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.

Start with the problem, not the upsell

What Does Your Aircon Need?

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.

Routine servicing scope

What Is Included in General Aircon Servicing?

General servicing focuses on cleaning, inspection and functional checks that help keep the fan coil unit operating reliably.

  • ✓
    Air filter cleaning
    Remove dust and debris that restrict airflow.

    Fan coil unit cleaning
    Clean accessible areas of the indoor FCU.
  • ✓
    Cooling coil & blower check
    Inspect dirt buildup and accessible surfaces.
  • ✓
    Drain pan & condensate drainage check
    Check for buildup or signs of blockage.
  • ✓
    Cooling & airflow check
    Assess operation after cleaning.
  • ✓

Problem-led content

Common Aircon Problems We Inspect

These are the searches customers make before they know which service to book. Answer them on the main page instead of forcing users back to Google.

Aircon Not Cold

Weak cooling can come from restricted airflow, dirty components, condenser issues, component faults or refrigerant problems. Start with inspection when the cause is unclear.

Aircon Leaking Water

Drainage blockage and dirt buildup are common causes, but the source should be checked before deciding on drain clearing, cleaning or repair.

Weak Airflow

Dirty filters, blower buildup, coil condition or another system issue can reduce airflow. Routine cleaning helps only when dirt is the main cause.

Musty Aircon Smell

Odour can develop when moisture, dust and internal buildup remain in the fan coil unit. Deeper cleaning may be needed after inspection.

Unusual Aircon Noise

Buzzing, rattling, vibration or grinding should be checked for loose parts, fan issues, debris or another mechanical/electrical problem.

Blinking Light / Error Code

Brand-specific fault codes can point to sensor, control, electrical or system issues. Diagnostic inspection is more useful than guessing.

Does an Aircon That's Not Cold Automatically Need a Gas Top-Up?

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.

Refrigerant compatibility

Refrigerant Types We Work With

Different systems use different refrigerants our technicians match the correct type to your unit.

RefrigerantWhere it's used
R22Common in older aircon models and legacy systems designed before current refrigerant standards.
R410AWidely used in modern aircon units, offering efficient cooling and stable performance.
R32A more energy-efficient, lower-impact refrigerant used in newer air conditioning systems.

Not Sure What Service to Book?

Tell ALV what the aircon is doing weak cooling, leakage, smell, noise or routine maintenance and start with the appropriate service.

STEP 05

Test Cooling & Drainage

The system is run after servicing so airflow, cooling and drainage can be checked.

STEP 06

Real service evidence

Before & After Aircon Cleaning Results

ALV already has useful before-and-after proof. Keep it prominent and explain what the customer is looking at.

Before and after aircon coil cleaning by ALV Aircon

Cooling Coil Cleaning

Built-up dirt on the cooling surface can restrict heat transfer and airflow. Cleaning the coil supports normal cooling performance and fan-coil airflow.

Before and after condenser cleaning by ALV Aircon

Condenser Unit Cleaning

The outdoor condenser rejects heat from the system. Dirt and debris around the condenser can affect heat transfer and overall aircon performance.

Maintenance frequency

How Often Should You Service Your Aircon?

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.

Practical maintenance guide

  • 1
    Normal home use
    Around every 3 months.
  • 2
    Long daily use
    Potentially every 1–2 months depending on conditions.
  • 3
    Office / commercial
    Use a planned servicing schedule based on operating hours and system load.
  • 4
    Chemical cleaning
    Condition-based rather than automatic.

Aircon Servicing FAQs

Answer the questions customers actually search before they book.

How much is aircon servicing in Singapore?

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.

What is included in normal aircon servicing?

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.

How long does aircon servicing take?

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.

How often should I service my aircon?

For normal residential use, ALV currently recommends around every three months. Systems that run for long hours each day may need more frequent servicing.

What is the difference between general servicing and chemical wash?

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.

Does aircon leaking water mean I need a chemical wash?

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.

Does an aircon that is not cold always need gas top-up?

No. Weak cooling can have several causes. Refrigerant should be checked as part of diagnosis rather than assuming every cooling problem needs gas.

What happens if the technician finds a repair is needed?

The technician can explain the issue and recommended repair. Repair work and replacement parts are separate from a normal servicing visit.

Do you service Daikin and Mitsubishi aircons?

Yes. ALV currently lists Daikin, Mitsubishi Electric, Mitsubishi Heavy Industries and several other major manufacturers among the brands it services.

Do you service HDB and condo aircon systems?

Yes. ALV services HDB flats, condominiums, landed homes and commercial properties.

Do you offer aircon maintenance contracts?

Yes. ALV offers monthly, quarterly, bi-annual and annual maintenance plans for residential and commercial properties.

Can I get same-day aircon servicing?

ALV currently advertises same-day and next-day appointment options, subject to booking time, location and technician availability.

What refrigerant types do you work with?

ALV services systems running R22, R410A and R32, matching the correct type to each system.
