Enzyme Cleaning An Aircon Unit 

Much like the chemical cleaning process, enzyme cleaning makes use of an enzyme solution instead of a chemical. The process typically takes 60 minutes for 1 fan coil unit. This type of aircon maintenance is recommended over chemical cleaning when a professional aircon servicing company performing the job is not able to unmount to completely overhaul the entire aircon unit. When it comes to chemical cleaning, however, it will do the job as effectively as enzyme cleaning but due to the hazardous nature of alkaline and chemicals, it is not as environmentally friendly as enzymes. For use of chemicals, it is always recommended to unmount the aircon unit so we can use a large amount of water to wash off the chemical for environmental and safety reasons, especially if you have kids or pets at home that could be sensitive or allergic to alkaline/chemical particles.

Let’s take a look at the difference of enzyme cleaning from chemical cleaning and chemical overhaul:

When it comes to aircon servicing, we tend to usually choose what’s best for your aircon unit as it is a vital component to be able to perform as its best. In case your aircon unit is very dirty there can be so many methods which you can use in cleaning or maintaining it. Here are some of the best 3 methods for intensive and deep cleaning an aircon unit as recommended by professional aircon servicing companies:

1) Chemical cleaning: This type of cleaning method takes about 60 minutes and is suitable for moderately contaminated aircon coils but it can be slightly harmful to your coil after a certain amount of time.

2) Chemical overhaul: This type of cleaning method takes about 60 minutes and is recommended as an effective method for use in comprehensive contaminated coils.

3) Enzyme cleaning: This type of cleaning method takes about 60 minutes and is recommended as a safe and environmentally friendly method, especially for moderately contaminated fan coils.

Pro 338 Reminder: A fan-coil unit requires one hour to get cleaned. Therefore, a professional aircon servicing company considers enzyme cleaning as the ideal alternative to chemical cleaning in all situations when we can’t unmount the unit to clean it.

How to choose among these types of aircon unit cleaning method?

Aircon unit enzyme cleaning is a much more natural way to clean your aircon unit. It’s less harsh and has no harmful chemicals that can get into the environment, making it great for those who want to be environmentally conscious. If you just don’t like the idea of using chemicals around your family, then an enzyme cleaning service is a good option. You can also call and ask for recommendations from your trusted professional aircon servicing company when it comes to aircon servicing and aircon maintenance.

How does enzyme cleaning exactly work for an aircon unit?

When you hear the word enzymes, it sounds like some sort of miracle chemical developed in a lab. In fact, enzymes are a natural part of our world and play an important role in everyday life. They are found in every living organism and life is not possible without enzymes. Enzymes are catalysts and not living organisms. They cause natural reactions to occur faster. Enzymes either start a process or accelerate an existing process. Whenever a substance needs to be removed or transformed into another substance, enzymes are the answer. They even play an important role in our own bodies. Enzymes we produce in our body, for instance, help digest food, which is then converted into the energy we need.

The process is similar to regular chemical cleaning, but it relies on enzyme solutions instead of chemicals to clean. There are three types of enzymes: protease (breaks down protein), lipase (breaks down fat), and amylase (breaks down starch). These enzymes will break down any organic material in your aircon unit so that you don’t have to scrub or use harsh chemicals like bleach or ammonia. Enzymes are an effective and all-natural way of achieving your specific target of cleaning. Enzymes are environmentally friendly, therefore they can assist in the cleaning of toxic substances from your aircon unit.

Enzyme+36 for aircon unit fan coil cleaning:

Enzyme+36 is a nonrinse solution guaranteed to remove the restriction of airflow caused by organic bio-film and microbial growth no matter how impacted.  Enzyme+36 was specifically engineered for aircon unit fan coils. The plus36 immediately damages the cells of microbial planktonic and biofilms, stopping the formation and adhesion as the enzymes start their digestion process to eradicate the organic biofilms and microbial organisms. Enzyme+36 is completely saturated and coats the coil and continues to protect for a long time.

An aircon unit fan coil will perform at its highest designed efficiency level when it’s first installed. Over a short period of time, it loses its efficiency due to poor filtration programs and most of all improper cleaning methods.  Traditional coil cleaning methods only clean the surface and 2-3 inches within the coil.  This is a major problem for thick coils 6 inches and above. Enzyme+36 nonrinse solution is guaranteed to remove bio-film and microbial growth from any depth of the fan coil unit no matter how plugged it is.  Enzyme+36 was engineered to immediately destroy and digest bio-film and microbial organic organisms that grow within coils. 

Benefits of Enzyme+36 for an aircon unit fan coil:

Pro 338 Reminder: As much as possible, do not attempt to perform a DIY method when it comes to cleaning or maintaining complicated or hard-to-reach parts of an aircon unit. A professional aircon servicing company will always be the better choice since they are trained, skilled, and have the proper tools to perform even the hardest type of aircon servicing

– Removal of organic microbial and biofilm growth within your drainage system, drain pan, blower wheels, and other surfaces of your aircon unit

– Increased heat transfer

– Decreased differential pressure drops across the fan coil

– Lower utility cost
