Aircon Chemical Wash vs General servicing Vs Chemical Overhaul

Regular air conditioning maintenance is essential for every home and office in Singapore. With our hot and humid climate, aircons work overtime, making proper care even more important. Many customers often ask: What is the difference between aircon general servicing, aircon chemical wash, and aircon chemical overhaul?
In this guide, LetsCool Aircon and Services Singapore — one of the best aircon servicing Singapore companies — explains each method so you can choose the right service for issues like aircon not cold, aircon water leakaging, aircon light blinking, or recurring aircon error code alerts.

What Is Normal Aircon Servicing? (Routine Care for Smooth Performance)

Normal servicing, also known as aircon general servicing, is the basic maintenance your unit needs every 3–4 months to keep it running efficiently. This service is ideal for households and offices that want to prevent sudden breakdowns, reduce energy bills, and maintain clean airflow.

What Normal Servicing Includes

• Cleaning of air filters
  
  

• Vacuuming of drainage pipe to prevent clogging
  
  

• Removing dust buildup on evaporator and blower
  
  

• Checking overall system condition
  
  

• Inspecting thermostat and operational controls
  
  

Routine servicing helps prevent common issues like aircon not cold, mild aircon water leakaging, and minor airflow problems. It also ensures smoother operation, extending the lifespan of your unit.

Who Should Choose This Service?

If your unit is functioning normally but just needs regular upkeep, general servicing is sufficient. It’s also recommended for customers on an aircon service contract looking for cost-efficient, long-term maintenance. LetsCool Aircon and Services Singapore offers affordable packages that include filter cleaning, drainage flushing, and general system checks — perfect for families and businesses.

What Is Aircon Chemical Wash? (Deep Cleaning for Better Cooling)

A step above routine servicing, the aircon chemical wash is designed for units that are dirty internally or showing moderate performance issues. It uses chemical solutions to remove stubborn dirt, slimy buildup, and mold.

When Do You Need a Chemical Wash?

Choose this service if you face problems such as:

• Aircon blowing warm air or aircon not cold
  
  

• Foul smell when the unit is running
  
  

• Weak airflow
  
  

• Frequent aircon light blinking
  
  

• Drainage clog leading to aircon water leakaging
  
  

What Aircon Chemical Wash Includes

• Dismantling the front cover and components
  
  

• Cleaning the coil with a safe chemical solution
  
  

• Washing blower wheel and drain pan
  
  

• Clearing blockages in the drainage pipe
  
  

• Checking for early signs of component wear
  
  

Chemical washing eliminates mold and bacteria effectively — a major cause of indoor allergies. For homes with pets, young children, or heavy aircon usage, this service is especially beneficial.

Additional Services Often Paired With Chemical Wash

• Aircon gas top up (if cooling is weak due to low refrigerant)
  
  

• Aircon steam wash for coil sanitization
  
  

• Replacement of aircon spare parts when necessary
  
  

As one of the best aircon servicing Singapore companies, LetsCool Aircon and Services Singapore provides both standard and premium chemical wash packages designed for long-lasting cooling performance.

What Is Aircon Chemical Overhaul? (Full Restoration for Poorly Performing Units)

An aircon chemical overhaul is the most intensive maintenance service available. Unlike a chemical wash, which cleans components while still attached to the unit, an overhaul involves complete dismantling for detailed cleaning, repair, and restoration.

This service is ideal if your aircon has serious issues that basic servicing cannot fix.

When Do You Need a Chemical Overhaul?

You should consider an overhaul if you notice:

• Strong aircon error code warnings
  
  

• Persistent aircon not cold even after servicing
  
  

• Severe aircon water leakaging
  
  

• Heavy ice formation on coils
  
  

• Very dirty internal components
  
  

• Unit frequently breaking down
  
  

• Loud or unusual noises
  
  

Overhauls are also recommended for older aircon units or those that have not been maintained for more than 1–2 years.

What Chemical Overhaul Includes

• Full dismantling of indoor unit
  
  

• Complete chemical treatment of coil, blower, and fan
  
  

• Deep cleaning of drainage system
  
  

• Thorough check of aircon compressor servicing needs
  
  

• Lubrication of moving parts
  
  

• Repair or replacement of worn-out aircon spare parts
  
  

• Tightening electrical connections
  
  

• Reinstalling and testing the entire system
  
  

This process restores your aircon to near-new performance, improves cooling, and significantly extends the lifespan of your system.
