Best Portable Air Conditioner So you have this one room in your house that’s just way too hot to handle, but there’s no way to install an air conditioner in the window. Well, as luck would have it, the best Portable Air Conditioners are lifesavers for just this situation. There are pros and cons here, such as it’s great to have a machine on wheels that will make any room cold. But they need to pump out all that hot air with a hose which needs to be connected to a window or exhausts outside. So windows and access to the outside are still required.

Unlike the air conditioner window units we are all familiar with, many building regulations do not allow their use. The great advantage of portable air conditioners is that all the mechanical parts actually sit in the room, although they do need their space in order not to block the air flow. While some may be large and heavy, they are on wheels and portable once you want to move them. Be sure to install the hose and window vent well in order to keep the hot air from leaking back into the room.

Benefits of Portable Air Conditioners

Benefits of Portable Air ConditionersA portable air conditioner is what it sounds like, a fully functional air conditioner that you move around. It stands on the floor in a room instead of sitting in a window and is meant to cool one room or space at a time. They can be easily moved from one room to another because they sit on wheels, making these units an excellent option in comparison to window units.

If you don’t know which type of air conditioner is right for you or your home, we will present some of the options for your consideration. Price is certain to be high on the list, but there is more than just price to consider. So let’s go in with an open mind towards making an educated decision.

Who Buys Portable Air Conditioners?

Since portable air conditioners can be moved around from room to room, home to home, or office to office, these are popular purchases for homeowners, renters and business owners alike. These units work well in any environment, and some are so good at reducing moisture and condensation, they have become popular additions in machine and server rooms.

Cooling One Room at a Time

Central air and large window air conditioners take a huge amount of electricity to operate. And as we all know, that means a pretty hefty bill at the end of the month. Part of your financial planning may be to install central air in only the larger rooms of your home, like the living and master bedroom, and leave the smaller rooms or less used rooms for portable air conditioners.

Many portable air conditioner models are eco-friendly and operate more economically than other methods of cooling. This option provides cooling everywhere you need it, while minimizing the cost. For times when you are home alone and need to little cool relief, charge up the portable, grab a nice cold iced-tea, sit back and relax knowing you’re not busting your budget.

Controlling the Room Environment

In hay season do your allergies or asthma make sleep a distant memory? Most serious allergy and asthma sufferers need cool, dry, optimized air to get a proper sleep. Most central air units do not address these needs well, nor do you want to run them all night.

Setting up a portable air conditioner in your loved one’s bedroom will provide just the right relief from air-borne allergens with a mix of dehumidification, air filtration, cooling and freshening. You can set the unit in sleep mode to run all night at just the desired temperature without freezing out the entire house or floor.

If you have a few children, they probably all like their rooms different temperatures. Blasting central air would not only waste money, it would not solve the problem. Placing portable air conditioners in the room or rooms of those who love the cold, brings affordable peace, relief and quiet to your home.

Easy-Breezy Installation

Portable air conditioners do not require building codes, holes in the wall, special electric plugs or extra phases of electricity to operate. All you need to do is hook up the 4″ hose to the back or top of the machine and vent the hot air from the inside to the outside, usually through a window. Installing a portable air conditioner requires a few simple steps and you can even move it around and install it in another room without damaging the window or the hose.

For offices and server rooms, there are venting kits to specially install these units through doors and drop down ceilings so the heat can get outside properly.

Energy Efficiency

Whereas energy consumption of portable air conditioners varies by model, they do come in many sizes with suitability for different spaces. You can find the right sized model for your needs and chose a portable air conditioner that has solid energy efficiency ratings. Do your homework and check the energy requirements on the package or in the description in your online store.

Since portable air conditioners work best in single rooms at a time, they enhance your energy efficiency in comparison to operating a central unit when only needing to cool a specific room. You can use a small energy efficient portable unit to keep your room cool, making it a smart energy saving choice.

Disadvantages of Portable Air Conditioners

There are some solid and useful benefits with portable air conditioners, but with the good always comes some disadvantages. Some portable air conditioners need to be drained more than others, the purchase price can be higher than window units and they are not always efficient in cooling a room.

The Water Needs to Drain

Some portable air conditioners need frequent or constant draining, especially when using the dehumidifier. If you think about it, the moisture pulled from the air has to go somewhere. Some portable air conditioners have a tank included that would need to be emptied on a regular basis.

To overcome the drainage problem, you can a purchase a unit with auto-evaporation that basically does away with manual draining. Or some models allow you to plug a small hose into the water out take, that will take the water out without any more manual intervention. Keep this in mind when you do your research, because if you live in a hot and humid environment, in some homes, draining the water will be a constant issue. The best auto-evaporation models that mostly hands off cost a bit more, so you will have to decide which is best for you.

