Factors To Consider When Buying a Window Air Conditioner

Factors To Consider When Buying a Window Air Conditioner

Size of Window Type Air Conditioners

Importance of Room Size: 

It's not just about the physical size of the AC but also about its capacity to cool. A unit too small for a large room will work overtime, leading to higher electricity bills and reduced lifespan. Conversely, an oversized unit for a small room will cycle on and off frequently, consuming more energy and not dehumidifying properly.


Window Type Aircon Room Size

How to Measure and Choose: 

Start by measuring the square footage of your room. For every 20 square meters, you'd need roughly 5,000 BTUs (British Thermal Units) of cooling power. However, consider factors like ceiling height, insulation, and sunlight exposure. For instance, a room with large windows that get the afternoon sun might need a more powerful unit.

Budget Considerations and Getting Value for Money: 

While it's tempting to go for the cheapest option, it's essential to consider the unit's energy efficiency, durability, and features. Sometimes, spending more upfront can save you money in the long run through reduced energy bills and fewer repairs.

Features and Specifications: 

From the latest inverter technology that adjusts cooling based on room temperature to features like remote controls, timers, and air purifiers, modern window ACs come packed with functionalities. Decide which parts are must-haves for you and which you can do without.

Energy Efficiency: 

The Role of Inverter Type Window AC: Inverter ACs are the superheroes of energy efficiency. They adjust their speed to maintain a constant temperature, consuming less power and offering quieter operation. While they might be pricier initially, the savings on energy bills can make up for the cost difference over time.


While many window AC units are designed for DIY installation, some might require professional help, especially if you need to modify your window or wall. Consider installation costs and whether the unit comes with an installation kit. Also, consider the unit's weight and if you'll need an extra pair of hands to set it up.


How To Install Air Conditioner Window 

How To Install Air Conditioner Window

Wall Installation

If you have the permission (and the courage) to modify your home, consider creating a cutout in an exterior wall. This will allow you to mount the air conditioner similarly to how you would in a window. Seal the edges properly to prevent any air leaks or moisture ingress.

Partition Installation

If you live in a larger room or a studio apartment, you can create a partition or use an existing one to mount your air conditioner. This won't cool the entire space as effectively as a central position, but it's a viable option if you spend most of your time in a specific room area.

Ceiling Mount

Some modern air conditioners are designed to be mounted on ceilings. While not a traditional window type, these units can offer a solution for rooms without suitable windows.

Portable Air Conditioners

If installation becomes too tricky, consider opting for a portable air conditioner. These units can be moved around as needed and only require a small exhaust hose to be directed outside, often through a small hole or an existing vent.


Maintaining Your Window Air Conditioner: Tips and Troubleshooting

Essential Maintenance Tips:

Keeping your window air conditioner in top condition is key to prolonging its life and maintaining efficiency.

What to take note:

  • Regular maintenance tasks such as cleaning or replacing the air filter, ensuring the coils and fins are debris-free, and checking the unit's seals against the window can make a significant difference.
  • A clean air filter not only improves air quality but also enhances the efficiency of your window air conditioner, while clean coils and fins ensure the unit operates effectively.

Troubleshooting Common Problems:

  • Inadequate Cooling: If your window air conditioner is not cooling as expected, first check the thermostat settings and inspect the air filter for blockages. If the problem persists, it might be due to low refrigerant levels or a malfunctioning compressor.
  • Unusual Sounds: Rattling, buzzing, or other noises often suggest that parts within the unit may have loosened. Securing any loose components and ensuring the window air conditioner is mounted correctly can help eliminate these sounds.
  • Water Leaks: To prevent water from leaking inside, ensure your window air conditioner is installed with a slight backward tilt to facilitate proper drainage. Regularly check the drain pan and clear any blockages.
  • Persistent Odors: Replace or clean the air filter if you notice unpleasant smells. If the issue continues, a deeper cleaning of the evaporator coils might be necessary to remove mold or mildew buildup.

Is there a distinction between a Window Aircon Unit and an Aircon Window Unit?

Answer: "Window Aircon Unit" and "Aircon Window Unit" are often synonymous. Both denote air conditioning systems tailored to fit within a window frame snugly. However, in specific contexts, "Aircon Window Unit" might highlight the unit's seamless integration with the window structure, while "Window Aircon Unit" might emphasise its design and cooling capabilities.

Can you explain the workings of a Window Type Aircon Evaporator?

Answer: At the heart of a Window Type Aircon lies the evaporator. This component boasts coils filled with refrigerant. As the indoor air, carrying warmth passes over these coils, the refrigerant captures this heat, leading to its evaporation. This action cools down the air, which is then directed back into your space. The heat absorbed is subsequently released outside via the condenser.

Where's an excellent place to purchase an Aircon Unit in Singapore?

Answer: In Singapore, you're spoilt for choice when hunting for aircon units. From established electronic retailers to niche aircon boutiques and even digital platforms like Megafurniture, options abound. It's wise to compare prices, sift through customer feedback, and gauge after-sales support before finalising your buy.

How does a Window Air Con Unit stand apart from conventional AC systems?

Answer: A Window Air Con Unit is an autonomous apparatus tailored to nestle within a window's confines. It operates by pulling in ambient air, cooling it down, and dispatching the warm air outdoors. Conversely, a conventional AC, often dubbed a central air system, cools an entire property using an intricate duct network. It's typically more expansive and demands a more intricate setup.

My Window Aircon seems less effective. What could be wrong, and how do I address it?

Answer: A myriad of factors could dampen the efficiency of your Window Aircon. Frequent culprits include clogged filters, obstructed vents, dwindling refrigerant, or a glitchy thermostat. Initiate by inspecting and cleansing the filter, ensuring clear vent pathways, and adjusting the thermostat to your preferred setting. If these steps don't rectify the issue, calling an expert to assess refrigerant levels or probe the unit for other anomalies might be wise.
