What is an Air Conditioner?
Summer is great, though when the sun is boiling, the fun is not just as good. This is where air conditioners come in very helpful. The market has got a vast array of conditioning units to choose from - split air conditioner systems, window units, portable conditioners and many more. It’s easy to get lost. The good news is, there won’t be any trouble after you read this review. We’ve selected the most present-day air conditioners of different types to tell you about their advantages so that you can choose the one, most suited for your special needs.
If you’ve already set your heart on any specific unit but haven’t found it in this review, we’d like to offer you more detailed reviews on portable air conditioners, window air conditioners and split system conditioners.
What Features to Compare
There are two types of household air conditioners: monoblock and split air conditioners. Monoblock air conditioners consist of a single block. Moreover, all their parts are located inside their construction. Note that monoblock air conditioners include window and portable air conditioner units. Such devices are easily mountable but rather noisy. On the contrary, split air conditioners consist of indoor and outdoor blocks. The indoor block is usually mounted on the wall not far from the window while the outdoor unit is mounted outside. In general, such devices are usually purchased for home and office use due to their moderate price and quiet operation.
The performance of an air conditioner depends on its capability to maintain a comfortable microclimate and cooling power. Cooling power is measured in BTUs/h (British thermal unit). To be more exact, BTU is the amount of thermal energy necessary to raise the temperature of 1 pound of pure liquid water by 1° F. Besides, consider an airflow rate of the device before purchasing. This index is measured in CFMs (cubic feet per minute). The higher this index is, the faster your room gets cool. Moreover, airflow rate has also significant impact on air dehumidification. Dehumidification is measured in a number of pints of excessive moisture removed from the air. We also recommend considering the noise level (it is measured in dB) an air conditioner produces during operation. Note that a low noise level is great for your relaxation and good mood. Finally, consider the area of your apartment or office when choosing an air conditioner.
All modern conditioners work in several modes. The prior purpose of any air conditioner is to cool the air. There are also air conditioning systems designed not only to cool but also heat the air and maintain favourable microclimate in your dwelling. The air conditioners with the heating capabilities are usually more expensive. The ventilation mode is important to circulate the air so that it doesn’t concentrate under the ceiling but evenly distributes around the room. Another mode frequently provided by air conditioner manufacturers is dehumidification. Those consumers who live in highly humid regions will surely get use out of it by effectively removing extra moisture from the air. When switched to dehumidification, the air conditioner still cools the air, but the temperature in the room doesn’t drop lower than by 1 degree Celsius. Not mandatory, but quite often air conditioners work in night mode too. When the night mode is on, the air conditioner slows down the speed of the fan and raises up the temperature. This way the unit comfortably switches to quieter operation, favourable for relaxation and sleep. In 2-7 hours it automatically shuts off. You can always rely on the automatic mode as well and never busy your mind with presettings. The conditioner is capable of maintaining the right temperature in your environment on its own.
The remote control can make the operation of the device very convenient. Due to Auto Restart function, the device will resume its operation after power cutoff. Besides, a programmable timer can switch the device on or off according to your schedule. Air filtration is also very important for creating a comfortable microclimate in your apartment. It is advised to purchase an air conditioner with removable and washable filters for its comfortable maintenance. It is great if your air conditioner has adjustable blades for airflow direction.
The Best Option for Home Use
Electronics Inc. is a South Korean electronics company that is widely known across the globe. We would like to present to you its LSA5NP5A split system for a good reason. It boasts the best quality/price ratio ever!
This split system has a sleek design with a small monitor that displays all basic information like actual settings and programmes. There's only one button at the bottom of the unit, Auto Restart, for resuming the settings after power cuts. On the right side of the unit, you'll notice the sensor for receiving signals from a remote control. Note that the remote has glowing buttons allowing you to operate the conditioner in the dark.
As for performance, this product is great for living rooms, bedrooms, large offices, etc. The cooling capacity of this model is 18000 BTU per hour, meaning the AC can effectively cool an area up to 50 m². The fan of the indoor unit is extremely powerful; the maximum air flow reaches up to incredible 565 CFM.
This AC features three operating modes: cooling, dehumidification, and air ventilation. When cooling, the appliance can operate in:
- Auto mode. Depending on the ambient temperature inside the room, the air conditioner automatically adjusts the cooling temperature and fan speed.
- Energy saving mode. 22 °C temperature is preset as the optimum one. If the temperature drops, the air conditioner just stops working and vice versa.
