What should you look out for?
Types of system – split-systems, reverse-cycle and more
There are different type of air conditioner systems ranging from split-system, multi-splits, ducted, wall/ window. They all have their own pros and cons. Price varies for each type as each have different advantages. For example, the Midea single split (the only one in the market!) is easy to maintain and clean. Ideal for those who wants a low maintenance air-condtioner.
Inverter or non-inverter? Inverter air-cons generally cost less to run but non-inverter is cheaper to buy.
Choosing the right capacity
Cooling and heating capacities (sizes) are rated in kilowatts (kW). A small room might require a 2.5kW model, while a large open-plan area might need 6kW or more. It’s important to accurately calculate the required cooling capacity of your new air conditioner to the room size.
Cooling appliances can account for a large portion of your energy usage. To save money when running your air conditioner, there are several things you should look at.
- Size: Having the correct size of air conditioner is an important first step
- Star ratings: a model with more stars will be more efficient and use less power than a model with fewer stars.
Features and functions
Different brands have different features. For example, Midea has a ‘Super Cool’ function to rapidly bring the room temperature down. Choose one that best suits your needs.
Other useful features that is generally found in most air-conditioners are:
The fan circulates air around the room. Look for a model with a wide airflow range and multiple fan speeds: from very high – to help the room cool down quickly, to very low – so there’s less noise and no unpleasant draught once you have the right temperature.
- Auto: Automatically chooses the mode required to keep the room at the chosen temperature.
- Fan only: Blows air without heating, cooling or drying, which is useful when all you want is a cooling breeze.
- Economy: Also called Eco mode, this reduces power consumption. Different brands implement this in different ways. It may simply reduce the cooling or heating output by adjusting the thermostat a degree or two, or it may use sensors to detect if no one is in the room and then reduce the cooling/heating.
Human presence sensor
This detects whether someone is actually in the room, so that the unit knows to keep working. When no one is detected, the unit might switch to an economy mode to reduce power consumption.
This function adjusts the temperature in steps, to a comfortable level for sleeping so the air conditioner doesn’t work as hard (and more quietly)
Other things to consider
Consider installation costs and requirements when you’re shopping for your air-conditioner.
- Location of the air-conditioner
Cool air is heavier than warm air. So, for optimum cooling, the air outlet should be installed as close to the ceiling as possible.
It’s generally better to install an air conditioner on a longer wall of a room, but your installer should recommend the best place for your individual situation.
If you value, having a peace of mind do look out the warranty coverage. It is important to understand the different warranty coverage. Some warranty provided covers only for certain aspect of an air-conditioner.
While some might provide wider coverage , such as Midea’s 6 years compressor warranty + 2 years part + 1 year service. Therefore it is important to look at the fine details and understand the coverage or limitations of your warranty.
