If you intend to install an aircon in your home, here are a few things to look out for before installing our aircon:

  1. Choose the best air-conditioner

The more common type of aircon used are wall-mounted air conditioners that come with the window unit. Wall units are fixed to the wall and cannot be moved, and it is connected to the outside of the wall too. A wall aircon installation may be pricey but it is more sustainable in the long run. However, window units can be installed without needing a professional aircon installer.

  1. Size of living area

Depending on the size of the room, the power of the air conditioner you choose may vary. Kitchen areas are normally warmer than the rest of the house and would need a higher BTU rating aircon. On average, a 5,000 BTU cooling capacity air conditioner is recommended for every 150 square feet of living space.

  1. Cost of electricity

Having a few air conditioners installed at home provides comfort for daily activities. On the other hand, running an aircon for several house could cost you nearly $150 monthly per unit, it is important you be thrifty. Be sure to lookout for energy efficient air conditioners in the future.

  1. Extra services and offers

Your aircon installation price may include optional upgrades or offers. These include maintenance and aircon servicing packages, and other warranties that you should consider. In such instances, we reckon that you go for it as it saves you money and reduces your liability if anything goes wrong.

  1. Recommended aircon services in Singapore

After deciding on the aircon brand, you should engage a reliable aircon servicing company to do the aircon installation. Find out from friends and family to get recommendations on the best aircon servicing companies in Singapore. Alternatively, you could use a trusted aircon installer in Singapore such as DW Aircon Singapore. We are able to care for your wiring, electric load, and do swift installation.



Before doing any aircon installation, here are certain things to take note to avoid the common mistakes during a Daikin aircon installation.

  • Choosing the wrong BTU

The British Thermal Unit (BTU) measures how fast an aircon can cool down a room. Depending on the room size and humidity of the room, choosing the right BTU for an air conditioner will help you be more energy and cost efficient.

  • Wrong aircon positioning

There are designated places to install an aircon that will ultimately save on your electricity bills, extend the lifespan of your aircon, and helps your room cool down efficiently.

  • Wrong thermostat positioning

The thermostat senses the temperature in a room and determines if it should be powered up or down. If the thermostat is installed near heat, it will encourage the aircon to work harder, increasing your electricity bills.

  • Not checking for leaks

Check the aircon gas levels and possible aircon leaks. To avoid any unnecessary expenses, be sure to re-evaluate your system. Hire our aircon servicing team to thoroughly check for potential leaks before installing your cooling system.



Like any other home appliance, there are also common problems with Daikin air conditioners.


  • Aircon leak

A Daikin aircon leaks when it breaks down. The aircon leakage usually is because of a clogged aircon pipe or a blockage in the evaporator coil, leading to condensation forming and seeping out. This is a sign that an aircon servicing is required.


  • Unable to switch on/off

In this instance, the wiring could be the problem. Our qualified technicians can check the wiring and perform an aircon repair when such a problem occurs. 

  • Failure to cool or heat

The problem lies with a faulty thermostat. The evaporating coil might also be frozen hence, it is unable to evaporate the cooling liquid into gas and absorb heat at the same time.

  • Refrigerant leaks

A leaking refrigerant can occur especially with cracked evaporating coils or holes, causing the whistling a hissing sound to emit from the aircon.

  • Noisy air conditioner

It could be due to a refrigerant leak, clogged fan coil, choked-up condenser, an off-kilter aircon blower and many others. An experienced aircon technician will be able to diagnose any underlying issues and recommend what are the next steps to take.



Although Daikin air conditioners are built to last, they too, require maintenance and cleaning to be functioning.

Clean Aircon Filters Dw Aircon Servicing Singapore_wm

  • Clean aircon filters

Daikin aircon’s filters work to prevent smoke, dirt, dust, and other harmful elements from entering in your premise. It requires regular cleaning to prevent common aircon issues. If you do not clean the filters regularly, its impurities will clog the airways and disallow your aircon from working in its full capacity and affects the energy efficiency. Apply the best filter cleaning techniques to keep your aircon filters clean and fully functional.


  • Clean the fan coil

Whenever you start using your Daikin aircon, ensure the cooling fan is perfectly clean. The top 3 aircon parts that require periodic care includes the fan coil. When not kept up with its maintenance, you will risk an aircon repair of the condenser fan. Dirt can accumulate on this fan that can affect its performance.

  • Exterior Maintenance

Why would I need a Daikin aircon replacement or repair?

Daikin air conditioners would require replacement and repair for obvious reasons such as an aircon leak, refrigerant leak, failure to cool or heat, and when it makes a hissing sound.


What are the symptoms that your aircon is failing?

These are the aircon repair symptoms you should note as it is a huge sign that your aircon is failing.

  • Aircon not blowing cold air  – Your aircon could be experiencing a weak air flow or blowing out hot air due to a faulty compressor or capacitor.
  • Gas pipe leakage – Unpleasant odor smells of poisonous Freon gas in your indoor unit or stained pipes could be the cause of a gas pipe leakage.
  • Water leakage – Water dripping from fan coils or build up of ice on the copper refrigerant lines are evidences of water leakage happening.
  • Aircon unit automatically switches off – This happens due to irregular servicing. A dirty aircon compressor or condenser can lead to overheating, causing the system to shut itself down. If still experiencing the same issue after cleaning, the issue lies with your thermostat.
  • Blinking lights – A warning sign that your aircon is experiencing problems that require immediate attention. Perhaps a faulty compressor, low refrigerant levels, electrical faults, or dirty filters.
  • Compressor stops running – Examine the start relay, capacitor, valves, and terminal connections. If they are not functioning as per normal, call DW Aircon Servicing and they will be able to solve this issue.
  • Emits foul odor – A pungent smell that comes from an air conditioner tells you that there is a burnt wiring or mouldy ductwork.


How many types of aircon repair are available in Singapore?

Here are the 6 aircon repair types available:

  • Aircon leak repair – The most common repair issue with air conditioners and knowing how to spot the leak is important. If the leak is persistent, it would decrease the refrigerant levels and create further issues.
  • Compressor repair/replacement – Since this system will run every time you turn your aircon unit, it is likely to experience electrical and motor problems. As this compressor problem requires complicated troubleshooting, engage in the services of an experienced aircon technician to solve the issue.
  • Fan motor repair/replacement – An aircon unit has two fans – the blower and condenser fan. The condenser is responsible for taking out the heat. Meanwhile, the blower pushes the cool air into the ductwork. Like other aircon parts, the fan’s motor, blades, and belts run into some problems after constant usage.
  • Circuit board repair/replacement – A sudden increase in electric voltage, a shortened wiring, or short circuit might happen as a result of pests and insects present.
  • Capacitor repair/replacement – When capacitors require repairing or replacement, it might be because of an overheating problem. If no attended to promptly, it could blow up fuses, leading to sudden shutdowns and humming sounds coming from capacitors.
  • Thermistor repair/replacement – If your air filter and fan motor seem to be in good working condition, then you might have a problem with your thermistor.
