If you do not service your aircon in the previous year, I will make the aircon struggling this summer. As temperatures rise across Singapore this summer, many individuals find themselves sweating indoors despite turning their cooling system to full blast. Most of the population is experiencing the same frustrating problem: aircon struggling this summer.
With the highest ever temperatures and persistent humidity, air conditioners are working harder than ever in Singapore, which in some cases has led to their failure as well. This raises an important question among every individual: Why is my aircon struggling this summer? In this article, we’ll explore seven reasons behind this issue that will help people develop a thorough understanding to get the system running smoothly again.
Reasons Why My Aircon Is Struggling This Summer?
Several reasons help us understand why my aircon struggling this summer. From wear and tear due to constant use to environmental and maintenance-related issues, all contribute to aircon struggle this summer. Discussed below are the seven most common reasons of aircon problems during the scorching heat this summer.
1. Dirty Air Filters
One of the most common reasons why my aircon is struggling this summer is a clogged or dirty air filter. In Singapore’s dusty and populated urban environment, air filters easily get blocked by particles, allergens, and even mold spores.
This results in airflow restriction, which makes it harder for air conditioner to cool the room effectively. Replacing or cleaning the filter monthly, especially during high-use months like June and July, makes a notable difference in performance.
2. Low Refrigerant Levels
Low refrigerant levels are the second most common reason that leaves every person wondering why the air conditioner is struggling this summer. Refrigerant is the lifeblood of the cooling system, and without the proper level, the unit cannot absorb and remove heat from the desired area efficiently. Leaks in the refrigerant lines damage the environment and disturb our comfort.
This issue requires immediate attention from a certified technician, such as those from LS Aircon Servicing Singapore, who can safely check and refill refrigerant levels. They offers you aircon relocation, aircon chemical overhaul, and Gas Top Up in Singapore.
3. Blocked Condenser Coils
The condenser unit, typically located outside, plays a crucial role in removing the heat extracted from the desired space. However, in a city like Singapore where plant debris, construction dust, and pollution are common, these coils become dirty. This restricts heat transfer and causes AC struggling this summer. Regular maintenance helps to restore the system’s efficiency.
4. Thermostat Issues
Another often overlooked reason behind aircon struggling this summer is a malfunctioning thermostat. Whether it’s a calibration issue, dead batteries, or an outdated model, an inaccurate thermostat sends mixed signals to the cooling system.
This results in erratic cooling cycles or failure to reach the desired temperature. If the room feels warmer than the set temperature, it is time to upgrade to a smart or digital thermostat for better control.
5. Undersized Aircon Unit
Renovation or adding more people to a space changes the cooling requirements of that area. An air conditioner struggling this summer is also a sign that it lacks the capacity to cool a larger or sun-drenched room.
This is especially true in areas with poor insulation or direct afternoon sun. Consulting experts like LS Aircon Servicing Singapore help determine if an upgrade is needed for the space.
6. Poor Airflow Due to Ductwork Problems
In many HDB and condo units, ductwork becomes leaky, twisted, or improperly sealed, leading to a drop in air pressure and efficiency. If you feel that certain rooms are cooler than others or airflow is inconsistent then ductwork is to be inspected. This hidden issue is a silent contributor which leaves a person wondering why is my aircon struggling this summer. It requires expert evaluation and sealing.
7. Lack of Regular Maintenance
The most evitable cause of an AC struggling this summer is poor maintenance. Air conditioners need regular servicing to operate at peak performance. Filters, coils, fans, and electrical components all benefit from routine checkups. Partnering with a trusted local provider such as LS Aircon Servicing Singapore ensures that potential issues are caught at the earliest and the unit runs smoothly throughout the season.
Conclusion
In conclusion, if you do not clean it previously, it will result in the aircon struggling this summer. Singapore’s relentless summer heat puts even the most resilient air conditioners to the test. But when the aircon is struggling this summer, it’s not just the weather to blame. From clogged filters and low refrigerant to thermostat malfunctions and poor maintenance, there are several factors that hinder the performance of the cooling system.
By understanding the reasons why my aircon is struggling this summer, I will take informed steps toward a solution. Whether it’s a simple filter change or a professional inspection by LS Aircon Servicing Singapore, timely action restores comfort. To understand aircon struggles this summer, always remember that the solution lies in maintenance, environment, and system design.