The Cost of Buying a Portable

Price is definitely an issue with portables in comparison to window units. When you have the choice and ability to install a window unit and price is your primary concern, window units can be had for far less investment. But that has not deterred the huge upsurge in demand for portable units. Mobility, simplicity, cool features and reputable manufacturers have made portable air conditioners a major category in the sector.

Portable air conditioner models start around $300 and can range all the way up to $1200 for top of the line, premium models, whereas smaller window units can start as low as $150. The advantages of portables, such as heating in the winter, motion sensing and dehumidifying provide extra features along with the higher prices.


BTU for BTU, some people think that portable air conditioners don’t measure up to the efficiency of window units. This may be true in many cases as window units don’t have to compensate for the enclosure and safety requirements of indoor operation.

Deciding Between Portable and Window Air Conditioners

Deciding Between Portable and Window Air ConditionersWe buy air conditioners for one primary reason, to defeat the elements in order to stay cool. Whether its portable or window-mounted, the final result needs to be a cool and comfy room while getting the most energy efficiency we can. In order to achieve the best results, there are a number of issues to think about in deciding which type of air conditioner to buy.

Window Air Conditioners

Window air conditioners have been an extremely popular and affordable way of cooling homes and offices for many years and have been hard at work for much longer compared to portable units. In most cases all you need to do it place the unit in an available window, extend the plastic side panels for the best fit and plug it in.

Problems Installing Window Units

Window air conditioners are made to standard sizes only and will not fit in non-standard sized windows or small windows. If your unit is large, most people will find it difficult to install and would not be possible as a one-person operation. Larger units also require the installation of a bracket system to support the bottom of the machine. In some cases this is quite difficult and if you rent, the landlord may not allow this installation. The downside of all window air conditioners in any case is losing the use of a window.

Can I install a Window Unit?

In many cases you simply have no option of a window unit, whether because of building codes and beauty, rental contract requirements or non-standard windows. In this case, you will find the best portable that suits your needs.

How much space is available?

One of the first considerations is space, or how much of it you have in your room. If you are severely limited, you may consider a window unit, since it does not sit on the floor and is always out of the way. But if you have the space and don’t want to kill your window, a portable unit can be perfect for you.

How large is your room?

In an average size bedroom, a relatively small window unit and a normal sized portable would suffice and work quite well, under normal conditions of use. In larger rooms, such as living rooms and basements, larger units would be necessary. A primary problem in cooling most living rooms is air leakage if there are no doors that can be closed or stairs that draw the air away. In these cases, the precious cold air can escape, meaning your unit will operate longer and it would be harder to maintain ideal temperatures.

What Size Portable Air Conditioner Should I Go For?

What Size Portable Air Conditioner Should I Go ForLike all other air conditioners, the common unit of measurement of power for portable air conditioners is BTUs, which stands for British Thermal Unit. As a unit of energy, you can think of it like this; a four-inch wooden kitchen match, completely burned, generates about 1 BTU.

Size definitely matters when it comes to BTU cooling power. The more your unit has, the more room it can cool. The following basic guidelines demonstrate the capacity your space will require, based on standard 8-foot ceilings:

  • 7,500 BTUs = 150 square feet
  • 9,000 BTUs = 200 square feet
  • 10,000 BTUs = 300 square feet
  • 12,000 BTUs = 400 square feet
  • 13,000 BTUs = 450 square feet
  • 14,000 BTUs = 500 square feet

We can categorize portable air conditioners by room size:

Small Rooms: portable air conditioners with 7,000 – 10,000 BTUs work well in small bedrooms or offices up to 300 square feet.

Medium-Sized Spaces: portable air conditioners with 10,000 – 14,000 BTUs work well in cooling medium to large areas such as living rooms, sun rooms, or larger bedrooms or offices that are between 350 and 700 square feet.

Large/Commercial Applications: There are industrial-sized portable air conditioners that are suited for commercial and larger industrial applications, such as server rooms, manufacturing facilities, and special event spaces. Some of the larger retail portable air conditioners work well in machine and server rooms.

The hotter it is outside the more BTUs you will need to stay cool. So if you’re in the Nevada desert on a hot summer afternoon, you will require more power than the cooler evening hours or in your cabin on a lake in Maine. Other things to consider would be the amount of sun exposure of your room, glass doors or larger windows and the heat that is being generated in your room by other appliances. Therefore, consider both room size and your living conditions when choosing the size of your portable air conditioner.

