I have found voucher for AC refilling in Groupon at this garage. I never find it before. So I went there, guys said okay, we're on it. They've refilled it in 10-15 mins which surprised me. Okay, they said all good, ac works fine. So I left as a happy customer. Week later my ac stopped "cooling" and compressor started making weird whistling nosies. I went to the local garage and they found out that people in motcastlevale refilled ONLY 200ML of 650ML gas required! Also they even haven't checked the level of the oil in compressor which was 2ml of 20ml required. Avoid those pricjs as they look only for easy money.
