## What You Are Paying For

When you compare quotes for 

aircon servicing in Jurong

, the prices can look similar while the work behind them is very different. Some quotes cover a filter rinse and little else.

Our general aircon servicing runs an 8-step checklist on every unit, every time. That answers the question most people ask first: what is included in aircon servicing with us.

Here is what each step does and why it matters.

## The 8-Step General Aircon Servicing Checklist

### 1\. Filter cleaning

We remove the filters, wash them and dry them before they go back in. Clean filters restore airflow straight away and stop dust from reaching the coil.

Between visits, you can rinse them yourself. One Singapore maintenance cheat sheet from Renovate Ace suggests every two weeks for best results.

### 2\. Evaporator coil check and clean

The technician inspects the coil fins and cleans the accessible surface. Heavy grime deeper in the coil is noted, because it may need a 

chemical wash

[/aircon-chemical-wash/ →](/aircon-chemical-wash/)

 rather than general servicing.

That split is standard across Singapore. Homejourney’s 2026 guide describes general servicing as a surface-level job, while deeper dirt calls for a chemical wash or overhaul.

### 3\. Drain line flush

We push water through the condensate drain line to clear early slime before it turns into jelly sludge. This single step prevents most leaks.

Snowflake Aircon calls water leaks the second most common indoor unit complaint in Singapore. It also says a clogged drain pipe is the cause in most cases.

### 4\. Drain pan check

We check the pan under the coil for sludge, cracks and correct seating. That way, water flows to the drain instead of onto your wall.

### 5\. Refrigerant pressure check

Gauges confirm the system has the right refrigerant pressure. A low reading points to a leak that needs attention before cooling drops.

Slow leaks are easy to miss. Snowflake Aircon lists a gradual fade in cooling and ice on the pipes as typical warning signs.

### 6\. Thermostat test

We check that the unit reads the room temperature correctly and responds to the remote. It then cools when it should and stops when it should.

### 7\. Electrical check

Connections, the capacitor and other electrical parts are checked for signs of wear or overheating. The capacitor is the part we watch most closely, because it gives the fan and compressor their starting push.

A weak one often shows up as a slow fan start or a hum without the unit starting. A 2026 repair guide from Saces.sg puts a capacitor replacement at roughly S$80 to S$150 including labour, so catching it early is cheaper than a breakdown.

### 8\. Airflow and temperature test

Finally, the unit runs while we measure air temperature and flow at the vent. This confirms the unit is cooling properly before we pack up.

> **Why the last step matters**
> 
> A unit can look clean and still cool badly. The airflow and temperature test is how we prove the job is done, not just that parts were wiped.

## How Long It Takes

Most units take 1 to 2 hours, going by Homejourney’s 2026 guide to general servicing in Singapore. The real time depends on how dirty the unit is, how easy it is to reach and whether the outdoor unit is on a tight ledge. As a rough guide:

| Units | What affects the time |
| --- | --- |
| 1 unit | Condition of the unit and access |
| 2 units | Usually done back to back in one visit |
| 3 units | Multi-split outdoor unit checked once |
| 4 units | Plan for a longer visit; ask for an estimate |

We give you a time estimate with your fixed quote, so you can plan your day. Prices are S$50 for 1 unit, S$55 for 2, S$70 for 3 and S$85 for 4.

## Clean-Up and Test Run

Every unit is tested while you watch, and the area is cleaned up before we leave. Here is how the visit runs:

1.  The technician confirms the job and price with you.
2.  Covers go under the units before work starts.
3.  After servicing, the area is cleaned up and each unit is tested in front of you.
4.  You pay after the job, and the 90-day workmanship warranty starts from that day.

If you want the visit to run on time, a little preparation helps. Our guide on how to

 covers clearing space under units and condo booking rules.

## When General Servicing Is Not Enough

General servicing can’t fix every problem, and sometimes the checklist shows one that needs more. Common examples:

-   **Cooling still weak after servicing.** The coil or blower wheel needs a deeper clean.
-   **Musty smell that stays.** Mould on the blower wheel needs a chemical wash or overhaul.
-   **Low refrigerant pressure.** There is a leak that needs finding and fixing.
-   **Repeated drain blockages.** Sludge is coming from a dirty coil and pan.

In each case we explain what we found, show you if possible, and give a separate fixed quote. Nothing extra is done without your agreement.

How often you need general aircon servicing depends on use. For a unit that runs daily, Homemaster suggests every 3 to 4 months.

If your units are due, book a visit and we’ll run the full 8-step checklist with a fixed quote up front.

## Questions People Also Ask

### How long does servicing 3 units take?

It depends on the condition of each unit and how easy they are to reach. Ask when you get your quote and we will give you a time estimate for your units.

### Is gas checked during servicing?

Yes. Refrigerant pressure is checked on every unit as part of general servicing. If it is low, we explain and quote a leak check and top-up separately.

### Is the area cleaned after?

Yes. We clean up after the job and test each unit before we leave.

### Does general servicing include a chemical wash?

No. General servicing cleans the filter, checks and cleans the accessible coil surface and flushes the drain. A chemical wash is a deeper clean with solution, priced separately from S$80 per unit.
