Despite its features, this unit may have some downsides, and they are.


These units can be noisy and large

Due to the amount of power they consume.

Ducted Air Conditioners

This system provides the needed temperature through ducts spread all over the office or home, whether hot or cold. A ducted system is much more expensive than the others as the coverage is widespread for maximum range. However, suppose you want to provide your home or office with the proper air conditioning spanning the entire property. In that case, the ducted system air conditioner is right for you because it is highly efficient.

Buying an air conditioner

Air conditioners come in sizes and features, and one must widen their scope. The components may include a portable, inverter, non-inverter, and reverse-cycle air conditioner. Check out more information on these types.

Portable Air Conditioner

A portable air conditioner is handy for a small, owned or rented space. Because they require no installation, they are easy to move, less expensive, do not take up much space, and weigh less than most air conditioners. They can also be an indoor wall-mounted unit.

Inverter Air Conditioners

This cooling system utilizes a controlled compressor. The compressor acts as an accelerator and dictates how much is needed to fire up the air conditioner. Inverter models are in demand as most split air conditioners are inverted. Less energy is used with this system for efficient, full power, and less expensive units.


It draws less power as it is energy saving

Have controllable compressor units

Temperature can be changed as and when needed.

Environmentally friendly, saving up to 50% of energy

Non-Inverter Air Conditioners

This cooling system, unlike the inverter, works automatically to cool the room on its own or not at all. Without a controllable compressor, it works on impulse. The non-inverter can cause mass surges in energy consumption without human regulation as it is automated. Although they do not work as sufficiently as the inverter, they are less expensive than the inverter systems.


Inexpensive compared to inverter systems

Delivers a fixed amount of power in a room based on its temperature

Reverse-Cycle Air Conditioners

The reverse-cycle air conditioner is a cooling system that gives you the privilege of warming your house during those cold and warm seasons. This modern technology is like having a heating and warming device together with the press of a button. Aside from its heating and cooling abilities, it acts as an air dehumidifier and a filter. The heat pump in the reverse-cycle air conditioner performs the most crucial function to cool down the room temperature. Then reverse it and warm it back up using the refrigeration cycle.


It gives you a two for one deal; a heater and a refrigerator

Uses internal room temperature to provide the needed feel of cold or warm.

More room for your place as it is a two in one device instead of two devices

Capacity of your air conditioner

When buying an air conditioner, another feature to consider before landing on your is the capacity of the cooling system and the room size. Capacities are measured in kilowatts and room size in square meters. With the room’s size and the air conditioning’s capacity under control, other factors are essential to how best your selected AC can help.

Before deciding on the air conditioner, make to consider these factors:

Room sizes below 80 square meters can be recommended for window, portable, and split system air conditioners. Room sizes from 110 square meters and above are great for all other air conditioners.

You should also consider where you like the AC to be installed and the noise level it produces for noise level. For bedrooms, we recommend you to go in for a low noise air conditioner. Loud ACs can hinder your sleep, so it is best to opt for a split system air conditioner rather than a wall one.

Checking out the average city temperature or local climate can help you decide the type of air conditioning you prefer. In addition, knowing the moderate environment can help you determine how much capacity is needed to live in that region.

Another tip to consider is the number of people in a room when planning to buy an AC. The more people, the more the temperature rises, so. For example, you will need a 1.5 ton AC for the living room of a family of five.

Another way to determine the air conditioner’s capacity is by taking into account the BTU of the AC. British Thermal Units (BTU) is the standard measuring unit of an air conditioner. Accordingly, the higher the value of the BTU, the better the cooling of the air conditioner. Based on this standard, 1 ton is equivalent to 12000 BTU. For that reason, any air conditioner with more than 12000 BTU must have a higher cooling ability. It can help you understand some of the technicalities in performing AC.

Power Consumption of your air conditioner

We have just learned about BTU and the amount of energy it takes to power rooms of different sizes. It should tell you that all air conditioners are not the same as some run on a more significant energy capacity and efficiency than others. The factor that should concern you is how best the air conditioner can suck out hot air from your room and external surroundings and replace it with cool air.

When considering how much power an air conditioner uses, you should also consider the energy-saving abilities of the AC. These capabilities make the products more reliable. Sadly, the energy-efficient air conditioners are the expensive ones. However, it is far more rewarding in the long run to buy energy-efficient ACs than to buy any other. You can save more money in a year than purchasing any other type.

The plain air conditioner will consume more power than the energy-efficient one, which you have no option but to pay for.

To prevent such scenarios, manufacturers have designed a rating system to help you identify products that meet the Energy Efficiency Ratio (EER). The energy rating star is designed to show buyers how energy efficient an appliance is. This rating technique is a sticker with stars on it counting between one and five. One star means low energy saving, and a 5 star means a higher energy-saving appliance. The star rating logos are pretty conspicuous and can serve as a clue to guide you towards efficient and energy-saving air conditioning.

Features Of An Air Conditioner

Making your way to an air conditioner is one thing, and the entirely different thing is to stick to the appliance. The one thing that can motivate you to purchase is the features of specifications.

Air Filters

There are two types of filters in an air conditioner: washable and standard filters. The standard filter is the one that needs periodic changes to ensure proper airflow and filtration. The washable filter can be cleaned for continued use without replacing it with a new one. Air filters on air conditioners are added to remove germs, smoke, and odor.

Adjustable Louvers

Air conditioners have blade-like attachments to the outlet, which move to spread the air in whatever direction you may direct it.