How will using a Portable Air Conditioner Affect My Electric Bill?

Like any air conditioner, it will consume energy. How much it consumes simply depends on the model, as portable air conditioners come in many sizes that are suitable for different spaces. The model will list the BTU and energy efficiency ratings, which can be found online as you do your research. Using a portable air conditioner can save energy in comparison to a central unit. Keeping the door and windows closed keeps the cool air in the room, which is the most efficient way to operate your machine.

Some simple math can show you a sample cost factor. If your unit runs 24/7, meaning the compressor never turns off or you never reach your temperature – and a kilowatt hour in your area is 12 cents – this unit would cost you about $2.88 a day or about $85/month. But the chance is you will use your machine a few hours a day, or overnight. In that case your cost of ownership would be from $15-30/month. But the amount of energy your unit draws depends on the BTUs and energy efficiency rating, so do your homework.

Your electric utility bill will show your actual cost per kilowatt (kW) hour and you can do the math like this: average kW cost per hour (.12) x amount of hours (4) x one month (30) = $ 14.40.

How Do Portable Air Conditioners Work?

How Do Portable Air Conditioners WorkPortable air conditioners are ingeniously designed to allow their use with a very simple installation. The big takeaway is this; air conditioners need to suck in fresh air and propel the hot exhaust outdoors to prevent the hot air from coming back into your room. This is much simpler for window air conditioning units since the compressor, which brings in fresh air and pushes out hot air, is already outside, which is part of the unit.

Portable air conditioners overcome the complications of installation by using a tube to accommodate air flow in and out. The tube is connected to the unit and placed through a window or other convenient opening. If you move the unit, the tube will come with it. Dual-hosed portable air conditioners work by acquiring air from the outside with one hose and using that air to cool the unit. The hot exhaust air is removed with the second hose, making these units more efficient, but usually larger than single hose models.

Operating a Portable Air Conditioner

Operating a Portable Air ConditionerOperating portable air conditioners is quite simple. You can roll it into the room where it will be used, plug it into the electricity with the supplied electric cable, and connect the hose(s) from the unit to the outdoors.

Some maintenance may be required to empty of the water reservoir as all air conditioners draw water from the humid air and condensation can build up. This is not an issue with window and central air conditioners that are installed mostly outdoors, unless the water drainage hose gets blocked or some other malfunction occurs.

Since portable air conditioners are kept indoors, the unit either self-evaporates, provides a fitting for a drainage hose, or collects the condensation in a water tank that must be emptied regularly. Most models will shut off if the tank becomes full in order to prevent leakage.

Venting Portable Air Conditioners

You must install your portable air conditioner properly in order exhaust the hot air, or it won’t cool properly. The warm air is exhausted using a window venting kit, although normal-sized windows are not always available. There are kits available to install and vent portable air conditioner using dryer vents, for casement windows, ceiling ventilation, through the wall and even doors.

Installing Your Portable Air Conditioner with a Window Kit

Most portable air conditioners are very simple to install using the provided window venting kit. Standard window kits include a window bracket, one or two vent hoses and adapters. Vent hoses range from 4 to 5 feet, so you the unit should be close to a window.

Step 1: Attach the hose connectors or adapters and insert the hose or hoses into the unit.

Step 2: Place the adjustable window kit in your window and open it until it fills the entire width. You may need to cut the window bracket to fit your window properly and some models provide screws to secure the window kit. Finally close the window to fasten the kit in place. No need to remove screens you may have on the outside of the window.

Step 3: Next you will connect the vent hose to the window kit. Once your model is properly installed and vented, plug it in, power it on and start cooling your room.

Step 4: Most models allow you to program your fan, temperature and self-timing settings. It’s that easy!

Replacing Portable Air Conditioner Window Kits

Replacing Portable Air Conditioner Window KitsIt’s not uncommon to need a replacement window kit or a different kit to fit your specific window or door. Portable air conditioner accessories are widely available for purchase, although the best option is to find an alternative from the manufacturer or the model. In any case, the chances are good that you can find a replacement that will fit your needs. Some people go to hobbyist stores and make their own kits with canvas or other materials.

Most of the window brackets supplied with portable air conditioners are meant for horizontal installation at the bottom of a window. With some minor modifications they can be installed vertically to accommodate sliding windows and doors.

Sliding Windows and Doors

Sliding windows present the problem of length, so the bracket must be long enough to fit the larger opening. Some models provide window kits with double window brackets that work in sliding windows. A double bracket is a standard window bracket plus an additional bracket that lets you fill in the extra space. Once you set up the brackets, you can fill the opening with filler materials like canvas, wood or Plexiglas.

