Aircon Chemical Wash VS Chemical Overhaul Which One  2524521872

Aircon Chemical Wash VS Chemical Overhaul, Which One?

Your air conditioner works hard to keep you cool, especially in Singapore’s heat. Yet, deciding on its maintenance can be confusing. Should you go for a chemical wash or a full chemical overhaul? This choice affects your unit’s efficiency and lifespan.

A chemical wash involves using a solvent to clean critical parts of your air conditioner like fan coils and filters. It clears minor blockages and mould, improving indoor air quality.

Think of it as routine service to keep things running smoothly.

On the other hand, an overhaul is more invasive but thorough. It’s needed when your AC has significant issues – loud noises or inefficient cooling are signs. Technicians dismantle the entire system, check each part for damage, clean them with chemicals, and replace if necessary.

The distinction matters: Chemical wash is preventive; overhaul is corrective.

We aim to clear the fog surrounding these services so you know exactly what your aircon needs. Stay tuned – making this decision could save you time and money while ensuring optimal performance from your unit.

Key Takeaways

  • A chemical wash cleans major parts of your air conditioner, like fan coils and filters. It’s less costly at £70 per unit and best for minor issues.
  • Overhauls are more in – depth, fixing big problems by cleaning every part. This costs £100 per unit but can make your aircon work like new.
  • Billy Aircon suggests getting a chemical wash twice a year and an overhaul every 3 to 5 years to keep your air conditioner running well.
  • Choose a chemical wash if your aircon needs minor cleaning. Pick an overhaul for serious issues or if it hasn’t been cleaned in years.
  • Always ask experts from places like Billy Aircon what is best for your unit. They know how to check and fix your air conditioner right.

What is Aircon Chemical Wash?

Aircon chemical wash is a deep clean for your air conditioning system. Technicians take apart key parts like fan coils, water trays, and air filters. They use a special chemical solution to get rid of dirt, mold, and bacteria.

This method makes sure your unit works well and cools better. It also keeps the air in your home cleaner.

This service needs doing twice a year. For one unit, it costs £70; if you have more than one, each costs £60. Billy Aircon provides this service across Singapore, helping keep homes cool and air quality high.

They ensure every part of the air conditioner gets cleaned properly without any damage.

What is Aircon Chemical Overhaul?

A chemical overhaul is like giving your air conditioning unit a full spa treatment, but in Singapore. Billy Aircon experts take everything apart and clean each piece with special care.

They get rid of all the dirt and harmful stuff sticking inside, such as toxic gunk that blocks vents or damages evaporator coils. This process also finds parts that are tired or broken—like fan bearings or air filters—and fixes them or puts in new ones.

It’s not just wiping things down; it’s checking every corner to make sure your cooling system works great again.

This service costs £100 for one machine, and you should do it every 3 to 5 years. Think of it as a health check-up for your AC, ensuring it runs smoothly without wasting energy on extra effort just to keep cool.

The team at Billy Aircon handles this task with skill from years of experience, making sure nothing gets missed. After an overhaul, your air conditioner will almost feel like new, saving money on bills and avoiding big repairs later on.

Just imagine enjoying cleaner air and consistent cooling without any funny smells—a true refresh for anyone living with the hot Singapore weather.

Key Differences Between Chemical Wash and Overhaul

Key differences hinge on how deep the cleaning goes, how much of your aircon gets taken apart, how much you’ll pay, and whether your unit needs a quick refresh or a more thorough fix.

A chemical wash removes dirt from major parts without taking everything apart—great for units needing minor attention. An overhaul involves dismantling nearly all parts for a comprehensive clean—best for systems showing signs of serious trouble.

Costs vary; overhauls are pricier but tackle deeper issues like blockage in vents or drain pipes, ensuring your system runs smoothly.

At Billy Aircon, we’ve seen it all—from slightly dusty units that just need a bit of care to ones caked in grime that haven’t been serviced in years. Our team jumps into action with either service depending on what’s needed: swift chemical washes for regular maintenance or full overhauls when things look grim inside those air ducts and around the condenser coil.

Choosing between these options means weighing up what your system can

Pros and Cons of Aircon Chemical Wash

Opting for an aircon chemical wash boosts your unit’s efficiency. It makes your home cooler and fresher. Here are the pros and cons:


  1. Improves Cooling Efficiency: A chemical wash removes dirt and grime from your aircon parts, like the fan coil and filters, enhancing cooling performance.
  2. Extends Lifespan: Keeping internals clean reduces wear, prolonging your unit’s life.
  3. Enhances Indoor Air Quality: Cleaner aircon parts mean cleaner air in your space.
  4. Cost-Effective Maintenance: At £70 for one unit, it’s a budget-friendly option to maintain peak performance.


  1. Surface-Level Cleaning: This method might not reach deeper mechanical issues lurking inside.
  2. Short-term Solution: While effective initially, it may not prevent long-term degradation due to hidden problems.
  3. Limited Blockage Removal: May not fully clear blockages in drain pipes or vents, leading to potential water leaks or reduced efficiency over time.
  4. No Comprehensive Check-Up: Does not include a thorough inspection of electrical components and connections which might be failing unnoticed.

In situations where your air conditioner isn’t cooling as well as before but isn’t showing major signs of failure, a chemical wash is ideal. However, if you suspect deep-seated issues or significant wear and tear beyond surface dirt, this option might fall short of fully restoring your unit’s health.

Pros and Cons of Aircon Chemical Overhaul

Aircon chemical overhaul is a big step for your cooling system. It dives deep, fixing more than just surface problems.

  2. Improves air flow, making your room cooler faster.
  3. Stops noises from faulty bearings inside the unit.
  4. Extends your aircon’s life by preventing corrosion and rusting.
  5. Comes with a workmanship warranty, ensuring peace of mind.


  1. Costs £100 per unit, quite a bit higher than a regular wash.
  2. Takes longer, meaning you’ll be without aircon for some time.

This choice brings major benefits like better performance and longer lifespan but asks for more money and patience.

Making the Choice: Chemical Wash or Overhaul
