Everyone wants to choose the one that will create the perfect microclimate in your home or office while saving money. But choosing the appropriate model yourself can be problematic. Specifications and instructions have little to say to ordinary users. Professionals can quickly answer your basic questions:
• What power size are essential?
• How much does the adjustment charges?
• How much will be electricity charges?
• How often do you required to order preventative maintenance?
• How loud is the conditioner?
ABC AIR specialists are happy to support you discover the proper sample for your house or office of any proportions and configuration. In the tutorial, we help customers deal with air conditioning models. We also describe common causes and conditions that influence the alternative of the air conditioner type.
How to choose the best Air Conditioner
For most residentiary buildings, the proper edition would be a reverse cycle split system. This air conditioner may be established in any houses, apartments, and offices, regardless of their layout.
Moreover, buyers could retain on the acquisition of preheating facilities for the colder months of the year.
What Air conditioner do I need
Split system air conditioner
Such a type comprise two parts conjoined by manifold with a refrigerant (particular gas):
- Potted part;
- External one.
Such systems are fitting for making a cozy microclimate in placement with no more than 55 m2. The expenses of such air conditioners are ordinarily $ 500- $ 6000 (relying upon the brand’s pricing policy).

This scheme acts almost the idem as a regular one, but owners may connect not one, but several internal parts to one outside pulley. Commonly, there are no more than eight. The variation is adequate for premises where it is not feasible to assemble ducted air conditioning. Users could adjust diverse settings in every part of the house.
People shouldn’t buy and place several external blocks because they spoil the architectural ensemble, one pulley is sufficient. The multiple system charges are comparable to the expense of assembling several regular split systems.
Ducted air conditioners
They have an inconspicuous focal pulley, ordinarily inclined out of sight on the housetop or under the level. Conduits put together theocentric sheave with digs through the walls and floor and transmitters in each room. This option is ideal for large homes with complex layouts. Such an air conditioner allows you to maintain different temperatures in different rooms if necessary.
At the same time, it is much cheaper to lay the system at the construction stage. Otherwise, you will have to make adjustments to the interior and buy additional details.
The approximate price range for medium-sized houses is $4000-15000. For industrial buildings, this amount may increase further.

Window air conditioners
They can be placed in window leaves if the design of the window allows. Also, some homeowners hang such blocks directly on the wall on the balcony or next to the window. This is a good way to cool a small apartment up to 45 m2. Such air conditioners are usually cheap, but not energy efficient at all.
You will save money at the time of purchase, but then you can be disappointed in the power or having received a large electricity bill. If we are talking about the city center, then such blocks can slightly spoil the appearance of the house facades.
One air conditioning for heating and cooling
The reverse cycle function is very convenient if you live in a temperate climate with hot summers and cold winters. Why do you litter the whole house with additional heating equipment, if you can combine two in one? The system is built on the fact that you can switch the cycle when you like with just one button. During cooling, the air conditioner draws out the warm air of their room. And with the reverse process, the engine pumps warm air from the street into the apartment.
Many brands of HVAC equipment use reverse technology in their designs. This helps not only expand the target audience but also increase customer satisfaction. Our company only works with trusted manufacturers who have an excellent reputation in the Australian market. Among them are:
- Kelvinator (Electrolux);
- Mitsubishi electric;
In addition to the lack of excess equipment in the house and saving on its purchase, the use of reversible air conditioners has another plus. Typically, heaters heat the room slowly. And the blades of the fan built into the air conditioner accelerate warm air around the room faster. Also, properly installed air conditioners are absolutely fireproof, unlike classic heaters.
For residents of areas with warm winters or owners of houses with central heating, air conditioning that works only for cooling is suitable. Such models have the same functions, like Wi-Fi or remote control, as well as motion sensors. Such equipment will effectively cool the house in the summer, while it will cost you less than equipment with a built-in reverse cycle.
How to calculate the air conditioner size?
We offer you rough power calculations based on the size of the room. We are based on the technical parameters of air conditioners specified by the manufacturers and on personal experience.
|Up to 19 m2||2.1-2.6kW|
|79 and more||6.1-9.5kW|
Now you can roughly guess which power conditioner is right for you. But do not rush to make a choice yourself. It is better to entrust the calculations to professionals to avoid the following problems:
- Models that are too powerful for room size can often perform short cycles to reach the target temperature. This can lead to the room becoming too cold or hot and excessive drainage of air, which affects the skin severely. Moreover, electricity consumption, electricity bills will increase. And the system itself will begin to wear out much faster.
- Models with insufficient power can operate more often at maximum power, which leads to a decrease in air humidity and excessive wear of all parts of the system.
For more information about room sizes calculation in our recent guide.
Professional recommendation: air conditioners that are ideally or powerfully selected with a maximum power of maximum 0.5 kW serve their owners the best and longest.
If a specialist considers that a 6 kW model is needed for a room, buy an air conditioner with a rated cooling capacity from 6 kW to 6.5 kW.
Online calculators on the websites of companies involved in the air conditioners installation give customers only a preliminary idea of the necessary equipment power. Before ordering a specific system, it is necessary to call the wizard on the object for more accurate calculations. You can enter the climate and room area data in the calculator, but it still does not take all the nuances. It is necessary to make corrections depending on whether the room is insulated or not, which side the windows face, and so on.
ABC AIR employees take into account the following factors in their calculations:
- Shading and curtains on the windows.
- Insulation of the floor, ceiling, and walls.
- Local climate.
- Restrictions due to local administration requirements.
- Frequency of use of the room.
- The number of people who are regularly in the room.
This is not all the data that we take into account. Masters take into account all the client’s wishes and the smallest house or office details. You may not even suppose that such insignificant things influence anything.
