Aircon Inspection Before Buying a Home in Singapore: What to Check, and What It Is Worth Off the Price
Before signing the Option-to-Purchase for a Singapore resale home, buyers should inspect the aircon system for age, mould, rust, and service history, as hidden aircon costs typically run S$2,000 to S$8,000 in the first year. A ten-minute self-check at the second viewing, combined with a S$150 to S$300 professional inspection for older or ducted systems, can reveal documented findings that justify S$500 to S$5,000 off the OTP price. Sellers in broker-managed transactions rarely walk away from a repair credit when confronted with clear evidence, making aircon inspection one of the highest return-on-effort steps in the Singapore home-buying process.
