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.

Bishan homes are typically HDB premium. 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.
