Best Air Conditioner Buying Guide For Your Home | What To Consider Before Buying New & Used AC?

Best Air Conditioner Buying Guide: – Increasingly, air conditioning has ceased to be a luxury item and has become a basic appliance in our homes. Temperature changes and hot days even out of season have made air conditioning more than necessary, providing more quality of life in everyday life.

When buying one you need to choose carefully, as there are many features to be taken into account and obtain the best product.

Air conditioner (AC) is a machine made to stabilize the temperature and humidity of the air in a room. This tool is used to cool or heat, depending on needs. However, air conditioners are often referred to as air conditioners because they are more used to cool the room.

Although air conditioning is a product of modern technology, the concept of air conditioning has been known since the Middle Ages, namely in the days of Ancient Rome and Persia.

Willis Haviland Carrier was the first to invent a large-scale modern air conditioner that used electricity in 1902.

Major functions of AC

As the name implies, the air conditioner has a function to condition the air in a room to feel cool, comfortable, and healthy. There are three things that can be conditioned or regulated by using air conditioning, namely temperature, humidity, and air cleanliness.

Other than the regulations of these characters, there are also other functions and uses of AC. Such as:

  1. Adjust the Air Temperature

The main function of the air conditioner is to regulate the temperature in the room. You can set the desired temperature through the numbers printed on the remote control. In general, the lowest AC temperature is 18 degrees Celsius and the highest temperature is 30 degrees Celsius.

  1. Regulate Air Humidity

The temperature and humidity of the air are interrelated so that indirectly, the air conditioner also functions to regulate humidity. The temperature of the air conditioner should be set at an ideal temperature, which is 24-26 degrees Celsius because the air if too cold has high humidity, causing the skin to dry quickly.

  1. Clean the air

The AC machine is equipped with filters to filter out dust and dirt in the air so that it becomes clean and healthy. Therefore, the AC filter must be cleaned regularly to get rid of the filtered dirt so the air can be kept cool and clean.

  1. Overcoming Heatstroke

If you experience symptoms of a very hot body and feel faint when the body is exposed to hot temperatures for a long time it is one of the symptoms of heatstroke. In these conditions, AC can be a good solution to help lower your body temperature.

  1. Overcoming Sleep Disorders

AC can also be useful to help you improve sleep quality, especially for those who often experience disturbances during sleep. If you want to use the AC

when going to sleep make sure the AC temperature is not too low which will make the room temperature becomes very cold. Because if it happens it will disrupt your sleep hours and make you often wake up because the temperature is too cold.

  1. Avoid dehydration

Dehydration occurs due to excessive weather or temperature and the temperature causes your body to sweat which makes the fluid in the body decrease. Now by using this AC can reduce the risk of dehydration because the AC has a function to eliminate the heat that causes the body to sweat.

  1. Elements for Relaxation

The function of air conditioners as an air conditioner has a purpose to give you comfort and reduce stress in someone because of a problem they are facing.

To get more relaxation from the use of this air conditioner you can add it by playing classical music and lighting aromatherapy candles that will spread the aroma to all parts of the room from the air conditioner.

  1. Helps Reduce Asthma and Allergies

The air quality produced by this air conditioner has good uses for your health especially to reduce asthma and allergies. Because AC has the performance function to eliminate bacteria, pollution, and can inhibit the growth of mold and fungus that can cause you to experience asthma and allergies.

Advantages of having AC at the home, office or anywhere

Did you know that in addition to making the room temperature much more pleasant,  air conditioning can still bring several benefits to your health? In addition to cooling or heating the ambient air, the device has many other beneficial functions. Such as:

  1. Performs air purification

Modern, high-tech air conditioners – such as  HEPA and activated carbon filters – filter the air while purifying it, keeping the air clean for longer. The environment is free of pollution and other dirt that was previously dispersed in the air.

The result is a healthier environment, benefiting everyone, but especially people with respiratory problems such as rhinitis, sinusitis, bronchitis, and asthma.

  1. Has antiallergic action

Several models of air conditioning are able to combat the growth of fungi and other active allergens, preventing and reducing symptoms. Such as itching, sneezing, and irritations in the nose, eyes, and throat, among other allergic manifestations.

However, for this function to be effective, it is essential to keep the device clean. One way to understand when to clean it is to observe the presence of a  bad smell in the environment when turning on the appliance.

  1. Eliminates mold from the environment

Those who live in very humid regions with excessive rain, the presence of rivers and the sea, for example, tend to suffer from the effects of the humidity typical of these places.

