In hot and sticky Singapore, air conditioning isn’t just nice to have. It’s a must-have to keep everyone comfortable. If you do not have enough money, buying a new AC is not always feasible. Choosing a reconditioned unit can be a great short term cost saving solution. Let’s discover the advantages and disadvantages of buying a 2nd air conditioner in Singapore.
Quick Comparison: Second-Hand vs New Aircons
Here are a few common differences between brand-new and reconditioned aircons:
| Factor | Second-hand aircon | New aircon |
| Upfront price | Lower; big savings possible | Higher |
| Energy efficiency | Often lower; depends on age and model | Highest with current inverter models |
| Lifespan remaining | Shorter and variable | Full manufacturer lifespan |
| Warranty | Limited; reseller-backed | Full manufacturer warranty |
| Repair risk | Higher; parts may be older or scarce | Lower initially |
| Availability | Immediate stock or used sets | Depends on stock and promotions |
| Sustainability | Reuse reduces waste | More efficient tech but new manufacturing footprint |
The Benefits of Buying a Second-Hand Aircon
Lower Upfront Cost
You can cool your home for far less than with a new unit. This is especially attractive for tenants, short-term stays, or tight renovation budgets.
Faster Availability
Used and reconditioned aircons are usually in stock, making installation faster—helpful during peak moving or renovation seasons.
Sustainability Benefits
Reusing aircon units helps extend their life and reduces electronic waste, making it an eco-friendly choice.
Compatibility with Older Systems
If you’re replacing part of an older system, a second-hand indoor or outdoor unit may help maintain compatibility with your existing trunking and piping.
Lower Depreciation Worries
Since it’s already used, cosmetic blemishes matter less—especially useful for rental units or heavy-use rooms.
The Drawbacks of Buying a Second-Hand Aircon
Shorter Remaining Lifespan
Even well-maintained units have already used part of their service life. Expect repairs or replacement sooner than with new models.
Higher Electricity Bills
Older or outdated inverter technology is often less energy-efficient. Over time, higher power bills can eat into your initial savings.
Limited Warranty and Support
Second-hand units often come with shorter warranties, usually from resellers instead of the manufacturer.
Unknown Service History
Without complete records, hidden issues like coil corrosion or refrigerant leaks may surface after installation.
Parts Availability and Noise
Older models may be noisier, and spare parts could be harder to source or more expensive.
FAQ
Is it worth buying a second-hand aircon in Singapore?
Yes, if you want to save money now, you only need it for a short time, or need something for a rental or a room that doesn’t get a lot of use. Just keep in mind it might cost you more in electricity because its energy efficiency may not be good enough, won’t last as long as a new one, and probably won’t have much of a warranty.
How can I check if a second-hand aircon is in good condition?
You should check your 2nd hand aircon thoroughly before buying. Inspect the indoor and outdoor units for corrosion, leaks, and physical damage. Check insulation, fan condition, and drain lines. Run a test for at least 15–20 minutes to ensure proper cooling, noise levels, and stable operation.
Are second-hand inverter aircons more efficient than older models?
Yes. Inverter aircons usually use less electricity than older, non-inverter units. Still, they might use more than a brand-new one. It depends on how old they are and how well they’ve been maintained.
What warranty can I expect with a second-hand aircon?
Most second-hand aircons come with a short reseller warranty. It typically covers 3–12 months for certain parts. Manufacturer warranties are usually not available for 2nd hand aircons.
Can I use a second-hand aircon in my HDB or condo?
Yes, but you must comply with HDB regulations for aircon installation, such as outdoor unit placement, drilling, and bracket installation.
How long can a second-hand aircon last?
The lifespan depends on the unit’s age, usage, and maintenance history. A well-serviced unit may last 5–8 years, but older or heavily used units may need replacement sooner.
Will a second-hand aircon cost more to run?
It can, especially if the unit is older, uses less efficient inverter technology, or has a higher energy rating. Always compare electricity costs over time to see if the savings are worthwhile.
Should I replace the piping when installing a second-hand aircon?
It’s recommended to replace old or corroded piping and insulation to prevent leaks and maintain efficiency. Reusing old piping may save cost but can lead to future problems.
