The cost of recharging the air conditioner with Freon starts from 40 euros. The price depends on the accessibility to the outdoor unit of the air conditioner, the amount of added refrigerant and the brand of refrigerant. For example, full refuelling of a split system up to 3 kW will cost the customer 150 euros. Very often freon comes out together with oil, which leads to compressor breakdown. On site, a High Service technician will determine whether there has been an oil leak from the line.
