In Singapore's humid climate, regular aircon maintenance is essential. For 2026, general servicing costs $20–$70 per unit, while aircon chemical wash ranges from $70–$150 per unit, depending on unit type and quantity[1][2][3][5].

What is General Aircon Servicing?

General servicing, also called basic cleaning, maintains your aircon's daily performance. It includes cleaning or replacing filters, wiping exteriors, clearing drains, and checking refrigerant levels[5].

This surface-level clean suits routine upkeep every 3-4 months, ideal for Singapore's hot weather. Costs start at $20 for one non-inverter unit, rising to $30–$70 for inverters[5]. Multi-unit HDB flats see discounts: $40 for two units, $60 for three[5].

Insider tip: In crowded HDB estates like Punggol or Sengkang, book early mornings to avoid peak heat affecting technicians.

What is Aircon Chemical Wash?

Aircon chemical wash, or deep clean aircon, uses eco-friendly chemicals to remove mould, bacteria, and grime from internal coils, blowers, and drain pans[2][3][8]. It's more thorough than general servicing, targeting stubborn buildup.

Expect disassembly for some units, improving cooling by up to 30% and air quality[2]. Recommended every 6-12 months or after 6 months without service[8]. For 2026 Singapore prices: $70–$90 for one fan coil unit (FCU), dropping to $60+ for multiples[2][4]. Inverter units cost $90–$150[5].

Chemical overhaul, a premium option, fully disassembles for $130–$250 per unit, best for neglected systems[2][5]. Homejourney's vetted pros handle this safely, with 90-day warranties[8].

Aircon Chemical Wash vs General Servicing: Key Cost Comparison 2026

Choose based on your aircon's condition. General servicing prevents issues cheaply; chemical wash fixes deeper problems.

Feature	General Servicing	Chemical Wash
Cost per Unit (1 FCU)	$20–$70[1][5]	$70–$150[2][3][4]
Scope	Filters, exterior, drains[5]	Coils, blower, internals[2]
Frequency	Every 3-4 months[5]	Every 6-12 months[2]
Best For	Routine maintenance	Mould, poor cooling[3]

Packages for multiples reduce costs: 3 units general at $60 total, chemical at $170–$220[2][5]. Long-term, chemical wash saves on repairs by extending lifespan[3].

Singapore-Specific Pricing Factors for 2026

Prices vary by unit type: non-inverter cheaper than inverters[5]. HDB flats (common 2-4 FCUs) average $80–$200 for chemical wash; condos with cassettes hit $100–$250[5]. BCA-registered pros charge fairly[1].

Seasonal hikes during March-June heatwaves add 10-20%. Condo MCST rules may require approvals for overhauls. Gas top-up extras: $100–$150 if low[4].

HDB Tip: Ground-floor units need more frequent chemical cleans due to dust.
Condo Tip: High-floor inverters cost more but efficiency gains offset in large spaces.

Signs You Need Chemical Wash Over General Servicing

Don't wait for breakdowns. Act on these Singapore homeowner signals:

Weak cooling despite low thermostat.
Water leaks or musty smells (mould in humidity).
Noisy operation or high electricity bills.
Bad odours post-rainy season.

General servicing suffices for light dust; opt for AC wash Singapore if uncleaned over 6 months[8]. Test: Run at 16°C—if not cold in 10 mins, book chemical[3].