Wall Ventilation

Although it is a more substantial project, there are advantages to exhausting the hot air and running a drainage hose through a wall vent, directly to the outside. You can use a jigsaw or other device to cut the correct a hole in the wall and can seal the edges with silicone caulk. You may also call a technician to do this for you.

Connecting to Dryer Vents

Although dryer vents and portable air conditioner vents seems very similar, using dryer vents is not recommended. Most dryer vents have smaller diameters than the exhaust hoses for most portable air conditioners, so they would not fit well. Also, if the external opening of the dryer vent has a flap, which many do, the portable air conditioner’s hot air exhaust will likely not be strong enough to push it open.

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.

Single or Double Exhaust Hose?

Portable air conditioners use a single or double-hosed application for pulling in air to cool and to exhaust hot air. Here’s is how they work:

Single-Hose operation takes in air from the room, cools it and blasts the now cold air back into the room. Some of the air brought into the machine will actually cool the appliance before being blown out of the air conditioner’s exhaust hose. This creates some negative air pressure because it uses room air to cool down the compressor.

Dual-Hose operation takes in room air, cools it, and provides nice cold air back into your space, just as the single hose option. Because the unit generates a lot of heat, an intake hose draws air from outside to cool it down. Then, the hot air is expelled through a second exhaust hose. The dual-hose option, as a result, does not create negative pressure inside the room and may be more efficient as it doesn’t have to work as hard during the cooling process. The negative aspect of dual-hose operation is the use of warmer, unconditioned air to cool the compressor, which often results in slightly less operational efficiency.

5 Tips for Maintaining Your Portable Air Conditioner

 Tips for Maintaining Your Portable Air ConditionerLike any valued appliance, keeping your portable air conditioner in great shape will extend its life and help you save plenty of money with its more efficient operation. Take care of your unit properly and it will keep you cool and take care you of in return.

Keep it Clean, Inside and Out

The true measure of beauty is what we carry inside of us. The same can be said for portable air conditioners. This is not a joke. If you want your unit to work efficiently over time, you’ll need to keep it clean.

The most important parts to keep clean and beautiful are the condenser coils. Take a look at them from time to time and if their beauty begins to fade use a coil-cleaner. Alternatively, you can use an acidic solution made from water and either lemon juice or vinegar. Spray the mixture onto the coils and let it sit for a few minutes to take care of dust and debris.

When cleaning the house, remember your portable air conditioner. It likes to look good like the rest of us. Make sure it’s turned off and use a clean, damp cloth without cleaners or chemicals, to wipe the exterior. Make sure you clean and vacuum all the dust out of the vents that bring in airflow.

Filters and Exhaust Hoses Need to be Maintained

Air conditioner filters work best when they are clean. Keeping all filters free and clear of dust and dirt helps your unit achieve its optimum performance. Your filters will last longer and clean the air more efficiently when they are clean.

If you don’t clean your filters, dirt and dust gets drawn into the machine and settles on the evaporator coil. If you let it build, the coil will be so dirty it won’t be able transfer heat properly and may overheat. Some filters should be changed regularly, so check the instructions in your model user guide to find out if that applies to you.

Your exhaust hose wants to be as straight and short as possible in order minimize the amount of moisture getting inside, which will just end up in the unit. Water leakage most likely damages or shortens life of the appliance.

Even if you do keep your exhaust straight and short, it’s still a good idea to check it every once in a while to make sure there is no excess moisture gathering inside. Taking a few minutes to check this every month could potentially add years to the life of the device.

Positioning Your Unit

Just as the unit itself needs to be cleaned regularly, it should also be positioned in a relatively clean environment. If you place it in a very dusty or dirty corner, that grime will get into the machine. So either keep the surrounding area clean, or move it to a better location.

The same applies to humidity. If you place your unit in a particularly humid room, even if it is a self-evaporating unit, the chances are it will need to drain. So in humid rooms or environments, you will want to use a drainage hose that either leads to a bucket that you can empty or goes directly outside.

Storing Your Portable Air Conditioner

If your portable air conditioner isn’t a year round appliance, you will need to store it properly. Clean it and drain it of any water or moisture, inside and out. By running the unit on high speed fan setting for a few hours, the interior will get dry enough to store. Cover the unit to keep if free of dust and place it in a dry, cool place. Do not store your portable air conditioner in excessive heat or cold, so your attic or garage are not recommended.

