You will see a 4-6 inch plastic or metal box mounted on the outside of your air handling unit near the evaporator coil, and it will have a power cord attached to it. The bulb is replaced by sliding out a long light tube from the box. The purpose of the UV light is to prevent mold from growing on the evaporator coil inside your unit. This is on the A/C unit located inside your house or in the garage. The evaporator coil is located where the 2 copper pipes connect to the unit.
