Cheapest Aircon Servicing Deals: How Much Does It Cost?
General aircon servicing in Singapore costs $25 to $40 per unit for a one-off visit in 2026, while quarterly contract packages bring this down to as low as $18–$22 per unit. Regular servicing every 3 months keeps your compressor efficient and prevents that dreaded water-drip and musty smell.
Here's what you should expect to pay — and where to save:
- General service (per unit): $25–$40 one-off, or $18–$22 on a contract.
- Chemical wash (per unit): $60–$90 — needed roughly once a year.
- Chemical overhaul (per unit): $150–$200 for a deep dismantle-and-clean.
- Gas top-up (R32): $80–$120 depending on pressure and leaks.
Shiok deal alert: Signing a quarterly servicing contract typically saves you 25–30% versus ad-hoc visits, and many firms throw in a free chemical wash on the fourth visit. That's a genuine win-win — cleaner air and fatter savings!
Installation Savings & Hidden Costs to Watch
Aircon installation in Singapore usually adds $300–$600 on top of the unit price, but the biggest deals bundle installation for free during major sales. The hidden costs that catch buyers out are extra copper piping, trunking length and bracket work — always confirm what's included!
Watch out for these common add-on charges before you sign:
- Extra piping: First 3–5 metres often free; then $15–$25 per additional metre.
- Trunking / concealing: $8–$15 per metre for a neat, hidden finish.
- Removal & disposal of old unit: $50–$120 — some merchants waive this during promos.
- Wall bracket & ledge work: $80–$150 for condenser mounting.
Don't miss: During the National Day Sale 2026 (SG61), retailers frequently bundle free installation + free removal of your old unit — that alone can save you $150–$250. Time your purchase and grab both!
