Prices for recharging an air conditioner with Freon start at 40 euros. The cost may vary depending on the access to the external unit, the amount of added refrigerant and its type. For example, a full refuelling of a split system with a capacity of up to 3 kW costs 160-200 euros. Often when freon leaks, oil is also lost, which can lead to compressor failure. High Service specialists will determine on site if there is an oil leak.
