Air conditioning is essential for comfort in Singapore’s hot and humid climate. However, many homeowners still fall for common myths about air conditioners that lead to wasted energy, higher costs, and unnecessary repairs. By understanding the truth behind these myths, you can optimize your aircon’s performance, save on electricity bills, and extend its lifespan. In this guide, we will clear up the top 10 aircon myths and help you make better decisions for your home.
Myth 1: “Lowering the Temperature Cools the Room Faster”
Many people believe that setting the aircon to the lowest temperature will cool the room faster. However, this isn’t the case. Air conditioners cool at a consistent rate, no matter what temperature you set. Once your aircon reaches the desired temperature, it will continue to circulate cool air to maintain that level. Lowering the temperature simply forces the unit to work harder without any added benefit in cooling speed. This can lead to higher electricity consumption and unnecessary wear on your system.
To maximize energy efficiency, it’s best to set the temperature between 23°C to 25°C. This is usually enough to keep your home comfortable while reducing power usage. Additionally, using programmable timers can help ensure that the aircon is only running when necessary, further saving energy.
Myth 2: “I Don’t Need Servicing If My Aircon Is Still Cold”
It’s a common misconception that aircon servicing is only necessary when the unit stops producing cool air. Just because your aircon is blowing cold air doesn’t mean it’s running efficiently. Over time, filters can clog with dust, and internal components like coils and refrigerant levels can degrade. Without regular servicing, these issues may go unnoticed, affecting the system’s performance and leading to higher energy consumption.
Regular servicing, at least every six months, helps keep your aircon in top condition by ensuring that components are cleaned, the refrigerant is properly charged, and the system is functioning efficiently. Neglecting this can result in poor cooling, increased repair costs, and a shorter lifespan for your aircon. To keep your unit running efficiently and avoid hidden clogs, schedule a general aircon servicing at least once every six months.
Myth 3: “Bigger Aircon = Better Cooling.”
Many homeowners believe that a larger aircon will provide better cooling, especially in bigger rooms. However, this is not true. Air conditioners need to be properly sized to match the room’s cooling needs. An aircon that’s too large for a room will cool the space too quickly, leading to uneven temperatures and more frequent on/off cycling. This wastes energy and reduces efficiency. On the other hand, an undersized aircon will struggle to cool the room, leading to overworking and higher electricity usage.
Choosing the right BTU for your room size is critical. A professional assessment of your home’s cooling needs can help you choose the right aircon for maximum efficiency.
Myth 4: “Running the Aircon 24/7 Is Fine as Long as the Temperature Is High”
Some homeowners think that leaving their aircon running 24/7 with the temperature set high is a good way to maintain a cool home. In reality, running your aircon non-stop, even at a higher temperature, puts unnecessary strain on the unit. Continuous operation leads to excessive energy consumption, and it can cause wear and tear on the components, shortening the lifespan of the aircon.
It’s better to set the aircon to operate in cycles. Use a timer or a smart thermostat to control the aircon’s usage and ensure it runs only when necessary. This method allows the unit to rest, saving energy and extending its life while still keeping your home comfortable.
Myth 5: “Chemical Wash or Overhaul Is Needed Every Year”
A common belief is that chemical washes or overhauls are required every year to keep an aircon running smoothly. While these services are necessary in some cases, they are not needed annually for most systems. Chemical washes and overhauls are typically required when there is a buildup of dirt, mold, or bacteria, or if the unit has not been maintained properly for an extended period. Regular servicing, which includes cleaning filters and checking refrigerant levels, is often sufficient to keep your aircon in good condition.
Overdoing chemical cleaning can actually damage your unit, so it’s important to follow a recommended schedule. For most aircons, a chemical wash or overhaul should be performed every two to three years, depending on usage and the environment.
Myth 6: “Aircons Don’t Cause Allergies, Only Dust Does”
Many people think that air conditioning units are harmless when it comes to allergies, attributing allergy symptoms only to dust. However, aircon units can actually contribute to allergy symptoms if they’re not properly maintained. Dirty filters, clogged coils, and accumulated mold can all cause allergens like dust mites and spores to circulate through your home. This poor indoor air quality can worsen respiratory problems and allergies, particularly in a humid climate like Singapore.
To prevent this, it’s crucial to clean or replace aircon filters regularly. Scheduling professional aircon servicing can also help ensure that mold and bacteria are removed, and your aircon is circulating clean, healthy air.
Myth 7: “All Aircon Servicing Companies Offer the Same Quality”
Many homeowners assume that all aircon servicing companies offer the same quality of service, often choosing based on the lowest price. However, this is a misconception. Not all aircon servicing companies are equal in terms of expertise, equipment, and reliability. Some may cut corners, offering quick fixes that don’t address the root cause of the problem, while others provide thorough, professional servicing that ensures your aircon’s longevity.
