Have you ever felt like your air conditioning is blowing warm air right when you need it most? Many Singaporeans face this exact frustration when temperatures spike up to 35°C during the April to June heatwaves. An aircon chemical overhaul is often the exact solution needed to fix a struggling system.
James Tan and Sandra Lim founded iCare Aircon in 2016 with a clear vision to provide high-standard cooling solutions. Our team has found that a standard wash simply cannot clear out years of hidden, stubborn grime.
This intensive reset makes a huge difference for older units.
You will be amazed at how quickly a proper deep clean restores that crisp, icy breeze to your room. We are going to walk you through the exact steps of this process, sharing a few insider tips along the way. Grab a cup of coffee, and let’s explore how to get your home perfectly chilled again.
When an Aircon Chemical Overhaul Is the Right Choice
A regular chemical wash works perfectly fine for most local households on a yearly basis. This basic tier keeps fresh systems running smoothly.
We always recommend stepping up to an overhaul when standard maintenance stops delivering results. A recent Statista study highlights a 3.82% volume growth in Singapore air conditioners through 2026, meaning a massive number of aging systems now need this level of care.
These older setups often display clear warning signs that a basic wipe-down cannot fix. Our technicians look for several specific triggers before suggesting this intensive service.
You should consider this upgrade if you notice any of these common issues:
- The unit is 7+ years old with no prior overhaul history.
- A musty odour or weak airflow returns shortly after a recent chemical wash.
- The drainage tray shows visible cracks or heavy scale buildup.
- Your fan blade feels out of balance or makes mechanical grinding noises.
- Coastal-facing properties have exposed the condenser to years of salt-laden air.
Your system probably just needs standard servicing if it is under 5 years old and well-maintained. A popular multi-split system, like a System 3 from Daikin or Mitsubishi, will usually warn you by failing to drop below 24°C when it desperately needs a deep clean.
We will always give you an honest assessment before starting any work. Paying for an unnecessary upgrade is frustrating, so our team makes sure you only get what you actually need.
What’s Different About an Overhaul
A standard wash only treats the coils and fan while they are still hanging on your wall. This surface-level approach leaves hidden dirt trapped in the back crevices.
We completely remove the indoor unit from the wall to perform a true overhaul. This allows us to separate every single component for a thorough inspection.
The Complete Dismantling Process
Taking the unit down is the only way to reach the mechanical parts that a basic wash misses. You would be surprised by how much dust accumulates behind the blower wheel over a few years.
Our approach ensures that absolutely nothing is left hiding in the dark corners of your machine. The specific steps include:
- Indoor unit dismount: The entire fan coil unit comes completely off the wall.
- Component separation: The fan blade, motor, drainage tray, coil cover, and blower wheel are removed individually.
- Chemical soak: Parts are submerged in alkaline-based chemical agents to dissolve the deepest buildup.
Precision Inspection and Reassembly
A thick layer of biofilm in the drainage tray is an insider secret behind most unexpected condo leaks. This slimy buildup blocks water flow and ruins your freshly painted walls.
We aggressively target this scale buildup during the cleaning phase to prevent future water damage. The hardware inspection phase is just as crucial for long-term reliability.
This ensures every moving part operates smoothly and quietly. Our remaining steps focus on mechanical integrity and final testing:
- Mechanical inspection: We check fan motor bearings, gasket integrity, drainage tray wear, and fan balance.
- Vacuuming: The sealed system is vacuumed before re-charging the gas, where applicable.
- Reassembly + cooling test: A full performance test is completed before we leave your home.
Transparent Pricing: Wall-Mounted and Cassette
General aircon servicing in Singapore typically starts around S$40 to S$65 per unit. A quick wipe-down saves money upfront, but it will not resolve deep-seated mechanical problems.
We structure our rates to give you absolute clarity before any tools come out of the bag. Replacing a fried compressor can easily cost over S$800, making a S$120 overhaul a smart financial decision.
Here is a quick look at why a deeper clean makes economic sense for struggling machines:
| Service Level | Typical Cost | Best Suited For |
|---|---|---|
| Standard Wash | S$40 - S$65 | Routine 3-month upkeep |
| Chemical Overhaul | From S$120 | Severe clogs, leaks, and odours |
| Component Replacement | S$800+ | Total system failure |
Our transparent pricing brackets cover the most common setups found in local properties. The 5-unit residential pack offers excellent value for larger HDB flats or landed homes running a System 4 or System 5 configuration.
| Unit type | Price band |
|---|---|
| Single fan coil overhaul | S$120-180 per unit |
| 5-unit residential pack | S$500-600 |
| Cassette overhaul (ceiling-mounted) | S$390-450 per unit |
You get a fixed quote before the physical work actually begins. Unexpected issues sometimes pop up, like discovering a completely failed Printed Circuit Board, or PCB, behind the cover.
We will immediately stop work and quote that specific repair separately for your approval. This strict policy ensures you never face surprise charges on your final bill.
Backed by 90-Day Warranty + 7-Day Follow-Up
Many budget servicing companies only offer a standard 30-day guarantee on their work. A short window simply does not give you enough time to verify that a complex issue is truly resolved.
We provide the exact same extensive warranty for an overhaul as we do for every other iCare service. A full 90-day window covers an entire quarter of heavy, daily cooling.
This timeframe is essential for spotting slow freon gas leaks or subtle thermistor faults that might take weeks to appear. Our comprehensive protection plan includes:
- 90 days workmanship coverage for absolute peace of mind.
- A free 7-day follow-up check to ensure the system is running perfectly.
- A 100% fix guarantee specifically on the overhaul scope.
You deserve to know that the job was done right the first time. A persistent fault might return within 90 days, indicating something we should have caught during the initial inspection.
We will immediately re-attend to your property entirely free of charge. Fixing the root cause of your cooling problem is our only goal.
