What to Examine Before Buying a Desk Air Conditioner

Not all types of desktop coolers will be effective in every space, and finding the right desktop portable air conditioner will depend on your personal environment. As a result, there are multiple factors you may need to consider when choosing between a fan, a cooler, and a conditioner, including;

Budget: Obviously, when we are buying anything, one of the first factors we have to consider is our budgets. With most things, the more you pay, the better-quality product you will receive — with more high-tech cooling devices often being at the more expensive end of the market. However, there are plenty of budget-friendly options available, such as the Lasko 4916 mini tower fan.

Size and weight: It is important to consider your space when you are making any such purchase. If you are looking to place your desktop cooler in a permanent spot, you may even need to take measurements. The size and weight also impact a unit's portability. If you wish to move your cooling device frequently, choose a smaller or lighter option.

Noise: Ultimately, no cooling appliance can be silent, but some manufacturers offer quieter models. If you are sensitive to noise, check out a cooler or conditioner that offers low decibel levels. Examples of these include the Dyson bladeless fan, Evapolar’s EvaLIGHT, and the Midea air conditioning unit. These models will still emit low white noise, but research has suggested that this can be beneficial to our sleep patterns and even has the potential to boost productivity.

Energy efficiency: Air cooling and conditioning units can be relatively energy-intensive. As a result, it is important to choose one that suits your needs best. Depending on where you live, appliances may be granted an energy rating, with A++ being the best-performing units and G the worst. Comparing energy efficiency is also a great way to predict operating costs. For example, whilst an air conditioner may offer the best level of cooling, they can be expensive to run.

Room size: The dimensions of the room where you would like to place the air conditioner play a significant role in determining the size of the air cooler you need. For instance, if you have a small room that does not require extensive cooling, you should choose a mini air conditioner. It will fit the compact requirement and cool the room efficiently and cost-effectively. On the other hand, if you have a substantial room, a big fan is the smart choice that can serve your purpose with a sufficient cooling capacity.

Safety: When checking out potential desk air conditioners for your residential space, safety remains the first and foremost factor to be considered. Since water is a good conductor of electricity, make sure it doesn't come in contact with the latter. So, it is recommended to check the air cooler for leakage that may lead to a mishap. A good conditioner should also be safe for children so they can operate it safely to enjoy a cool breeze.

Placement: Efficient cooling also depends on the placement of the device. Firstly, do not place heavy air conditioners in higher places, since there are chances for it to fall and get damaged. Also, you should make sure that there are no water leakages, as they prevent the cooler from functioning properly and make a mess.


Mechanism: To put it plainly, you can segregate desk air conditioners in terms of their mechanisms – blade air conditioners and bladeless air conditioners. As the names themselves suggest, the former has blades, while the latter does not have blades (they have an electric motor that allows them to create and expel air).

Features: Various models from different manufacturers offer a range of features. For example, the Evapolar is a 3-in-1 device with cooling, humidifying, and purifying capabilities, whereas something like the Frigidaire window air conditioner may provide heating for when it gets cold. Others feature ionization, which is reported to be effective at trapping allergens. You could also consider whether you are likely to need a remote control and a timer, with the latter being useful if you prioritize energy conservation.

Of course, there is nothing critical if you miss one or two factors when choosing the best mini portable air conditioner. You can order the model you like and test it for two-three days. Most of the sellers allow the return if the device stays undamaged. However, the procedure can take some time, so invest some time and effort in choosing your best air conditioner.

What Types of Desktop Air Coolers Are Available?

How to choose the best desktop air cooler?

Basically, there are three main types of portable devices to cool air near your desk:

  1. Fans: From the smallest handheld options to the best desk fan imbued with the latest technology, this category includes a wide range of units with varying cooling capabilities and prices. Fans are possibly the most basic and the oldest of cooling options. They cannot reduce the temperature; instead, they must move the air around the room. In doing so, they produce an airflow, which then helps to evaporate sweat from the skin quicker to keep you cool.
  2. Evaporative Air Coolers: Compared to a fan, an evaporative air cooler also known as swamp coolers is often quieter. They are also relatively energy-efficient, particularly when you compare them to an air conditioner, with operating costs at around a tenth in comparison. Unlike ACs, there is no installation, and they are often portable, with some models being able to reduce the surrounding temperature up to 7-10 degrees C. Evaporative cooling is effective in dry climates, but they may not always be suitable for areas with high humidity.
  3. Air Conditioners: A portable air conditioner works by extracting hot air from the space in a form of heat exchange. They use a cooling chemical liquid that allows for compression, condensation, and then a release of the heat energy. The best portable air conditioners often feature a control so you can set up the perfect temperature. However, they can be expensive and often require permanent installation, which may not be possible for some.

