Frequently asked questions

Chemical wash vs chemical overhaul — which do I need?

Chemical wash cleans the coil without disassembly — good for routine deep cleaning every 6–12 months. Chemical overhaul fully dismantles the unit and cleans every component individually — recommended every 2–3 years, or sooner if your unit has serious fouling, persistent odour, or hasn't been overhauled in years.

How much does a full HDB aircon overhaul cost?

For a typical 3-bedroom HDB flat with 3 fan coil units, a full chemical overhaul costs $515 at aircons.sg (prices are final). 4-bedroom flats with 4 units cost $640. Pricing covers complete disassembly, individual component cleaning, and 90-day warranty.

Will chemical overhaul make my aircon work like new?

For units under 8 years old in good mechanical condition, yes — overhaul can restore most of the original cooling performance. Older units or those with worn compressors will improve significantly but may not fully recover original specs.

How long does a chemical overhaul take?

About 2 to 3 hours per indoor unit, because each part is removed and cleaned individually. A full 3-unit HDB flat is usually a half to full day depending on access and unit condition.

Is a chemical overhaul worth it for an older aircon?

If the unit is under about 8 years old and mechanically sound, yes — it is the deepest clean available and far cheaper than replacement. If the pre-check shows a failing compressor or end-of-life unit, we will tell you honestly so you can weigh overhaul against a new installation.

Do you need to remove the unit from the wall?

Yes. On a chemical overhaul the whole wall unit is taken off the wall, stripped, and every part is chemical washed. It is then reassembled, refitted and tested. A chemical wash is the job that leaves the unit on the wall.

My aircon still smells after a chemical wash — will an overhaul fix it?

Usually, yes. A persistent smell after a wash means mould or debris is sitting in the blower wheel, casing or deep in the drain tray — exactly the areas an overhaul strips down and cleans individually.
