Frequently Asked Questions
- How much does an aircon chemical overhaul cost in Singapore?
- An aircon chemical overhaul in Singapore costs S$60–S$220 per unit, with an average of around S$140 per unit based on prices from 43+ companies. It is more expensive than a chemical wash because it involves full disassembly.
- What is an aircon chemical overhaul?
- A chemical overhaul is the most thorough aircon cleaning method. The indoor unit is fully disassembled and every component — evaporator coil, fan blower, drainage tray, and casing — is soaked in chemical solution, rinsed, dried, and reassembled. It restores the unit to near-new condition.
- When do I need a chemical overhaul?
- A chemical overhaul is recommended when your aircon has heavy mould buildup, persistent bad smell after a chemical wash, reduced airflow, or has not been deep-cleaned in 2–3 years. It is also advisable before moving into a resale flat or after a long period of non-use.
- How is a chemical overhaul different from a chemical wash?
- A chemical wash cleans the unit in place without full disassembly and is suitable for annual maintenance. A chemical overhaul involves complete disassembly and is recommended for heavily soiled units or as a 2–3 year deep-clean. Overhauls cost more but provide a more thorough result.
- How long does a chemical overhaul take?
- A chemical overhaul for one unit typically takes 1.5–2.5 hours. For 3–5 units, expect a half-day appointment (3–5 hours).
