Aircon Chemical Wash
A chemical wash goes deeper than regular servicing. Where a general service cleans filters and flushes drainage with water, a chemical wash uses chemical solutions to break down stubborn dirt, mould, and bacteria buildup that water alone can't touch — especially inside the evaporator coil and drain pan. This is the service most Singapore homeowners need but skip, usually because the aircon still "seems fine" until the musty smell or weak cooling makes it obvious. If it's been 6 months or more since your last deep clean, or your unit smells off the moment it switches on, this is the fix.

Common Questions
General servicing cleans the filters and flushes the drainage with water. A chemical wash goes deeper — we use chemical agents to dissolve mould and bacteria buildup inside the evaporator coil, which can't be removed with water alone.
Once or twice a year is typical for most Singapore households. If you run your aircon heavily, have pets, or live near construction dust, once every 6 months is recommended instead of annually.
If the underperformance is due to dirty coils, yes — chemical wash usually resolves it. If it's a refrigerant leak or compressor issue, our technician will diagnose this during the visit and advise honestly rather than just doing the wash and hoping.
We use standard HVAC-grade cleaning chemicals that are safe for residential use. The unit is thoroughly rinsed before reassembly. There's no residual smell or health risk once the aircon is running again.
A chemical wash cleans the coil and internals in place without removing the unit. If your aircon still smells musty or performs poorly after a wash, or hasn't had a deep clean in 2-3 years, a full chemical overhaul (which dismantles the entire unit) is usually the next step.
In many cases yes, especially if the leak is caused by a clogged drain pan or blocked drainage pipe from mould buildup. Our technician will check this specifically during the service.