- Himalaya Cool. The technology provides instant and effective cooling of your room. Just press a button to activate smart airflow and fast vertical air swing.
- Sleep mode. Set this mode before going to bed, and the air conditioner will work at super low speed, automatically adjusting the temperature so that you could sleep restfully.
If you want to remove excess moisture from the air, especially during the monsoon season, you can simply press the "M`SOON" button and the air conditioner will start dehumidifying your room. In this mode, the device maintains the optimum humidity level and saves around 36 percents of energy. As for ventilation function, the air conditioner will use the fans of the indoor unit only.
Quiet and Functional
This very model has as many as three different filters - an antibacterial filter, a dust filter, a dual-protection filter. The LG LSA5NP5A cleans the air not only from dust and bacteria but also from mould and bacteria. Due to 3M micro protection filter technology, the conditioner traps even the most microscopic substances from entering the room to provide you with fresh and pure air.
Also, we would like to tell a few words about a smooth and nearly silent operation of both outdoor and indoor units. The noise level of evaporator makes only 36 dB which can be comparable to a whisper or stream. Thus, this quiet conditioner won't disturb you and people around you.
The energy efficiency rating of the LG air conditioner is 5 stars; it consumes up to 1.46 kW / h. Overall, it's one of the best models for cooling standard-sized rooms. The LG LSA5NP5A is compact, but its performance is huge!

It can work throughout the whole day consuming just 1.9 kW / h at the highest settings. In turbo mode, the noise level won't exceed 47 dB.
The condenser is manufactured from durable copper, thus it's pretty easy and cheap to maintain. This type of condenser is also very powerful and its cooling speed is amazing.
For Rooms and Offices
Daikin company was founded in 1924, and nowadays it's one of the biggest manufacturers of air conditioning systems in the world. In this review, we're going to tell you about the budget option, the FTQ35QRV16 split system. This air conditioner can cool spaces up to 30 m².
The design of the indoor unit is minimalist - there are no flashy decorations on its classic white body, you can only notice a small display on the right side. The kit includes indoor and outdoor units as well as instructions and a remote control. There are no tubes in the package, so you might need to buy them additionally.
The cooling power of the conditioner reaches 12,000 BTU / h, while its airflow rate is 342 CFM. The system has a copper condenser which is very durable and easy to use.
The model can neither heat nor dehumidify the air, therefore, it's an optimal choice for a warm and dry climate. The FTQ35QRV16 Split AC is a real catch for small offices.
If you don't need all those extra frills, you're at the right place. The FTQ35QRV16 is an air conditioner that does its main job only, but does it perfectly! The conditioner can cool at 3 different fan speeds, allowing you to choose the intensity you need.
If you want to cool down your room before going to bed, you can set "Sleep Mode". The air conditioner will gradually raise the temperature inside, saving energy and preventing you from overcooling. Also, the conditioner features the timer which can turn on and off the appliance at a pre-assigned time. For example, you can set a timer so that the air conditioner starts working two hours before your arrival. This way, you will be able to unwind after a long work day in the comfort of your pre-chilled apartment!
A Real Steal
This conditioner features only dust filter, meaning it won't be able to clean the air from bacteria and fungus... until you want it! You can always buy a filter with a silver mesh additionally to maximise air purification from all sorts of harmful bacteria.
Filter Cleaning by Yourself
Unfortunately, it doesn't take long for AC filters to get dusty and grimy. Dirty filters can hurt the energy efficiency, not to mention they are an ideal place for allergens and bacteria to collect and grow. So, it's vitally important to maintain them properly.
Voltas enterprise was founded in 1954 in the city of Mumbai, India. The company has been manufacturing high-quality air conditioning products for more than six decades. The company was a recipient of the National Energy Conservation Award 2013, and it was ranked 39th among the most reliable brands in India in 2014.
Taking into account Voltas experience, we couldn't skip its best-selling 185JY air conditioner. Due to the aluminium condenser, the split system is affordable and durable. The indoor unit has a traditional rectangular shape, however, a small red strip on the front panel adds a modern touch to its look and sets it apart from standard models. Above the company logo, you'll notice a LED display that shows the ambient temperature and operating mode. By the way, the display is designed in such a way that it will be visible only when the air conditioner works. If the device is turned off, you might think that it has no display at all.
The performance of the model is 18000 BTU / h, which is quite enough for large rooms, offices and other spaces up to 50 m². The air flow can reach 850 CFM to let cool air circulate like crazy in your room.
