Average Cost of Aircon Servicing in Singapore (HDB, Condo, Landed)

Introduction

In Singapore’s hot and humid climate, air conditioning is less a luxury and more a quiet necessity. Whether you live in a compact HDB flat, a high-rise condo, or a sprawling landed home, your aircon works hard—cooling, dehumidifying, and filtering the air daily. But keeping it efficient doesn’t happen on its own. Regular servicing is what separates a comfortable living space from one filled with weak airflow, high electricity bills, or surprise breakdowns.

Still, one common question remains: how much should aircon servicing actually cost in Singapore? Prices vary based on housing type, number of units, and service depth, but understanding the typical ranges helps homeowners plan smarter.

This guide breaks down average servicing costs for different property types—HDB, condo, and landed—and explains what goes into those prices, so you can make sense of every quote before you book.

Singapore Context: Different Homes, Different Cooling Needs

Aircon usage patterns in Singapore reflect our housing diversity. Each property type carries its own servicing rhythm and pricing logic.

HDB Flats

HDBs tend to have 2–4 aircon units, mostly wall-mounted split systems for bedrooms and sometimes the living room. Servicing costs here stay on the lower end due to easier access and simpler piping layouts.

Average frequency: every 3–4 months.
Key concern: dust build-up and mould from humidity in smaller enclosed rooms.

Condominiums

Condo residents often use multi-split inverter systems with concealed piping and ceiling units. These are efficient but more complex to clean, especially in units with false ceilings or longer piping runs.

Average frequency: every 3 months (to maintain cooling efficiency and prevent odours).
Key concern: drainage issues from condensate build-up, and uneven cooling in rooms.

Landed Properties

Landed homes, especially multi-storey ones, usually feature large-capacity or ducted systems covering wider areas. Servicing these requires more manpower, longer ladders, and sometimes special access for rooftop compressors.

Average frequency: every 2–3 months, especially for families using aircon throughout the day.
Key concern: system pressure balance and compressor maintenance due to heavier load.

Why Regular Aircon Cleaning Matters

Servicing isn’t just cosmetic—it directly affects comfort, efficiency, and lifespan. A poorly maintained system consumes up to 30% more electricity and delivers noticeably weaker cooling.

Benefits of routine cleaning:

  • Prevents water leaks from clogged drainage pipes
  • Removes mould, bacteria, and allergens from filters and coils
  • Reduces energy bills by improving heat exchange efficiency
  • Prolongs compressor life (the costliest component)
  • Keeps the air fresh and odour-free

In a city where humidity hovers around 80%, skipping service for even six months can mean visible mould in the air vents and reduced air quality.

Types of Aircon Services and What They Include

Not all servicing sessions are equal. Here’s a breakdown of the main service types and how they affect pricing.

Service TypeWhat It IncludesTypical Use CaseAverage Cost (per unit)
General CleaningFilter washing, coil vacuuming, drainage flushingRoutine maintenance$25–$40
Chemical WashDeep cleaning using mild chemicals for coil and blowerWeak cooling, mild odour issues$60–$90
Chemical OverhaulFull dismantling, chemical cleaning of all componentsMajor performance drop, dirty system$120–$180
Gas Top-UpRefilling refrigerant gas (R22 or R410A)Low cooling or leakage$40–$150

Each service type builds on the other, with chemical overhauls and gas refills priced higher due to labour time and material cost.

Step-by-Step: How a Professional Aircon Servicing Works

A proper aircon cleaning isn’t just a quick wipe and go. Professional teams follow a careful, multi-step process:

  1. System Inspection – Technicians check fan coil condition, pressure levels, and drainage.
  2. Filter and Cover Removal – Dust and grime are washed off using mild detergent.
  3. Evaporator Coil Cleaning – A soft brush or chemical solution is applied to remove build-up.
  4. Vacuuming and Drainage Flush – Prevents leaks by ensuring condensate lines are clear.
  5. Compressor & Pressure Check – Outdoor unit is tested for pressure stability.
  6. Function Test – System is reassembled, tested for cooling consistency and airflow.

For larger homes, the process may take half a day. For smaller HDB units, an experienced team can service three units in under two hours.

DIY vs Professional Aircon Cleaning

While homeowners can handle simple filter cleaning monthly, full system servicing is best left to professionals. Here’s why:

AspectDIYProfessional
Tools & EquipmentBasic (vacuum, cloth)High-pressure cleaners, coil chemicals
SafetyRisk of damaging fins or wiringTrained for safe disassembly
Depth of CleaningSurface-level onlyFull internal cleaning
CostFree (just your time)$25–$90 per unit
ResultTemporaryLong-lasting performance

DIY works for quick refreshes, but without full drainage flushing or coil treatment, bacteria and mould often return quickly.

Signs Your Aircon Needs Immediate Servicing

You don’t always need a reminder on the calendar. Watch for these signs:

  • Weak airflow even at high fan settings
  • Water dripping from the indoor unit
  • Unusual odours (musty or chemical smells)
  • Loud rattling or buzzing sounds
  • Higher electricity bills with no change in usage
  • Intermittent cooling (cold air stops mid-cycle)

If these appear, schedule a chemical wash or overhaul before the system’s performance declines further.

Health Benefits of Regular Servicing

Singapore’s warm, enclosed indoor environments are perfect breeding grounds for mould spores, dust mites, and bacteria. Regular servicing keeps indoor air cleaner and reduces respiratory irritants, especially important for households with:

  • Young children or elderly members
  • Asthma or sinus-prone individuals
  • Pets shedding hair and dander

Clean air conditioning also reduces odours, prevents mildew, and improves sleep quality—a subtle but noticeable gain after each cleaning.

Cost & Frequency in Singapore: HDB vs Condo vs Landed

Now for the practical question—how much does it cost? Prices differ not only by number of units but also by accessibility, piping complexity, and service type.

1. HDB Flats

  • General servicing: $60–$80 (2 units), $90–$120 (3–4 units)
  • Chemical wash: $80–$150 (1–2 units)
  • Overhaul: $150–$200 per unit
  • Gas top-up: $50–$120 depending on gas type

Most households opt for quarterly packages, saving about 10–15% compared to one-time calls.

2. Condominiums

  • General servicing: $90–$130 (2–3 units), $140–$180 (4 units)
  • Chemical wash: $100–$180 per unit
  • Overhaul: $160–$220 per unit
  • Gas top-up: $80–$150

Condo systems often require extra care due to concealed pipes or ceiling cassettes. Many owners sign bi-monthly contracts to maintain efficiency.

3. Landed Properties

  • General servicing: $120–$180 (up to 4 units), $200–$300 (6+ units)
  • Chemical wash: $120–$200 per unit
  • Overhaul: $180–$250 per unit
  • Gas top-up: $100–$180

Servicing large homes takes longer due to multiple compressors and extended piping. Technicians also factor in travel and ladder access costs.

Typical overall range:

For most Singapore homes, expect $25–$50 per unit for standard servicing, and up to $180 per unit for deep chemical overhauls.

Package Deals and Promotions

Many service providers offer value packages. For instance:

Package TypeUnits CoveredFrequencyAverage Cost
