Aircon Service 101 : Frequently Asked Questions and Expert Answers

Air Conditioners, we love them and we use them to beat the heat of the hot Asian weather every day. However, proper aircon service is crucial to ensure these systems operate efficiently.

Understanding the basics of aircon service can help users make informed decisions and maintain optimal performance.

Here are some of the most common questions and answers regarding aircon services :


Common Frequently Asked Questions


1. What is the importance of regular aircon servicing?

Regular aircon servicing is essential to maintain the efficiency and longevity of your cooling system.

Optimal Performance: Regular servicing ensures your unit operates at its peak efficiency, providing maximum cooling while consuming less energy.

Longevity: Proper maintenance can extend the lifespan of your air conditioner, saving you from premature replacements.

Improved Air Quality: Cleaning filters and components eliminates dust, pollutants, and allergens, contributing to better indoor air quality.


2. How often should air conditioners be serviced?

The frequency of servicing depends on various factors, including usage, climate, and manufacturer recommendations.

As a general guideline, it’s advisable to service your air conditioner at least once a year. 

However, in high-usage or dusty environments, you may need to have your aircon serviced more often than usual.


3. What are the signs that indicate the need for aircon servicing?

The signs that indicate your aircon may need some servicing are as follows:

Reduced Cooling – If you notice that your AC isn’t cooling as effectively as before, it might need cleaning or repairs.

Unusual Sounds or Odors – Strange noises or odors could indicate underlying issues that require professional attention.

Increased Energy Bills – A sudden rise in energy consumption can indicate an inefficient system in need of servicing.


4. What causes water leaks from aircon

Water leaking is usually caused by a clogged drain line but there are other reasons as well such as a dirty air filter, the refrigerant containment being broken, or some other faulty components. 

If you have spotted that your aircon is leaking, It is best to call a professional to inspect the aircon.


5. What to do when the aircon is not cooling as effectively?

There are many reasons as to why your air conditioner is not as effective at cooling as it was prior. This is why it is important to know some
aircon troubleshooting.

Here are the simple steps to fixing this issue :

The first step is to check the aircon filters. A caked-up air filter is the most common reason as to why your aircon is not cooling as effectively. Try to take out the filter and clean it up to allow proper airflow from the aircon.

If that does not work, It could be a deeper issue with your aircon which would be a dirty condenser. A dirty air condenser causes your aircon to need to work harder to pull in air and it would cause your aircon to not blow air effectively. To clean the condenser, many people like to do chemical cleaning.

If your aircon is still not fixed after all these steps, it would be a good idea to have an expert help on the matter.


6. Why is my aircon making weird sounds?

Weird sounds would usually indicate an internal problem that needs to be resolved quickly. 

The common issues that would cause noise would be debris inside of the aircon, a loose component inside of the aircon, or there is a problem with the motor of the aircon.

To fix this issue, it is a good idea to have a technician take a look at your aircon to identify and replace the broken components inside of the aircon.


7. Can I Service My Air Conditioner Myself?

While some maintenance tasks like filter replacement can be done by homeowners, comprehensive service is best left to professional technicians. 

They have the expertise to identify and address potential issues, ensuring the system’s proper functioning.


8. How Can I Choose the Right Size Air Conditioner for My Space?

Choosing the right size air conditioner for your space is crucial for ensuring optimal performance, energy efficiency, and comfort.

An air conditioner that is too small may struggle to cool the area effectively, while one that is too large may cycle on and off frequently, leading to energy waste and potential issues.

Many people tend to buy their aircon based on the square footage of the room they want to cool.


9. When Should I Consider Replacing My Air Conditioner?

Knowing when to replace your air conditioner involves considering factors such as age, repair frequency, declining efficiency, and increased energy bills. 

If your system is over 10-15 years old, requires frequent repairs, or experiences a significant drop in efficiency, investing in a new, more energy-efficient model may be a wise decision.

When considering the replacement of your air conditioner, it’s essential to consult with a professional aircon technician

They can assess your current system, evaluate your specific needs, and recommend the most suitable replacement option based on factors such as the size of your home, climate, and budget.


10. Is it normal for my air conditioner to produce a musty smell?

No! A musty smell may indicate mold or mildew growth in the system, particularly in the evaporator coil or ductwork. 

It’s essential to address this issue promptly to prevent further air quality and health concerns.


11. What is the role of refrigerant in my air conditioner?

Refrigerant is a crucial component that absorbs and releases heat, allowing the air conditioner to cool the indoor environment. 

These substances undergo a continuous cycle of evaporation and condensation within the air conditioning system, facilitating the transfer of heat between the indoor and outdoor environments.

Common types of air conditioning refrigerants include:

R-22 (Freon): R-22 was a widely used refrigerant in air conditioning systems. However, due to its negative impact on the environment, particularly its ozone-depleting properties, its production has been phased out, and it is being replaced by more environmentally friendly alternatives.

R-410A: R-410A is known for its higher efficiency and is commonly used in residential and commercial air conditioning units.

R-32: Another HFC refrigerant, R-32, has been gaining popularity due to its lower global warming potential (GWP) compared to some other refrigerants.

R-134a: Commonly used in automotive air conditioning systems, R-134a is a hydrofluorocarbon that does not contain chlorine. 

R-290 (Propane): R-290 is a hydrocarbon refrigerant that has gained attention for its low GWP and ozone-friendly properties.

Low refrigerant levels can lead to decreased cooling efficiency.


12. Are there energy-saving features in modern air conditioning systems?

Yes, modern air conditioning systems often come equipped with various energy-saving features designed to enhance efficiency and reduce energy consumption.

These features contribute not only to lower utility bills but also to a more environmentally friendly operation. 

An example would be daikin’s inverter technology that is used on their air conditioner unit to save more than 50% of the energy.



By understanding these frequently asked questions and their detailed answers, you are better equipped to make informed decisions that contribute to the longevity and efficiency of your air conditioning system.
