Aircon Servicing Singapore — General Maintenance & Cleaning

For most Singapore households where aircon runs 8 or more hours daily, we recommend aircon servicing every 3 to 4 months. This frequency keeps filters clean, drainage clear, and cooling efficient. For lighter use — such as a bedroom unit used only at night — every 4 to 6 months is acceptable. Homes with pets, smokers, or units facing dusty roads may benefit from more frequent servicing as filters clog faster. Setting a regular aircon servicing schedule is the most cost-effective way to avoid emergency breakdowns and maintain energy efficiency year-round.

About 20 to 30 minutes per indoor unit for a thorough job. A typical HDB flat with 3 indoor units takes about 1 to 1.5 hours. We schedule sufficient time so nothing is rushed — every item on our servicing checklist is completed properly.

Yes, we recommend being present so we can show you any issues found during servicing and get your approval for any additional work if needed. We also walk you through what was done and provide advice on maintaining your aircon between servicing appointments.

If cooling issues persist after general servicing, the problem is likely beyond what routine cleaning addresses. Common causes include low refrigerant gas due to a leak (requires gas top-up after leak repair), a faulty compressor, a defective thermistor or PCB board, or a fan motor that is losing efficiency. These issues require targeted aircon repair and troubleshooting rather than general servicing. Contact us and we will diagnose the specific cause.

We provide aircon servicing for all major brands available in Singapore homes and offices, including Daikin, Mitsubishi Electric, Panasonic, LG, Samsung, Fujitsu, Midea, and Toshiba. Our technicians are experienced with the specific designs, filter types, and common issues associated with each brand. We also service less common brands — contact us with your unit details.

Yes, we service all aircon unit types including wall-mounted split units (the most common in HDB flats and condos), ceiling cassette units (popular in offices and larger living areas), concealed ducted systems (found in landed homes and commercial fit-outs), and portable units. Each unit type has a different servicing procedure and access method, and our technicians are experienced with all of them.

Yes, running your aircon for at least 15 minutes before the servicing appointment helps the technician assess cooling performance under operating conditions, check for unusual sounds, and identify issues like water leaks that only appear when the unit is running and producing condensation.

General aircon servicing is routine maintenance — cleaning filters, clearing drainage, wiping the evaporator coil surface, and performing system checks. It addresses surface-level dirt and is sufficient for regularly maintained units. Chemical wash uses specialised cleaning solutions to dissolve stubborn dirt, mould, and bacteria deep within the evaporator coil and blower fan that general servicing cannot reach. Choose general servicing for regular upkeep every 3-4 months. Choose chemical wash if your aircon has persistent issues after general servicing, produces a musty smell, or has not been maintained in over a year.

Yes. A dirty aircon works significantly harder to achieve the same cooling — dirty filters alone can increase energy consumption by 5 to 15 percent because the blower fan must push air through clogged material. A layer of grime on the evaporator coil reduces heat exchange efficiency, forcing longer compressor run cycles. In Singapore where electricity costs are among the highest in Southeast Asia, the cumulative savings from regular aircon servicing — typically 15 to 25 percent lower energy consumption compared to a neglected unit — more than offset the cost of servicing over time.
