If you’ve ever booked aircon servicing in Singapore, you’ve probably wondered — how long does it take? Whether you’re a homeowner, tenant, or office manager, knowing the servicing time helps you plan your day better.
The truth is, it depends on several factors — the type of service, the number of aircon units, and the condition of each one.
Let’s break down how many hours aircon servicing usually takes and what can affect the total time.
1. General Aircon Servicing (30–60 minutes per unit)
General aircon servicing is the most common type of maintenance. It includes cleaning the air filters, vacuuming the drainage pipe, and checking the refrigerant pressure.
👉 Typical Duration: 30–60 minutes per unit
This service is quick and ideal for aircons that are well-maintained. It helps your unit cool efficiently and use less energy. If you get servicing every 3 to 4 months, the process stays simple and fast.
Example: For a 3-unit HDB flat, expect the entire session to take about 1.5 to 2 hours.
2. Aircon Chemical Wash (1–2 hours per unit)
A chemical wash takes longer because it involves dismantling parts of the indoor unit. The technician removes the evaporator coil, fan blower, and filters for deep cleaning using a chemical solution.
👉 Typical Duration: 1 to 2 hours per unit.
This process clears stubborn dirt, mold, and bacteria that normal cleaning can’t reach. It’s recommended for units that have not been serviced in over 6 months or are showing reduced cooling.
If you schedule multiple units, your aircon chemical wash in Singapore can take up to 4–5 hours in total.
3. Chemical Overhaul (2–3 hours per unit)
A chemical overhaul is a complete dismantling of your aircon unit. Every part — including the fan motor, coil, and drainage system — is cleaned, rinsed, and reassembled.
👉 Typical Duration: 2 to 3 hours per unit.
This is a more detailed service meant for aircons that are leaking, have poor airflow, or have not been cleaned for years. It restores your unit’s performance close to new and prevents costly breakdowns.
If your aircon is very old, a chemical overhaul Singapore service might take longer due to corroded or stuck parts.
4. Aircon Gas Top-Up (20–30 minutes per unit)
When your aircon is low on refrigerant, a gas top-up is needed to restore cooling.
👉 Typical Duration: 20–30 minutes per unit.
This process is quick, but it should always be done by certified technicians. They’ll first inspect for gas leaks before refilling.
5. Multi-System or Office Servicing (3–6 hours total)
For larger homes or office spaces, servicing multiple aircons takes longer. The technician team usually handles several units at once.
👉 Typical Duration: 3 to 6 hours depending on the number of units.
To minimize downtime, most aircon servicing companies in Singapore deploy multiple technicians to complete the job faster.
What Affects Aircon Servicing Time?
Several factors can make your aircon servicing longer or shorter:
Number of aircon units (more units = more time)
Condition of the aircon (dirty filters or clogged coils take longer)
Type of service (general vs. chemical overhaul)
Accessibility (units near ceilings or corners take more effort)
Technician team size (more technicians = faster work)
💡 Pro Tip
To save time, book your aircon servicing Singapore in advance and ensure your units are easily accessible before technicians arrive. If your schedule is tight, request a same-day servicing or express cleaning option.
The time needed for aircon servicing in Singapore depends on the service type and number of units. General servicing takes less than an hour per unit, while deep cleaning like chemical wash or overhaul takes longer.
