Selecting the correct horsepower (HP) for your room depends on its size. For smaller rooms (10–15 sqm), a 1.0 HP unit is sufficient. For larger rooms, you may need 2.0 HP or more. Rooms with high ceilings, large windows, or excessive sunlight may require a slightly higher HP for efficient cooling. Use this basic guide to choose the right aircon size for your needs:

Inverter air conditioners are more energy-efficient than non-inverter models. Inverters use variable speed compressors that adjust to the temperature needs of the room, reducing energy consumption. Non-inverter units operate at fixed speeds, consuming more electricity and offering less precise temperature control. Inverter aircons are generally quieter and more durable, making them a better long-term investment for energy savings.

Aircon HP (Horsepower) and TR (Ton of Refrigeration) are both units used to measure the cooling capacity of an air conditioner.

1.0 TR = ~1.3 HP or roughly 1.5HP

If your aircon is running but not cooling, there could be several reasons behind it. Common causes include low refrigerant levels, a clogged or dirty air filter, or a malfunctioning compressor. In some cases, the unit may just need a good cleaning to restore optimal performance. Regular maintenance can help ensure it operates efficiently and avoid these issues.

Water leaks from an aircon are often caused by clogged drainpipes, frozen coils, or dirty filters that block proper drainage. When airflow is restricted or the evaporator coils freeze, water backs up and starts to leak. To prevent this, it’s important to have your aircon regularly cleaned and maintained.

Routine servicing keeps filters clean, coils in good condition, and drainage lines clear—helping you avoid leaks, water damage, and costly repairs.

Yes, a dirty aircon can significantly impact its performance. When dirt and dust accumulate inside the unit, it reduces its cooling efficiency, forces the system to work harder, and increases electricity consumption. Moreover, neglecting cleaning can lead to internal damage over time, reducing the lifespan of your aircon. Regular cleaning and maintenance ensure that the system runs smoothly and efficiently.

A damaged fan motor in your aircon can cause weak airflow or even a complete failure of the unit to circulate air. This issue leads to poor cooling performance and may also cause the system to overheat, potentially causing further damage. If the fan motor is not repaired, the aircon may stop working altogether, and additional repairs may be necessary.

The evaporator coil is a vital component of your aircon, as it absorbs heat from the air inside the room and facilitates the cooling process. If the coil becomes dirty or clogged with debris, it can reduce the efficiency of your aircon, causing poor cooling performance. Regular cleaning of the evaporator coil is essential for optimal function and energy efficiency.

It is generally recommended to clean your aircon every 3-4 months to ensure it functions efficiently. For a more thorough cleaning, such as chemical cleaning of the internal parts like coils and the blower, it’s best to schedule it at least once a year. Regular servicing helps maintain air quality, improves cooling performance, and extends the life of your unit.

If your aircon starts producing weak cooling, you may notice ice buildup around the evaporator coils or hear a hissing sound, which indicates low refrigerant levels. In such cases, it’s time to call a certified technician to check and refill the refrigerant, as only professionals can handle this process safely. Avoid attempting to recharge the refrigerant yourself.

A bad smell coming from your aircon is often caused by mold, bacteria, or dirt inside the unit. When moisture accumulates in the system, it creates a breeding ground for these contaminants. This can lead to unpleasant odors in the air. Professional cleaning and servicing will help eliminate these smells and improve air quality by removing the buildup of bacteria and mold.

If your aircon turns off unexpectedly, it could be due to several issues such as a dirty unit, thermostat malfunction, or an automatic safety shutoff triggered by overheating. These problems can prevent the unit from functioning correctly, so it’s important to have the aircon inspected and repaired by a professional to avoid further issues.

While technically you can use an aircon without cleaning it, it’s not advisable. Over time, dust and debris accumulate in the system, which causes the aircon to consume more power and cool less efficiently. Additionally, failing to clean the unit regularly can lead to internal damage and costly repairs. Proper maintenance is key to ensuring your aircon operates effectively and has a longer lifespan.

With proper care and regular maintenance, an aircon can last anywhere from 10 to 15 years. The lifespan of the unit can be extended by cleaning it regularly, ensuring the filters are replaced, and servicing it at least once a year. Regular care not only improves efficiency but also reduces the likelihood of major breakdowns, ensuring that your aircon remains reliable for many years.

General cleaning refers to the basic cleaning of the aircon unit, such as dust removal from the filters, vents, and external parts. Chemical cleaning, on the other hand, is a deeper process that involves cleaning internal components like the evaporator coils, blower, and condenser, often using special cleaning agents to remove stubborn dirt, mold, or grime buildup. Chemical cleaning provides a more thorough service and restores optimal performance.

The cost of aircon cleaning varies depending on the type of unit, the level of service required, and the complexity of the task. Generally, a basic cleaning service is more affordable, while chemical cleaning or servicing of larger units may cost more. It’s always a good idea to contact your service provider for a quote to get an accurate price for your specific needs.

Yes, a dirty aircon can significantly increase your electricity bill. When dust, dirt, and debris build up inside the unit, it forces the aircon to work harder to cool the room, which in turn uses more energy. Regular cleaning ensures that the system runs efficiently, keeping electricity consumption low and reducing your energy costs.

Yes, it’s highly recommended to hire a professional for both installation and cleaning of your aircon. Incorrect installation can lead to leaks, poor cooling, or even damage to the unit. Similarly, DIY cleaning can cause more harm than good, leading to internal damage or voiding your warranty. A certified technician ensures proper setup and maintenance for long-lasting performance.

Weak airflow can be caused by various factors, including dirty filters, a blocked blower, or a malfunctioning fan motor. When airflow is reduced, it hampers the cooling efficiency of the system, and the room will take longer to cool down. Regular cleaning and prompt maintenance can usually solve this issue and restore proper airflow to your aircon.
