Hello! My name is Sandy and I am the proud owner of a cafe which is located in Sydney, Australia. As you can imagine, things can get pretty hot here when the summer sun shines. Due to the high temperatures, I have to keep all of the food and drink in my cafe nice and chilled. To achieve this, I invested in some large refrigerated units. However, last summer, we had some real problems with them. I called out an engineer and he explained that I hadn't been taking proper care of my appliances. He repaired them and gave me some great tips which I would like to share with you all now.
