Fridge refrigerant recharge: cost and what affects it
The price depends on the refrigerant type (R134a, R600a, R290), system volume, and how tricky the leak is. See the table for prices.

| Thermostat replacement (fridge) | 200–400 zł |
| Fan replacement (fridge) | 300–400 zł |
| Sensor replacement (fridge) | 300–350 zł |
| Defrost heater replacement (fridge) | 350–550 zł |
| Refrigerator refrigerant recharge | 300–700 zł |
| Refrigerator compressor replacement | 500–1200 zł/szt |

How it works
- You say so in the order the symptoms: weak cooling, compressor running all the time, or switching on and off too often.
- The technician comes with a gauge manifold and gas detector.
- Tradespeople check system pressure: to confirm the leak.
- Tradespeople find the leak using a gas detector or soap solution.
- Repair: braze the copper tube or swap the damaged section.
- Evacuate the system (remove air and moisture) — at least 20 minutes.
- Fill in the exact amount of refrigerant by weight (according to model specs).
Mistakes
- Adding gas without repairing the leak: it will be gone again in a week.
- Charging by guesswork instead of by weight: too much refrigerant is just as bad as too little.
- Skipping vacuum — moisture ruins the compressor within months.
- Mixing it up with a thermostat problem: with a leak the back wall stays warm; with a thermostat fault it stays cold.
- DIY with internet cans: without vacuum and brazing, it makes no sense and can be dangerous (R600a is flammable).
Fridge refrigerant recharge: getting ready
- Fridge model.
- When it started.
- Take the food out.
- Unplug it.
- Access from the rear — they work on the tubes.
- Photo of the model sticker and data plate (it shows the refrigerant type).
- Air out the kitchen (R600a needs that).
- Set aside 2–4 hours.
Case from Warsaw
Client in Targówek: Liebherr: compressor running non-stop, fridge at +14°C. Condenser hardly warm. The gauge showed near-zero pressure. Tradespeople found a micro-crack at the factory braze on the compressor line: damage from vibration. Brazed it, vacuumed for 30 minutes, charged 55g R600a to spec. After 2 hours — fridge +4°C, freezer -18°C. 3 hours total. Tip: if your fridge slowly loses cooling over a few weeks, that’s a classic sign of a slow refrigerant leak.
FAQ
What is refrigerant?
A gas moving through a sealed system that carries heat from inside the compartment to the outside. Without it, the fridge won’t cool.
Why does it leak?
Micro-cracks from vibration, corrosion on the tubes, factory brazing faults.
Can I just top up?
No: first the leak has to be repaired, otherwise the gas will escape again.
Is R600a flammable?
Yes: it’s isobutane. The amount inside a fridge (30–60g) is safe, but the room must be ventilated and there can’t be any open flames during the job.
Time?
2–4 hours.
Brands?
Samsung, LG, Bosch, Siemens, Liebherr, Whirlpool, Beko, Indesit.
Expensive?
Costs more than a thermostat, but less than a compressor.
How long will it last?
For years — if the leak is repaired properly.
DIY?
No: you need a gauge manifold, vacuum pump, gas detector, and brazing skills. R600a is flammable.
Who does the work
Refrigerant recharge is done by technicians with refrigeration tools. Tradespeople cover all of Warsaw. Fridge not cooling?
