Aircon is a must-have to beat the heat in warm climes such as Singapore. However, it requires constant maintenance to function and run at its peak. One of the most basic conditions required for maintaining aircon is a chemical wash. Most homeowners and business owners raise questions about what it is and when it is necessary. In this blog, we detail everything you need to know about chemical washes in aircon servicing.
What Is Aircon Servicing?
Aircon servicing is the scheduled check-up and cleaning of your aircon for it to effectively work and ensure effective time cooling or heating. It often encompasses cleaning filters, coils, and ducts, followed by leak checking and clearing off blockages. Nevertheless, time can pile up debris, mould, and contaminants in hard-to-reach areas. This is where a chemical wash comes in.
What Is a Chemical Wash in Aircon Servicing?
A chemical wash entails a much more intensive cleaning process for your aircon system. Technicians use chemical cleaning agents specifically designed to remove dirt, grime, and other impurities collected within your aircon’s internal components. Therefore, this service becomes necessary when regular cleaning no longer proves effective.
How Does a Chemical Wash Differ from Regular Servicing?
While a standard aircon service focuses on cleaning the external and accessible parts of the aircon, a chemical wash digs deeper.
- Regular aircon servicing typically involves cleaning the air filters, fins, and coils. It helps maintain day-to-day performance.
- Aircon chemical wash, on the other hand, involves dismantling the unit and using chemical solutions to thoroughly clean internal parts like the evaporator coils, fan coils, and drainage pipes. This ensures that any built-up dirt, mold, or grease is effectively removed, leading to better cooling performance and energy efficiency.
When Do You Need to Get an Aircon Chemical Wash?
When to obtain a chemical wash on your aircon in Singapore? Everyone is in a tizzy. There are some signs where it’s already time to have a chemical wash:
- Poor Airflow: You might find out that your aircon is not blowing air as it should be, and the culprit could be that it has gotten clogged up with dirt and debris inside. Chances are regular cleaning cannot effectively dislodge such stubborn blockages, and a chemical wash will be needed.
- Bad Odor: A pungent smell emitted by your aircon often indicates that mould, mildew, or bacteria are developing inside the equipment. With a chemical wash, you can be sure you will rid your room’s air conditioner of those pathogenic organisms which common servicing may not be able to remove.
- Water Leakage: Water oozing from your aircon is a sign that you may soon need a chemical flush. This is normally the case when the drainage pipes become clogged. At times, it becomes blocked due to dirt or mould, and it is only through a chemical wash that they are properly flushed to ensure there are no more leaks.
- Increased Electricity Cost: If your electricity bills shoot up without a reason or substantial increase in your use of aircon, then this may be a pointer to the overworking of your unit. Dirt and grime can give the best-blocked systems which causes inefficiency. A chemical wash is likely to restore the unit to its efficiency, with minimal consumption of energy.
- Frequent Breakdowns: If your aircon has just recently started breaking down frequently, it could be because of internal problems due to dirt and blockages. Chemical wash prevents this from happening because it ensures the unit gets cleaned out from the inside out.
How is a Chemical Wash Done?
Compared to normal servicing of aircon, a chemical wash is a more complicated procedure. The following is what usually happens with a chemical wash:
- Dismantling the Unit: The disassembly of the aircon involves removing the fan coil and the evaporator coil. This gives a technician access to areas that could not normally be seen.
- Chemical Applications: Technicians apply chemical solutions to the internal parts of the aircon. These chemical solutions break down the grime, dirt, and molds that accumulate in the system over time.
- Rinse and Cleaning: Technicians rinse the components with water to remove all dirt and chemical residues. They ensure all parts are free from obstructions.
- Reassembling: After cleaning, technicians carefully reassemble the unit. They check all parts for proper functioning.
- Testing of Unit: Finally, technicians perform aircon testing to verify efficient performance in terms of airflow, cooling capacity, and leakage.
Benefits of Chemical Wash
You may ask, why chemical wash and not the conventional aircon servicing? These are the benefits:
- High Efficiency: It will give your aircon an in-depth clean of its internal components and bring it to its top working ability. It can improve cooling so perhaps the better energy performance.
- Air Quality is Improved: Since a chemical wash removes mould, mildew, and bacteria from your aircon, this can improve air quality circulating in your home. Most affected people are those who suffer from allergies or respiratory complications.
- Long Life: Regular chemical washes prolong the lifespan of your aircon by preventing wear and tear from settling dust accumulation. This results in fewer breakdowns and replacements.
- Lower Energy Charges: A chemical wash restores efficiency to your aircon, which reduces electricity charges. An efficient aircon consumes less energy to cool your space, hence saving you money in the long term.
When Should You Schedule a Chemical Wash?
Now that you know the benefits, the next question is: how often should you get a chemical wash? In Singapore, the tropical climate can make aircon units work harder, leading to faster dirt buildup. Here are some general guidelines:
- For residential units, schedule an aircon servicing chemical wash every 6 to 12 months, depending on usage.
- For commercial units, plan for more frequent chemical washes every 3 to 6 months due to heavier usage.
If you’re unsure, consult a professional aircon servicing provider. They can assess your unit and recommend the right frequency based on its condition and usage.
Conclusion
Chemical washing is one of the major servicing practices regarding aircon, especially in countries like Singapore, with highly humid climate conditions. It cleans the inner parts more thoroughly for higher performance, better air quality, and lower energy costs. If your aircon suffers from weak airflow, bad smells, or water leakage, it’s probably time for a chemical wash. Many homeowners wonder when is aircon chemical wash needed in Singapore. Regular servicing and on-time chemical washes could extend the lifespan of your aircon while maintaining comfort indoors. For optimal performance, consult with the best aircon servicing company to keep it effective throughout the year.
