5 Air Conditioning Mistakes To Avoid In Singapore

Due to the intense heat in Singapore’s tropical environment, air conditioning is a must for both residential and commercial buildings. However, in an attempt to stay cool, a few frequent mistakes with air conditioning can lead to discomfort, inefficiency, and unnecessary expenses. This extensive guide explores some common air conditioning mistakes to avoid.

1. Choosing the Wrong Unit

Selecting a suitable air conditioning unit is not merely a matter of preference; it is an important decision that impacts its efficiency and longevity.

Within Singapore’s urban landscape, the size of the unit must align precisely with the environment’s cooling demands. Usually, an oversized unit will run for short periods, resulting in frequent on-off cycles and inadequate cooling, while an undersized unit will run continuously but fail to achieve the desired cooling effect, leading to increased wear and tear.

The measurement unit used for air conditioning systems in Singapore is typically the same as the British Thermal Units (BTUs), So here’s a breakdown of recommended British Thermal Unit (BTU) for different-sized rooms :

  • Small room (50 to 250 square feet): 5,000 to 6,500
  • BTU mid-size room (250 to 350 square feet): 7,000 to 8,500
  • BTU large room (350 to 650 square feet): 9,500 to 12,500

To avoid this common air conditioning mistake, a simple rule of thumb is to ensure that your air conditioner emits approximately 20 BTU per square foot. So, when you select a suitable-sized air conditioning unit, you will enjoy optimal performance while reducing potential pitfalls.

2. Neglecting Yearly Maintenance

Yearly maintenance is crucial because Singapore’s climate, with its constant and sometimes unpredictable heat and humidity, demands a lot from air conditioning systems. These yearly maintenance appointments serve as crucial checkpoints to ensure your air conditioning unit’s optimal performance and longevity.

Just like any mechanical system, air conditioners require aircon servicing and maintenance by experts to detect and rectify issues before they escalate into major malfunctions. One of such experts in Singapore is LK Brothers.  Failure to schedule annual aircon maintenance can lead to various problems, including;

  • inadequate refrigerant levels
  • clogged filters
  • malfunctioning component.

These, among many other issues, can arise more frequently if left unchecked, causing severe damage. For instance, insufficient refrigerant levels can affect the air conditioner’s ability to cool effectively, resulting in discomfort and higher energy consumption. Clogged filters not only reduce airflow, hindering the unit’s cooling capacity, but also compromise indoor air quality by allowing dust, dirt, and other pollutants to circulate throughout the environment.

In Singapore, where indoor air quality is paramount for occupant health and comfort due to Lion City’s highly populated urban environment, neglecting maintenance can have adverse effects on occupants’ respiratory health and overall well-being.

Individuals can prevent such typical aircon problems and guarantee the dependability and efficiency of their air conditioning systems by keeping up with their annual maintenance or chemical wash schedule with qualified technicians who can help maximise performance and avert future breakdowns by simply carrying out comprehensive inspections, cleaning components, lubricating, moving parts and making required adjustments.

3. Setting the Temperature Too Low

A prevalent misconception among air conditioner users is that lower temperature settings equal faster cooling. In reality, excessively low thermostat settings only strain the entire system and increase energy consumption.

Excessive temperature reduction shortens the life of your air conditioning equipment and increases monthly expenses. But we understand situations where your living area seems extremely hot; caution is difficult to remember. We advise you to utilise the settings on your programmable thermostat rather than turning down the temperature as soon as you arrive home.

Have you not yet purchased a programmable thermostat? Even if a complete replacement of your AC system is not automatically necessary, you may, nonetheless, get a new one from an expert in Singapore. You can reduce a lot of expenses if you know how to properly control your thermostat, especially when you are not at home or out on a family vacation; you can set the AC to turn off automatically.

You may even program the system to turn back at a specific time before you arrive, so when you go home, it will be cool, cosy, and nice. So, by simply adopting moderate temperature settings, home and business owners can strike a balance between comfort and energy efficiency, thereby optimizing the performance of the air conditioning systems.

4. Neglecting Thermostat Maintenance

The thermostat serves as the control centre of an air conditioning system. It works by signaling the unit to produce the desired temperature in the living space. Other components in the HVAC system help carry out this important function, providing you with cool or warm air, depending on your preferred temperature setting.

Thermostats for air conditioning units typically fall into these categories:

  • mechanical
  • electronic
  • programmable

Thermostats are frequently sensitive to adjustments, particularly if you own a digital or programmable kind. Your thermostat may require a proper repair if you discover that it is not responding to taps or clicks. Not only could the thermostat require new batteries, but it might also have poor connections to its circuit.

An air conditioner that quits in the middle of heating or cooling a room is another obvious indicator that the thermostat is broken. Short cycling is the term for the brief on/off periods that your air conditioner may experience.

There is a possibility that the unit is receiving incorrect signals from your thermostat, and if left unchecked, thermostat malfunctions can lead to uneven cooling distribution and increased energy consumption.

Regular inspection and calibration of thermostats are essential to rectifying discrepancies and upholding system efficiency. Because of their complexity and reliance on wired programming, electrical circuits, and hazardous mercury, thermostats may be challenging for the typical homeowner to operate.

It is best to leave the job to trained technicians skilled in identifying and fixing thermostat issues.

