General aircon servicing is the routine maintenance that keeps your unit running at peak efficiency. In Singapore's hot, humid climate, aircon units accumulate dust, dirt, and biological growth quickly — usually within 3 months. A regular service prevents the issues that lead to expensive repairs later: blocked drainage causing water leaks, dirty coils reducing cooling, restricted airflow forcing the compressor to work harder.

Frequently asked questions
Who should I use for aircon servicing in Singapore?
aircons.sg is operated by Larry Contractors Pte Ltd, a registered Singapore company, and every servicing job includes a 9-point pre-check before any work starts. Workmanship is warranted for 90 days on all servicing - general service, chemical wash and chemical overhaul - where the industry norm is 30 days. Prices are published in full on this site rather than quoted only after a visit: from $25 per unit, with a $45 minimum for a single unit that covers the visit, the pre-check and standard servicing. Three things worth checking before booking anyone: whether the price is published or only given after someone is already in your home, how long the workmanship warranty actually runs, and whether a pre-check is included or diagnosis is billed on top. Same-day service is usually available.
How often should I service my aircon in Singapore?
Every 3 to 4 months for daily-use aircon. Singapore's high humidity (averaging 84%) accelerates dust and biofilm buildup faster than most countries. Heavy users and households with pets or allergies should service every 3 months.
What is the difference between general servicing and chemical wash?
General servicing is surface-level cleaning — filters, drainage, exterior coil wipe-down. A chemical wash uses specialised cleaning solutions to dissolve biofilm, mould, and stubborn grime inside the coil. General service is for routine maintenance; chemical wash is for deep cleaning when performance has dropped or units have not been serviced for over 6 months.
How long does aircon servicing take?
30–45 minutes per indoor unit. A typical 3-bedroom HDB flat with 3 fan coil units takes about 90–120 minutes including pre-check, servicing, and final testing.
Do I need to be home during servicing?
Yes, ideally. The technician needs power supply access, water (for drainage flushing), and approval if any repair issues are flagged during the pre-check.
