Even though capacitors aren''t the first thing that comes to mind when HVAC systems are mentioned, using an AC, a furnace, or a heat pump without a capacitor isn''t possible. All HVAC systems come with built-in capacitors, and if one or more of the unit''s capacitors fail, the best course of action is to replace them with an identical model.
Most people who have a little DIY experience choose to replace their capacitors on their own. A typical AC unit capacitor will cost between $12 and $35 a pop, with some having a slightly higher price tag. Since this is generally a DIY-oriented repair, you shouldn''t expect to have to pay for any additional labor.
Understanding AC Capacitors. AC capacitors are essential components in your home''s air conditioning system, serving as a catalyst to start and maintain the operation of the motor. Understanding their function and recognizing the signs of a malfunction is crucial for maintaining a comfortable and efficient home environment. Role of AC Capacitors
The quantity (X_C) is known as the capacitive reactance of the capacitor, or the opposition of a capacitor to a change in current. It depends inversely on the frequency of the ac source—high frequency leads to low capacitive reactance. Figure (PageIndex{4}): (a) A capacitor connected across an ac generator.
The role of AC capacitors in your air conditioning system cannot be overstated.

Capacitors store energy in the form of an electric field. At its most simple, a capacitor can be little more than a pair of metal plates separated by air. As this constitutes an open circuit, DC current will not flow through a capacitor. If this simple device is connected to a DC voltage source, as shown in Figure 8.2.1, negative charge will ...
