1. Airconboy (Ah Boy)

The one that just tells you what it costs. Airconboy publishes the most detailed pricing in the trade: a general service from $40 for one unit, a chemical overhaul from $150 (dropping toward $100 a unit once you're doing four or more), plus gas top-ups and a troubleshooting fee it waives if you engage them. When most rivals ask you to request a quote, published per-unit tiers let you budget before anyone visits.

• Worth it: the one to call first if you hate surprises, since the per-unit price is published before anyone visits. The clarity is the value.

2. Airmaxx Aircon Servicing

If your units are overdue a deep clean, Airmaxx leans into chemical washing specifically, the heavier service that strips out the mould and grime a quick general service leaves behind. Worth a call when airflow has dropped or a unit has started to smell musty.

• Worth it: the call when a unit genuinely needs the heavier chemical clean rather than a routine service.
• Watch for: it is quote-only, so get the per-unit wash price in writing before booking.

3. 7Days Aircon Servicing

The name is the pitch: a same-week response built into how it positions itself. If a unit is dripping or dead and you'd rather not wait, this is the one set up to turn up quickly, with general servicing and chemical washes alongside the callouts.

• Worth it: the pick when a unit is dripping or dead and you would rather not wait.
• Watch for: fast callouts usually carry a premium, and the price is set when they arrive rather than when you call.

4. Marvellous Aircon Servicing

Covers both servicing and installation, which is handy if you're maintaining existing units and weighing a new one in the same call. A steady all-rounder for a standard service or a fresh fit-out.

• Watch for: ask for servicing and installation as separate line items so the install does not blur into the service bill.

5. Aircon Service & Repair Singapore (SC)

A general-service and chemical-overhaul outfit covering the standard islandwide callouts, quote on request. A straightforward pick for routine maintenance and a periodic deep clean.

Other names you'll have seen advertised

A few of the most heavily advertised brands are worth knowing by name, with what each is known for:

• SoCool, one of the most visible brands in the trade. Pricing is booking-driven rather than published, so ask for an itemised quote for your units.
• DW Aircon, the standout for transparency among the big brands: it publishes a full price table (general service $65–125 by unit count, subscription packages, gas top-ups), so you can see the number before you call.
• @bsolute Aircon, a 24-hour operation with a long history; worth a call for out-of-hours emergencies.
• LK Brothers, advertises general-service rates from as low as $19/unit; confirm exactly what that covers when you get your quote.

How much does aircon servicing cost in Singapore?

From the companies that publish rates (Airconboy and DW), the going prices are roughly:

• General service: about $40–65 for one unit, dropping per unit as you add more (e.g. ~$110–125 for four to five units).
• Chemical wash / overhaul: about $130–150 per unit, falling toward $100/unit at four-plus units, the deeper clean you need every 1–2 years, not every visit.
• Gas top-up: roughly $40–130 depending on gas type (R22 cheapest, R410/R32 more).
• Contract packages (3–4 quarterly visits) usually work out cheaper per visit than ad-hoc.

Rates move and vary by unit condition, so get the per-unit price confirmed before the technician starts.

How to avoid overpaying on aircon servicing

The pattern to know: a cheap general-service quote to get in the door, then a "your compressor is dying / gas is critically low / you need a chemical overhaul today" upsell once the technician is at your unit. Protect yourself: get the per-unit price and what's included in writing first, favour a company that publishes or itemises its rates, and be wary of on-the-spot "urgent" diagnoses, get a second opinion for anything over a couple of hundred dollars.

What customers actually report

Read the HardwareZone and Reddit threads on aircon servicing and the same complaint comes up: the on-the-spot upsell. A cheap servicing visit turns into a "gas leak" or "mould" finding, and you are pushed into a chemical wash at $80 to $150 a unit or a gas top-up there and then, sometimes with the technician saying the boss will scold them if you refuse.

Two patterns are worth knowing. Bait pricing: a $30-a-unit quote becomes closer to $50 once "GST and transport" are added. And the gas top-up tell: if a unit genuinely needs gas it has a leak, so a top-up on its own just leaks out again, which means a technician selling a top-up without finding the leak is either upselling or setting up a repeat charge.

The honest takeaway: an aircon needs a basic wash a couple of times a year, not a chemical wash every visit. Pick a fixed-price servicer, get the all-in per-unit price in writing before anyone starts, refuse "urgent" same-visit upsells, and get a second opinion before any gas or chemical job.

So which should you go with?

For most households, start with Airconboy, the one here with published per-unit pricing from about $40, so there is no on-the-spot guessing. If you need it done this week, 7Days is the fast-response pick; if you also need an install, Marvellous covers both. Whoever you call, hold them to a written all-in price and treat any same-visit "you urgently need a chemical wash" as your cue to get a second quote.

Aircon servicing in Singapore: quick questions

Which is the best aircon servicing company in Singapore?

It depends what you want. For published, per-unit pricing, Airconboy is the standout (general service from $40/unit, chemical overhaul from $150). For a proper chemical wash, Airmaxx specialises in it; for a fast, same-week turnaround, 7Days Aircon. DW Aircon also publishes a full price table if you'd rather see the number before you call.

How much does aircon servicing cost in Singapore?

A general service runs about $40–65 for one unit (cheaper per unit for more units); a chemical wash is roughly $130–150 per unit, falling toward $100 at four-plus. Gas top-ups run $40–130 by gas type. Contract packages are usually cheaper per visit than ad-hoc.

How often should I service my aircon?

A general service every 3–4 months for regularly-used units, and a deeper chemical wash roughly every 1–2 years (or when airflow drops, it smells musty, or it starts leaking). Contract packages bundle the quarterly services.

Is a chemical wash worth it, or is a general service enough?

A general service (clean filters, check gas, wipe down) is the routine maintenance; a chemical overhaul strips the coils and tray of mould and blockage that a general service can't reach. If your unit is leaking, smells musty, or hasn't had one in over a year, the chemical wash is worth it, otherwise the general service is enough.

How do I avoid getting scammed by an aircon company?

Get the per-unit price and inclusions in writing before work starts, favour a company that publishes or itemises its rates, and be sceptical of urgent on-the-spot upsells (gas "critically low", compressor "dying"). Get a second opinion on anything over a couple of hundred dollars.

Can these companies service my Mitsubishi, Daikin or Panasonic aircon?

Yes, the third-party servicers on this list work on all the major brands (Mitsubishi, Daikin, Panasonic, LG, Midea, Hitachi and the rest), and they come to you islandwide, so a "near me" search matters less than for a shopfront trade.

Use the brand's own official service centre only when your unit is still under warranty and the work is a warranty claim; for routine general servicing, chemical wash and gas top-ups, an independent from this list is usually cheaper and just as capable.

What do people recommend on Reddit for aircon servicing?

Reddit threads lean the same way: the per-unit price matters more than the headline, a quote that looks too cheap usually is, and the companies worth using are clear about what a service and a chemical wash include. The transparent-pricing outfits like Airconboy and DW come up positively.
