Town Square and Mudon residents — how does the district cooling work out here, and what should you watch on the bill?

District cooling in communities like Town Square and Mudon works differently from a split, and once you see the shape of it the bill makes sense too. Instead of each home having its own condenser, a central plant chills water and pipes it round the community; inside your home, fan coil units (FCUs) blow room air across that chilled water to cool it. So your comfort depends on two things: the building/community supplying good chilled-water flow, and your own FCUs being clean and working. Your bill has two parts, a consumption charge for the cooling you actually use, plus a fixed capacity (demand) charge for the connected capacity reserved for your home, which is why it isn't zero even in a mild month, explained in the thread on why a district-cooling bill runs high and how the two charges work. What's on you is the FCU side: keep filters and coils clean and the condensate draining. What's on the provider is the chilled-water supply. A district cooling service in Town Square that maintains the FCUs keeps your rooms cold and helps you tell a home-side issue from a supply one.