The maintaining a new air conditioner cost?
Operating costs for a medium-sized air conditioner range from $ 400 to $ 550 per year. This amount includes payment of electricity bills and regular preventive maintenance of the system by the company’s employees that installed the air conditioner.
The maintaining an air conditioner cost is highly dependent on the model and power. But based on our many years experience, we can demonstrate the following figures.
|Up to 3.5 kW||$240-490|
|More than 6.2 kW||$440-585|
We took into account the electricity cost is 30 cents / kWh. If the prices in your area are different, then the maintaining cost will vary.
How to determine the future noise level from equipment?
Most modern air conditioners are very quiet indoors and outdoors, but before you buy, it is worth checking the noise level to see if it causes you discomfort. Most modern split systems fit from 15 dB to 55 dB in the room and from 40 dB to 70 dB outside. We got these data with the minimum engine speed settings. Therefore, at maximum speed, there will be more noise.
To understand roughly what these numbers mean, look at these examples:
- A noise level of 55 dBA is obtained in a normal conversation between two people.
- A home vacuum cleaner generates noise at around 75-85dBA.
Pay attention to the rest mode, which allows the air conditioner to operate almost silently. This indicator is one of the most important, along with power. A noisy indoor unit will prevent you from working well or relaxing. Noisy outdoor units can interfere with neighbors and be banned by the local administration. There were times that the sounds of old outdoor air conditioners interfered with their owners, as they came through an open window.
What is affected by blower speed?
A fan circulates cooled or heated air around a room. The wider the blades and the higher the speed range, the better the device accelerates the cooled air. If it is possible to change the angle of the blades’ inclination, it is easy to direct the airflow only to a particular area of the room. The higher the fan speed, the faster and more evenly, the room cools. The lower the speed, the quieter the device works.
You can also turn on only the fan, without cooling or heating. This function helps to get a light breeze without coolness if the room is at a comfortable temperature. Some air conditioner models provide separate functions for draining or humidifying the air. The mixing of the air masses in the room also occurs using a fan without involving refrigerant.
Automatic presence detection
The sensor detects whether someone is in the room, so the device knows when to turn off or continue to work—some models automatically direct airflow towards people. When no movement is detected in the room for 20 minutes, it automatically enters the economy mode to reduce power consumption or turn off.
Air conditioning control via Wi-Fi
In this case, the user can turn the air conditioner on and off using the mobile application. You do not have to be at home for this. You can turn on the equipment when leaving work so that at your arrival in the apartment, it would be fresh and pleasant to be.
What are air filters and self-cleaning used for?
Air filtration allows you to fight against mold, bacteria, odors, and dust from the street. Such filters are handy for people with allergies, as the air becomes cleaner. Also, some air conditioners work additionally on the principle of exhaust ventilation. Such models will be the perfect choice for the kitchen to remove odors when cooking.
The filtration system is often supplemented with a self-cleaning function that allows you to keep the inside of the device dry and reduce dust accumulation and mold growth.
There are special filtration schemes that even trap smoke and superfine particles from the street. They must be installed additionally, or instead of typical filters. But in this case, the air in your house will not only be fresh but still really clean and safe even for asthmatics and allergy sufferers.
in one’s sleep, the human body cools a little, as all metabolic processes slow down. This means that you do not need the same intensive air cooling as during the day. Moreover, the street is more relaxed at night. Putting the air conditioner into sleep mode, you will get minimal cooling and maintaining a uniform temperature, the quietest sound possible, and saving energy.
Here you can talk about energy saving in general. Have you heard about ultra-modern models that have an energy efficiency class of seven stars? This technique can reduce your bill payment costs by 50%. These are huge amounts per year, even for an ordinary cottage. If we are talking about an office multistory building, the savings can be thousands of dollars.
Despite the fact that such devices are more expensive, they pay off in just six to eight months, and then they begin to bring benefits. Such a technique works in the same standard conditions as less energy-efficient appliances. There is no difference in installation either.
Which type is better?
For rooms with high ceilings, it is better to choose wall-mounted air conditioners and place them directly under the ceiling. Cassette indoor units that are mounted in the ceiling are adequately cooled, but may not be used in all rooms. Floor models are suitable for rooms of a simple configuration without partitions. Some models can be mounted anywhere in the room.
Automatic ice removal in winter
The anti-icing coating allows you to avoid freezing of the coils of the outdoor heat exchanger, as if this happens, the air conditioner will stop working.
How to install the air conditioner?
Professionals can only install complicated and expensive equipment with a license. Not only your comfort but also fire safety depends on the master. ABC AIR has been operating in the Australian market for more than ten years, and the average specialist experience is 15 years.
A qualified specialist must have a license to work with electric networks. Moreover, when it comes to installing a ducted air conditioner, installers must have a plumber license. Only with a combination of all these conditions you can get a guarantee of the correct calculations and high-quality installation.
Also, think about the period when you plan to purchase and install new equipment. If you do this in the arctic season, it is quite possible that you have to wait a long time in line or pay an additional amount for urgency. When the temperature in the street is still quite comfortable, you can choose without haste. And you call the master at a time convenient for you.
After you have purchased an air conditioner, do not forget to clean the filters and periodically service it. This will extend the period of trouble-free operation of the equipment by several years. Moreover, minor repairs made on time can prevent the wear of other parts and eliminate costly breakdowns.
Choose the type of air conditioner and its power based on professional calculations and recommendations. It helps avoid wearing the parts too quickly if the power is much more than necessary. A block with too little power cannot guarantee you high-quality.
Self-installation or maintenance is always a risk. Contact a professional for the correct installation. Only a professional installer can install the equipment correctly. Otherwise, there is a risk of increased electricity consumption and even a short circuit.