If we previously showed health problems related to humidity, we now mention the damage caused by mold to the environment. Mold is capable of generating issues such as black and stained walls, tiles with black grouts, with slime or mold, clothes stored with the characteristic smell of mold, among others.

Air conditioning units with dehumidifying function remove excess moisture from the environment,  eliminating mold.

  1. Extends the life of electronic devices

This is another advantage of the dehumidifying function of air conditioning, which benefits families who live in regions with very high relative humidity, such as in coastal cities.

Excessive humidity damages the interior of the appliances by facilitating rust. In this case, the air conditioner extends the useful life of electronic devices by preventing the humid air from coming into contact with the internal parts and with all the equipment wiring.

  1. Increases the comfort of environments

The air conditioning generates a lot of comfort and stress relief from day to day, for allowing the maintenance of the desired temperature at any time of the day.

Even during the hours of intense sun or on the contrary, on very cold days, when everything that is desired is an air conditioner with the function of heating the environment.

To take advantage of this benefit, a simple but valuable tip is to direct the air vents so that the breeze, cool or heated, spreads better, filling the entire area.

In addition, close doors and windows so that the cooled or heated air does not leave the environment outside or to rooms where no one is.

  1. Offers multifunctionality

Instead of having a fan, you should invest in a single appliance that does all of this: it regulates the temperature, filters, and controls the humidity of the air, more or less. One of the biggest advantages of air conditioning is that it combines all of these functions.

  1. Prevents body dehydration

By keeping the air humidity constant, the air conditioner collaborates to prevent body dehydration. This benefit occurs because in environments with ideal humidity the body does not sweat much, preventing water from being lost through sweat.

  1. Prevents insects and dust from entering

In general, the heat forces us to open the windows so that the breeze enters the rooms, but with the air conditioning, it is the opposite. It makes us close them, and this represents a great advantage.

With windows and doors closed, we don’t have unwanted visitors, like insects. With the use of the air conditioning unit, flies and mosquitoes from dengue and zica are far from our home.

Your family will no longer be dependent on repellents and electronic rackets. In addition to insects, dust and other dirt from the street are also left outside – meaning a cleaner house with less risk of dust and dust mite allergies.

  1. Decreases external noise

In addition to insects and dust, keeping windows closed also reduces the entry of noise from outside. For those who live on very busy avenues or close to concert halls and nightclubs, this quality of air conditioning sounds like a promise of relief for headaches, to be able to rest more days, and to get rid of daily stress.

Drawbacks of AC

If you are impressed with the uses and benefits of the AC, then you must also know the drawbacks of AC. It also has some harmful effects on your health. Such as:

  1. Can make you Fat

Numerous studies confirm the allegation that a comfortable temperature is one of the 10 main causes of weight gain. Comfortable air temperature in the room often makes us lazy to move.

The lack of body activity negates the release of fat-burning energy. In the long run, fat deposits will accumulate in our bodies and lead to obesity. Therefore, those who are accustomed to living in air-conditioned rooms are advised to have regular exercise schedules to burn body fat.

  1. Sick Building Syndrome

The difference in air temperature between air-cooled rooms and outdoor spaces can affect endurance. Moving into a cold room in a state of sweat after doing activities in the sun can cause headaches, weakness, shortness of breath, even difficulty concentrating.

  1. Disease transmission

Almost all air-conditioned rooms lack ventilation. This condition makes the air circulation not smooth and only produces recycled air. When one of the inhabitants carries a virus, the virus will automatically be trapped in the room so that the potential for transmitting to other residents is quick.

  1. Skin aging

The air conditioning machine works to reduce air temperature by capturing water particles in the air to produce cold air. This condition indirectly decreases the humidity of the air which triggers the problem of dry skin.

If most of our time is spent in air-conditioned rooms make it a habit to use extra moisturizer for the skin. We must have a trick to maintain skin moisture in order to maintain elasticity.

  1. Costs

Although costs vary depending on the type of equipment and use, the consumption of electricity and energy is high by AC. Even if you have bought the cheap AC, you have to pay higher bills every month.

This means that only responsible use of air conditioning can make it a good option, otherwise, it will be just a bad purchase that at the end of the month will increase your energy bill.

  1. It is not suitable for those who have breathing problems

Experts do not advise installing air conditioning systems in homes with people who suffer from respiratory problems. As the variation caused by artificial air circulation can be extremely harmful to their health.

  1. Maintenance

Maintenance is inevitable in any medium / long term equipment and air conditioning systems, no matter how good they are, are not free of this. There are parts that wear out (as is natural) and the use itself will determine the useful life of the equipment.

