This article is for homeowners who want to install window aircon in Singapore. Installing a window aircon is a practical solution for beating the heat in Singapore’s tropical climate. Window aircons are affordable, easy to install, and effective in cooling a single room or space. This guide will take you through the process of installing a window aircon in simple, easy-to-follow steps.

Install a Window Aircon

Singapore’s hot and humid weather makes air conditioning a necessity rather than a luxury. While there are many types of air conditioning systems available, installing a window aircon stands out for its simplicity and cost-effectiveness. Installing a window air conditioner in Singapore can be a do-it-yourself project, provided you follow the correct steps and safety precautions. 

Moreover, you need to keep in mind the challenges in window aircon installation if you adopt a DIY approach. This section will provide a comprehensive guide to help you install a window air conditioner with ease to ensure a comfortable and cool living environment.

Step 1: Gather Your Tools and Materials

The first installation step is always the tools and materials collection. You will need:

  • Window aircon unit
  • Measuring tape
  • Screwdriver 
  • Level
  • Pencil
  • Brackets and mounting hardware 
  • Foam insulation or weatherstripping
  • Safety goggles and gloves

Step 2: Choose the Right Window

Selecting the right window is crucial to install a window AC successfully. The window should be close to an electrical outlet, sturdy enough to support the weight of the aircon, and located in a room where you need the most cooling. Ensure the window opens vertically and has a sash that can be raised and lowered.

Step 3: Measure the Window Opening

Measure the width and height of the window opening to ensure your aircon will fit. Most window aircons are designed to fit standard window sizes, but it’s important to confirm this before proceeding. The aircon unit should fit securely in the window without any gaps.

Step 4: Prepare the Window

Before you install a window aircon, prepare the window by cleaning the sill and the surrounding area. Remove any obstacles or debris that might interfere with the installation. If the window has a screen, it’s usually best to remove it to allow for proper air circulation and easier installation.

Step 5: Install the Mounting Brackets

Most window aircons comes with mounting brackets to secure the unit in place. Follow the manufacturer’s instructions to install these brackets. Typically, you will attach the brackets to the window sill using screws. Make sure the brackets are level and securely fastened to provide a stable base for the aircon.

Step 6: Position the Aircon

With the help of another person, lift the aircon and carefully position it in the window. The bottom of the unit should rest on the mounting brackets, and the top should be held in place by the window sash. Slowly lower the window sash until it fits snugly against the top of the aircon, holding it in place.

Step 7: Secure the Aircon

To ensure the aircon is securely installed, use the included hardware to attach the unit to the window frame. This usually involves inserting screws through the sides or top of the unit into the window sash and frame. Make sure the aircon is level and firmly secured to prevent it from moving or falling.

Step 8: Seal the Gaps

To maximise the efficiency of your window aircon, seal any gaps around the unit. Use foam insulation to fill in the spaces between the aircon and the window frame. This will help keep the cool air inside and prevent warm air from entering the room. Additionally, it will improve the overall energy efficiency of the unit.

Step 9: Plug in the Aircon

Once the aircon is securely installed and the gaps are sealed, plug it into a nearby electrical outlet. Make sure the outlet is grounded and can handle the power requirements of the aircon. It’s a good idea to use a dedicated circuit for the aircon to prevent overloading the electrical system.

Step 10: Test the Unit

Before finalizing the installation, test the aircon to ensure it is working properly. Turn it on and set it to the desired cooling mode. Check for any unusual noises or vibrations that might indicate a problem with the installation. 

Ensure the air is flowing smoothly and the unit is cooling the room effectively. If you feel any issues, hire LS Aircon Servicing Singapore for their professional aircon installation, aircon chemical wash, aircon gas top-up, and aircon repair services.
