If you’ve been servicing your aircon regularly but still notice it’s not as cold as it used to be, the problem is probably not how often you’re servicing — it’s how thoroughly.
Most aircon servicing in Singapore cleans the front of the evaporator coil and calls it done. The back of the coil, where most of the dust, grime, and mould actually accumulates, gets left alone. Over time that buildup restricts airflow, reduces cooling performance, drives up your electricity bill, and shortens the lifespan of your unit.
FoamJet aircon servicing fixes this. It’s Urban Company’s standard service for every aircon job in Singapore, and it’s built around one principle: clean the whole unit, not just the parts that are easy to reach.
What Is FoamJet Aircon Servicing?
FoamJet is an advanced aircon cleaning method that uses high-pressure foam to deep-clean both the front and back of the evaporator coil, along with other internal components including the filters, drainage tray, and blower wheel.
The foam penetrates into the coil and breaks down accumulated dust, grime, mould, and bacteria — debris that builds up over months of use and that a standard wipe-down cannot reach. Once the foam has worked through the unit, it’s jet-washed away, taking the loosened debris with it.
The result is a unit that’s clean throughout, not just on the surface.
How FoamJet Servicing Works — Step by Step
Pre-Service Airflow Measurement
Before the technician touches the unit, they measure airflow using an anemometer. This reading is captured in the Urban Company app as a baseline — so you have documented proof of where your aircon started.
Inspection and Preparation
The technician inspects the unit’s condition — checking for signs of mould, drainage blockages, or anything that might indicate a deeper issue beyond routine servicing.
High-Pressure Foam Application
Foam is applied to the evaporator coil — front and back — as well as the filters, drainage tray, and blower wheel. The foam breaks down and lifts accumulated dirt, grime, and microbial buildup from surfaces that standard cleaning doesn’t reach.
Jet Wash and Rinse
The foam, along with all the loosened debris, is rinsed away thoroughly. You’ll see the dirty water on completion — Urban Company technicians show this as part of the proof-of-work process.
Post-Service Airflow Measurement
Once the unit is dried and reassembled, airflow is measured again. The before-and-after readings are both captured in the app, so you can see the actual improvement in airflow from a single service.
Why Standard Aircon Servicing Falls Short
Standard aircon servicing — the kind offered by most providers in Singapore — typically covers the air filters and the front-facing surface of the evaporator coil. It’s quick, it’s cheap, and it gives the appearance of maintenance.
The problem is what it misses. Dust and debris accumulate primarily at the back of the evaporator coil, where airflow pushes them over time. Standard servicing doesn’t reach this area. The buildup continues, cooling efficiency drops, and eventually you’re told you need a chemical overhaul — a more invasive and expensive process involving full dismantling and chemical treatment.
FoamJet servicing is designed to prevent this. By cleaning the whole coil at every service, it removes the buildup before it reaches the point where a chemical overhaul becomes necessary.
FoamJet Aircon Servicing Prices Singapore
| Service | Price |
|---|---|
| FoamJet Aircon Servicing — no contract | $23/unit |
| FoamJet Aircon Servicing — annual contract (2x, 3x, or 4x per year) | $20/unit |
For context, standard aircon servicing from most Singapore providers runs $30–$45/unit — and doesn’t include the back-of-coil cleaning, anemometer readings, or proof-of-work documentation that comes with every UC job.
If your unit has heavier buildup that servicing alone can’t address, chemical overhaul is available from $160 for 1 unit.

What’s Included With Every FoamJet Service
Every Urban Company FoamJet aircon service includes:
- Full cleaning of evaporator coil — front and back
- Filter cleaning
- Drainage tray and blower wheel cleaning
- Before-and-after airflow measurement with anemometer
- Photos of coils before and after, captured in-app
- Dirty water shown on completion as proof of work
- Honest technician assessment — no hard-selling of additional services
How Often Should You Book FoamJet Servicing?
For most Singapore households, every 3 to 6 months is the right cadence. If you run your aircon most of the day — which is standard in Singapore’s climate — lean towards every 3 months.
An annual contract at $20/unit per service makes this easy to maintain without having to remember to rebook. You set the frequency — 2, 3, or 4 times per year — and Urban Company handles the scheduling.
For a typical Singapore home with 3 aircon units serviced 3 times a year, the annual cost works out to $180 — less than most households spend on a single chemical overhaul.
FoamJet Servicing vs Chemical Overhaul — Which Do You Need?
| FoamJet Servicing | Chemical Overhaul | |
|---|---|---|
| Cleaning depth | Front and back of evaporator coil | Full dismantling, chemical treatment |
| Frequency | Every 3–6 months | Only when heavily soiled |
| Price | From $20/unit | From $160/unit |
| Best for | Regular maintenance | Severely clogged or mouldy units |
The honest answer: most units that end up needing a chemical overhaul got there because regular servicing was skipped or was too superficial to prevent buildup. FoamJet servicing done consistently removes the conditions that make a chemical overhaul necessary.
If your unit hasn’t been properly serviced in over a year, or if you’re noticing significantly reduced cooling despite recent servicing, a chemical overhaul may be the right starting point. A UC technician will assess honestly and tell you which applies — there’s no incentive to upsell you on a service you don’t need.
What is FoamJet aircon servicing?
FoamJet is Urban Company’s standard aircon service. It uses high-pressure foam to clean both the front and back of the evaporator coil — the back is where most dirt accumulates and where standard servicing doesn’t reach. Every job includes before-and-after airflow measurements captured in the app.
How much does FoamJet aircon servicing cost in Singapore?
From $23/unit with no contract, or $20/unit on an annual contract (available at 2x, 3x, or 4x per year). Chemical overhaul starts from $160 for 1 unit if required.
How is FoamJet different from standard aircon servicing?
Standard servicing cleans the front of the evaporator coil. FoamJet cleans both front and back, where the real buildup happens. It also includes documented proof of work — airflow readings before and after, coil photos, and dirty water shown on completion.
How often should I service my aircon in Singapore?
Every 3 to 6 months for most households. If you run your aircon most of the day, every 3 months is more appropriate. An annual contract at $20/unit makes consistent servicing easier to maintain.
Do I need a chemical overhaul or will FoamJet servicing be enough?
For most units on a regular maintenance schedule, FoamJet servicing is sufficient. Chemical overhaul is for units with heavy mould, rust, or blockage that regular servicing can’t clear. A UC technician will assess your unit and advise honestly — no upselling.
Does Urban Company service all aircon brands in Singapore?
UC technicians are trained across all major residential aircon brands common in Singapore — Daikin, Mitsubishi, Panasonic, LG, Samsung, and others. Confirm your unit model when booking if you have a less common brand.