5. Aircon Maintenance Mistake: Overlooking Filter

An air filter is a crucial component in maintaining the performance of air conditioners. They trap all airborne contaminants to ensure that only clean air circulates through your indoor environment. These filters protect the mechanics of the air conditioner unit and your home’s air quality.

As air moves through the HVAC system, it passes through these filters before being heated or cooled and then recirculated into your living spaces. High-quality filters with higher Minimum Efficiency Reporting Value (MERV) ratings are capable of capturing smaller particles more effectively than those with lower ratings.

This filtration process is critical for preventing harmful particles from clogging up the inner operations of heating and cooling units while also contributing to a healthier indoor climate.

Overlooking filter maintenance can diminish cooling efficiency, impede airflow, and aggravate respiratory issues.

To maintain optimal system performance in areas where air pollution levels are a concern, regular filter replacement is essential. People can reduce energy consumption use, increase the longevity and efficiency of their air conditioners, and improve indoor air quality by following a regular schedule for filter maintenance. Experts at LK Brothers Engineering advise points towards swapping out dirty filters every three months at least to keep your AC units running smoothly and avoid unnecessary damage to its parts.

Other Common Usage Mistakes To Avoid With Aircons In Singapore

Installing an aircon in your home in Singapore is great, but here are some basic aircon mistakes to avoid when using it.

Improper Ceiling Fan Usage

Although cooling through the aircon suits the hot weather of Singapore, using it 24/7 can quickly cause damage to the device. You should avoid the mistake of not using ceiling fans as an alternative. Having an alternative can prolong your aircon life and also be of supplementary usage on days with lesser heat.

We encourage you to install your fans in positions that will aid in blowing a cool breeze down. Air circulation and speed of receiving cool breeze should always be considered. Ceiling fans are also cheaper, so this makes it very ideal to use them to supplement Air conditioner usage.

Keeping Your Aircon Unused For A Long Time

Another mistake you should avoid is keeping your aircon for so long without using it. It’s fine to keep the aircon off if you’re not around, but not using it for a long time will affect the mechanics. For instance, you need to get rid of rust by using it, and animals can easily nest in your AC if it is not regularly used.

Also, not using it for long periods of high temperatures can affect your home. The heat can spoil your flooring, cabinets, or wood doors. Ensure you properly use your Aircon during these warmer periods.

Turning The Aircon Unit On And Off Frequently

You should stop if you’re fond of frequently turning your aircon on and off. It’s ok to try easing your aircon from the stress of working 24/7 that’s superb. But doing this more often can cause more harm than good to it. The compressor and fan will feel the stress of having to pick off frequently within short periods. To prevent stress for your aircon, consider putting it on during the day and putting it off at night. This will also reduce the cost of electricity.

Enhancing Cooling Efficiency: Two Techniques for Singaporeans

Increasing cooling efficiency is essential to ensuring comfort, reducing energy use, and mitigating the natural effect of Singapore’s continual heat and humidity. This section examines important protocols and best practices to enhance cooling efficiency and make the Lion City more comfortable.

1. Saddling Savvy Technologies

Embracing shrewd advances holds tremendous potential for altering cooling productivity in Singapore. Brilliant indoor regulators, outfitted with cutting-edge sensors and calculations, empower exact temperature control and versatile cooling systems. Smart cooling systems can intelligently adjust cooling yield based on population patterns, weather data, and customer preferences by leveraging data analysis and AI computations.

Furthermore, remote monitoring and control features encourage users to use less energy, spot anomalies, and look into problems gradually, increasing system dependability and productivity.

2. Putting resources into Environmentally friendly power Integration

Singapore’s ability to adopt renewable energy will determine how successful it is in pursuing a cool and sustainable future. The government’s Green Plan 2030, which outlines tactics to promote renewable energy sources like solar and wind, acts as a road map.  Imagine an island nation’s rooftops and facades serving as active contributors to a greener energy grid rather than merely serving as spaces for introspection. Silently absorbing the plentiful sunshine, solar photovoltaic (PV) panels convert it into clean electricity for our air conditioners, an essential device in Singapore’s hot and muggy environment.

By lowering dependency on fossil fuels, this adjustment not only mitigates climate change but also makes one feel good about themselves. Rather than being passive energy users, we actively contribute to making the environment a greener and more sustainable future.

Wind power, while facing some limitations due to Singapore’s geography, also holds promise. An article by Channel News Asia explores advancements in turbine technology, making even gentle breezes a viable source of clean energy. Imagine strategically placed wind turbines, perhaps along coastlines, working in tandem with solar panels. These towering giants would harvest the power of wind, further contributing to the clean energy mix that’s much needed.

The concept of microgrids, highlighted in a policy brief by the International Renewable Energy Agency (IRENA), adds another layer of intrigue.  Microgrids are localised energy networks where communities can generate and consume their own power, potentially using a combination of solar and wind. 

Imagine residential and commercial areas where solar-powered rooftop panels power local power systems. This lessens reliance on the main power grid, which could increase air conditioner efficiency, and it also encourages a sense of communal responsibility in the battle against climate change.

By strategically integrating these renewable energy sources, Singapore can move towards a future where sunshine and wind aren’t just environmental elements but the silent workhorses powering our air conditioners and fostering a cooler, more sustainable future for all.
