Upgrading Your Aircon: When to Service and When to Replace

Upgrading Your Aircon: When to Service and When to Replace

We can all agree that we are more productive when we are cool and comfortable, and in Singapore’s tropical climate, air conditioners are key players in helping us achieve this. But, just like any other household appliance, air conditioners have a finite lifespan and might need fixing or replacing from time to time. As such, how do we know when it’s time to replace our air conditioners or when it’s time to invest in a new one? Let’s find out.

Understanding the Lifespan of an Air Conditioner

Air conditioners aren’t built to last indefinitely. On average, a well-maintained unit can be expected to perform optimally for 15 to 20 years. However, there are several factors that influence the overall longevity of your aircon unit, such as the frequency of usage, the prevailing local climate, and, most importantly, regular maintenance habits like aircon servicing. Therefore, as your air conditioner ages, it is vital to pay attention to signs that indicate it might need servicing.

Signs Your Air Conditioner Needs Servicing

1. Insufficient Cooling

If your air conditioner isn’t cooling your space as efficiently as it used to, it’s a clear sign that something might be off. Possible culprits include low refrigerant levels, a dirty evaporator coil, which is responsible for absorbing heat from the indoor air, or a malfunctioning compressor, which is responsible for compressing the refrigerant and maintaining proper pressure.

2. Unusual Sounds or odours

Unusual sounds or unpleasant odours coming from your air conditioner could signal that something’s not right. Squealing, grinding, or banging noises might indicate problems with the fan or motor, while unpleasant smells could suggest the presence of mould or other contaminants in the system.

3. Poor Airflow

If your air conditioning isn’t blowing enough cool air, it could be because of various issues, such as clogged filters, blocked ducts, or a malfunctioning fan. Accumulation of debris in clogged filters hinders the free flow of air, while blocked ducts and a malfunctioning fan can further disrupt the seamless circulation of conditioned air.

4. Frequent Cycling

If your air conditioner consistently cycles on and off, a condition referred to as short cycling, it not only diminishes energy efficiency but may also indicate an underlying problem. This can happen for different reasons, like a t malfunctioning thermostat that inaccurately gauges temperature settings, insufficient refrigerant levels that impede the cooling process, or the installation of an oversized unit that cools the space too quickly, triggering premature cycling.

5. Leaking or Moisture Issues

Having water leaks near your air conditioner or excess moisture in the vicinity can pose serious risks, such as mould growth and structural damage. The source of these concerns is often traced back to issues like a clogged condensate drain, refrigerant leaks, or complications with the evaporator coil that helps cool the air.

When to Replace Your Air Conditioner

1. Age of the Unit

As mentioned earlier, the typical lifespan of an air conditioner is approximately 15 to 20 years. If yours is getting close to or has passed that timeframe, it could be smart to think about investing in a new, energy-efficient model. This could prove more cost-effective than continually repairing an older system.

2. Frequent and Costly Repairs

If you’re finding that you need to schedule repairs frequently and the repair costs are piling up, it might make more financial sense to invest in a new air conditioner. Modern units are not just more reliable but also designed with improved energy efficiency. Upgrading could save you money in the long run and introduce you to advanced features that align with current technology standards.

3. Increased Energy Bills

Ageing air conditioners typically become less energy-efficient, which can lead to higher utility bills. Choosing to upgrade to a more energy-efficient model can result in significant long-term savings, providing you with economic benefits while contributing to a more sustainable lifestyle.

4. Incompatibility with Modern Technology

Technology is advancing rapidly, and air conditioners are no exception. If your current unit isn’t compatible with smart thermostats and energy management systems, upgrading to a newer model can seamlessly integrate your cooling system into your home automation setup. This not only adds convenience but also enhances the overall efficiency of your living space.


Knowing when to service or replace your air conditioner is important for maintaining comfort and efficiency in your indoor space. Doing regular check-ups can make your aircon last longer, but if problems stick around, think about factors like how old it is, how much repairs cost, if it’s energy-efficient, and if it works well with modern tech when deciding if you should upgrade.
