DIY Aircon Cleaning vs Professional Service

Introduction

Whether your air conditioner is not cooling properly, emitting strange odours, or becoming louder than usual, it may be time for a thorough cleaning. But the real question is: should you do it yourself or hire a professional?

At Cool & Clean, many of our customers arrive unsure whether a quick DIY clean is enough, or if professional servicing is truly worth the investment. In this guide, we’ll walk you through the advantages and disadvantages of both methods—so you can decide what’s best for your comfort and your unit’s health.

What Does Aircon Cleaning Involve?

Before we compare the two methods, it’s essential to understand what proper aircon cleaning entails:

• Washing or replacing filters

• Cleaning evaporator and condenser coils

• Flushing the drainage pipe

• Servicing fans and blowers

• Checking refrigerant levels (professionals only)

• Inspecting overall system performance

Skipping any of these steps can significantly affect your aircon’s efficiency and lifespan.

DIY Aircon Cleaning

Advantages of DIY Cleaning

Cost-Effective

The most apparent benefit is saving money. You can use everyday tools and a bit of basic knowledge to clean external parts and filters.

Quick Fix

If your aircon only needs light maintenance—like unclogging dusty filters—a DIY clean can serve as a temporary solution.

Convenient Timing

You can perform the cleaning at your own convenience without needing to wait for an appointment or technician.

Drawbacks of DIY Cleaning

Limited Access to Internal Components

Most homeowners only manage to clean filters and outer vents. Critical internal components—like coils, blowers, and drainage pipes—remain untouched.

Risk of Damage

Without the correct tools or training, you could unintentionally bend sensitive fins, oversaturate electrical parts, or reassemble components improperly.

No Deep Cleaning

DIY surface cleaning won’t eliminate hidden mould, bacteria, or deeply embedded dust. This often leads to recurring odours and poor performance.

Professional Aircon Cleaning Service

Advantages of Professional Cleaning

Thorough and Safe

Professionals are trained to clean the entire unit safely and effectively, including coils, blowers, and drainage systems.

Enhances Efficiency

A professionally cleaned unit operates more smoothly, cools faster, and consumes less energy—helping reduce your electricity bills.

Increases Lifespan

Preventive servicing helps minimise wear and tear, allowing your aircon to last longer and avoid unexpected breakdowns.

Removal of Mould and Bacteria

Professionals use high-grade tools and antibacterial solutions to eliminate bacteria, fungi, and hidden mould build-up.

Includes Performance Checks

Technicians can identify refrigerant leaks, strange noises, and malfunctioning components—issues that typically go unnoticed in DIY cleaning.

Disadvantages of Professional Cleaning

Expense

Professional servicing costs more upfront compared to DIY, but it often pays off in long-term savings and unit longevity.

Appointment Required

You’ll need to schedule a visit, which might take a few days depending on availability and demand.

When to Use DIY Cleaning

DIY aircon cleaning may be suitable if:

• Your filters are simply dusty

• You want a light clean between professional services

• You’re confident in doing minor household maintenance

• You need a quick fix to improve airflow

However, it’s important to note that DIY cleaning should never replace scheduled professional servicing.

When to Hire a Professional

Professional servicing is strongly recommended when:

• Your aircon emits unpleasant odours or leaks water

• Cooling is uneven or inadequate

• There is visible mould, dust build-up, or insect infestation

• The unit hasn’t been serviced in over 6 months

• You want to maintain the product’s warranty

Most air conditioner manufacturers require certified servicing to uphold warranty conditions.

How Often Should Your Aircon Be Professionally Cleaned?

In Singapore’s warm and humid climate, we recommend:

• Every 3 months for standard residential units

• Monthly or bi-monthly for commercial systems or frequent use

• Additional servicing before high-demand seasons like summer or festive holidays

Conclusion

Both DIY and professional aircon cleaning have their place. A quick DIY clean can help maintain surface cleanliness, but nothing matches the benefits of a thorough, expert clean.

At Cool & Clean, we offer affordable, professional aircon servicing across Singapore—ensuring your unit remains fresh, powerful, and energy-efficient all year round.
