Aircon Repair and Servicing in Singapore — Fix Not Cold, Leaks and More
Diagnostic-First Approach When your unit breaks down, we use a diagnostic-first approach rather than relying on guesswork. If you are dealing with an aircon not cold situation, we physically inspect the aircon fan coil and cooling coil before recommending an aircon repair. This ensures we fix the actual root cause of the problem, saving you from paying for unnecessary parts.
27 Years of Practical Experience Operating since 1997 means we have seen every major fault across every HDB and condo layout in Singapore. We understand that modern systems, like an inverter aircon, require a vastly different diagnostic approach compared to older fixed-speed units. Our technicians carry the right testing tools to accurately diagnose sensitive electronic boards and compressor faults.
Transparent Pricing Before Work Starts You will never be shocked by a hidden bill at the end of our visit. We clearly explain the aircon servicing price upfront based on our findings. Whether you need a simple drainage clear-out or a complex part replacement, our ac service price is always finalized with you before any physical work begins.
Certified Experts You Can Trust.
Aircon issues are rarely solved by guesswork. Our technicians follow a structured checklist to identify what’s affecting cooling performance, airflow, drainage, and system stability. Whether you need regular aircon servicing in Singapore or support for an aircon that is not cold, we recommend only what the unit actually needs.

General Aircon Servicing
Regular upkeep is the foundation of a healthy cooling system. Our comprehensive aircon servicing clears everyday dust and prevents minor water leaks from developing. Booking routine aircon maintenance in Singapore ensures your unit runs quietly and efficiently all year round.
Chemical Wash
When dirt solidifies inside the machine, a standard wipe-down is no longer effective. An aircon chemical wash safely flushes the internal aircon cooling coil and drainage pan with specialized solutions. You will know you need this when the fan coil looks visibly black or the unit starts blowing warm, musty air.
Chemical Overhaul
An overhaul goes one step further than a standard aircon chemical wash. We completely dismantle the indoor unit, bringing the parts down to be heavily scrubbed and treated. This intensive process restores severely neglected units back to factory-level cooling performance.
Aircon Repair
When parts break, you need a contractor who can source replacements quickly and install them correctly. Our aircon repair in Singapore covers everything from faulty capacitors and blown fuses to complete motor replacements. We handle complex air con repair in Singapore directly, ensuring your downtime is kept to an absolute minimum.
Gas Top-Up
If your system is lacking refrigerant, it simply cannot produce cold air. However, an air con gas top up is not a magic fix for every cooling issue. We always test your system pressure first, as blindly pumping gas into a choked system will damage the compressor.
Aircon Not Cold Troubleshooting
The most common complaint we hear is an aircon not cold. This is typically caused by one of five issues: a dirty fan coil, a blocked cooling coil, a drainage fault, gas loss, or a broken fan motor. For an inverter aircon, the issue might also stem from a tripped sensor or PCB fault, which our technicians will test for on the spot.
Honest Pricing for Singapore Homes
We keep our rates competitive without compromising on the quality of our workmanship. Your final aircon servicing price will depend on the number of units, the type of service required, and whether specialized parts are needed for a repair.

What you can expect:
- Clear pre-check and scope confirmation
- Proper cleaning of key components (based on service type)
- Drainage inspection to reduce leakage risk
- Performance checks after servicing

Frequently Asked Questions.
It depends on usage. Daily-use units typically need more regular servicing than occasional-use units. If your airflow drops or cooling becomes inconsistent, it’s usually time to service.
Standard servicing typically includes inspection, filter cleaning, drainage checks, basic cleaning of accessible parts, and performance verification after servicing.
Not always. “Not cold” can be caused by dirty coils, airflow restriction, drainage issues, fan problems, or other faults. Gas top up only makes sense when refrigerant-related issues are confirmed.
Chemical wash is commonly used when standard servicing is not enough to restore cooling performance. Chemical overhaul is deeper and usually reserved for severe buildup or recurring problems.
Yes. If troubleshooting points to a repair need, we explain the cause and options, then proceed only with your approval.
Pricing depends on the number of units, system condition, and service type (standard, chemical wash, overhaul). Share your unit details and we can give a clear quote range before booking.
We confidently perform aircon repair on Mitsubishi, Daikin, Panasonic, LG, Samsung, Fujitsu, Carrier, Midea, York, and many others. Because we have been operating for nearly three decades, we have deep familiarity with both legacy models and the newest smart systems.
Aircon fan coil cleaning is part of routine maintenance where we use vacuums and brushes to remove surface dust. An aircon chemical wash uses specialized, safe alkaline solutions to dissolve hardened grime and bacteria deep inside the coil fins. A chemical wash restores cooling efficiency when normal cleaning is no longer enough.
Yes, we fully service and repair all inverter aircon units. Inverter technology requires specific diagnostic knowledge because the compressor speed is controlled by complex electronic boards rather than simple on/off relays. Our technicians are trained to accurately test these components to prevent misdiagnosis.
