Our MDV air conditioning system in Australia will use less energy if it is working efficiently, regardless of whether you are using warm air in the winter to heat your living room or blasting cold air in the summer to cool your home. 

Our efficiency tips discussed in this article will help you save money on your electricity bill and make the most of your air conditioning unit. 

An efficient air conditioner in Australia is not only better for your bank account, but it’s also more sustainable for the environment. 

Maintaining a steady temperature inside your home is one of the best things you can do to keep your air conditioner system working at its best. That way, it doesn’t need to work as hard. 


Choose the Correct Capacity


The first step to improving our energy efficiency is selecting the right air conditioning unit. It is important to select the right-sized unit for the space in which it will be cooling or heating. This will ensure that the unit is efficient and that costs are reduced. The size of air conditioners is measured in kW of capacity output. There are many variables that affect the calculation. Correctly sizing the unit is critical as it can cause a loss of efficiency. You can get the correct capacity size by having a certified technician come out and measure your space. 


Better Energy Star Rating


Once you know the correct size system for your needs, the next step is to compare star ratings or energy ratings on units with similar capacities. 

The Energy Rating Label displays the energy performance of specific appliances and equipment. It allows consumers to understand the cost of a particular model and its energy efficiency in comparison to similar models. 

This label gives customers enough information to help them determine which units are more energy-efficient than others. Based on an assumed average usage, it shows how much energy the appliance uses in kilowatts per year. It also lists star ratings. The appliance’s star rating is a measure of how energy-efficient it is and the lower its operating costs. 


Ideal Settings for Efficiency and Performance


The ideal fan speed for cooling mode is high speed. We recommend that you reduce this speed to low or medium speed later in the night. 

Select either the heating or cooling mode to make your air conditioner system work best. In residential applications, we don’t recommend the use of “auto mode” as it can cause your system to switch between cooling and heating at the same time. Therefore, select cooling if you wish to cool your home. Select heating if you wish to heat your home. 

The “dry mode” is used to dehumidify air-conditioned rooms. It will do this at predetermined times and for set periods, even if the temperature in the room has reached the set point. This allows the air conditioner to remove moisture from the air without cooling it. 


The fan mode will allow air circulation. This mode does not allow for cooling, heating, or dehumidification. IACS recommend this for night-time when it is not too hot or too cold. However, air movement is necessary. 


Change the Air Filters


It is important to inspect the filters in your HVAC system every so often. This will not only keep your air conditioner’s efficiency high but also lower your electricity bills. 

The frequency with which your air filters need to be changed depends on many factors, including the size of the household, the presence of pets and the indoor air quality. 

It is recommended that you change your air filters every 3-4 months. This should be done before extreme weather conditions, such as high temperatures or the peak of summer, hit the area. The air quality will improve if you change your filters more frequently. 


Ideal Room Set Temperature


Air conditioners perform best when they are in cooling mode. This means that the temperature should be between 22°C and 24°C with a medium fan speed setting. It is possible to adjust it at any time, but efficiency can be affected. 

The more efficiently your air conditioner runs, the closer it is to the outside temperature. The controller’s set point refers to the temperature the user has entered. 

IACS believes that cooling mode should be between 22°C and 24°C, with the outside temperature at 36°C or below. The unit’s efficiency may be affected if the temperature outside is higher than 36°C. 

The air conditioner will operate in a cooling mode by selecting between 22°C and 24°C. 


Close All Doors and Windows When Unit is On


This is another simple tip to improve your air conditioner’s efficiency that will save you a lot of money. 

If you close all the doors, the unit will only calculate the workload needed to cool the room. If you leave the doors open, the unit will work harder to cool the rest. 

Make sure you close all doors leading outside. Otherwise, this will cause your energy consumption to skyrocket, and you’ll lose all the cooling benefits. 


Ideal Number of Zones


If you don’t take care of your zoned ducted residential air conditioning system, you may be losing efficiency. The more zones you have, the greater the change in performance. 

Your air conditioner’s performance may be affected if it is trying to cool all rooms in your house, including the kitchen and living area, on a 36°C day. 

IACS recommends using a zoned ducted air conditioner for the day/night principle. It means that in the morning, you should only turn on the zones you are currently using. You can do this in the living room and kitchen. In the evening, switch off these areas and turn on the bedrooms. 


Ceiling Fans Can Help with Air Conditioning Flow


An air conditioner can cool a room by using a fan to circulate cool air. The air conditioner unit won’t have to work as hard to reach the far corners of the room it is located in. This allows it to cool down faster and for longer periods of time, saving money and giving you the opportunity to give it periodic breaks. 


Monitor Indoor Humidity


Humidity is a key factor in indoor temperature control. The ideal indoor humidity range is between 30% and 50%. 

Maintaining the perfect humidity level can be difficult. It depends on many factors, such as the season, clothing, and personal needs. If you are having difficulty maintaining the ideal climate in your home, check the humidity levels. 

When humidity is high, you can use the dry mode of your air conditioner. This mode will work more efficiently than the energy-intensive cool option. 

Smart thermostats or smart AC controllers can be used to monitor humidity. These devices can automate indoor humidity levels. 


Get a Professional Tune Up


Residential air-conditioning units are machines made up of moving parts, compressed gas, and other components. If the unit is left to deteriorate over the winter, it can cause problems that could affect the unit’s efficiency when it starts up in the summer. A professional can give the unit a tune-up.

Look Out for Debris


It’s possible to forget about your AC’s outside unit because it’s not visible. It’s a good idea to set reminders and ensure that you check for any debris around the outside of your AC unit. 

If dirt, leaves, and debris get into your air conditioner’s ducts or outside unit, it can block the air vents. This will cause your conditioner to not work as well as it should. Your outdoor compressor may be blocked, and this could cause a reduction in ventilation. To keep your air conditioner in peak condition, create a shaded and cool area for your outdoor unit. 

Air conditioners are lifesavers in the scorching heat of an Australian summer. You will feel extreme discomfort in your home and office if you don’t take care of it. You now know the best method! The best way to cool down in the summer heat is to turn on the air conditioner before the temperature reaches its peak. You can turn on the zones for rooms being used right now. Set the fan speed to high. If the air conditioner doesn’t meet your expectations, reach out to our team at IACS for advice and guidance on who to contact to clean and replace your filters. If the air conditioner doesn’t work properly, it might need to be serviced. Ask us for trusted service companies.
