Why are some aircon companies so much cheaper?
A few reasons: cheaper companies often skip the pre-check (so you pay even if servicing won't fix your issue), use lower-grade chemicals (which can corrode coil fins), or employ undertrained technicians (warranty claims become disputes). When comparing, always ask: is there a workmanship warranty? Is pre-check included? Is the quoted price the final price, or are there add-ons?

Do you charge for parking or transport?
Standard transport within Singapore is included. The only exceptions are restricted parking zones (CBD/Marina Bay area) where a small surcharge ($10–20) applies if commercial parking is required.
