Our Services

Normal Service

Normal Service

Regular maintenance keeps your aircon running efficiently before problems develop. Every three months, we clean filters, inspect coils for early dirt buildup, check drainage flow, and test cooling performance.

Taking a preventive approach stops minor issues from turning into expensive repairs later. Therefore, quarterly servicing protects your investment while keeping electricity costs predictable. And it doesn't even take that much time. Most units need just 45 minutes of attention.

Aircon Chemical Wash

Aircon Chemical Wash

When normal servicing doesn't resolve the issue, a chemical wash reaches deeper. Your unit might blow air but won't cool properly, or that musty smell returns within days. That's because dirt, mold, and algae have packed into spaces that regular maintenance can't access.

We dismantle the main components, treat them with non-corrosive chemicals that inhibit bacterial growth, and then rinse them thoroughly. As a result, the unit restores cooling without any rusty odors that ruin both your health and mood.

Aircon Chemical Overhaul

Aircon Chemical Overhaul

Some units need more than a chemical wash can provide. If your aircon makes grinding noises or leaks persistently, even after drainage cleaning, the contamination may run too deep for partial disassembly. That's when you need an overhaul.

That means every internal part is removed, chemically cleaned, and inspected for wear and tear. Moreover, we replace faulty components with your approval. This comprehensive approach brings severely neglected units back to near-factory performance within 3–4 hours.

Aircon Gas Top Up

Aircon Gas Top Up

Gas top-up only makes sense when pressure testing confirms low refrigerant and the leak is repaired. Most people don't know that these systems operate on a sealed loop, and as a result, the refrigerant doesn't evaporate naturally. Therefore, if the gas is low, something's broken.

We test first, locate the leak, repair it, and then refill the unit. Topping up without fixing leaks wastes your money because gas escapes again within months. We've turned away customers who didn't actually need this service.

Aircon Condenser Chemical Wash

Aircon Condenser Chemical Wash

Your outdoor unit sits exposed on the HDB ledge, accumulating dust, pollen, and bird droppings that rain doesn't wash away. Over time, condenser coils become clogged, blocking heat dissipation and forcing your compressor to work harder.

That's where condenser-specific chemical cleaning helps. We treat outdoor coils with solutions specifically designed for aluminum fins and copper tubing, removing buildup that restricts airflow. As a result, you get improved efficiency and lower electricity consumption.

Aircon Troubleshooting & Repair

Aircon Troubleshooting & Repair

We start with diagnosis, which could involve anything from a failing compressor, worn motor bearings, an electrical fault in the control board, or a blocked drainage system that triggers overflow sensors.

We identify the actual problem, explain what needs to be fixed, and then wait for your approval before proceeding. Moreover, same-day emergency AC service is available when your unit stops working during a heat wave.

Ledge Wash

Ledge Wash

HDB residents share common ledges with neighbors, and outdoor units need regular cleaning to function properly. Moreover, HDB can issue fines for poorly maintained condensers that drip excessively or look neglected during inspections.

Since ledge access requires proper licensing and safety protocols for high-rise work, we handle this service with appropriate equipment and permits. This ensures your outdoor unit remains compliant while allowing for proper heat dissipation.

Aircon Installation & Repair in Singapore

Aircon Installation & Repair in Singapore

Installation determines whether your air conditioner runs efficiently or causes problems from day one. We handle new installations, replacements, and relocations (while managing HDB permits), MCST approvals, bracket mounting, and drainage routing.

We begin with a complimentary site survey to assess compliance requirements before providing a quote. All brands are supported, with a 1-year workmanship warranty on installations.

How We Work

Step 1: Pre-work Inspection and Documentation

Every service begins with documenting the current condition of your air conditioner. This step includes photos of component wear, baseline temperature output measurements, and a visible damage assessment. We do this to create a reference point, allowing you to see exactly what has improved after our service.

Step 2: Timed Chemical Treatment Protocols

During chemical cleaning, we follow proper soaking protocols, without rushing to squeeze in more jobs. The chemicals require 15-20 minutes to break down accumulated biofilm effectively. The technician monitors the chemical reaction, adjusts concentration if buildup is severe, and ensures thorough rinsing before reassembly.

