other. As a result, you should consider checking the coverage area rating of your ventless air conditioner. This tells you about the size of the room a given air conditioner can effectively cool down, which makes it a great way to compare evaporative coolers and portable air conditioners. While checking the coverage area rating of ventless air conditioners, you will find options like up to 150 square feet, up to 700 square feet, and even up to 950 square feet, which is excellent for large-spaced areas that need high-performance cooling.

5. Water Tank Capacity

As mentioned earlier, an evaporative cooler uses water for its cooling process. And this is done by using the water stored inside an inbuilt tank. However, as you keep using your evaporative cooler, this water will evaporate away and run out with time. For the same reason, you should check the water tank capacity of your ventless air conditioner if you don’t want to keep filling the tank again and again. Depending on the evaporative cooler that you are going for, it can include water tank capacities like 2 gallons, 7 gallons, and even 10 gallons, where a larger tank is always better.

6. Fan Speed Options

Even though this does not affect the cooling performance of your ventless air conditioner, the fan speed options can definitely affect your overall experience with a given AC unit. Apart from changing the temperature in portable air conditioners, changing the fan speed can be a great way to control either an evaporative cooler or a portable AC unit. Due to the same reason, most ventless air conditioners come with either 3 fan speeds or 5 speeds. While 3 fan speed options should get the job done, having more fan speed options does offer more versatility and better control.

7. Control Method

Talking about control, you may want to change the fan speed, temperature, pump function, timer, and many other things on your ventless air conditioner. And if you want to do the same, then you will need to use the controls of your AC unit. Although, not all ventless air conditioners out there have the same type of control panels. While entry-level ventless air conditioners only have onboard controls, higher-end units will offer you a remote control for easier and faster control of all the settings mentioned above.

8. Warranty

Even though it is highly important to ensure that you have a powerful and versatile ventless air conditioner, it is also equally important to ensure that your AC unit is also highly durable and reliable. Without the same, you may face all kinds of issues with your air conditioners down the line. Thus, it is always a great idea to check the included warranty period of your ventless air conditioners. Fortunately, almost all ventless air conditioners given above feature a 1-year warranty which should be plenty for most users. In fact, a few of them even come with a 2-year warranty period which is even better for long-term usage.

Best Ventless Air Conditioners – FAQs

1. Is it possible to use a ventless air conditioner in a room without a window?

Ans: Just per the name, a ventless air conditioner doesn’t rely on a window for venting out the exhaust air. You can simply vent out the exhaust air through a door or any other vents available in your room. And if you are using an evaporation cooler, then you don’t need to worry about the exhaust air at all.

2. How easy is it to install a ventless air conditioner unit?

Ans: If you are talking about evaporation coolers or portable air conditioner units, then you will be glad to know that all of them are quite easy and quick to install. Since there are no outdoor units to be installed, there is pretty much no installation required. You can simply get started with either of these ventless AC units without much hassle.

3. Can you cool a large-sized room using a ventless air conditioner?

Ans: To get a better idea of whether a given ventless air conditioner can cool down a large room or not, you should check its coverage area rating. And while portable air conditioners generally don’t have a high coverage area rating, evaporation coolers can easily handle large rooms without any issues.

4. Is a ventless air conditioner going to be energy efficient?

Ans: Starting with evaporative coolers, since they use water instead of a compressor for the cooling mechanism, they are highly efficient. As long as you are not in a humid environment, they will cool down your room with quite high efficiency. On the other hand, a portable air conditioner is going to have quite a poor energy efficiency rating since they don’t have an external compressor unit.

Conclusion

In case you are not able to guess by the name, a ventless air conditioner does not require an exhaust vent like a window or an external cooling unit. Instead, these ventless air conditioners either use a different cooling method or a different design for the exhaust vent. Because this makes such AC units highly versatile, we have already talked about the best ventless air conditioners earlier in this list.

And to make sure that you are going with the right one, all of these ventless air conditioners even have their key features, and options explained along with them.

Beginner’s Guide to Ventless Portable Air Conditioners

What Is a Ventless Portable Air Conditioner?

A ventless or portable ventless air conditioner is great for those that need a portable air conditioner without window access, thus allowing for self-contained operation and much more freedom of placement and mobility. They can effectively cool smaller spaces, and since they don’t require any venting, they’re usable in areas that would require cutting a hole in the wall to install a model with a venting system or exhaust hose, saving you the installation time that even the best window air conditioners require. Though units like the best dual-hose air conditioner can effectively cool a space quickly, the installation involved with the dual-hose design is more time-consuming than a ventless unit.

They can vary in terms of cooling capacity, size, operating noise, filters, fan speed, additional features like auto-timer, programmable timer, and sleep mode, and efficiency from model to model, but they all work by cooling indoor air with water, instead of using a refrigerant cycling process like in conventional models. This is great because you won’t need to be constantly checking for a freon leak in your air conditioner.

