Cased/Uncased and Configurations: You can choose between a cased and uncased coil, with the uncased coil coming without the protective case, making it easier to mold into different shapes that might benefit more unique air conditioning systems. These models also come in different configurations, like upflow, downflow, a combination of these, and on a slab, specifically meant to accommodate horizontal air conditioners. Tonnage: The tonnage of your air conditioning unit should match up with the tonnage of your evaporator coil. So, for example, if you have a 2-ton condenser inside of your air conditioning unit, the evaporator coil should also be 2 tons. Here is a useful guide to tonnage sizes: To find the desired tonnage for your evaporator coil, you? ll first need to calculate the square footage of the space that you? re trying to cool. Typically, the average home requires one ton of air conditioning per 400 to 1,000 square feet. There is a lot of variation in this number since you? ll also need to factor in how many windows the space has and how tall the ceilings are, as these things dictate how easily air flows through your space.
