How to Prepare Your Aircon Before a Long Holiday

Going on a long holiday is exciting, but before you leave, it’s important to make sure your home appliances are safe — especially your aircon. Many homeowners in Singapore forget that an unused aircon can still develop mould, leaks, or electrical issues if it isn’t shut down properly. Preparing your system takes only a few minutes and can prevent unnecessary repair costs when you return. Here’s what you should do before going away for an extended trip. ### 1\. Clean or Replace Your Air Filters Dirty filters trap dust and moisture, increasing the risk of mould growth when the aircon sits unused. Cleaning them beforehand keeps the system fresh and prevents musty smells later. **Benefits:** - Reduces mould growth - Keeps indoor air fresh - Prevents strain on the system when you restart it ### 2\. Run the Aircon in Fan Mode for 20–30 Minutes Before switching off completely, let the system run in **Fan Mode**. This helps dry up moisture inside the cooling coil and blower fan. **Why it matters:** Moisture left inside is the biggest cause of mould, mildew, and bad odours when the aircon is not used for weeks. ### 3\. Check for Leaks or Blocked Drainage If your aircon has been leaking recently or you notice water dripping from the indoor unit, fix it before you leave. A clogged drain pipe can worsen over time and even cause water damage in your home while you’re away. **Tip:** Schedule servicing if you’ve noticed: - Gurgling drain pipe sounds - Slow dripping - Damp smells near your unit ### 4\.
