Aircon servicing in Singapore costs $49.05 for one unit at Lion City Aircon, falling to $21.80 per unit once you book five or more. A chemical wash is $87.20 per unit, a chemical overhaul starts at $163.50, and a gas top-up runs $87.20 to $218 after a $87.20 troubleshooting visit. Every figure on this page includes 9% GST, and every figure is also shown before GST so you can compare like for like.
The price you see here is the price on your invoice. No transport fees, no quotation fees, no surprise add-ons at your door. Our technicians do not earn commissions on upsells, so nobody has a reason to find problems your aircon does not have.
What actually changes the price
Four things move an aircon servicing quote in Singapore, and only one of them is the company you pick:
- How many units. This is the big one. The technician is already at your flat, so the second, third and fourth units cost less than the first. Our per-unit rate falls from $49.05 to $21.80 between one unit and five.
- What the unit needs. A routine service is not a chemical wash, and a chemical wash is not an overhaul. Paying for the deeper clean when the routine one would do is the most common way people overspend.
- The type of unit. Wall-mounted units are the quoted rate. Ceiling cassettes and ducted units take longer and need ladder access, so they are quoted per site.
- Condition. A unit that has not been touched in three years may need a wash before routine servicing will achieve anything. We tell you that before starting, not after.
Why the cheapest quote often is not the cheapest
Rates advertised in Singapore run from well under $20 a unit to over $90. The low end of that range is usually not a price, it is an entry fee: the technician arrives, finds a problem, and the $20 service becomes a $300 invoice. We wrote up exactly how that works in why a $20 aircon servicing becomes $300.
The test is simple. Ask what the advertised price includes, ask what the most likely add-on is, and ask for the figure in writing before anyone comes. A company that publishes its full list has already answered all three.

What we never charge
No transport fees. No fee for quotations on WhatsApp. No commission for our technicians on anything they recommend, which is why our reviews keep mentioning that we told customers NOT to buy a chemical wash they did not need.

Frequently asked questions
How much does aircon servicing cost in Singapore?
Our general servicing is $49.05 for one unit including GST, $65.40 for two, $81.75 for three, $98.10 for four, and $21.80 per unit from five units up. Advertised rates across Singapore vary widely, so check what any quote includes before comparing it with ours.
How much does an aircon repair cost?
We publish one repair figure: the $87.20 troubleshooting visit, waived if you proceed with the work. The repair itself is quoted on site once we know what has actually failed, because replacement part prices in Singapore move with supply and a figure published today would be wrong in three months. You get the number before we touch anything.
What does it cost to service a ceiling cassette or ducted unit?
Those are quoted per site rather than at the wall-unit rate. They take longer, need ladder access, and have a drain pump and float switch to check. Tell us the unit type and location and we will price it properly. See our guide to ceiling cassette and ducted systems.
How often should I book servicing at these rates?
Every three months suits most Singapore homes. If you are booking quarterly for several units, the annual contract at $174.40 a year works out cheaper than four separate visits and includes a gas top-up. See how often to service your aircon.
Why do you publish prices when other companies hide them?
Because hidden pricing is where upselling lives. Publishing the full list keeps us honest and saves everyone time. The number on this page is the number on your invoice.
Is GST included in your prices?
Both columns are shown above. The first column is before GST, the all-in column includes the 9% GST you will actually pay. No other charges are added.
Do you charge more on weekends or for far locations?
We serve the whole of Singapore with no transport fees. Booking is by appointment on WhatsApp at +65 8818 5781 and we confirm the exact price in writing before we come.
Why is the troubleshooting fee waived if I proceed?
The fee covers our time to diagnose properly. If you go ahead with the fix, that time is part of the job, so we do not charge it twice.
