How much does aircon servicing cost in Singapore?

Across 19,287 aircon price data points collected on StringsSG since 2018, the most common price for 3 units is $85 to $95 (35% of customers), and 15% pay more than $90.

StringsSG general servicing for 3 units is $73.46 with transport included, and the price per unit keeps falling as you add units to the same visit.

Aircon servicing price per unit

Servicing gets cheaper per unit when several units are done in one visit, because travel, parking and setup are shared. StringsSG general servicing for wall-mounted units:

StringsSG general aircon servicing price per unit by number of units
Units	You pay	Per unit	Excl. $20 transport
1 unit	$47.84	$47.84	$27.84
2 units	$57.41	$28.70	$18.70
3 units	$73.46	$24.49	$17.82
4 units	$89.52	$22.38	$17.38
5 units	$100.97	$20.19	$16.19

Where "from $16 per unit" comes from: most Singapore providers quote a per-unit price and add a transport fee of around $20. Our prices include transport, so the last column sets that fee aside to compare like with like. For 5 units that is $16.19 per unit; the amount you actually pay is $100.97.

Worked example: a 4-room HDB flat with 3 aircons

A typical 4-room HDB flat has 3 wall-mounted units, one in the living room and one in each of two bedrooms. Serviced every 3 months, the yearly cost looks like this:

4 one-time bookings

$293.84

a year, at $73.46 per visit

Save $14.68

Annual package, 4 visits

$279.16

a year, visits scheduled for you

Annual package, 3 visits

$209.37

a year, every 4 months

If one unit starts smelling musty or cooling poorly, add a chemical wash for that unit only ($82.80) rather than washing all three. See the annual servicing package for what each visit covers.

Chemical wash vs chemical overhaul: which should you pay for?

Chemical wash

from $82.80

The unit is partly dismantled and the evaporator coil and water tray are treated with a chemical solution.

Airflow is weak
The unit smells musty
It has not been serviced for a year or more

Chemical overhaul

from $149.04

The fan coil unit comes off the wall so the blower wheel, coil and full drainage line can be cleaned, then it is reassembled and tested.

Cooling is still poor after a recent service
The unit leaks water
It has been unused for months

Neither replaces regular general servicing. See aircon chemical wash and overhaul for what each job includes.

Aircon gas top-up price by refrigerant

Gas top-up prices depend on the refrigerant your unit uses and how much is needed. Typical Singapore prices:

R22

$40 to $100

R410A

$90 to $150

R32

$120 to $220

R32, used in most newer inverter units, costs the most. StringsSG charges $106.72 for a half-tank top-up and $147.20 for a full tank per unit, transport included. Low gas almost always means a leak, so have the leak found and fixed first, or the new gas escapes too. More on aircon gas top-up.

Aircon servicing price statistics and trends

What Singapore customers pay for 3 units

Share of customers by price paid for a one-time general service of 3 units. The most common price is $85 to $95 (35%). 15% pay more than $90, often without comparing all-in prices.

Aircon servicing demand, 2022 to 2026

Demand is highest around July and lowest around January. The July peak has grown from 80 to 115 on our demand index, so book early for mid-year slots.

Average price to service 1 aircon unit in Singapore

The average market price for 1 unit rose from $35 in 2015 to $50 in 2026 (+43%), with higher labour, transport and materials costs. StringsSG's 1-unit price of $47.84 is below the 2026 average.

What affects the price of aircon servicing?

Number of units

The fixed cost of a visit is shared across every unit serviced, so 5 units cost $20.19 each against $47.84 for a single unit. Service them all in one visit.

Type and size of unit

Prices here are for wall-mounted units. Ceiling cassette units take longer to open and clean, so they cost more - see ceiling cassette aircon servicing. Larger units (18,000 BTU and above) can cost more to overhaul.

Condition of the unit

A unit left a year or more without servicing may need a chemical wash instead of a general service. If it is not cooling or keeps tripping, it needs diagnosis first - see aircon repair.

