Aircon Chemical Wash in Singapore

Chemical Wash, Jet Wash or Full Overhaul

The short answer

What is an aircon chemical wash?

A chemical wash uses a cleaning solution to loosen grime that a brush or water alone can leave behind, then rinses it away. The name can mean three different jobs, which is why three quotes can look nothing alike.

BeeChem Washβ„’Sprayed in place. Coils and blower are jet-sprayed with our BeeChemβ„’ solution, with the blower left in.From $75
Chemical Jet WashStays on the wall. A stronger chemical loosens the sludge, then a high-pressure jet flushes it out.From $100
Full Dismantle Chemical OverhaulComes down. The fan coil is fully dismantled, every part is washed, then it goes back together.From $160

Our brochure calls the middle one Chemical Overhaul Jet Wash. Same job, longer name, and here's how an aircon jet wash works. A wash takes about 30 to 40 minutes per unit, or about 90 minutes for a 3-unit HDB. As a guide, most homes need a Chemical Jet Wash around every 1.5 years and a Full Dismantle Chemical Overhaul around every 3. Not sure which you need? WhatsApp us a photo and we'll tell you, including when plain general servicing is enough.

AirCon Chemical Wash FAQ

Popular questions that Singaporeans ask about chemical wash.

How much does an aircon chemical wash cost?

It depends on how deep you go. BeeChem Wash is from $75 for 1 unit with compressor clean. A Chemical Jet Wash, washed while mounted, is $100 for 1 unit, $180 for 2, $240 for 3, $280 for 4 and from $350 for 5 or more. A Full Dismantle Chemical Overhaul is $160 for 1 unit, $260 for 2, $360 for 3, $460 for 4 and from $560 for 5 or more. No GST.

What is included in the price? Does it cover the outdoor compressor?

Our prices cover the indoor fan coil unit and a compressor clean. A chemical wash replaces your routine servicing for that visit, so you will never be charged for both on the same unit. Chemical washing for the outdoor condenser can be left out if you prefer to only service the indoor units. WhatsApp us for a detailed quote.

How long does the process take?

  • Per Unit: Approximately 30 to 40 minutes, depending on the model and condition.
  • Standard 3-Unit HDB Setup: Plan for about 90 minutes.

When do I actually need a chemical wash vs. a general service?

We only recommend a chemical wash if your unit exhibits specific symptoms of deep-seated grime. If your aircon is simply dusty, a standard general service is more than enough.

Will you push me to get a chemical wash if I don't need it?

No. We believe in transparent advice over quick sales. Our team will assess your units on-site and let you know if a standard service is sufficient.

How frequently should this be done?

We don’t put chemical washes on a rigid schedule. As a guide, a Chemical Jet Wash suits most homes around every 1.5 years and a Full Dismantle Chemical Overhaul around every 3 years, sooner if symptoms appear. Regular general servicing helps slow the buildup in between.

What is the difference between a general service and a chemical wash?

General servicing is a non-chemical clean: filters washed, coil brushed and vacuumed, blower taken out and brush-cleaned. BeeChem Wash sprays the coils and blower with our BeeChem solution, with the blower left in place. A Chemical Jet Wash cleans the fan coil while it is mounted, and a Full Dismantle Chemical Overhaul fully dismantles the unit.

Will the chemical solution damage my aircon?

We use aircon-grade, aluminium-safe chemical agents made for fan coils, then rinse them off thoroughly with a high-pressure water jet. Damage usually comes from harsh chemicals or incomplete rinsing, which is why we are careful about both.

Which areas in Singapore do you service?

We cover all locations across Singapore, including HDB flats, condominiums, landed properties, and small commercial spaces from Tampines to Jurong. Same-day appointments are often available depending on your location.

What is an aircon jet wash?

A jet wash cleans the fan coil while it stays mounted on the wall. A chemical solution loosens the sludge, then a high-pressure jet flushes it out, with a wash bag catching the water. At BeeHonest it is $100 for 1 unit, $90 each for 2, $80 each for 3 and $70 each for 4 or more. More on how an aircon jet wash works.

Is a chemical wash necessary?

Not always. If your aircon is simply dusty, general servicing is enough, and we will tell you so. A chemical wash makes sense for signs of deep grime, such as leaking from a sludgy drain line, weak or warm air, black spots on the vents, or a musty smell that comes back after servicing.

Can I chemical wash my aircon myself?

We would leave this one to a technician. It means opening the unit, using chemicals near electrical parts and rinsing with a high-pressure jet. Washing the filter is a job you can do yourself, and our guide on how to clean an aircon filter shows you how.

What chemicals do you use?

Aircon-grade, aluminium-safe chemical agents made for fan coils, which are then rinsed off thoroughly.

Is an aircon chemical wash a scam?

The wash itself is a real service. The worry is being sold one you don’t need, or paying for one that only sprays the surface. So ask what will be washed, whether the unit gets opened up, and what the technician found that points to a wash. If your aircon is only dusty, general servicing is enough, and we will say so.

Is there a warranty on a chemical wash?

Yes, a 30-day servicing warranty. If the same problem comes back within 30 days of your service, WhatsApp us and we’ll come back and fix it free. It covers our labour and workmanship. Replacement parts aren’t included.
