An aircon chemical wash is a deep cleaning process that goes far beyond what general servicing can achieve. Specialised cleaning solutions are applied to the evaporator coil and internal components to dissolve mould, bacteria, and stubborn organic buildup that surface-cleaning cannot remove. In Singapore's humid climate, mould growth inside the coil is the leading cause of musty smells, reduced cooling, and elevated electricity bills.

Kovan homes are typically Mixed residential. Whether you're in a BTO, resale flat, executive condominium, or landed home, our technicians have experience with the unit configurations common in this area.

Frequently asked questions

How much does aircon chemical wash cost in Singapore?
aircons.sg charges $135 for 1 unit, $245 for 2, $345 for 3, $425 for 4, and $100 per unit for 5 or more — the more units washed in one visit, the lower the per-unit rate. We do not charge GST, so the price you see is the price you pay.
How often should I do a chemical wash?
Every 6–12 months for daily-use residential aircon. More frequently (every 6 months) if anyone in your household has allergies or asthma, or if you run aircon for 8+ hours daily.
Is chemical wash safe for my aircon?
Yes, when performed by trained technicians using appropriate cleaning solutions. The chemicals used are designed for aircon coil materials and won't corrode aluminium fins. Cheap or improper chemicals can damage the unit — which is why pricing matters less than provider competence.
Will chemical wash fix my aircon not cooling problem?
Often, yes — if the cause is coil fouling, biofilm buildup, or drainage blockage. If the issue is gas-related (low refrigerant) or compressor failure, the 9-point pre-check (included with your service booking) will identify it and we'll recommend the correct fix instead. You'll get a transparent quote for any additional work before we proceed.
How long does a chemical wash take?
About 60 to 90 minutes per indoor unit, including the pre-check and final testing. A typical 3-bedroom HDB flat with 3 units is usually done in well under half a day.
Is an aircon chemical wash worth it?
If your unit smells musty, cools weakly, or has not been deep-cleaned in 6+ months, yes — a chemical wash restores cooling, clears the smell at its source and can lower running costs. If the unit is already clean and recently serviced, a routine general service is the more cost-effective choice, and our pre-check will tell you which you need.
Can I do a chemical wash myself?
We do not recommend it. A proper chemical wash involves isolating mains power, handling coil-safe chemicals correctly, and fully clearing the drainage system. The wrong chemical or an incomplete rinse can corrode the coil or leave the smell behind — and any DIY damage usually voids the manufacturer warranty.
Will a chemical wash get rid of the musty aircon smell?
In most cases, yes. That smell is mould and bacteria growing inside the coil and drain — exactly what the chemical wash and anti-bacterial treatment target. If the smell returns quickly afterwards, the drainage was likely not treated, which is a step we always include.
Do you charge extra for GST or transport?
No. aircons.sg does not charge GST, and standard transport within Singapore is included — the quoted price is the final price.
