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.
