1. Importance of Air Conditioning Service and Cleaning

Air conditioning service and cleaning can help optimise energy efficiency and maintain good indoor air quality. Regular maintenance can extend your system’s lifespan and save on costly repairs, providing a healthier and cost-effective cooling solution for your home or office.
- Energy Efficiency
Routine maintenance of your air conditioner has the potential to significantly enhance its energy efficiency by ensuring clean filters and coils and reduced strain on the system, ultimately leading to reduced energy consumption. This is especially crucial in Malaysia’s hot and humid climate, where consistent air conditioning demands energy-efficient practices to save on costs and reduce environmental impact. - Air Quality
Clean filters and coils are essential for maintaining good indoor air quality as they are pivotal in air purification and allergen removal. Filters trap dust, pollen, and other particles, while clean coils enable efficient dehumidification, reducing mould and mildew growth. A well-maintained AC system cools your space and acts as an air purifier, creating a healthier indoor environment by minimising allergens and pollutants. - Cost Savings
Regular preventive maintenance is instrumental in prolonging your AC unit’s lifespan, reducing the likelihood of costly repairs or the need for a replacement. By addressing minor issues during timely servicing, you save on expenses and protect your AC system from developing into more significant problems, ensuring its long-term efficiency and reliability.
2. Air Conditioning Cleaning Tips You Can Do at Home

You can perform basic maintenance on your air conditioner to keep it running smoothly and extend its lifespan. Here is the step-by-step guide you can do at home to maintain your AC system in a top-notch condition:
Tools and materials you need:
- Screwdriver (if necessary to access components)
- Vacuum cleaner with a brush attachment
- Mild detergent (dishwashing liquid)
- Warm water
- A basin or sink
- Soft brush or sponge
- Towels or clean rags
- Fin comb (optional for bent fins)
Step 1: Turn Off and Unplug the AC
Ensure your air conditioner is turned off and unplugged to ensure safety while cleaning.
Step 2: Clean the Filters
Remove the air filter from the unit. Depending on your AC model, the filter may be washable or replaceable. If washable, clean it with a vacuum cleaner’s brush attachment or rinse it with water and mild detergent. Allow it to dry completely before reinserting it.
Step 3: Remove Debris
Use a vacuum cleaner with a brush attachment to clean any visible dust and debris from the interior components, including the evaporator and condenser coils, blower wheel, and drain pan.
Step 4: Clean the Coils
If the coils are particularly dirty, you can clean them as follows:
- Mix a mild detergent with warm water to create a soapy solution.
- Dip a soft brush or sponge into the solution and gently scrub the coils to remove dirt and grime.
- Rinse the coils thoroughly with clean water.
Step 5: Check the Condensate Drain
Inspect the condensate drain for blockages. If it is clogged, use a pipe cleaner or a small brush to clear the blockage. Ensure the drain is functioning properly to prevent water leaks.
Step 6: Straighten Bent Fins (if necessary)
If you notice bent fins on the condenser or evaporator coils, use a fin comb to straighten them carefully. This helps maintain proper airflow.
Step 7: Dry the Interior
Use towels or clean rags to dry the interior components after cleaning to prevent moisture buildup.
Step 8: Reassemble and Turn On the AC
Reinstall the cleaned filters and any components you removed. Turn on the air conditioner and check for improved airflow and cooling performance.
3. How Often You Should Clean Your Air Conditioner’s Filters

Daikin recommends cleaning the filters within your air conditioner’s indoor unit every two weeks. However, in environments with higher levels of dust or pollution, more frequent filter cleaning may be necessary.
This regular maintenance task is of utmost importance in air conditioner care. Clogged filters can significantly diminish the system’s efficiency, and replacing a dirty filter with a clean one can significantly reduce your air conditioner’s energy consumption, ranging from 5% to 15%.
4. When to Call a Professional Air Conditioning Service Provider

Taking care of minor issues can save you time, money, and future headaches. Keep an eye out for these warning signs that signal the need for professional AC repair to prevent more extensive problems. According to Total Air, here are the things you have to look out for:
- If the AC has weird smells
Detecting unusual odours from your AC unit or ducts, such as musty air, indicates potential mould growth. A metallic burning scent from the unit may also suggest issues with insulation or wiring. In both cases, it is essential to address these odours for the sake of your safety and well-being. - If the AC is not cold
The absence of cool air is the most evident indicator that it is time to contact your nearby air conditioning repair service. It is important to note that when your central AC fails to cool or operate, it does not necessarily signify a complete system failure. Multiple factors could be responsible, ranging from significant issues like a malfunctioning condenser to minor ones like a blocked filter. - If the AC makes buzzing sounds
Unusually loud buzzing or high-pitched screeching from your AC may suggest loose connections within the system or potential obstructions affecting the fan. It is advisable to contact a professional promptly to prevent further deterioration. - If the AC has moisture inside the vents or ducts
When moisture is detected in your ducts, it is a sign that humidity is infiltrating your living space. This issue may result from broken components, leaky ductwork, or a malfunctioning unit, which can strain your system, potentially leading to costly repairs or even a complete shutdown.
