Professional Cleaning, Inspection & Aircon Maintenance for Homes and Businesses
Keep your air conditioner clean, cooling properly and easier to maintain with professional aircon servicing from ALV Aircon. We service HDB flats, condominiums, landed homes, offices, retail spaces and commercial properties across Singapore.
Our technicians clean and inspect key air-conditioning components, check drainage and cooling performance, test the unit after servicing and explain any issue that needs attention before additional work is carried out.
I booked ALV Aircon Servicing for my condo in Jurong East. The technician arrived on time, cleaned the units carefully, and explained everything clearly. My aircon cools much better now.
Our office aircon needed servicing before a busy week. The team responded quickly, completed the work neatly, and the cooling improved immediately. Great customer service from start to finish.
We have used ALV Aircon Servicing several times for regular maintenance. Their pricing is fair, the technicians are polite, and they never recommend unnecessary work. Very satisfied with the service.
Routine servicing is right for regular maintenance. If something is wrong, start with the symptom so the technician can determine whether cleaning, diagnosis, chemical washing, repair or refrigerant service is the better next step.
| What you notice | Best starting point | Why |
|---|---|---|
| Aircon is cooling normally but due for maintenance | General Aircon Servicing | Routine cleaning, drainage checks and operating checks. |
| Aircon not cold / weak cooling | Inspection or Diagnostic | Poor cooling can have several causes; avoid assuming it is always gas. |
| Water leaking from indoor unit | Drainage Inspection / Diagnostic | Blocked drainage is common, but other faults can also cause leakage. |
| Musty smell, visible dirt or mould-like buildup | Chemical Wash Assessment | Deeper cleaning may be useful when routine servicing cannot remove the buildup. |
| Noisy, vibrating, blinking or switching off | Aircon Repair / Diagnostic | These symptoms can point to mechanical, electrical, sensor or control issues. |
| Refrigerant level confirmed low | Gas Top-Up / Refrigerant Service | Refrigerant service should follow a check of the system condition and cause. |

General servicing focuses on cleaning, inspection and functional checks that help keep the fan coil unit operating reliably.
Choose by condition and symptoms not by forcing every aircon into the same service package.
| Service | Best for | Main focus | ALV published price | Typical time |
|---|---|---|---|---|
| General Aircon Servicing | Routine preventive maintenance | Filters, fan coil, drainage, airflow and operating checks | From $30/unit | About 30–45 min/unit |
| Chemical Wash | Heavy dirt, odour, mould-like buildup or weak performance after routine cleaning | Deeper cleaning of coils, filters and drainage areas using specialised cleaning solution | From $100/unit | About 1–1.5 hr/unit |
| Chemical Overhaul | Units needing substantially more dismantling and deep cleaning | Extensive dismantling, cleaning, reassembly and testing based on unit condition | Request quote | Depends on system |
| Diagnostic / Repair | No cooling, leaks, noise, error codes, shutdowns or recurring faults | Root-cause inspection and repair recommendation | Diagnostic from $60 | Depends on fault |
| Gas Top-Up | Confirmed refrigerant-related issue | Check refrigerant condition and refill when required | From $80 | Depends on system |

Weak cooling can come from restricted airflow, dirty components, condenser issues, component faults or refrigerant problems. Start with inspection when the cause is unclear.
Drainage blockage and dirt buildup are common causes, but the source should be checked before deciding on drain clearing, cleaning or repair.
Dirty filters, blower buildup, coil condition or another system issue can reduce airflow. Routine cleaning helps only when dirt is the main cause.
Odour can develop when moisture, dust and internal buildup remain in the fan coil unit. Deeper cleaning may be needed after inspection.
Buzzing, rattling, vibration or grinding should be checked for loose parts, fan issues, debris or another mechanical/electrical problem.
Brand-specific fault codes can point to sensor, control, electrical or system issues. Diagnostic inspection is more useful than guessing.
No. Refrigerant circulates inside a sealed system and isn't consumed through normal use. If refrigerant levels are genuinely low, that usually points to a leak the cause should be investigated rather than treated as something that simply runs out over time.
Book a DiagnosisDifferent systems use different refrigerants our technicians match the correct type to your unit.
| Refrigerant | Where it's used |
|---|---|
| R22 | Common in older aircon models and legacy systems designed before current refrigerant standards. |
| R410A | Widely used in modern aircon units, offering efficient cooling and stable performance. |
| R32 | A more energy-efficient, lower-impact refrigerant used in newer air conditioning systems. |
Tell ALV what the aircon is doing weak cooling, leakage, smell, noise or routine maintenance and start with the appropriate service.
Share your location, number of units and whether you need routine servicing or help with a problem.
ALV confirms the requested service and appointment before the visit.
The technician checks condition, airflow, drainage and operating symptoms.
Routine cleaning is carried out according to the unit's condition and system type.
The system is run after servicing so airflow, cooling and drainage can be checked.
If repair, chemical cleaning or refrigerant work is recommended, the next step is explained before additional work.
ALV already has useful before-and-after proof. Keep it prominent and explain what the customer is looking at.
Built-up dirt on the cooling surface can restrict heat transfer and airflow. Cleaning the coil supports normal cooling performance and fan-coil airflow.
The outdoor condenser rejects heat from the system. Dirt and debris around the condenser can affect heat transfer and overall aircon performance.
ALV's current guidance recommends around every three months for normal residential use, with more frequent servicing for systems that run for long periods each day.
For heavy daily operation, every one to two months may be more appropriate depending on dust, usage and operating conditions. Offices and commercial properties may benefit from a scheduled maintenance plan.
A chemical wash should not be booked only because a calendar date has arrived. It makes more sense as a deeper-cleaning option when the condition of the unit justifies it.
For units that need a regular schedule rather than one-off visits.

ALV currently publishes regular aircon servicing from $30 per unit. Final cost can depend on unit count, system type, condition and whether additional work is required.
A normal service focuses on routine cleaning, inspection and testing. ALV's existing servicing information includes filter cleaning, fan-coil cleaning, drainage checking or clearing, cooling-performance checks and a final test of the unit.
ALV's current servicing page states that one standard unit usually takes around 30–45 minutes. A chemical wash can take around 1–1.5 hours per unit depending on condition.
For normal residential use, ALV currently recommends around every three months. Systems that run for long hours each day may need more frequent servicing.
General servicing is routine cleaning and inspection. A chemical wash is a deeper cleaning process for internal buildup, odour, mould-like contamination or performance problems that normal servicing cannot adequately address.
Not necessarily. A blocked drainage line or dirt buildup can contribute to leakage, but other faults are possible. The cause should be inspected before deciding on general servicing, drain clearing, chemical cleaning or repair.
No. Weak cooling can have several causes. Refrigerant should be checked as part of diagnosis rather than assuming every cooling problem needs gas.
The technician can explain the issue and recommended repair. Repair work and replacement parts are separate from a normal servicing visit.
