2008 Inspection of car AC compressor leaks with the best refill method and highest quality materials. From Belgian oil and American freon. We provide all car compressors. Compressors are available for most cars with dismantling and installation. We refill using a scale to ensure pure freon, and you'll leave our shop praying for us. Unfortunately, most workshops in the industrial area refill freon and air, and you'll be back to them every summer. The freon gas is in a closed circuit; its cooling should not decrease over time, and it shouldn't cool sometimes and not others. It doesn't leak (unless affected by a reason). In short, it will last you for years. (The story of 'put your hand on the air, and if it cools, the gas will stop' - this method is only used for those who have a leak and want something to get them by because they don't have the cost to fix the problem).