There are a few variations on this basic design, but while they’re an effective option, they’ve got more than a few major differences from other air conditioner types. Instead of relying on a traditional air conditioner that uses a cooling system to provide an artificially generated cool breeze in any indoor space, evaporative coolers can offer a more natural and energy-efficient alternative. While you’re at it, you may want to look at other specialized types of models, such as window air conditioners with heat.

Ventless Portable Air Conditioners vs Other Models

A ventless portable air conditioner differs from a window unit in many ways, but the most significant difference is that the latter needs a window or vent to run its air conditioning cycle. Window ACs draw warm, humid indoor air and cycle outdoor air in, cooling it via an evaporator coil cooled by a refrigerant. It’s a highly effective way, especially in the best small window air conditioners of both cooling space and dehumidifying it, which is why it’s called an “air conditioner.” But, if your A/C is bringing in hot air, then you’ll need to repair the air conditioner condenser.

By contrast, the reason why ventless portable models aren’t considered “air conditioners” in the technical sense is that they don’t cycle fresh air into a space, and they usually don’t have a dehumidifier function that helps dehumidify the air that’s being cooled. While it’s an effective method of lowering room temperatures, it adds moisture to the air, which may be a plus for users living in a dry climate but not a good choice for people in humid climates. Still, it could be a problem for people sensitive to humidity.

Ventless portable units also differ from standard portable models for the same reason: other portable models require a window to function just like stationary, conventional air conditioners, and like traditional units, they dehumidify the air to varying degrees. Lastly, ventless portable units are much simpler appliances: they don’t have components like compressors or evaporator coils and often have a very simple display panel with few options. Some have casters that makes transporting them much easier like the unit in our Hessaire MC37M review.

The main advantage of a ventless model is that you can cool spaces that can’t otherwise have air conditioning through standard air conditioners. Specifically, they are perfect for windowless rooms, like many garages, basements, and other small, enclosed spaces. If quiet operation is a priority for you, know that while the actual noise level of ventless portable models may be lower, the fact that they stand freely in a room means you’re more likely to hear them over window-installed units, like an air conditioner for sliding windows.

How Ventless Portable Air Conditioners Work

Ventless portable air conditioners work significantly differently from conventional window, wall-installed air conditioners, or central air conditioning systems. A ventless unit has an open tank at the bottom that contains a refillable water reservoir, leading to a cooling pad above.

A fan first draws in warm indoor air while a pump sends water to the cooling pad from the reservoir. The fan blows the indoor door air across the cooling pad, picking up the moisture from the reservoir. The cooled, moist air is then sent back out into the room, cooling the room to the ideal temperature. Some models can cool the air by as much as 30 degrees.

Where conventional units dehumidify a room while cooling it, ventless portable units make the air more humid, to varying degrees of comfort. While effective at cooling a personal space, as a rule, they’re less efficient than conventional units. Their main advantage is that they can cool windowless spaces that otherwise couldn’t accommodate an air conditioner. You can read our Luma Comfort EC111B review to check out an option that is ideal for rooms up to 250 sq. ft.

Why Should You Buy A Ventless Portable Air Conditioner?

If you’ve got an enclosed, windowless area such as a garage, basement, office space, or workshop and you don’t mind missing the dehumidifying effect of conventional air conditioners, a ventless unit is really the main option you have available to you. Though it is possible to invest in a multifunctional unit that can both cool and dehumidify like the model we discuss in this VOSAREA Portable Evaporative Air Cooler review.

The actual portability of ventless, portable units varies from model to model. It decreases in higher-BTU (or British Thermal Units) models because of their increased size and power demands. But if you’ve got more than one space that’s windowless or that only occasionally needs cooling, having a ventless portable unit can serve as a good backup or complementary option to your home.

Keep in mind that, while there are ventless units in the 15,000 BTU class (designed to cool spaces up to around 900 square feet), they aren’t as common as conventional models in this class, meaning you’ll pay a premium for the most powerful ventless models.

If you have a very large windowless space of over 700 square feet, you might want to consider a wall-installed unit, which will require cutting a venting space in your wall but will give you the benefit of a conventional unit’s superior efficiency, performance, and better price-performance ratio.

Is a Ventless Portable Air Conditioner Worth Buying?

• You have a small to medium-sized windowless room to cool: The primary advantage of ventless portable AC units is that they don’t require a window or through-wall vent to work. So, for cooling a windowless space like a garage or basement, they are an excellent choice. But the bigger the room, the more BTUs you’ll need to get the job done, and high-BTU ventless models can be very pricey. Now if there does happen to be a window in your small space, a vented model like the one in this Shinco Portable Air Conditioner review can handle cooling the space too.
• You have multiple rooms that only occasionally need cooling: Though the degree of mobility or portability of ventless units varies considerably between models, they can be a good option if you’ve got more than one room that only occasionally needs cooling or need a versatile backup cooling option for your home.
• You have a larger budget and need to cool a large windowless space: Basements and other spaces that may be windowless can be fairly large. High-BTU ventless models can come with a fairly big price tag and aren’t nearly as efficient as conventional units. But if you’ve got the budget for it, they’re still an excellent option for a windowless 700-900 square foot space.

