Second-Hand Cooler, Geyser or Room Heater: Test It Before You Pay, and Buy in the Right Season

Seasonal appliances are among the most commonly traded used goods in Indian homes. A family upgrades its cooler, a student leaves a hostel, a tenant moves out with a geyser nobody wants to carry. They also have one thing in common: they look fine when switched off. A cooler with a cracked pump, a geyser with a leaking tank and a heater with a burnt coil all look healthy until power is connected. This guide gives you a short test routine for each, safety notes, and some thoughts on timing. For a broader appliance overview see our guide to buying second-hand appliances.

Timing: when to buy and when to sell

Demand follows the weather. Coolers tend to be sought before and during the hot months, geysers and heaters before and during the cold months. As a general pattern:
Selling is easier when the season is approaching, because buyers are searching.
Buying can be cheaper outside the season, when fewer people are looking, if you have storage space and the patience to wait.
This is a general pattern, not a guarantee, and it depends on your city's climate. Compare actual listings before you decide.

The test routine, appliance by appliance

Air cooler
Body — Cracks, rust, loose panels, a missing cover or wheel
Water tank — Fill it, and watch for leaks from joints and the drain plug
Pump — Run it; water should reach the pads evenly, without loud humming
Fan and motor — Run on all speeds; listen for rattling; look at blade wobble
Cooling pads — Check for stains, dried scale and tears; replacement pads cost extra
Switch and cord — Check the plug, the wire insulation and the switch response
Run the cooler for at least ten minutes. Stand in front of it and feel the air; a mild, steady, damp breeze is normal for a working cooler.
Geyser (water heater)
Tank and body — Dents, rust, water stains or drip marks around the joints
Inlet and outlet pipes — Fit, leakage, brittle fittings
Heating element — Ask when it was last replaced; heavy scale suggests hard water use
Thermostat — Water should heat up and the indicator should switch off when the set temperature is reached
Safety valve and plug — Ensure the pressure relief valve (if present) and a proper three-pin plug and earth wire exist
Power cable — No cracks or burn marks
Test with water only, and never switch on a geyser without water in the tank. If you are unsure, ask a licensed electrician or a plumber to look at it, and ask the seller for permission to do this before paying. Also ask where the unit was installed and how long ago.
Room heater
Coil or heating element — Even glow, no broken or sagging sections
Fan (if fitted) — Smooth, quiet running
Tip-over and overheat protection — Does it switch off if tilted, if such a feature exists
Plug and cable — No discolouration, no melted insulation
Smell — A faint dust burn-off at first is common; a persistent burnt-plastic smell is not
Keep it away from curtains and bedding while testing, and do not leave it unattended.

Safety first

Check the manufacturer's rating label and keep the brand and model for reference. If it is missing, be more careful.
Appliances that draw high power need a proper socket and plug. Do not use loose or damaged sockets.
If you see burn marks on the plug or cord, walk away.
Ask an electrician if the home wiring can handle the appliance. This matters especially for geysers.

What price to ask or pay

Instead of quoting a fixed number, compare three listings of the same make and age, and then move the price down for missing parts, repairs needed or an unknown history. A model with its original manual or bill is worth a little more to a careful buyer. Our sell old furniture guide explains how to compare similar listings.

A fair handover

Test the appliance with the buyer watching.
Be honest about any repair done and how old the appliance is.
Accept payment in a way that you can verify in your own account.
Remove the appliance's water completely before moving it, particularly the cooler tank and the geyser.
Offer a simple written note: item, date, condition as seen, amount received.

Safety tips

Meet in a public, well-lit place and, where possible, take someone with you.
Inspect the item before you pay and check it matches the listing.
Never pay in advance, share OTPs, or move payment outside the agreed meeting.
Keep contact through the listing page — contact details are privacy-gated in the app.
Report suspicious sellers instead of continuing the conversation.

Frequently asked questions

Is a second-hand geyser safe?

It can be if it passes the checks and is installed correctly by a qualified person. If the tank leaks or rusts, avoid it.

Should I replace the heating element in an old geyser or heater?

If the rest of the unit is sound, a new element can extend its life. Ask a technician about the cost before buying.

Can I transport a cooler with water in it?

Drain it fully first. Remaining water spills and can damage the pump.

Is a bill necessary?

It is helpful for confirming age and model but not mandatory in private sales.

How do I check if the geyser has the right capacity for my house?

Check the litre capacity on the label and compare it with your family's hot-water use.
