Our pricing principles
Fixed, not hourly. You pay per visit, not per hour we spend. A simple fix and a complex one cost the same service fee.
Written quote before work. Diagnosis fee separated from work fees. You approve the scope and cost before we start.
No surprise add-ons. If we find more than expected, we pause, explain, and re-quote. You choose whether to proceed.
Same pricing everywhere. No surcharges by postcode. West Region, Central Region — same rates.
Questions Answered
Pricing 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.
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.
