Aircon Cleaning & Maintenance in Singapore

Aircon cleaning is an important service in Singapore due to the hot and humid climate. As a result of constant use of the air conditioning systems, they may accumulate dust, dirt, moisture and other contaminants, reducing their efficiency and lifespan, as well as posing health risks to occupants. Our professional aircon cleaning services in Singapore can help to clean the air filters, evaporator coils, condenser coils, and other part of the indoor as well as outdoor unit, check for gas leakage and help to prevent any major damage to the aircon by taking necessary actions.

In Singapore, general aircon servicing is a standard process of cleaning and maintenance service of the aircon. National Environment Agent of Singapore (NEA) recommends a standard aircon cleaning service every 3 months for environment safety, energy efficient and optimal cooling performance of the aircon.

What Aircon Cleaning Includes

"Aircon cleaning" covers four levels of job. Most homes need the first every few months and one of the deeper cleans once a year or when a problem shows up:

Types of aircon cleaning in Singapore and what each includes
Job	What is cleaned	When you need it
General service	Filters and front panel washed, coil surface and drain tray cleaned, drainage pipe vacuumed, condenser and gas level checked	Every 3 to 4 months
Chemical wash	Coil and blower treated with cleaning chemical on the wall, drain flushed	Weak cooling, a smell, or no deep clean in a year
Chemical hydro wash	Blower wheel and drain tray removed, coil and blower water-jet rinsed, unit stays on the wall	A dirty blower or musty smell
Chemical overhaul	Fan coil taken down and dismantled, every part soaked and scrubbed	Mould, leaks or smells a wash did not fix

General servicing is SGD 49.68 for one unit, transport included. Every service and unit count is listed on our aircon servicing price page.

Aircon Cleaning You Can Do Yourself

Rinsing a dusty aircon filter with a garden hose

Switch off at the isolator, lift the front panel and slide out the filters every 2 to 4 weeks.
Rinse the filters under the tap, let them dry fully in the shade, and slot them back in.
Wipe the front panel and louvres with a damp cloth.
Keep the outdoor condenser clear of laundry, plants and stored items so it can breathe.

Leave These to a Technician

The evaporator coil and blower wheel: household sprays leave residue, and bent fins cut airflow.
The drain tray and drainage pipe, which need flushing or vacuuming to clear.
Anything involving refrigerant gas or the electrical parts.
Spraying water into the unit, which can damage the PCB.

6-Step Aircon Servicing Process

At StringsSG, we follow a proven 6-step approach to general aircon servicing in Singapore — ensuring your unit runs efficiently and reliably.

1. Air Filter & Front Panel/Cover Cleaning
Dirty air filters can block airflow and strain the aircon. Technicians clean or jet-wash filters to restore optimal airflow.
2. Cleaning of Evaporator Coil
The evaporator coil can collect dirt, reducing efficiency. The technician cleans it using a soft brush or vacuum.
3. Drain Pan or Tray Cleaning
Clogged drain pans may lead to leaks. Technicians clean out debris from the pan to ensure proper drainage.
4. Vacuuming of Drainage Pipe
To prevent water backup, the drainage pipe is vacuumed to remove blockages that may disrupt water flow.
5. Outdoor Condenser Check
Technicians assess the outdoor unit’s performance and recommend cleaning if necessary, based on inspection or customer request (extra charges may apply).
6. Monitor Refrigerant Gas Level
Technicians check the refrigerant gas level if poor cooling is observed or upon client request, and may recommend top-up if needed.
