- Price transparency: per-unit prices for general servicing, chemical wash and chemical overhaul.
- GST clarity: whether the published price is the final price.
- Warranty: a stated number of days on workmanship.
- Certification: bizSAFE, ISO or other credentials named on the site.

What is the difference between general servicing, chemical wash and chemical overhaul?
General servicing cleans filters, coils and drainage and is the routine job. A chemical wash cleans the fan coil with chemical solution while the unit stays mounted. A chemical overhaul dismantles the fan coil for a deeper clean, and costs the most.
Most homes book general servicing regularly and a chemical wash or overhaul when the unit leaks, smells or cools poorly. The published prices above show the gap: at Lion City Aircon a single general service is S$49.05, a chemical wash S$87.20 and an overhaul from S$109; at aircons.sg the single-unit figures are S$45, S$135 and S$200. Prices per unit fall when you service several units in one visit, and annual contracts are cheaper again: Lion City lists an annual contract at S$174.40.
How much does aircon servicing cost in Singapore?
Among companies here that publish prices, a single general service costs S$45 to S$55, falling to about S$20 to S$25 per unit for five or more units. Chemical washes start from S$87.20 to S$135 a unit, and overhauls from S$109 to S$200.
Watch the GST line. Lion City Aircon, GoodCool and @bsolute Aircon state that prices include GST. Cool Aircon says it adds no GST and no call-out fee. aircons.sg says its quoted price is the final price. Ceiling cassette units, larger BTU ratings and gas top-ups cost more, so describe your units when asking for a quote.

Frequently asked questions
How often should I service my aircon in Singapore?
It depends on how often you run the units. Units used daily need general servicing more often than spare-room units, and a chemical wash makes sense when cooling drops or the unit leaks. Ask the technician to suggest an interval after the first visit.
Is a chemical overhaul worth it?
An overhaul cleans more thoroughly than a chemical wash because the fan coil is dismantled. It costs more, so it is usually kept for units with heavy build-up or recurring problems.
Do aircon servicing prices include GST?
Not always. Lion City Aircon, GoodCool and @bsolute Aircon state GST-inclusive prices, while Cool Aircon says it adds no GST. Confirm the final amount before the technician starts.
What warranty should I expect?
Among companies here that state one, servicing warranties are 30 to 90 days on workmanship. Installation warranties are longer, up to 5 years for designated brands at Jiaxing.
How did you choose the order?
We weighed price transparency, GST clarity, written warranty and certification, using only what each company publishes. We update the list when those facts change.
