How to choose your silent mobile air conditioner

If you buy a quiet mobile air conditioner that is not designed to do the job you need, you may be sorely disappointed. You need to find a product that will work in the space you have, at a cost you can manage, while meeting all of your major needs. To find the quiet mobile air conditioner that checks all the boxes, make sure you consider the following factors when searching.

#1 - Noise level

Contrary to what many people think, even mobile air conditioners make noise. It doesn't matter if it's a packaged air conditioner or splitYou will experience some noise from any mobile air conditioner you purchase. For most, this noise will be minimal and described primarily as "background noise" that you probably won't even notice. However, it is still an important factor to consider when purchasing a mobile air conditioner.

If it's important for you to find a mobile air conditioner that doesn't add too much noise to your home when it's on, you can find one designed to be quieter than usual. If manufacturers have made efforts to make a mobile air conditioner quieter, you can bet they'll mention it in their marketing materials. But ultimately, one of your best sources for knowing what to expect from an air conditioner's noise level is to read customer reviews.

#2 - The size of the room

Formany buyers, the size of the air conditioner won't matter as much as the size of the space it's intended to cool. Most quiet mobile air conditioners don't cool an entire house or apartment; they're more useful for cooling specific rooms, like a bedroom or living room. What you want to look for then is air conditioning coverage.

Manufacturers use the British Thermal Unit or BTU to measure the capacity of their air conditioners. Generally speaking, the higher the BTU number, the larger the room an air conditioner will keep cool. Many manufacturers also specify the size of the room in which an air conditioner will be most effective.

#3 - Energy consumption

Depending onhow you're going to use your mobile air conditioner, you may find that the amount of energy you use increases (unless you use it to reduce consumption on your central air conditioning system). Fortunately, Energy Star has a handy directory of the mobile air conditioners they've evaluated, which even allows you to compare the energy efficiency performance of some models.

If saving on energy costs is important to you, you should also favor models with a programmable thermostat that will automatically turn off when your room reaches the temperature you set. And be sure to keep your unit clean and well-maintained , because any air conditioner that has to do more work because of poor maintenance will end up using more energy.

#4 - Ease of installation

Ingeneral, model air conditioners, including quiet ones, shouldn't be too much of a problem to install, or they wouldn't be able to claim the "mobile" label very effectively. The main thing you'll need to worry about is hooking up the window kit and the outdoor unit. Your quiet mobile air conditioner should come with clear step-by-step instructions on how to do this.

Anyone with basic DIY experience around the house should expect the process to be relatively quick and simple. If you don't have much DIY experience, it may be worth calling a friend to help you, but you can get an idea of how difficult the installation will be in advance from customer reviews.

#5 - The mode of release of the condensation

Thetype of condensate in your quiet mobile air conditioner is directly related to ease of use. Drip air conditioners deposit all condensate into an internal tank that must be emptied regularly. Partial drip air conditioners release most of the condensate through the drain pipe, but may still deposit water in a drip pan. You will still need to check the pan and empty it from time to time, but at lower frequencies.

The third and easiest option is to opt for drip-free mobile air conditioners. These release all the condensate into the air, so you never have to worry about emptying anything. Obviously, this is the most popular type of mobile air conditioner among homeowners.

The silent mobile air conditioner, a very practical solution

With a portable air conditioner, you won't have to worry about air conditioning regulations or city permits. And most importantly, you won't have to go through the hassle of condominium rules. Indeed, the facades of buildings in co-ownership are part of the common parts, it is thus necessary to pass by a General Assembly (GA) of the co-owners to obtain the authorization to install an air-conditioning which can deteriorate the external aspect.

It is a practical and simple solution, you buy it, you use it and that's it. And since such a device is quite compact, it will not clutter your window either and you will still be able to fully enjoy the view or the natural light in good weather.

Beware, split air conditioners are not as mobile as you think

Mobile" split air conditioners are not as mobile as you might think. Indeed, unlike mobile air conditioners monoblocs, they require a certain amount of installation work. They must be embedded in a ceiling or be fixed to a wall. They almost always come with wall brackets, screws and plugs. Think about this carefully when you buy so you won't be disappointed later.

The different types of silent mobile air conditioners

To enjoy a quiet air conditioning solution, you can choose between a split and a monobloc model.

Mobile air conditioner silent monobloc

The mobile air conditioner is made up of a single element. Equipped with wheels, it can be easily moved from one room to another. But note that it is a fairly heavy device. The packaged air conditioner may have one or two exhaust pipes. When it has two, that is, it has an additional air intake. The first one is used to evacuate the hot air. It is obvious that a model with two pipes is more efficient. To get the most out of the Silent option, find a unit with a soundproofing system.

Mobile silent split air conditioner

Contrary to the single-pack silent air conditioner, this one has 2 units, one of which is outside. This one contains the condenser and the compressor. The unit inside is extremely quiet. This is normal since the mechanism that makes all the noise is installed outside the house. Apart from that, users choose this unit for its compactness. It is easy to find a suitable place for it. The best models offer other options besides air cooling. Thus, you can have a device that also serves as an air dehumidifier.

