The panels are typically positioned in the form of an “A.” These panels are lined with thin pieces of metal known as “fins,” which bring the passing air to be cooled closer to the coils in order to maximize the effect of the refrigerant. The evaporator coil, condenser coil, and compressor work together to move the refrigerant from the outside to inside in a continuous loop of heat exchange and transfer. In many cases, a smaller coil can increase the humidity removal by 30% to 40% resulting in greater dehumidification. Your air distribution system then distributes the cooled air through your home or business. Further to this explanation, in an ideal HVAC unit the two sets of coils are designed to match one another.

Dirty evaporator coils can cause the refrigerant to freeze. The temperature of the refrigerant rises as the molecules press closer together. The coil size determines this ratio. This is where the refrigerant releases much of the heat that was absorbed from your home. The evaporator coil is located inside or near the air handler where the blower fan is. Changing coil size is a trade off in that if you remove more latent heat, you remove less sensible heat (measurable temperature). The weaker the coils, the more prone they are to developing refrigerant leaks. As the refrigerant evaporates, it removes heat from the surrounding air. From there, it flows back through a copper tube into your home and into the expansion valve located in the indoor unit near the evaporator coil. For more information, call us today at 770-450-6001.
