Aircon Servicing in Singapore: What's the Landlord's Responsibility vs. the Tenant's?

Aircon is not a luxury in Singapore — it's a necessity. In a climate that hovers between 25°C and 34°C year-round with high humidity, aircon runs almost constantly in most homes. This makes maintenance a significant cost and a frequent source of landlord-tenant disputes.

Here's a clear breakdown of who is responsible for what.

The Standard Split (What Most Leases Say)

Most Singapore Tenancy Agreements follow this division:

The key principle: Tenants maintain the units through regular servicing; landlords are responsible for the underlying condition of the equipment.

Types of Aircon Services — What You're Actually Paying For

General Servicing ($25–$40 per unit)

The basic quarterly clean: technician removes and cleans the air filters, cleans the evaporator coil, checks the drainage tray, tests the unit, and sometimes does a quick check of the refrigerant level.

Most TAs require this at least 4 times a year (every 3 months). Some require every 2 months. This is the tenant's standard obligation.

Chemical Wash ($80–$120 per unit)

A deeper clean where the unit is partially disassembled, the coil is cleaned with chemical agents, the fan barrel is cleaned, and drainage pipes are flushed. Typically done annually or when units are not cooling well despite regular servicing.

Responsibility for chemical washes varies by lease — some TAs make it the tenant's, others the landlord's. Read yours carefully.

Chemical Overhaul / Full Dismantle ($150–$250 per unit)

The unit is fully dismantled, all components cleaned individually, and reassembled. Done when a unit is heavily fouled or after several years of intensive use.

This is almost always the landlord's responsibility unless specifically assigned to the tenant.

Gas Top-Up / Refrigerant Refill ($80–$200)

If the aircon is not cooling effectively, it may be low on refrigerant. If the refrigerant is low due to normal depletion over time, the landlord should pay. If it's low because of a pipe leak caused by tenant negligence (e.g., damaging a pipe), the tenant is responsible.

Compressor Replacement ($600–$1,500)

The compressor is the heart of the aircon system. When it fails, it is almost always due to age or a manufacturing defect — not tenant behaviour. This is universally the landlord's cost.

What Happens If Tenants Don't Service?

If a tenant fails to service the aircon as required by the TA and the unit develops a problem (e.g., water leaking into the ceiling, mould on the coil), the landlord can:

1. Deduct repair costs from the security deposit
2. Claim damages if costs exceed the deposit

Critically, aircon service records are increasingly requested by landlords on move-out. If you can't produce receipts from a professional company, you may lose part of your deposit.

Always keep your aircon servicing receipts (photos or PDFs) throughout your tenancy.

Brands and What to Expect in Singapore

Singapore homes predominantly use:

• Daikin — most popular, known for reliability; local parts widely available
• Mitsubishi Electric — premium, energy-efficient Starmex series
• Mitsubishi Heavy Industries (MHI) — robust, common in older buildings
• Panasonic — good mid-range option with inverter technology
• LG / Samsung — growing share, strong smart features

Older R22 gas systems (pre-2015 buildings) are being phased out. If your unit uses R22, ask the landlord when they plan to upgrade — R22 is more expensive and harder to source. Newer systems use R32 or R410A.

How to Book Aircon Servicing in Singapore

For a standard 3-unit HDB (1 living room + 2 bedrooms), a general service session costs approximately $80–$120 for all 3 units booked together (individual unit prices are $25–$40).

When booking, have ready:

• Number and type of units (wall-mounted, cassette)
• Brands
• Approximate size/BTU if known
• Preferred date and time slot (morning 9am–12pm, afternoon 12pm–3pm)

You can request quotes through SGLinkUp's Services tab — specify the service type, brand, and number of units for an accurate quote.

If Your Aircon Breaks Down

1. Do not attempt repairs yourself — this voids warranties and may worsen the issue
2. Contact a licensed aircon company for a diagnostic inspection (usually $50–$80)
3. Notify your landlord in writing (WhatsApp message with timestamp is fine)
4. The landlord must arrange and pay for repairs to components they're responsible for within a reasonable time (in Singapore, 7–14 days is generally considered reasonable unless it's an emergency)
5. If the landlord is unresponsive, you can arrange repairs yourself and deduct the cost from rent — but document everything carefully

Practical Tips for Tenants

• Book a servicing contract (quarterly, bi-annual) rather than one-off visits — it's cheaper and ensures you don't forget
• Clean filters yourself monthly — this takes 10 minutes and significantly reduces the workload (and risk of leaks) between professional visits
• Set temperature to 24–25°C — not 16–18°C. Lower temperatures don't cool the room faster; they just waste electricity and strain the compressor
• Run fan mode overnight — sufficient cooling, far lower power consumption
• Watch for water dripping from indoor units — this often means a blocked drainage pipe and should be addressed immediately before it causes ceiling or wall damage