Location and parking

A service van needs parking for 30 minutes to 2 hours. Where parking is paid, such as the CBD, condos without visitor lots and commercial buildings, some providers pass that cost on.

GST

A GST-registered company must charge 9% GST. Check whether a quote includes it, or the final bill will be 9% higher than the headline price.

Brand and advertising

Established brands tend to charge more, and companies that rely heavily on paid search ads often price higher to cover their ad spend. A higher price is not always better service.

Hidden fees to check before you book

A low headline price is not always the cheapest quote. Ask whether these are included before comparing:

Watch out for

Transport or call-out fee: often $10 to $30 per visit on top of the per-unit price.
GST: a GST-registered company adds 9% if its quote is before tax.
Minimum units: a low per-unit price may only apply from 3 units.
Upselling on site: a general service turned into a chemical wash or gas top-up after arrival. Ask for the reason and photos.
Surcharges: for weekends and public holidays.

How to get the cheapest aircon servicing in Singapore

1
Service every unit in one visit
The price per unit drops from $47.84 for 1 unit to $20.19 each for 5.
2
Take an annual package
For 3 units, 4 visits a year cost $279.16 instead of $293.84 booked one by one.
3
Compare all-in prices
Add transport, GST and any minimum-unit rule to each quote before comparing headline prices.
4
Book outside the peak
Demand peaks around July. Booking earlier in the year makes slots and promotions easier to get.
5
Clean the filters yourself
Rinsing the air filters every 2 to 4 weeks keeps airflow up and delays the need for a chemical wash.
6
Do not skip servicing
A neglected unit often needs a chemical overhaul at $149.04 instead of a $47.84 general service.

Aircon servicing price FAQs

Most Singapore aircon companies charge $75 to $100 to service 3 units, $80 to $120 per unit for a chemical wash and $130 to $180 per unit for a chemical overhaul, often with a transport fee on top. StringsSG general servicing is $47.84 for 1 unit, $73.46 for 3 units and $100.97 for 5 units with transport included. A chemical wash starts at $82.80 and a chemical overhaul at $149.04.

General servicing for 3 aircon units is $73.46 with StringsSG, which is $24.49 per unit with transport included. Across Singapore, 3 units typically cost $75 to $100, so compare whether a quote includes transport before comparing the headline price.

Travel, parking and setup cost the same whether the technician services one unit or five, so that fixed cost is shared across more units. With StringsSG, 1 unit is $47.84 while 5 units are $100.97 - about $20.19 per unit. Servicing every unit in one visit is the cheapest way to book.

Our prices include transport, while most Singapore providers add a transport fee of around $20 on top of their per-unit price. With that fee set aside, the StringsSG price for 5 units works out to $16.19 per unit. The amount you actually pay for 5 units is $100.97, with nothing added.

A chemical wash costs $82.80 for 1 unit and a chemical overhaul $149.04 for 1 unit with StringsSG. Singapore companies typically charge $80 to $120 and $130 to $180 per unit respectively. A wash suits weak airflow or a musty smell; an overhaul, where the fan coil is taken off the wall, suits a unit that still cools poorly after servicing.

Gas top-up prices depend on the refrigerant and how much is needed, and typically range from $40 to $220 in Singapore - R32 costs more than R410A, which costs more than R22. StringsSG charges $106.72 for a half-tank top-up and $147.20 for a full tank per unit. Low gas usually means a leak, so the leak should be found and fixed first or the gas will escape again.

Yes. For 3 units serviced every 3 months, the StringsSG annual package is $279.16 a year, against $293.84 for four one-time bookings - a saving of $14.68. The visits are also scheduled for you, so servicing does not slip.

For normal home use in Singapore, service every 3 to 4 months. For 3 units that is $209.37 a year on a 3-visit StringsSG package, or $279.16 for 4 visits. Units that run daily, homes with pets and flats near main roads benefit from the shorter interval.

Not with StringsSG. The price shown before you confirm is the final amount, with transport included and no minimum booking fee. When comparing other quotes, check whether transport, parking, 9% GST or a weekend surcharge are added on top of the headline price.
