Singapore Aircon Cleaning Price Guide 2025: Costs & Services Explained

Introduction

In Singapore’s tropical climate, where heat and humidity reign all year, air conditioning is more than a luxury—it is a necessity. Whether you live in an HDB flat, condominium, or landed property, keeping your air conditioner in good condition is essential. But with so many service providers around, residents often ask the same practical question: How much does aircon cleaning cost in 2025?

This guide provides a detailed breakdown of aircon cleaning prices in Singapore, including the different service types, what affects pricing, and how often you should maintain your unit to get the best value for your money.

Singapore Context: Usage and Maintenance

Aircon usage in Singapore is among the highest in Asia. Most households run their units almost daily, with average usage between 6 to 10 hours per day. This heavy reliance means aircon units collect dust, dirt, and moisture quickly—prime conditions for mould growth.

HDB Flats: Compact layouts mean rooms heat up quickly, making cooling systems work harder.
Condominiums: Multi-split systems are common, requiring periodic servicing across multiple indoor units.
Landed Properties: Larger systems with higher capacity need more frequent cleaning due to extended run times.

In all cases, timely aircon servicing not only improves comfort but also prevents high repair costs later.

Why Regular Aircon Cleaning Matters

Health Protection – Prevents mould, dust mites, and bacteria from circulating indoors.
Energy Efficiency – Clean coils and filters improve cooling efficiency, lowering electricity bills.
Extended Lifespan – Regular cleaning reduces wear and tear on compressors and motors.
Cost Savings – Avoids expensive breakdowns by catching issues early.

Skipping regular maintenance can double long-term costs because repairs like gas top-ups or compressor replacements are far more expensive than routine cleaning.

Types of Aircon Cleaning Services & 2025 Price Ranges

1. General Aircon Cleaning

Price (2025): $25–$40 per unit (more affordable with multi-unit packages)
What’s Included: Cleaning of air filters, front panel, and outer casing; basic check of system functionality.
Best For: Monthly to quarterly maintenance for light users.

2. Chemical Wash

Price (2025): $60–$90 per unit
What’s Included: Chemical cleaning of the fan coil unit, blower wheel, and drainage pipe.
Best For: Units with moderate dust buildup, clogged drainage, or weak cooling.

3. Chemical Overhaul

Price (2025): $120–$180 per unit
What’s Included: Complete dismantling of the indoor unit, thorough chemical wash of all components, deep cleaning of evaporator coils, and drainage system.
Best For: Heavily clogged units, major mould growth, or aircons not serviced for over a year.

4. Gas Top-Up

Price (2025): $60–$120 depending on refrigerant type (R22 vs R410A/R32)
What’s Included: Refilling refrigerant gas to restore cooling efficiency.
Best For: Aircon units blowing warm air due to gas leaks or long-term usage.

Step-by-Step: What Happens During Professional Cleaning

A typical professional servicing includes:

Powering down the system and safety preparation.
Removing and washing air filters.
Cleaning evaporator coils and blower wheel.
Flushing drainage pipes to prevent water leakage.
Vacuuming or wiping exterior panels.
Running performance tests (temperature, pressure, and noise levels).

For chemical wash or overhaul, technicians will disassemble the unit and use specialized solutions to dissolve grime and mould buildup.

DIY vs Professional Cleaning

While it is possible to clean air filters at home, professional servicing provides a much deeper clean. DIY efforts often miss the coils, blower, and drainage system where most mould and bacteria accumulate.

DIY Cleaning: Good for weekly or bi-weekly filter washing.
Professional Cleaning: Necessary every 3–4 months for heavy-use households in Singapore.

Signs Your Aircon Needs Immediate Cleaning

Weak or uneven cooling.
Foul, mouldy odours.
Water leakage from the indoor unit.
Unusual noises during operation.
Higher-than-normal electricity bills.

These symptoms often mean the aircon is overdue for servicing and may require more than just general cleaning.

Health Benefits of Regular Aircon Cleaning

Reduces allergens and prevents respiratory problems.
Eliminates mould spores from spreading indoors.
Improves sleep quality by maintaining steady airflow and cooling.
Protects children and elderly from bacteria-borne illnesses.

Clean air equals healthier living—something especially critical in Singapore’s dense urban environment.

Cost & Frequency of Servicing in Singapore (2025)

General Cleaning: Every 2–3 months, especially for daily users.
Chemical Wash: Once or twice a year depending on condition.
Chemical Overhaul: Every 12–18 months for older or heavily used units.
Gas Top-Up: Only when required due to leakage or reduced cooling.

Estimated Annual Costs (per household with 3–4 units):

Light Usage: $250–$400
Heavy Usage: $400–$700