What Are the Differences Between the Three?

  • Mechanisms: The key difference between air coolers, conditioners, and fans is the basic mechanism for each unit, as they all work in different ways. Fans are powered by a motor that spins the blades around to produce airflow. An evaporative air cooler works by sucking air through the filter pads located inside the machine. A small portable air conditioner uses a chemical agent that cools and conditions the air.
  • Cooling power: The power of a desktop AC unit is important, as this indicates the volume of air the device can cool. Refrigeration capacities for coolers and conditioners are often outlined by their BTUs, or British Thermal Units. This figure indicates a unit’s capabilities in that the higher the BTU, the larger the volume of air the device can cool. This can also reveal the price of running the unit.

    Fans usually offer a lower cooling power, as they cannot change the temperature. On the other hand, air conditioners are the most powerful, but they can be expensive to operate. Probably you do not need a great cooling because the air move is enough for your room.
  • Climate considerations: You can also take the average climate of your geographical location into consideration. For example, an air cooler adds water to the air, so it is not well-suited to humid conditions. Someone who lives in an area subject to frequent or seasonal weather changes may not wish to invest in a window air conditioner, with a fan suiting them just fine.

Why Your Desktop Air Conditioner Does Not Help

On a hot summer day, no one would want an air conditioner that doesn't provide adequate cooling. All you need is a reliable gadget that cools the room space pretty quickly with less consumption of electricity. However, if your portable desktop air conditioner is not able to operate fitly, then there might be some technical and non-technical faults you need to look into.

Gadget Malfunction: Malfunctioning of an internal component is one of the most common internal issues that lead to a fall in the performance of a mini air conditioner. External damage or internal short-circuits lead to the malfunctioning of the air compressor, which is the primary component of an air cooler. The air compressor is responsible for the circulation of air. Basically, if the compressor stops working, you should get the air conditioner checked and fixed immediately to avoid further complications.

The gadget is dirty: The majority of desk air conditioners contain air filters, which entrap the tiny dirt particles present in the air so that the air that comes out is pure and healthy. One of the main reasons for the malfunctioning of a device is the deposition of dirt in the air filter, which prohibits the circulation of air. Also, if the tabletop air conditioner is not brand new, it may be possible that dirt has made a place for itself over time inside the interiors of the machine, which causes internal blockage. Thus, air circulation is minimized, or worst-case scenario, the device stops working completely. To avoid this, it's recommended to clean the filters regularly.

Open windows: Desktop air conditioners work extremely well when the windows are completely closed or even if they are slightly open. If your air cooling appliance shows signs of premature faults in its operation, you should check whether the device is under extra stress. For instance, if you leave your windows open, the hot and humid air filled with dust particles can put too much pressure on the compressor and air filters. So it is pointless to use evaporative coolers for cooling if the windows are wide open.

Water is off: Air coolers use evaporation in order to convert water into cold air and circulate it throughout the room via bladed or bladeless fans. Many times, when the water in the air cooler's tank gets empty, the cooling stops because there is no water left that can be converted to cool air. Therefore, before starting an air cooler, make sure the tank is filled with fresh water so your residential space gets cooled swiftly without any wastage of electricity. Do not use the hot water for air coolers: it will not work as it should work.

Wrong type of gadget: While choosing a desktop air conditioner, you should make sure you opt for the right one by considering the factors mentioned at the beginning of the article. For example, if you have a small room, you should not waste your money on a large-sized fan, as it will not provide the best value for your money. Similarly, a small air-cooling appliance will not do any good in a large room. The features of the desktop air coolers also play a vital role in determining whether the gadget is suitable for you and your needs, such as the mechanism, fan speed options, design, etc.

As you see, most of these issues can be easily fixed. Just check your gadget from time to time to make sure it works properly, clean it regularly, and it will serve you for many years.
