In Singapore, where air conditioning is practically essential for daily comfort, we rely heavily on our cooling systems to beat the heat and humidity. But while regular use is expected, improper use and poor habits can shorten the lifespan of your unit and lead to high repair costs or inefficiency.
Whether you own a residential system or a commercial unit, understanding what not to do to your air conditioner is just as important as knowing how to care for it. In this article, we highlight 7 common aircon mistakes to avoid in Singapore, so you can enjoy cool comfort without unnecessary breakdowns.
1. Skipping Regular Servicing
One of the biggest mistakes is not servicing your air conditioner regularly. Many homeowners in Singapore only call for aircon servicing when a problem arises, but by then, the damage may already be done.
Without routine cleaning and checks, dust, mould, and debris build up in the filters, coils, and drainpipes. This reduces efficiency, causes unpleasant odours, and may lead to water leaks or even compressor failure.
✅ What to do instead: Schedule professional servicing every 3 to 6 months, depending on usage. For heavy users or larger households, quarterly servicing is ideal.
2. Running the Aircon 24/7 Without Breaks
Singapore’s hot weather makes it tempting to run the aircon around the clock. However, constantly operating your unit without any rest puts unnecessary strain on its components. Over time, this can wear out the compressor, clog the filters faster, and increase the chance of breakdowns.
✅ What to do instead: Use a timer function to automatically turn off the unit after a few hours or when you’re asleep. You can also alternate with a fan when full cooling isn’t necessary.
3. Setting the Temperature Too Low
It’s a common misconception that setting the temperature to 16°C will cool the room faster. In reality, your aircon will cool at the same rate regardless of the target temperature. The only difference is that the compressor will work harder—and longer—to reach and maintain that extremely low temperature.
This not only increases your electricity bills but also puts a heavy burden on the system.
✅ What to do instead: Keep the thermostat at a comfortable and energy-efficient 24–25°C, which is ideal for Singapore’s climate and sufficient for most indoor environments.
4. Ignoring Strange Noises or Leaks
If you notice unusual sounds, water drips, or foul smells, these are signs your aircon needs immediate attention. Ignoring them can result in bigger (and costlier) problems later.
✅ What to do instead: Call a trusted aircon servicing company like Infinity Air at the first sign of trouble. Early diagnosis often prevents expensive repairs.
5. DIY Chemical Cleaning
While there are DIY guides and products available for aircon cleaning, chemical washes and overhauls should only be handled by certified professionals. Improper handling of chemicals or dismantling can lead to damaged parts, refrigerant leaks, or voided warranties.
✅ What to do instead: Hire a qualified technician for deep chemical cleaning or overhaul services. At Infinity Air, our team uses safe, NEA-compliant methods tailored to Singapore’s climate and common aircon models.
6. Blocking Airflow with Furniture or Curtains
Poor placement of furniture or curtains can block airflow around your aircon, making it work harder to cool the space. This reduces efficiency and creates uneven cooling across the room.
✅ What to do instead: Ensure that there is at least 1 metre of clearance in front of and around your aircon. Keep curtains and furniture away from vents to allow proper circulation.
7. Using the Wrong BTU for the Room Size
Choosing an aircon unit that’s too powerful or too weak for your room is a mistake often overlooked. In Singapore, where space is limited, people may install smaller units in large rooms or vice versa, leading to inefficient cooling and higher energy use.
✅ What to do instead: Always consult a professional to match the BTU rating to your room size and usage needs. Infinity Air provides expert guidance to help you select the right system for optimal performance.
