Buying used appliances in Thailand: aircon, fridges, washers, fans
Big used appliances can save real money, but they hide problems more easily than almost anything else you'll buy secondhand — you can't tell from the outside how much life is left in a compressor or motor. Here's how to test them on the spot and what hidden costs to plan for.

1. General rule: always see it running
Whether it's an air conditioner, fridge, washer, or fan, never buy from photos alone. Go see it at the seller's place or ask them to plug it in and run it in front of you. If a seller says 'it's already been unmounted so I can't plug it in' or 'the aircon is still on the wall, come see it later,' treat that as a warning sign — it's a common excuse when something is broken.
Run it for at least 15-20 minutes to confirm it performs consistently, not just that it starts and then cuts out or makes odd noises soon after.
2. Air conditioners: test the cooling and check the compressor
Ask the seller to run the unit for at least 15 minutes, then measure the air temperature at the outlet with a thermometer or your phone's sensor — it should read clearly cooler than room temperature. Listen to the outdoor compressor unit for unusual vibration or rattling, and look for oily residue along the copper pipes, which points to a refrigerant leak.
A 3-5-year-old used aircon typically costs ฿3,500-9,000 depending on BTU size, usually excluding installation and a deep clean. Budget an additional ฿2,000-4,500 for reinstallation and ฿800-2,000 for a refrigerant top-up if a leak turns up.
3. Refrigerators: listen to the compressor and check the door seal
Plug it in and let it run for at least 30 minutes. Feel inside the freezer compartment to confirm it's actually forming ice and running cold. Check the rubber door gasket for wear that would let warm air in, since a worn seal significantly raises electricity use, and look for the energy label rating to estimate the monthly running cost.
A 3-5-year-old, 5-7 cubic-foot used fridge usually sells for ฿2,500-6,000. A unit with an unusually loud or vibrating compressor should be negotiated down hard or skipped entirely, since compressor repairs often cost more than a cheap new fridge.
4. Washing machines: run a full cycle and check for vibration
Ask to run a complete wash cycle. Watch for excessive vibration during the spin cycle, listen to the motor, check under the machine for leaks after the cycle finishes, and inspect the door seal or top-loader drum for heavy mould buildup. A strong musty smell usually means years of poor maintenance.
A used top-loader with 7-9 kg capacity, three to four years old, typically runs ฿2,000-4,500. A used inverter front-loader runs ฿4,000-9,000 depending on brand and age.
5. Fans: the details people skip
Test every speed setting and, for oscillating fans, listen to the swing mechanism for grinding or excess vibration. Check the cord and plug for scorch marks or cracked insulation. Used fans typically run ฿200-700 depending on size and brand — arguably the best value secondhand appliance, since the motor is simple and cheap to repair.
6. Energy labels and the long-run electricity cost
Older units without a 'No. 5' energy label, or models made before around 2015, typically use 20-40% more electricity than current models even if the purchase price is lower. Do a rough calculation of the extra monthly running cost against the money saved upfront, especially for an aircon or fridge that runs every day, all year.
7. Installation and moving costs to budget for
Air conditioners need a specialist installer; typical installation runs ฿1,800-4,500 depending on pipe length and which floor you're on. Fridges and washers usually need a pickup truck for around ฿300-800 within Bangkok. For a high-rise condo, check the service lift booking rules with the juristic office in advance — many buildings only allow large item moves during specific windows.
