Twenty-one years in commercial refrigeration across north Texas. My customers are restaurants, convenience stores and small groceries, and my phone rings at the hours when a walk-in cooler decides to quit. Nobody calls about a freezer at nine in the morning. When a walk-in is rising and you have thirty thousand dollars of product in it, the first decision is not the repair, it is whether you move the product and where. I walk people through that first, then through the triage: iced coil, failed condenser fan, low charge, or a defrost cycle stuck. Most of those you can identify by looking and listening, and two of them you can temporarily work around. I also do residential air conditioning, which in Dallas means June through September is one long emergency. If your system is freezing up or short-cycling, there are four checks you can do before anyone charges you a diagnostic fee, and I will take you through all four.