Step 3: Multi-point Verification After Service

After reassembly, we perform verification checks, including refrigerant pressure readings against manufacturer specifications, drainage flow testing under a full condensation load, and measuring the temperature drop at multiple vents to ensure even cooling distribution.

Step 4: Service Report and Maintenance Education

You receive documentation of what we found, what we cleaned, and what needs monitoring in future visits. Additionally, we provide you with maintenance basics, including proper filter removal techniques, warning signs that require immediate attention, and optimal thermostat settings tailored to your room size.

Why Choose ARC For Your Aircon Needs?

You Get To Work With Experienced Proactive Technicians
The average experience of our technicians in HVAC servicing is around 8 years or more. As a result, we tend to spot problems earlier, giving us enough time to do what’s required to prevent or fix. Let it be an unusual compressor sound that signals bearing failure, spotting corroded drain pans before they crack completely, or finding out which chemical concentrations work on stubborn biofilm without damaging aluminum fins. We’ll catch things during our routine service (stuff that other companies miss until components fail).

No Shooting In The Blind – Proper Diagnostic Equipment
Our team is equipped with state-of-the-art diagnostic equipment. We’ve spent quite a fortune on these gadgets and for good reason. Precise assessment is crucial when it comes to aircon repairs and servicing, as the workflow depends on the accuracy of the diagnostics. We use manifold gauges that accurately measure refrigerant pressure, infrared thermometers to verify cooling performance, and electronic leak detectors instead of relying on soap-and-water tests. As a result, we now know whether your unit needs a gas top-up or if the problem lies elsewhere.

Relationships With Part Suppliers Across The Country
We maintain relationships with parts suppliers across Singapore, which means genuine replacement components arrive within hours, unlike other companies that may claim they’ll return the next week when the part arrives. We understand how difficult it is to live without a properly functioning air conditioning unit in Singapore’s heat and humidity, which is why we prioritize fixing everything right the first time because we show up prepared. Additionally, direct supplier access means better pricing on components (savings we pass on to you).

A chemical overhaul is more comprehensive - every internal part is removed, chemically cleaned, and inspected for wear. It's needed when your aircon makes grinding noises or leaks persistently, taking 3-4 hours to complete.

If gas is low, something is broken. We test first, locate the leak, repair it, and then refill the unit. Topping up without fixing leaks wastes your money because gas escapes again within months.
A chemical wash typically takes 1.5 to 2 hours per unit. This includes removing the fan coil unit, filters, and drain pan, soaking each part in chemical solution, thorough rinsing, reassembly, and testing. We also tarp your floor and clean up completely before leaving.
Yes, we are fully licensed for ledge access and ensure all required permits are secured before work begins. Our installations comply with Building Control Act requirements, with drainage routed to approved outlets. We use proper safety equipment for high-rise work, protecting you from HDB violations that can result in fines.
Yes, you can book in the morning and receive service the same afternoon, subject to time slot availability. We also offer after-hours and weekend appointments. Once confirmed, you'll receive a two-hour arrival window, followed by a WhatsApp notification thirty minutes before our technician arrives.
If the same problem returns within thirty days, we'll fix it at no additional charge. All installations come with a comprehensive one-year workmanship warranty. We're confident in the quality of work we deliver and will address any issues promptly without charging extra.
No. What we quote is exactly what you pay. If we discover additional work is needed during servicing, we clearly explain the issue, provide a separate quote, and proceed only with your approval. You will never have billing surprises.
This usually happens when dirt clogs the coils and algae blocks your drainage pipe. Moisture breeds mold inside your unit within months of use. Not only is your unit unable to cool properly, but it also costs 30% more in electricity because the compressor works overtime. A chemical wash can reach these problem areas that regular cleaning can't access.
We support all major air conditioning brands for installation, repair, and maintenance. Our technicians have an average of 8+ years of experience in HVAC servicing across different brands and systems.
