Air Conditioners are very common in Singapore.

Interestingly, CNA reports that the country has more air-conditioner installations per capita than anywhere in Southeast Asia.

This shows how important this appliance is for Singaporeans.

That said, if you are very few that do not have this yet or are considering buying a new one, let’s explore why it is a must-have, the crucial considerations when buying one, and some expert tips on extending its lifespan.

Why You Need an Aircon in Singapore

  • Tropical Climate

As mentioned above, the weather in Singapore tends to be hot and humid year-round. The temperature is usually between 25 to 31 degrees Celsius. In addition, the humidity level can rise to 83.9 per cent! This makes the heat all the more oppressive. That said, the ideal humidity should only be around 45 per cent. With this, aircon units are a necessity as it provides a much-needed respite from the scorching weather.

  • Improved Indoor Air Quality

Besides cooling, an aircon can help filter and circulate indoor air, thus, removing dust, pollen, or any allergens. Interestingly, studies show that having an aircon installed can have positive effects on health, especially for recovering patients. They note that air conditioning units help improve people’s vital signs, reduce cardiac arrest incidents, and accelerate people’s recovery

  • Enhanced Work and Living Environments

At work, an aircon can improve work performance by 25 per cent. Likewise, it also leads to less employee absenteeism as they are comfortable in their workplace. On the other hand, at home, an air-conditioned environment fosters focus, relaxation, and restful sleep. This contributes to a higher quality of life.

Things to Consider When Buying an Aircon in Singapore

Knowing the importance of having an aircon, let’s explore what you need to consider when you are planning to buy one.

  • Cooling Capacity

This size and cooling capacity of an aircon must be tailored to the space you want to cool. This is because an underpowered unit will struggle to cool your space while an overpowered may lead to unnecessary energy consumption.

As such, research a unit’s capacity to know whether that is good for your space or not. You can also ask for professional advice from various sellers or service providers to have a better understanding of what is best for your space.

  • Energy Efficiency

Look for energy-efficient models to minimize electricity consumption. In Singapore, air conditioners come with an energy label that indicates their efficiency. Opting for a unit with more ticks on the label could save you money in the long run.

  • Brand and Model

Choosing a reputable brand often means better quality, reliability, and after-sales service. As such, you must consider brands such as Daikin, Mitsubishi, Midea, LG, and Panasonic as they are known for their durability and performance.

  • Budget Considerations

Choose a unit that is best for your budget. That said, please research their durability and performance. This is because you may get a cheap unit now but it may end up costing more due to repairs and high energy consumption. On the other hand, you may choose a unit that is expensive upfront but can last for years.

  • Warranty

Ensure that the aircon you are planning to buy comes with a solid warranty. Likewise, check what it covers. Also, consider the brand’s reputation for after-sales service. Having these in place can make any problems with your unit easy to address.

Types of Air Conditioners Available in Singapore

To help you better decide on which air conditioning units to buy, here are the usual types of air conditioners found in Singapore.

  • Split Type Aircon

A split-type unit comprises of an outdoor unit and an indoor unit. The outdoor unit has the condenser and the compressor while the indoor unit has the evaporator, air handler, and air filters.

The split type allows for better temperature control and energy efficiency.

Popular Brands: Mitsubishi, Daikin, Panasonic

Suitable For: Individual rooms or small apartments

  • Multi-Split System

A multi-split system allows you to connect several indoor units to a single outdoor unit. This type of unit is known to be cost and energy efficient and its installation is highly flexible.

Popular Brands: Daikin, Panasonic, Samsung, LG, Fujitsu

Suitable For: Larger homes with multiple rooms

  • Window Aircon

This is a small type of aircon that is placed in a the frame of a window. Compared to the split-type, all parts and components are within a single box/casing. The cost of this type of aircon is usually lower than the split-type. However, it is difficult to relocate and it consumes more electricity.

Popular Brands: Sharp, Toshiba, Carrier 

Suitable For: Small rooms or spaces where installation of split-type is not possible

  • Portable Aircon

These units offer flexibility and can be moved from room to room. While not as efficient as other types, they can provide temporary cooling solutions.

Suitable For: Offices, commercial spaces, or homes looking for a seamless appearance

Special Note!

Apart from checking the type of the aircon you want to buy, also check if they are inverters. For context, inverters are air conditioners where the temperature is adjusted by controlling the speed of the compressor without turning the unit on and off.

Basically, the compressor runs at full speed when it needs to reach a certain temperature, then, it turns off after that. If the temperature rises, the compressor will run again to reach the desired temperature. The cycle continues as the aircon is on.

Inverters can be any of the types of aircon mentioned above. In addition, inverters consumer less power, thus, is easier on your electric bill.

How to Extend the Lifespan of Your Aircon

For context, various sources say an aircon can last for 15 to 20 years. Here’s how to get your unit to reach maximise its lifespan:

  • Regular Maintenance: Regular servicing, including cleaning or replacing filters and inspecting for potential issues, can significantly extend your aircon’s life. Do not wait for the telltale signs that it needs maintenance. Schedule regular maintenance sessions which include deep cleaning to extend its life.
  • Use the Right Settings: Using the correct temperature and mode settings can prevent overstraining the unit. A temperature setting around 24–25°C is typically sufficient for comfort without overburdening the system.
  • Avoid Constant Usage: Allowing your aircon to rest by turning it off when not needed can prolong its lifespan. Using fans in conjunction with the air conditioner or setting a timer can reduce the continuous strain on the unit.
  • Keep Outdoor Unit Clean: The outdoor component of the aircon also requires care. Ensure it is free from obstructions and debris to prevent overheating and maintain efficiency.