Features of AC

If you are in the thought of purchasing AC, then it is a must that you know about all the features of AC. How do these features work? What are the functions of each feature of AC? Here are the functions and features of AC that you must know.

  1. Self-cleaning function

One of the most important functions inside the equipment is responsible for preventing dust and dirt from accumulating inside the equipment. But beware!

Despite its great importance for the proper functioning of the air conditioning, the self – cleaning function does not dispense with the need for periodic maintenance and cleaning, which must be carried out by a specialist technician in the area.

  1. Fan function

The fan function is one of the functions of the most useful air conditioning equipment. It is very good for air conditioning environments on days with mild temperatures, ventilating environments, and renewing the air, as it adjusts the speed and intensity of the fan air conditioning. This function does not change the temperature, it only ventilates.

  1. Sleep function

This function is great for a comfortable night’s sleep: you can set a more pleasant temperature while you sleep or even turn off the air conditioner at the right time. It is one of the most practical air conditioning functions, and you can configure it using your device’s remote control.

  1. Timer function

With this function, you can program the number of hours you want your air conditioner to work. In addition, you can schedule times when you want your equipment to turn on or off. You can set the clock using the remote control.

  1. Turbo function

Also known as JetCool, this air conditioning function can also be adjusted using your equipment’s remote control. It is very effective when you want to cool an environment quickly and efficiently!

  1. Swing function

By means of the position of the fins (which help in directing the air outlet) present in the appliance. The Swing function of the air conditioner helps to leave the air conditioning temperatures and to distribute the air outlet more homogeneously to the environment.

Types of air condition

There are several types of air conditioners available in the market with a variety of prices and features. therefore it is essential to know the types of air condition so we know what we are paying for. Some of the common models that are available in the market are as follows:

  1. Portable air conditioner

This type of air conditioning is ideal for small environments. The great advantage of this model is its portability, as its name indicates. That is, you can easily transport it from one room to another in the house, which creates much more comfort and convenience for the user.

  1. Split air conditioning

Without a doubt, the Split model is the darling when it comes to air conditioning. This is because this type of device combines practicality and efficiency in the right doses, being recommended both for small environments and for larger places.

Everything will depend on the capacity of the model. The most common type of Split is the so-called Split Hi-Wall, which is installed on the wall. In addition to it, there are other models of Split that may be more suitable according to your need.

  1. Inverter air conditioning

Inverter air conditioners are great alternatives because they combine economy, durability, and practicality. As it does not turn on and off, like conventional equipment, it generates less wear on the engine and, consequently, less noise and less energy expenditure.

This is because inversion technology means that the air conditioning compressor never needs to be turned off, just by reversing the controlling frequency of the air compression speed. Thus, the voltage peaks typical of reclosing do not occur.

  1. Window air conditioner

This air conditioning model is more compact, with condenser and evaporator units attached to the same cabinet. For this reason, it is indicated only for small environments, being installed in spaces (holes) already existing in the walls of houses and apartments.

  1. Ducted air conditioning

Also called central air conditioning, the ducted model combines the installation of ducts in the ceiling and a small lowering in the plaster or ceiling for the installation of the appliance.

The condenser, in turn, is installed in an open location with air circulation, as well as the Split. Ducted models are generally recommended for large locations (doctor’s offices, shopping malls, cinemas, etc.), with extensive thermal load and with the need for air conditioning in several environments at the same time.

However, this type of air conditioning has also become a viable alternative for high-end apartments.

Avoid mistakes when choosing the air conditioning voltage. If you are doing this without the assistance of a technician, check if the voltage of the location where you are (110 or 220 volts) is compatible with the device you will buy. Thus preventing the equipment from burning out in a short time.

  1. Prefer to buy new air conditioning models

Be careful when buying appliances that have already been used and have no validity. When buying your air conditioner always prefer new models that come with a guarantee. And preferably with the ideal power to cool the environment in which the equipment will be installed.

  1. Opt for well-known brands

When buying your air conditioner, always look for and search for brands that have good positioning and recognition in the market, this will bring you more confidence and security.

You should buy models that are ecological and high technology, manufactured by the best brands in the market. Such as Springer, Carrier, Midea, Elgin, Consul, Philco, Fujitsu, Panasonic, Daikin, LG, and Samsung. It’s better to choose an AC brand that is already well-known and recommended by many people.

Don’t be afraid of high prices, because there is a price, there must be quality. But still, try to read usage reviews from other people. So, you can determine the brand of your choice without regret.