Double Check Your Power Source

Your portable air conditioner needs at least 120VAC to power the compressor and get you cool. If your electric circuit doesn’t deliver the juice, you can easily short the fuse or your circuit. Surge protectors are always a good idea if you’re afraid of frying your unit.

How Does the Water Drain from Portable Air Conditioners?

Portable air conditioners eliminate warm air and moisture from the air and expel the hot exhaust outside through a window kit. But there is still a lot of moisture to deal with, which is called condensate water:

Auto/Self-Evaporative Models

There are advanced portable air conditioners pull the moisture out of your room along with the warm air and expel it in the exhaust hose. This requires you to never or occasionally empty the collected condensate water. These models are popular since they are generally hands-off.

Gravity Drain and Condensate Pump

A frequently used method of expelling the collected water is to attach a drainage hose, which some models include. There is a drain port that allows you to direct the water to a collection point or a condensation pump, which pumps the water out through the window.

Manual Removal

Standard, or simple portable air conditioners, have water buckets that must be emptied regularly. Some as often as hourly in very hot and humid conditions and others as little as once a month, depending on your humidity and amount of use.

All air conditioners need water to create cool air, and portable units make their own water by pulling the moisture out of the air. Since the units are in your home and not sitting out the window, it makes sense that you should keep your eye on water leakage or make sure that excess water has a place to drain.

If your unit is full of collected water, it will refuse to turn on. Most experienced consumers place a long clear tube into the drainage plug which is usually located near the bottom rear of the machine. You will want to experiment to see what works for you and the needs of your unit.

But keep in mind that even if your unit says it has an auto evaporation mode, in principal you are not supposed to dump water by hand. But many buyers in humid climes find that there is a build-up of water that needs to be dealt with. Draining it one way or the other will be necessary at some point.

Some Dos and Don’ts in Using Portable Air Conditioners

DON’T: Do Not Use an Extension cord for plugging into the electricity.

Air Conditioners are simply not designed to be used with extension cords. Every unit issues a caution on the box and in the user manual: DO NOT USE WITH AN EXTENSION CORD because it is a serious safety hazard.

Use of air conditioners with extension cords in very hot conditions are a frequently reported to be a cause of household fires by Fire Departments. When it’s very hot outside, air conditioners may not cool the inside of the room sufficiently, so the compressor will run continuously instead of turning off at regular intervals. As a result, the continuous cycling causes heat to build up and can eventually cause the cord to burn out and start a fire.

DO: How Do I place a hose in a window with a screen that can’t be removed?

Most vent mounts are designed for sliding windows and casements. With a little ingenuity, you can mount the diffuser against the screen and use an insulating panel, canvas or wood to cover the rest of the window. You will need to then secure the improvised cover so that it won’t fall out or blow away in a strong wind.

DON’T: Do Not Touch the Vent Hose

It is quite normal for the exhaust vent hoses to get hot, some get very hot depending on the size of the unit and the temperature outside. Vent hoses can get especially hot in  single hose air conditioners while they are in use. Not only will they be hot to the touch, but these hoses can radiate heat as well. If you are bothered by that or you have small kids around, you can install insulation sleeves or tape to keep the heat in.

DO: Change the Filters

Most units have removable air filter that can be cleaned with a vacuum cleaner or washed in warm water using a mild detergent. Most models recommend cleaning your filters at least every two weeks, but depending on the indoor air quality, you may want to increase the frequency of the cleanings. Dirty air filters restrict and reduce airflow which reduce efficiency.


Portable air conditioners are ideal solutions if this is what you need. In cases where you are simply prevented by code or other agreement from using window units and are not in a position to use central air, portables will do the job and will not feel like a compromise.

When you do have the choice between a window unit and a portable, you should take some time to consider your needs and balance that with price considerations to decide if a portable is a good fit for you. The best benefit of portable air conditioners is the ease with which you can install them and move them from room to room, or to a new home.

Large units can be wheeled into a room and set up in minutes by anyone, with a hose positioned from the unit to a venting kit in a nearby window. A large window until typically requires two people to place it in the window, and requires a bracing fixture to be installed on the outside wall to balance the heavy unit. On a second floor or attic, this can be a cumbersome and dangerous task.

Portable air conditioners bring state of the art cooling and heating technology exactly where you need it and to places that may not be accessible to any other solution. For people with allergies or asthma, portable air conditioners with their dehumidification and air freshening, may be the best and most energy efficient solution for a restful sleep.

Consider energy efficiency ratings and the method of evaporation before you purchase. Many models are eco-friendly and energy efficient, which brings your cost of ownership down. There are also many models that tout self-evaporation that don’t require you to collect and dump water on a regular basis.
