Keeping your air conditioner in good condition is crucial, especially in Singapore’s tropical climate. It can help to improve your comfort and ensure that the air conditioner can work efficiently at all times.

There are two methods that people go for to clean their air conditioner: the aircon chemical wash and steam cleaning. Each method has its pros and cons, making the choice a bit tricky. But don’t worry—we're here to break down the differences between aircon steam cleaning and chemical washing for air conditioners. By the end, you’ll know exactly which option is the right fit for your needs

What is a Chemical Wash?

An air conditioner chemical wash is a comprehensive cleaning procedure that involves partial dismantling of the air conditioning unit and using specialized chemicals to deeply clean and restore the internal components of the air conditioner. 

Many often confuse chemical wash with a chemical overhaul, due to the use of the name “chemical”. A chemical overhaul is a more thorough process that involves the full dismantling of the air conditioning unit and chemically cleaning each part separately to ensure the cleaning solution reaches all areas of your unit, effectively flushing out any built-up dirt and debris.

The chemicals used for chemical washing in the aircon are typically acidic solutions that were designed to break down and dissolve accumulated materials inside the air conditioner. Each component of the aircon, including the blower and fan coil is chemically cleaned, and the drain pipe will be flush and serviced to ensure it is clear of any blockages. The fan coil, filter, and water tray will also be cleaned to remove dirt, and bacteria, and prevent mold buildup. Additionally, the air gas levels will also be inspected for leaks to ensure optimal performance.

A chemical wash is a great method that any AC owner should do once in a while to remove stubborn dirt, debris, and unpleasant odors from their air conditioner unit!

Advantages of Chemical Wash

  • Effective for Deep Cleaning: During the chemical wash all the components of the air conditioner will be washed with a specialized chemical solution, this method is great and effective in removing any dirt, contaminants, and stubborn deposits inside the air conditioner. A perfect solution to deep clean your air conditioner!
  • Improved Unit Efficiency: A thorough cleaning can help the air conditioner to run more efficiently as all the buildup of dirt and debris can be removed effectively.
  • Long-Term Protection: Some chemical solutions can also create a protective layer that reduces future dirt accumulation. So, it won't only clean the air conditioner but also act as a preventative solution to protect it.

Disadvantages of Chemical Wash

  • Utilize Chemical Use: The only disadvantage of utilizing chemical wash for aircon is due to the chemicals involved during the cleaning. Some people might not want to utilize chemicals because they are afraid they may pose environmental and health risks if not properly handled. 

What Is Aircon Steam Cleaning?

Steam cleaning uses high-pressure steam to eliminate all the dirt and contaminants that exist inside the air conditioner. Water is heated to high temperatures and forced through a nozzle or wand, creating a powerful stream of steam. This steam is then directed at the surfaces to be cleaned, effectively blasting away dirt while sanitizing the air conditioner. 

Advantages of  Aircon Steam Cleaning

  • Eco-Friendly: Steam cleaning generally only uses water to clean the air conditioner, making it safe for both the environment and your health since no chemicals are involved.
  • Effective for Allergen Removal: The high heat from steam cleaning can kill most allergens and pathogens, improving the air quality in your home.
  • No Residue After Cleaning: Since no chemicals are used, there will be no leftover residue —ensuring that nothing harmful circulates through the air you breathe.

Disadvantages of Aircon Steam Cleaning

  • Less Effective on Stubborn Build-ups: While steam cleaning works well for regular maintenance, it may not be as effective at removing stubborn build-ups, such as hardened grease or deep-seated dirt.

Aircon Steam Cleaning vs. Chemical Wash: Which Is Better?

Choosing between steam cleaning and chemical washing will depend on various factors, including the condition of the air conditioner, your preferences, and the specific cleaning requirements.

But it’s important to keep in mind that a chemical wash can be a better option, especially if your air conditioner is heavily soiled and needs a thorough tune-up. This method not only removes stubborn dirt and grime but also enhances the unit’s efficiency and prolongs its lifespan, making it a more reliable choice for long-term maintenance. 

Additionally, chemical wash for aircon can also help tackle deeper issues like mold and bacteria build-up, which steam cleaning may not fully address.

When to Choose Steam Cleaning Chemical Wash
Routine Maintenance Ideal for regular upkeep to maintain efficiency and improve indoor air quality. Best for units that haven't been cleaned for a long time or are heavily soiled.
Mold Issues Suitable only for minor mold problems. Very effective for extensive mold and bacterial growth that steam may not fully eliminate.
Health Concerns Great for those with chemical sensitivities or allergies. Not recommended if you want to avoid chemicals, though highly effective for thorough cleaning.
Restoring Efficiency Maintains general efficiency with regular use but might not be effective for serious build-ups. Can significantly improve performance if the air conditioner has lost efficiency due to severe dirt and grime.

To conclude, steam cleaning is an ideal option for regular maintenance and those sensitive to chemicals, while the chemical wash is better suited for tackling heavy dirt and restoring efficiency. Thus, hopefully, you will already get an idea of what a better option is for your air conditioner needs.