  1. Get the right power for your home

This is a very important issue that needs to be decided before purchasing the air conditioner. It doesn’t matter if the equipment is split or window, the amount of BTUs will determine the cooling power of the chosen model.

After all, nothing worse than buying new equipment, and it simply does not allow the environment to be installed. You can do some calculations and you need to take some factors into account to get the ideal power for your home.

To get a sense, a 9000 BTU air conditioner is recommended for a 15 square meter room. A 12000 BTU model is perfect for a 20 square meter environment.

  1. Attention to the installation of the equipment

The window air conditioner is the easiest to install. Just have a standard hole made in the wall (if the property doesn’t already have it) and the consumer can install it himself.

Split air conditioners are different. It is necessary to hire specialized professionals to carry out the installation correctly. So the tip is to include this amount in the purchase budget for this type of equipment.

  1. Do a lot of research on device types before purchase

The consumer finds a wide variety of air conditioning models from different brands on the market. There are devices with a hot/cold cycle (which can also be used as a heater in winter), equipment with remote control, automatic shutdown functions, etc.

For this reason, it is important to do good research before buying. That way you know more about features, powers, among other details that will help you to choose the best device for your home.

Split Hi-Wall air conditioners, for example, are the best-selling category. Perfect for residential use, the equipment offers intelligent features, as well as being quieter when compared to window air conditioners.

  1. Select the appropriate type of air conditioner

There are several types of air conditioners that you can choose according to your needs. The types of air conditioners are split AC, or AC standing floor. However, for home use, you can use split air conditioners and cassettes, depending on the room. Even so, split  AC is currently the most commonly used.

  1. Pay attention to important features on the AC

Next, make sure the features in the  AC  that you buy are suitable for your needs. It’s a good idea to read about the important features of air conditioners.

Are there the latest features, such as low power consumption, automatic mode, and others. Use this feature as well as possible, because it’s useless if you have bought an air conditioner with the latest technology, but you don’t use it.

  1. Number of people in the room

The number of people in the room will also affect the level of cold and the performance of the air conditioner you use. A room with too many people and an insufficient amount of energy will certainly make the AC temperature not too cold, and make it work harder.

Therefore, the energy election on the AC also depends on the number of people who will be in the room.

  1. The importance of electricity saving features

Buying an air conditioner with technology that allows electric power to be taken less, aka power saving, is very important to be a consideration. Nowadays, many manufacturers have provided their products with electricity saving features. So, it is not difficult to find it.

  1. Simple Design

We know that the current design of air conditioners is very diverse, just try past one of the nearest electronics stores. And pay attention to a variety of cooling products that are displayed in one corner of the store.

Of the many designs, choose a simple design. So, when you clean the AC filter there is no need to bother removing the components.

  1. Determine a budget

Of course, you need to make sure what your budget is when you want to buy something, in this case, AC. In the market, there must be a variety of product lines from the low end, mid to high end.

All you have to do is adjust how much expenditure you’ve determined to choose the air conditioner, and choose the best.

  1. Laying AC

After that, you also need to pay attention to which room you will install the AC. If you want to put it in a room, the suitable type is the split type and the temperature is 23 -24 Celsius.

For the living room and family room, you can use the air conditioner with cassette type and set the temperature around 23-26 Celsius.

  1. Choose PK as needed

PK is the cooling capacity or the ability of the air conditioner to cool the room. If the selected PK AC capacity is too small then your room will be less cold and the AC will work harder. And vice versa, if the PK is too big then your room will be too cold and will certainly be wasteful of electricity.

  1. Consider Additional Features

Nowadays AC has a lot of sophisticated features such as wifi connectivity. In addition to these advanced features, you should prioritize basic features that will definitely be very useful. Such as:

  • Air purifier feature
  • Anti Virus
  • Anti-bacterial
  • Deodorizing
  1. Noise

It is important that you also inquire about the noise of the device during operation. General statements such as quiet operation should also be confirmed by a decibel value. Because if you consider that many air conditioning units reach more than 50 decibels, modern units can be significantly lower.

  1. Latest technology

It is important that the air conditioning system matches the desired cooling requirement. Because if an air conditioning system continuously works at the limit of its performance, because it is in a room that is too large or too hot.

It will not only break down faster but will also consume a lot more energy. It is therefore important to ensure that the cooling and dehumidifying performance is set exactly.

The latest air conditioning systems even have a flexible compressor whose speed of rotation adapts to the cooling requirements. This automatic rotational speed control is responsible for ensuring that the temperatures remain constant and reduces energy consumption by up to 30 percent compared to on / off devices.

