Chilled Water Coils, Replacement Coils, HVAC coils for all seasons from the official Nationwide Coils Inc.

Cooling coils come in a variety of shapes and sizes, depending on the type of installation, the amount of cooling capacity needed, and the manufacturer. It is the source of cooling as air passes through the furnace or air handler. They are constructed of aluminum finned copper tubing. The copper tubing runs perpendicular to the aluminum fins, making U-turns back and forth until the desired coil size is achieved. Added cooling capacity without an increase in length and width is accomplished by adding more rows of copper tubing.
