Questions Answered
Services FAQ
How much does aircon servicing cost in Singapore?
Coolbest charges S$50 for 1 unit, S$55 for 2 units, S$70 for 3, S$85 for 4, S$100 for 5, and S$115 for 6 units — a full servicing visit per home. Prices are published upfront with no surprise charges.
What's included in a standard aircon servicing?
Filter washing, evaporator coil wipe-down, drainage tray flush, blower wheel cleaning, vacuuming, and a drainage-pipe check. Chemical washing, gas top-up, and parts replacement are quoted separately.
When do I need a chemical wash instead of regular servicing?
Go for a chemical wash when cooling weakens despite regular servicing, the unit smells mouldy, you see black slime in the drainage, or the unit is 5+ years old and hasn't had one. Typical cadence: every 1–2 years for heavy use.
Do you offer a warranty on repairs?
Yes. Every repair and servicing job comes with a 90-day workmanship warranty. If the same fault recurs within 90 days, we come back at no cost.
Does aircon refrigerant need topping up every year?
No. Aircon is a sealed system — if it 'needs' regular top-ups, you have a leak. The right fix is to find and repair the leak, then refill. Providers who push annual top-ups without leak checks are a red flag.
What's included in a maintenance contract?
Scheduled general servicing at your chosen cadence (quarterly or yearly), priority response between visits, locked-in multi-unit pricing, and transparent scope (chemical wash and parts are quoted separately when needed).