On top of that, these devices are also a lot quieter, as they only reach 25 decibels at the lowest rotation level.

  1. What should my air conditioner do?

This may sound like a silly question, but it really isn’t. If you buy an air conditioner, of course, it is because you need to cool the interior spaces of your home. But this is only the basic function.

Especially for fixed systems, there is the possibility to choose between other options in addition to the cooling capacity.

For example, heat pump models allow you to heat rooms in the cold period, in particular, they can be useful in the autumn. Fitted air conditioner heat pump means it is useful to meet this need.

Another interesting feature can be the integrated dehumidifier or ionizer, which allows you to purify the air of the environment in which you live.

Tips to buy used AC

Air Conditioner or AC is a tool that is able to change the surrounding air to be cold that can be adjusted by using the remote control.

The price of AC is very diverse and sometimes does not fit in the bag, therefore many people who prefer a used air conditioner as an alternative to getting low prices. So here are some tips for you when you want to buy the used AC.

  1. Conduct physical structure checks on used AC

Checking the physical conditioning of the AC is mandatory because the physical feature is a prominent part and people will be more focused on the physical of an item than inside structure.

If there is a physical defect, try asking why it is defective. And if there are minor scratches it is still in a reasonable stage, but if there are cracks, it should be asked to the seller about this.

  1. Check used AC equipment

In addition to checking the physical part, do not forget to check the used AC equipment that will be purchased. Whether there are certain compulsory features or not and whether they are operating perfectly or not.

Do not forget to ask about the warranty of the air conditioner, if it still exists then ask the seller to see the warranty of the item still valid or not.

  1. Check the performance of the AC

After checking the AC equipment parts, don’t forget to check whether the air conditioner is running or not. Do a few tries before a deal is made with the seller so that the item can be ascertained to be suitable for use.

  1. When the air conditioner is on

The other vital step is to check how when the air conditioner is turned on if something is abnormal or all goes well. You can try it by pressing the on-off button on the power to find out if it is still functioning properly.

  1. Check used air conditioner sound

If the air conditioner is running, it does not mean that it’s good, you also have to make sure that the AC sound is smooth and does not make strange or unpleasant sounds.

If there is a sound like that then it must be suspected and immediately ask the seller about the condition and the cause of the unusual sound.

  1. Outdoor unit

You surely know that air conditioners have outdoor units that are usually installed outdoors. Try to check whether the compressor is original or not, don’t forget to see whether the condenser has a leak or not.

Also, make sure the transfer of electricity from the indoor to outdoor units can be connected without problems.

  1. Check the Installation Connection

Part of the cable installation connections is very important because it will certainly greatly affect the performance of the AC. So don’t forget to check the cables when buying a used air conditioner.

Check if there are damaged cables such as peeling or sticking together. This cable problem can cause a short circuit and also damage to the AC.

  1. Remote AC

In addition to checking the AC, you also need to check the AC remote that you are buying. Check whether the remote is functioning properly or not. You can test this AC remote by pressing buttons on the remote such as raising or lowering the temperature on the AC.

  1. Price

Not infrequently the seller gives a very low price to attract potential buyers. If you do not really understand the problem of air conditioning, it is better to invite friends who understand to assist in shopping.

Low prices are not necessarily of cheap quality because it depends on how smart you are in choosing good items. However, don’t be easily influenced by price and make decisions based on careful observation and smart choices.

The price we can pay for used air conditioning equipment is always going to be much less than what the same new equipment costs.

It should be something like half a little less than half the real value of the equipment so that our purchase is not a risk. Since if we are going to buy used equipment we should not pay a price close to what a new equipment cost.

Unlike used equipment, new equipment brings a much greater guarantee apart from the guarantee that the equipment is new without any use.

  1. If it’s a deal, ask the seller for warranty

This is done so that the seller does not provide goods that are not suitable for use. So that if there are problems or defects seen, then you can complain to the seller. Do not forget after buying a used air conditioner try to check the AC service available to ensure that the AC is still good or not.


If you have a budget and your pocket is full, it is always better to buy the new AC. But if you have a low budget, then you can opt to buy the used AC provided the condition of the air conditioner is good and operating.

Buying the used Air Condition can also be beneficial when you get the air condition of the best operational state at the lower price. So you do have to do a lot of research and search for the best quality used product.

Either within your community or in online sources, however, you do need to test its operation and functioning preferably by the mechanics if possible.