Three Modes for a Comfortable Environment in a Room
The model can perform cooling, dehumidifying, and air ventilation. When it's operating in cooling mode, you can select the desired fan speed to maintain a comfortable temperature in a room. However, if you need to chill your place as quickly as possible, you can switch on the turbo mode, and the fan will run at the maximum speed.
If the air in your room becomes overly humid, this might lead to the appearance of mould or fungus. However, with this appliance, you can prevent this! Just switch to a dehumidification mode from time to time. The air conditioner will alter between cooling and ventilation, thus maintaining the optimum level of humidity in your room. In case you feel comfortable lying on your couch and don't need to reduce the temperature of the air in the room, you can use the ventilation mode. Operating as a fan, the conditioner will help you relax and blow away the stresses of a day.
Efficient and Cost-effective Cooling
This split system is highly praised for its high performance and low energy consumption. Case in point, it has the best 5-star energy rating, meaning it uses less energy than most other conditioner and dramatically saves on operating expenses. To be more specific, the device consumes only 1.4 kW / h. It's one of the most energy efficient devices in its class but not one of the most silent. The max noise level can reach 45 dB comparable to refrigerator humming.
Thanks to the huge cooling capacity and minimum power consumption, the Voltas conditioner is ideal for both home and office use. Instantly lowering the temperature of the room, it will allow you to create a comfortable environment for work or relaxation.

Owing to Auto Climate Technology, this conditioner can recognise humidity and ambient temperature and then automatically correct the fan speed and temperature to provide you with a chilly, comfortable environment.
The appliance has a special "Powerful Mode" which increases the fan speed to the maximum level for fast and effective cooling of your room. Before going to bed, we recommend you to switch the device to "Kamin Function". It's a kind of sleep mode which raises the temperature by 1°C every hour for up to 4 hours, providing you with a sound sleep. Also, operating in this mode, the conditioner doesn't consume a lot of energy. Another useful feature is "Auto Humid Control" - it doesn't matter whether you live in dry or humid climate, the Hitachi AC will regulate the humidity level for creating a comfortable environment in your room.
The air conditioner has two filters, the Koukin filter can purify the air from the bacteria and the stainless steel plated filter is designed to stop dust and dirt. We would like to stress that the condenser of the split system is produced from copper that needs low maintenance.
This 5-star AC is an excellent power-saving solution that will help you significantly cut down your costs on electricity bills. The appliance is very quiet, it produces only 38 dB which could be compared to a conversation between two people.
As for the extras, we would like to stress that the Hitachi AC has On/Off timer that will help you pre-set the time and temperature so that your room will be chilled by the time you're back home. The remote control features Digilock function that allows you to set a digital password and lock the AC, thereby preventing any misuse by your guests or curious children. Moreover, Digilock can also shut off the display to prolong a battery life.
One Touch Silent Cooling
Although the air conditioner works almost silently, you can make it even less noisy by pressing a special button, "One Touch Silent Cooling". So, if you're looking for a model to install in your bedroom or nursery, you'll hardly find a better option!
Q: What capacity do I need to properly cool my home? How can I determine the size of the air conditioning system needed?
A: Actually, there might be many factors in your house that affect the size of an air conditioner and the amount of BTUs required, such as the height of ceilings and the type of insulation. The BTU calculator can help you choose the right model for your home.
Q: Can I install a compressor on my attic or it needs to be installed outside?
A: The compressor must be installed outside only, since there should be air cyclic around the unit. You can always get special brackets to install it outside the house as high as you need.
Q: Is an air conditioner good for heating too?
A: Yes, most conditioners can heat air as well, but they work in an unusual way. In heating mode, a reversing valve shifts the direction of coolant flow so that the hot coils get cold and the cold coils get hot.
Q: Can I connect more than one inside unit (evaporator) to a single outside unit (condenser)?
A: It depends on the specific model. Some manufacturer offer 2, 3, 4 and even 5-zone multi-split systems.
Q: Will I need any mounting brackets and other installation pieces?
A: No. Almost all sets already include everything for easy mounting. The only additional product you might need is a line hide. It's optional but it really makes an air conditioning system look neater.
Q: How should I take care of my outside air conditioning unit?
A: You should regularly clean leaves and debris out of your compressor. By keeping it clean, you’ll maximise its efficiency. Also, examine your whole air conditioning system once a year. This will help you catch problems while they’re small and manageable.
