Capacitors are available in a wide range of capacitance values, from just a few picofarads to well in excess of a farad, a range of over 10(^{12}). Unlike resistors, whose physical size relates to their power rating and not their resistance value, the physical size of a capacitor is related to both its capacitance and its voltage rating (a consequence of Equation ref{8.4}.

Best HVAC Capacitor Guide: How to Find the Right One
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.
