So in this house in Vietnam we don't have central air. That is uncommon here. They use split units mounted on the walls high. The one in our master bedroom was beginning not make cold air. I already knew the issue was low Refrigerant. So she called the guy about an hour and a half ago and he came out here cleaned it, checked it recharged it and he just left. The bill was $500,000 Dong which is about 20 bucks USD..... :lol:
