A shop fan-coil can use the printed service. A cassette cannot

Last updated 31 October 2026.

Shops in Singapore are full of wall-mounted fan-coils that have not been washed since the last tenant, and of ceiling cassettes that a residential price list cannot describe. The aircon page prices the fan-coil work: general servicing from S$38 a unit, or from S$25 a unit when there are five or more; a quarterly service of three to five units at S$120 to S$180 including a company-stamped receipt; a steam wash of two to four units at S$160 to S$280; an on-site chemical wash at S$75 to S$160 a unit, or S$320 to S$520 for three to four units; a dismantle overhaul at S$160 to S$240 a unit, three units on one visit S$480 to S$680. If your photo is that wall-mounted fan-coil, use those sentences. If your photo is a cassette in a grid, or a ducted unit above a shop ceiling, say quote on inspection. Do not ask for “S$38” because the word aircon appeared.

The symptom people book is water on the counter or a warm sales floor. The aircon page’s own order is: a blocked drain and a matted blower make the coil ice and the tray overflow. Gas is the suspect after the coil and the drain are clean. A full gas repair is quoted from the gauge on a dismantle overhaul. It is not folded into a vague “service”. We will not top up gas on a dirty coil and call it done.

A shop adds two permissions a flat does not. The mall may only allow the work before opening, and the overnight row of S$380 to S$650 is the permit-to-work admin and one hardware fix when the centre requires that slot. Washing four fan-coils is the aircon bands plus that slot if it is required, not the slot instead of the wash. An HDB shop that is installing a new aircon, especially into a civil defence shelter, is in HDB’s shop guide: shelter alterations including aircon need FSSD’s written approval. Servicing a unit that is already there is not that approval. Cutting a new opening is.

Curtains, blinds and roller shades are not part of this booking. A roller shutter is a different product and stays on the shutter page.

The filters come out, the drain is cleared, and the tray is cleaned. That is also the practical step against mosquitoes breeding in a wet tray, which the aircon page already ties to NEA’s concern. A shop tray above a food counter is the same water. Chemical wash stays on the wall for the units the page prices. Overhaul means the fan-coil comes off. A cassette does not “come off” the same way. Forcing the wall-unit method onto a cassette is the sloppy visit: panels bent, the ceiling grid stained, and the condensate still going into the shop because the pump was never the wall-unit drain.

Access in a trading shop is the ladder and the merchandise. A ladder over a glass showcase needs the stock moved, not a shoe on the glass. Height that matches the high-ceiling lamp page is a lamp problem, not an aircon discount. If the indoor unit sits above 3.6m, say so. The aircon bands do not include a scaffold. The scaffold sentence on the lighting page is for lamps. An aircon at that height is quote on inspection unless the written scope adds the access that page already prices for lights, and only if that is actually what is being done. We will not silently add S$220 because the ceiling looks high.

The receipt is a Homey Furnishing stamp for the visit that was done. A residential tenancy clause that wants a quarterly receipt is what that page describes. A shop lease might ask for a specialist’s certificate or a brand’s log. We do not pretend the stamp is that certificate. If the lease names another company for the cassette, book them for the cassette. Book this page for the wall-mounted units the bands describe.

Count the indoor units and photograph the face of each. Say wall-mounted, cassette, or ducted. Say if water is dripping and if the air is warm. Say whether the mall allows daytime work. Five wall-mounted units are the “from S$25” servicing sentence if that is all they need. One cassette in the same shop is a separate quote. Do not average them.

Condensate that stains the ceiling below is sometimes the drain and sometimes a slab leak. If the unit is dry and the ceiling is wet, read the ceiling page and the leak pages. Do not wash a dry coil and call the stain fixed.

Match the machine. The word aircon is not the band.

Questions a shop should ask

A shop aircon quote that cannot name the machine is a residential price list.

1. Is each indoor unit a wall-mounted fan-coil, a cassette, or ducted?
2. Is it dripping, warm, or both?
3. Do you need the quarterly receipt, and does the lease accept this company’s stamp?
4. Does the mall require the work before opening?
5. Is any unit above 3.6m?
6. Is this a new installation, especially in an HDB shelter?
7. Is the ceiling below wet while the unit is dry?
8. Are you asking for a gas top-up before anyone has washed the coil?

Grease and trading hours change the same machine.

The aircon page already states the bands and the order of diagnosis. This page does not add a commercial tariff. NEA’s mosquito point is the wet tray, which is why the tray is cleaned rather than deodorised. A gas repair stays outside the wash until the gauge says otherwise.

HDB’s shop guide requires FSSD approval before alteration works, including aircon, in a civil defence shelter, and a copy of that approval to HDB. Servicing an existing unit is not that submission. A new sleeve, a new drain through a slab, or a new outdoor unit on a common ledge can be. Town council and MCST rules on ledges are the netting page, not a licence to drill the facade.

A mall’s fitting-out checklist, where one exists, treats air-conditioning changes as works that need the centre and often the fire consultant if the system is shared. CapitaLand’s checklist is an example for its own buildings. It is not a rule that every heartland shop shares a central plant. Ask which plant you are on before you book a “unit wash” for a valve you do not control.

How you're charged

A job that already has a sentence on HomeySG uses that sentence. The hour is not added on top of a band unless the written scope says so. There is no fuel surcharge and no published night premium except the mall overnight row. A shop does not inherit a flat’s price just because the fitting looks similar.

Fan-coil bands are used when the machines match. Cassettes and ducted units are quote on inspection. The mall overnight row is extra only when the mall requires that slot. It is not a fifth aircon price.

Ways to keep the bill smaller

• Service all the wall units on one visit. The five-unit servicing sentence exists because the mobilisation is shared.
• Clear the stock under the unit before the technician arrives. Waiting time is not a hidden rate, but a second visit is a real cost.
• Do not buy a cassette and ask for the wall-unit wash. The quote will not match the invoice.
• Wash the coil before you discuss gas.

Every figure below is already on the aircon page or the mall page. A cassette is absent on purpose.

Anything not in that table is quote on inspection.