Why a Ventless Portable May Not Be For You:

• You are sensitive to humidity: Ventless air conditioners work by cooling warm air with water and sending it back into the room, meaning the cool air is high in moisture. Contrast that with conventional air conditioners, which dehumidify rooms while cooling them. If you’re used to the dehumidifying effect of a conventional model or you’re sensitive to humidity, you’ll want to keep this in mind. While there are some ventless portable models available with a dehumidifier function like the model featured in this Whynter ARC-143MX review, they’re uncommon and far pricier.
• You have a large windowless space to cool on a limited budget: If you’ve got a limited budget to play with and a large windowless space 700 square feet or bigger to cool, you should know that high-BTU ventless units tend to be fairly expensive in order to effectively cool larger spaces. Combine that with the fact that even the best ventless portable models are far less energy efficient in general than conventional models and can increase your power bill considerably with regular use, and you might find a wall-installed traditional unit may be a more cost-effective and practical option if the more complication installation process isn’t an impediment. Another option to fit into a smaller budget is to create your own portable DIY air conditioner.
• Your carbon footprint and energy efficiency are a primary concern: If you are looking for energy savings, ventless portable AC units are far less energy-efficient than conventional models, as a rule, meaning more energy consumption and a bigger carbon footprint if used regularly. Even a ventless model with high EER (Energy Efficiency Ratio) ratings and Energy Star certification will be less efficient than a conventional model with a lower EER and no Energy Star sticker.

How Long will a Ventless Portable Air Conditioner Last?

Given their significantly lower energy efficiency than a conventional window unit, it may be somewhat surprising that ventless portable air conditioners have an average lifespan of around 5-10 years, which is only a little lower than conventional models.

Several factors can affect a unit’s lifespan:

Frequent Moving

Ventless portable units are often made of more lightweight, cheaper material than conventional models, making them more fragile and susceptible to wear and tear. If you’re using one frequently in multiple spaces so that it’s getting moved around a lot, the wear and tear increases, which can potentially shorten its lifespan. However, if you need to easily move the unit around your space, you should consider a model like the one in our Luma Comfort EC110S review that has caster wheels. In addition, the compact design makes storage easy when not in use.

Heavy Use

Frequent use for sustained periods will greatly increase wear and tear, and the humidity they create as they cool rooms can also take a toll on various components, all of which can significantly reduce the lifespan of a unit. Cleaning a unit’s built-in filter regularly can help mitigate the effects of heavy use, however. It’s important to keep up with regular maintenance of the unit along with repairs, such as learning how to unclog an AC drain line. Maintaining the unit involves keeping it in good shape and clean, so we highly recommend you learn how to clean a portable AC unit.

How to Choose a Ventless Portable Air Conditioner

Now that you’ve decided to purchase a ventless portable air conditioner unit, consider a few additional factors and features that will help you choose the right model for you.

Best Ventless Portable Air Conditioner Key Factors

1. What size room do you need to cool?

The cooling capacity or cooling power of ventless portable AC units is rated using BTUs, just like in conventional models, so the BTU rating of such units indicates the room size it’s designed for with the same ratios. A ventless strong 5000 BTU air conditioner unit is designed for 100-150 square foot rooms, etc. Knowing your room’s exact dimensions is crucial to picking a unit with enough power to do the job. Even if your room is a compact size and you get a high BTU unit, it might wind up working overtime if you use consistent cooling, so it’s best to find the sweet spot BTU rating. If you have a large room and want to conveniently control the unit without having to get up, consider something with a remote like the model in our Honeywell CO30XE portable review.

2. Is efficiency the most important factor for you?

Just like with conventional models, ventless units have two standardized measures of energy efficiency recognized by the EPA and the U. S. Department of Energy, and knowing them will tell you which models will save you the most on your power bill.:

• Energy Efficiency Ratio: The Energy Efficiency Ratio rating or EER indicates BTUs per watt of power. A higher rating means a more efficient unit. For ventless portable models, the U.S. Department of Energy recommends an EER rating of 8.0 or higher- lower than the EER rating recommended for conventional models, because ventless units are far less efficient as a rule.
• Energy Star Certified: The presence of an Energy Star sticker or emblem on an air conditioner indicates it’s guaranteed to use a minimum of 10% less energy than models of comparable power. The majority of U.S. states also offer rebates on Energy Star products, incentivizing the choice even more.

3. What’s your budget?

Ventless, quiet portable air conditioners are often more expensive than conventional models of comparable power and quality, and the difference in price raises significantly the higher the BTU rating. If you’re looking to cool a windowless space that’s 700 square feet or bigger, you’re going to be looking at 12000 BTU units or higher. For smaller spaces, stick with something like the Costway portable air conditioner.

Combine the high initial cost with the considerably higher energy costs due to their low efficiency, and you may want to consider a wall-installed conventional model instead. It will be a more complicated installation, but you’ll get more bang for the buck and a lower power bill. Some come with easy-to-follow installation kits like the best 12000 BTU air conditioner.