Silent mobile air conditioner or window air conditioner?

Quiet mobile air conditioner

One of the most attractive features of a portable air conditioner is that it is extremely easy to install. You will receive a window kit through which you place a small exhaust. This is how the exhausted heat from the air in your room can be removed. Because of the mobility of the unit, you can move it from room to room depending on where you are and the area that needs your attention. Unlike a window unit that is installed and tends to stay in one place, you can move your portable unit from your bedroom upstairs to your office downstairs if the need arises.

Window air conditioner

A window air conditioner, on the other hand, doesn't have such flexible installation options. But it does have the advantage of being able to be placed entirely outside your living space, which is attractive to some people who like the idea of reducing clutter. Plus, a window air conditioner uses energy more efficiently than a portable unit. This means you get even more cooling power per BTU.

Verdict

So, if portability is important to you, a quiet mobile air conditioner will be more suitable. But if space and energy efficiency are more important to you, look to window air conditioners.

Even with a packaged model, you'll need a window

A quiet mobile air conditioner can't work without an exhaust pipe that must be vented to the outside as it extracts the warm air you want to release from the room. You can choose to vent through a window (the most common way), a wall, a ceiling or even a door in theory. But in any case, you'll need an opening to let the warm air out.

What are the main advantages of a silent mobile air conditioner?

Easy to install

The silent mobile air conditioner is very popular because of its ease of installation. It does not require a duct or opening in the room where it will be installed. This eliminates the need to make any changes to your home and you won't have to call in a professional. The appliance can be started at the touch of a button after filling the water tank.

Easy to move

By its name, the silent mobile air conditioner is very easy to move. Since there is no plugging in or wiring to connect, you can place it in any room of the house. You can also take it with you on your travels as it is generally small in size. You can also install a second air conditioner if the cooling capacity of a single unit is not sufficient.

Compact and powerful

All silent mobile air conditioners are designed to make your life easier. It is light, robust and has the right power to cool a room of up to 30 m. You can also optimise the cooling capacity by choosing a unit with a tank that matches the size of the area to be cooled.

Economical and environmentally friendly

The silent mobile air conditioner is also very appreciated for its ecological and economical side. Indeed, it is a low-polluting device because of its very autonomous character. It only needs a water tank and a proper energy source to operate. Not only is this type of air conditioner not energy consuming, but it is an ideal alternative for those who cannot afford to buy a fixed air conditioner.

Low noise

A quiet mobile air conditioner, as the name suggests, has extremely low noise pollution, unlike other models that sometimes cause sleep disturbances. This allows you to sleep better at night and enjoy a good night's rest. The noise level decreases as the heat increases.

Tips

Strategic installation.

Be careful where you install your mobile air conditioner. Especially try to avoid sunny and humid locations.

Ventilation.

No matter what type of mobile air conditioner you use, ventilation will always be one of the most important factors in ensuring optimal operation and long life of the unit. Use the appropriate ventilation kit for your window.

Clean the filter regularly.

It's

a given that your air conditioner's filter should be cleaned, if not changed, on a regular basis. This is not only important to keep the unit running smoothly and optimize cooling, but also to maintain your indoor air quality.

Store it properly when not in use.

Combine with a rotary fan.

Use

a small rotating fan near the unit. This will help circulate air throughout the room.

FAQ

What is the best silent mobile air conditioner?

The best quiet mobile air conditioner depends on your needs and budget. Read our buying guide to find out which products are the best at the moment.

What is a silent mobile air conditioner?

A mobile air conditioner is a self-contained portable system ideal for cooling individual rooms. They usually sit on the floor and come with an installation kit for quick setup. Most models also have wheels so you can move them around to different rooms, making them a great alternative to window units.

What is the power requirement for a mobile air conditioner?

Most mobile air conditioners operate on 115/120 volts, which is the standard household voltage. Almost all have a grounded plug. Keep in mind that units 14,000 BTU and larger may require special wiring and plugs.

Do all portable air conditioners need to be vented?

The short answer is yes. As with any air conditioning system, all portable air conditioners must be ventilated in some way. Portable air conditioners draw in warm air, cool it and expel the cooled air from the front of the unit and the remaining warm air and moisture from the back of the unit. It is this warm air and moisture that must be removed from the room you are currently cooling. The easiest and most popular way to vent your portable air conditioning unit is through a nearby window, which is why every portable air conditioner we offer on our site includes an easy to use window closure kit.

What happens to the moisture that is extracted from the air?

Since mobile air conditioners extract moisture as well as heat from the air, one might wonder where the water goes. Many units have self-evaporation technology. This innovative technology internally processes and evaporates the collected moisture, then releases it out the back of the unit. In very humid climates, water can accumulate in a tank inside the unit. In this case, you can either manually empty the tank when it is full or use the built-in gravity drain. That said, with recent advances in portable air conditioner technology, the need to drain is becoming less and less.