Choosing a reputable company like LS Aircon Servicing Singapore ensures that experienced technicians are handling your aircon with the proper tools and knowledge. Look for companies with positive reviews, a solid track record, and certifications from trusted industry bodies. Quality service prevents issues from recurring and saves you money on repairs in the long run.
Myth 8: “Closing Windows and Doors Maximizes Aircon Efficiency”
Another common myth is that closing all windows and doors will make your aircon work more efficiently. While it seems logical to seal a room to keep the cool air in, this can actually backfire. Air conditioners rely on proper airflow to maintain efficiency. Sealing the room too tightly can trap moisture, increase humidity, and reduce air circulation, all of which can make it harder for your aircon to cool the space effectively.
Instead, ensure proper ventilation in your home. While you should close windows to prevent hot outdoor air from entering, leaving small gaps for airflow or using a vent in larger rooms can help maintain a balance between cooling and air circulation. This will allow your aircon to work more efficiently without overexerting itself. Check the NEA Energy Label on your unit to understand its efficiency rating and how setting a moderate temperature helps you save more
Myth 9: “Aircons Only Need Servicing When They Stop Working”
Some homeowners believe that aircon servicing is only necessary when their system stops working completely. However, this myth can lead to expensive breakdowns and repairs. Aircon issues often develop gradually, with symptoms like poor cooling or strange noises that go unnoticed until the system completely fails. It’s always better to service your aircon regularly before it shows signs of major issues.
Preventive maintenance, including cleaning filters, checking refrigerant levels, and inspecting the system for wear and tear, helps keep your aircon running smoothly and extends its lifespan. Regular servicing can catch minor issues early, preventing costly repairs and prolonging the life of your aircon.

Myth 10: “Aircons Are Expensive to Maintain”
Many homeowners shy away from regular servicing because they assume that aircon maintenance is costly. However, this isn’t necessarily true. Regular servicing is an investment that helps you avoid more expensive repairs or even replacement down the line. In fact, the cost of routine servicing is much lower than the cost of repairing a unit that has been neglected for too long or replacing an old, inefficient aircon.
By maintaining your aircon properly, you can save money on energy bills and ensure that your unit continues to operate at peak efficiency. Additionally, the longer your aircon lasts, the more value you get out of your investment. For affordable and reliable servicing, consider booking a session with LS Aircon Servicing.
Expert Tips for Maximizing Aircon Lifespan & Efficiency
Avoid Extreme Temperature Settings
Setting your aircon to a very low temperature might seem like an easy way to cool the room quickly, but it actually causes unnecessary strain on the system. Air conditioners are designed to cool at a consistent rate, and setting the temperature too low will force the unit to work harder, leading to higher energy consumption and increased wear on the system. For optimal efficiency, keep your aircon’s temperature between 23°C to 25°C. This range is typically sufficient to maintain a comfortable environment while keeping energy costs down.
Use a Timer or Smart Thermostat
To avoid running your aircon unnecessarily, consider using a timer or smart thermostat. These tools can help you control when the aircon is running, ensuring it’s not operating when you’re not home or when the room doesn’t need cooling. A smart thermostat can even learn your schedule and adjust the temperature accordingly, which can lead to significant energy savings. Using these devices not only improves comfort but also reduces the overall strain on your aircon, leading to a longer lifespan and lower electricity bills.
Clean or Replace Filters Regularly
Aircon filters play a critical role in maintaining air quality and ensuring the unit operates efficiently. Over time, filters can become clogged with dust, dirt, and other debris, which can reduce airflow and force the aircon to work harder. This can lead to increased energy consumption and decreased cooling performance. To keep your system running smoothly, clean or replace your filters every 1-3 months, depending on usage. Regular maintenance of filters also helps ensure that the air circulating through your home is clean and free of allergens.
Keep Your Home Well-Insulated
Proper insulation and shading in your home can help reduce heat gain and make it easier for your aircon to maintain a cool temperature. Without adequate insulation, heat from the outside can enter your home, forcing your aircon to work overtime to cool the space. By installing high-quality insulation in walls, ceilings, and windows, you can minimize heat transfer and reduce the workload on your aircon. Additionally, using curtains, blinds, or window films to block sunlight can further help keep your rooms cooler and reduce the energy your aircon needs to use.
Schedule Regular Professional Servicing
Even though cleaning filters and checking the unit yourself can help maintain your aircon, professional servicing is essential for ensuring the system runs at its peak. Regular professional servicing can identify and resolve minor issues before they become major problems, preventing costly repairs and improving your unit’s overall efficiency. Schedule servicing every 6 months to check for any refrigerant leaks, clean the coils, and ensure all components are functioning properly. A well-maintained aircon not only cools better but also consumes less energy, saving you money in the long run.
