Comparing Aircon Overhaul and Chemical Cleaning

Keeping your aircon clean and working well is important. This can be done through chemical cleaning or an overhaul. Chemical cleaning involves using chemicals to get rid of moulds and bacteria in parts of the aircon like coils and filters.

An overhaul goes further, fixing and cleaning more parts for better performance. Experts suggest getting your aircon chemically cleaned twice a year to make it last longer and keep the air fresh.

An overhaul costs between $130 to $180 but comes with benefits like follow-up services and a 90-day guarantee on the work done. With over 25 years in the business, Billy Aircon has become skilled at making sure customers are happy by responding quickly, within 24 hours, to any concerns.

Choosing between chemical cleaning or an overhaul depends on how often you use your aircon, how much money you can spend, and what condition your unit is in. Keeping up with regular maintenance stops big problems before they start and keeps everything running smoothly.

Let’s learn more about each method!

Understanding Aircon Chemical Cleaning

Aircon chemical cleaning targets the essential components of your air conditioning unit. Technicians use a special chemical solution to clean coils, air filters, and water trays. This process effectively removes molds and harmful bacteria, ensuring the air blowing through your home is clean and safe.

It’s a preventive maintenance task that helps in improving indoor air quality and enhancing cooling efficiency.

This type of cleaning is ideal for units needing basic maintenance without major repairs. It refreshes the system, preventing common problems like bad smells or poor airflow. Compared to traditional cleaning methods, chemical wash penetrates deeper into hard-to-reach parts of the fan coil and condenser coil.

Users enjoy fresher air and a more efficient machine after this service, making it a popular choice for maintaining an optimal environment at home or work.

The Process of Aircon Overhaul

The process of aircon overhaul is thorough and aims to clean, fix, and ensure the air conditioning system runs smoothly. It requires skilled technicians who know how to handle every part of the unit with care.

  1. Disassemble the Aircon Unit: Technicians start by taking apart the air conditioner to reach every component.
  2. Clean the Coils: They carefully clean the coils, which are crucial for cooling the air. This helps in efficient heat exchange.
  3. Wash Air Filters: Dirty air filters get a thorough wash to remove dust and other particles that block clean air from flowing.
  4. Clear Water Trays and Drainage Pipes: Any water build-up or blockage in trays and pipes is cleared to prevent leaks and damage.
  5. Inspect Heat Exchange Coils: These coils are checked for any signs of wear or damage, ensuring they can effectively regulate temperature.
  6. Clean Blower Wheels: Blower wheels push air through the ducts; cleaning them enhances airflow and quality of air.
  7. Check for Corrosive Damage: All parts are inspected for corrosion since it can lead to serious damage over time.
  8. Fixing Identified Issues: Any problems found during inspection are fixed. This could include sealing leaks or replacing damaged parts.
  9. Reassemble and Test Run: After everything is cleaned and fixed, technicians put the unit back together and run tests to ensure it’s working as it should.

This process is less invasive and requires fewer resources, making it an economical choice for regular maintenance.

On the other hand, an aircon overhaul involves thorough cleaning along with repairs. This service addresses more complex issues within the unit, which contributes to its higher pricing.

Regular use of this cleaning method can keep your air conditioning unit running smoothly.

This type of cleaning is also cost-effective compared to more intensive services. It extends the life of your air conditioner by preventing the buildup of dirt and debris that can cause damage over time.

Benefits of Aircon Overhaul

An aircon overhaul ensures your unit operates smoothly for many years. This thorough cleaning and repair process addresses every component of the system, fixing any issues that could lead to breakdowns.

It’s more than just a simple clean; it deeply rejuvenates the system, enhancing its performance and efficiency.

Regular overhauls can significantly extend the lifespan of your air conditioning unit. They also improve its overall efficiency, ensuring it uses less energy to cool your space. This means you save money on power bills in the long run while enjoying a cooler environment.

With an overhaul, your unit works like new again, providing reliable cooling without unexpected failures.

Making the Choice: Factors to Consider

Choosing between aircon chemical cleaning and overhaul involves weighing several critical considerations unique to your needs. Explore more to find the right solution for your aircon unit.

The Condition of the Aircon Unit

The condition of the aircon unit plays a crucial role in deciding between chemical cleaning and an overhaul. If an aircon struggles with efficiency, emits strange noises, or releases unpleasant odours, it might only need a chemical clean to eliminate moulds and harmful bacteria.

This process can significantly improve its performance by clearing out accumulated dirt and grime without dismantling the entire system.

For units that have been in use for many years without thorough maintenance, an overhaul may be necessary. Overhauling rejuvenates the aircon by deeply cleaning every part and repairing or replacing damaged components.

It ensures the unit remains functional for many more years, enhancing both its condition and longevity. Regular upkeep following either procedure is vital to maintain peak performance and efficiency.

Budgetary Constraints

Understanding the condition of your aircon unit is critical, but so is recognising how much you can afford to spend on its maintenance. Budgetary constraints play a significant role in deciding between chemical cleaning and an overhaul.

Chemical cleaning often comes with a lower price tag compared to a full overhaul. This makes it an attractive option for those looking to save money while still ensuring their aircon unit runs efficiently.

However, if your aircon requires more than just basic cleaning—perhaps it needs fixing or thorough maintenance—an overhaul might be necessary despite the higher cost. Making this choice depends largely on balancing your budget with the needs of your aircon unit.

Carefully consider both options’ pricing information before making a decision that ensures value for money and long-term functionality of your cooling system.

Frequency of Use

The frequency of use plays a crucial role in deciding between aircon chemical cleaning and overhaul. Units used daily need more frequent maintenance to keep them running efficiently and to ensure they last longer.

For high-use environments, such as commercial spaces or hot climates where the air conditioner is essential, considering more regular chemical cleanings can prevent the need for early overhauls.

Homes that use their air conditioners less might not require services as often. However, it’s vital to perform at least the recommended bi-annual chemical cleaning to avoid build-up that can lead to significant issues down the line.

Making an informed decision involves evaluating how often you rely on your air conditioning unit.


Choosing between aircon chemical cleaning and overhaul hinges on your unit’s state, budget, and usage. Chemical cleaning offers a cost-effective solution for routine maintenance. For more comprehensive fixes, an overhaul is advisable.

Understanding the distinctions helps in making informed decisions for long-term aircon health. Consider these factors carefully to ensure your air conditioning system remains efficient and effective.
