What are air capacitors?

Air capacitors are capacitors which use air as the dielectric medium located between conductive plates. The dielectric constant value of a material is a measure of the amount of electrical energy stored in a material for a given voltage. Since capacitors are devices used to store electrical energy, higher dielectric constants are favorable.

How do you attach a capacitor to an A/C unit?

Hold the capacitor in position with the bracket around it. Screw in the screw holding the bracket in place. Make sure the capacitor is held tightly onto the A/C Reconnect the wires to the capacitor prongs in the same position they were located on the previous capacitor.
