With new airconds costing RM1,000-3,000+, it's tempting to check Mudah, Carousell, or Facebook Marketplace for a second-hand unit at half the price. But is a used aircond actually a good deal, or are you buying someone else's problems?
Having serviced and repaired thousands of airconds — including many second-hand units bought online — here's our honest assessment.
The Appeal of Second-Hand
Used airconds typically sell for 30-60% of the new price. A 2-year-old Daikin 1.5HP inverter that retails for RM1,800 might sell for RM700-900 second-hand. For a rental property, temporary space, or tight budget, the savings are significant.
Before buying any used aircond, check for the signs that an aircond needs repair — unusual noises, weak airflow, water stains, or musty smells are all red flags that the unit has underlying problems.
Some sellers also include installation — "price with install" — making it a convenient one-stop solution.
The Risks Nobody Tells You About
1. Unknown History
You don't know how the previous owner used or maintained (or didn't maintain) the unit. An aircond that was never serviced for 3 years will have internal issues — clogged coils, low gas, worn bearings — that aren't visible from outside.
2. Gas May Be Low or Wrong Type
During removal and transport, refrigerant gas often leaks from connection points. Many second-hand units arrive with insufficient gas, meaning they'll cool poorly from day one. Topping up gas costs RM150-300 — already eating into your savings.
3. No Warranty
New airconds come with 1-year general warranty and 5-10 year compressor warranty. Second-hand units have zero warranty. If the compressor fails next month, you're paying RM800-2,000 for a replacement — on top of what you paid for the unit.
A common issue with second-hand units is low refrigerant. Ask the seller to run the unit for at least 30 minutes and check for signs of low gas — warm air, long cooling times, or ice on the copper pipe.
4. Outdated Technology
A 5-year-old non-inverter unit will cost significantly more to run than a new inverter model. The RM500 you saved on purchase could easily be lost in higher electricity bills within a year. Check our brand comparison guide to see current pricing — new budget inverters are surprisingly affordable.
5. Installation Quality
"Include installation" sellers are often handymen, not trained aircond technicians. They may skip proper vacuuming, use recycled gas, or install with improper piping — all of which cause performance problems and premature failure.
6. Hidden Defects
Common hidden problems in second-hand units: corroded evaporator coil fins, weak blower motor bearings (will fail within months), cracked drain pans, and micro-leaks in the refrigerant circuit that slowly drain gas over weeks.
🔍 If You Must Buy Second-Hand: Checklist
✅ Ask for the unit's age and service history
✅ Check the model number online to verify the age
✅ Insist on seeing the unit running before purchase (if possible)
✅ Check evaporator coil for corrosion (lift the front panel)
✅ Listen for unusual noises from the blower and compressor
✅ Check that the remote control works
✅ Budget an additional RM200-400 for servicing/gas after installation
✅ Only buy inverter models — non-inverter isn't worth it at any price
✅ Get installation done by a proper aircond technician, not the seller
Older second-hand units often use R22 refrigerant, which is being phased out and increasingly expensive to top up. Newer units use R410A or R32 — understand the differences in our guide on aircond gas types and how long they last.
When Second-Hand Makes Sense
- Temporary accommodation: Renting a place for 6-12 months and the landlord won't install aircond
- Unit is less than 3 years old: Recent models still have good lifespan remaining
- You know the seller: Friend or family member whose maintenance habits you trust
- Rental property owner: For a room you're renting out — minimal investment needed
When to Buy New Instead
- Your own home: You'll be using it for years. The warranty and efficiency of a new unit is worth the extra cost.
- The used unit is 5+ years old: At this age, you're buying someone else's retirement candidate.
- No service history available: Unknown maintenance is a red flag.
- It's a non-inverter: The electricity cost penalty makes it false economy.
The Maths: New vs Used
Let's compare a 4-year-old used Panasonic 1.5HP non-inverter at RM500 vs a new Midea 1.5HP inverter at RM1,300:
- Used unit: RM500 purchase + RM200 gas top-up + RM100 service = RM800. Expected lifespan: 3-5 more years. Monthly electricity: ~RM170 (non-inverter). No warranty.
- New Midea: RM1,300 (installed). Expected lifespan: 8-12 years. Monthly electricity: ~RM120 (inverter). Full warranty.
- Electricity savings per year: RM600. Payback of the RM500 price difference: under 1 year.
The new unit wins on total cost of ownership within the first year.
Get It Inspected Before or After Purchase
If you've already bought a second-hand aircond, or you're seriously considering one, we offer an inspection service. Our technician will check the unit's condition, gas level, electrical health, and give you an honest assessment of its remaining useful life.
Our inspection service is available across Rawang and all of KL/Selangor through our aircond inspection service.
When comparing the cost of a used unit plus installation versus buying new, check our installation cost guide — you might be surprised how affordable entry-level new units have become.
